Debug libraries will be named libdumbd, release libraries libdumb. -* BUILD_SHARED_LIBS selects whether cmake should build dynamic or static library (On=shared, OFF=static) -* You may also need to tell cmake what kind of makefiles to create with the "-G" flag. Eg. for MSYS one would say something like `cmake -G "MSYS Makefiles" .`. diff --git a/libraries/dumb/include/dumb.h b/libraries/dumb/include/dumb.h deleted file mode 100644 index 14cf184df..000000000 --- a/libraries/dumb/include/dumb.h +++ /dev/null @@ -1,810 +0,0 @@ -/* _______ ____ __ ___ ___ - * \ _ \ \ / \ / \ \ / / ' ' ' - * | | \ \ | | || | \/ | . . - * | | | | | | || ||\ /| | - * | | | | | | || || \/ | | ' ' ' - * | | | | | | || || | | . . - * | |_/ / \ \__// || | | - * /_______/ynamic \____/niversal /__\ /____\usic /| . . ibliotheque - * / \ - * / . \ - * dumb.h - The user header file for DUMB. / / \ \ - * | < / \_ - * Include this file in any of your files in | \/ /\ / - * which you wish to use the DUMB functions \_ / > / - * and variables. | \ / / - * | ' / - * Allegro users, you will probably want aldumb.h. \__/ - */ - -#ifndef DUMB_H -#define DUMB_H - - -#include -#include - -#if defined(_DEBUG) && defined(_MSC_VER) -#ifndef _CRTDBG_MAP_ALLOC -//#define _CRTDBG_MAP_ALLOC -#endif -#include -#endif - -#ifdef __cplusplus - extern "C" { -#endif - - -#define DUMB_MAJOR_VERSION 1 -#define DUMB_MINOR_VERSION 0 -#define DUMB_REVISION_VERSION 0 - -#define DUMB_VERSION (DUMB_MAJOR_VERSION*10000 + DUMB_MINOR_VERSION*100 + DUMB_REVISION_VERSION) - -#define DUMB_VERSION_STR "1.0.0" - -#define DUMB_NAME "DUMB v" DUMB_VERSION_STR - -#define DUMB_YEAR 2015 -#define DUMB_MONTH 1 -#define DUMB_DAY 17 - -#define DUMB_YEAR_STR2 "15" -#define DUMB_YEAR_STR4 "2015" -#define DUMB_MONTH_STR1 "1" -#define DUMB_DAY_STR1 "17" - -#if DUMB_MONTH < 10 -#define DUMB_MONTH_STR2 "0" DUMB_MONTH_STR1 -#else -#define DUMB_MONTH_STR2 DUMB_MONTH_STR1 -#endif - -#if DUMB_DAY < 10 -#define DUMB_DAY_STR2 "0" DUMB_DAY_STR1 -#else -#define DUMB_DAY_STR2 DUMB_DAY_STR1 -#endif - - -/* WARNING: The month and day were inadvertently swapped in the v0.8 release. - * Please do not compare this constant against any date in 2002.

(But please don't complain - about differences between DUMB and ModPlug Tracker; see docs/modplug.txt) - -- Accurate support for low-pass resonant filters for IT files - -- Very accurate timing and pitching; completely deterministic playback - -- Click removal - -- Facility to embed music files in other files (e.g. Allegro datafiles) - -- Three resampling quality settings: aliasing, linear interpolation and cubic - interpolation - -- Number of samples playing at once can be limited to reduce processor usage, - but samples will come back in when other louder ones stop - -- All notes will be present and correct even if you start a piece of music in - the middle - -- Option to take longer loading but seek fast to any point before the music - first loops (seeking time increases beyond this point) - -- Audio generated can be used in any way; DUMB does not necessarily send it - straight to a sound output system - -- Can be used with Allegro, can be used without (if you'd like to help make - DUMB more approachable to people who aren't using Allegro, please contact - me) - -- Makefile provided for DJGPP, MinGW, Linux, BeOS and Mac OS X - -- Project files provided for MSVC 6 - -- Autotools-based configure script available as a separate download for - masochists - -- Code should port anywhere that has a 32-bit C compiler; instructions on - compiling it manually are available further down - - -********************* -*** What you need *** -********************* - - -To use DUMB, you need a 32-bit C compiler (GCC and MSVC are fine). If you -have Allegro, DUMB can integrate with its audio streams and datafiles, making -your life easier. If you do not wish to use Allegro, you will have to do some -work to get music playing back. The 'dumbplay' example program requires -Allegro. - - Allegro - http://alleg.sf.net/ - - -********************************************** -*** How to set DUMB up with DJGPP or MinGW *** -********************************************** - - -You should have got the .zip version. If for some reason you got the .tar.gz -version instead, you may have to convert make/config.bat to DOS text file -format. WinZip does this automatically by default. Otherwise, loading it into -MS EDIT and saving it again should do the trick (but do not do this to the -Makefiles as it destroys tabs). You will have to do the same for any files -you want to view in Windows Notepad. If you have problems, just go and -download the .zip instead. - -Make sure you preserved the directory structure when you extracted DUMB from -the archive. Most unzipping programs will do this by default, but pkunzip -requires you to pass -d. If not, please delete DUMB and extract it again -properly. - -If you are using Windows, open an MS-DOS Prompt or a Windows Command Line. -Change to the directory into which you unzipped DUMB. - -If you are using MinGW (and you haven't renamed 'mingw32-make'), type: - - mingw32-make - -Otherwise, type the following: - - make - -DUMB will ask you whether you wish to compile for DJGPP or MinGW. Then it -will ask you whether you want support for Allegro. (You have to have made and -installed Allegro's optimised library for this to work.) Finally, it will -compile optimised and debugging builds of DUMB, along with the example -programs. When it has finished, run one of the following to install the -libraries: - - make install - mingw32-make install - -All done! If you ever need the configuration again (e.g. if you compiled for -DJGPP before and you want to compile for MinGW now), run one of the -following: - - make config - mingw32-make config - -See the comments in the Makefile for other targets. - -Note: the Makefile will only work properly if you have COMSPEC or ComSpec set -to point to command.com or cmd.exe. If you set it to point to a Unix-style -shell, the Makefile won't work. - -Please let me know if you have any trouble. - -As an alternative, MSYS users may attempt to use the configure script, -available in dumb-0.9.3-autotools.tar.gz. This has been found to work without -Allegro, and is untested with Allegro. I should appreciate feedback from -anyone else who tries this. I do not recommend its use, partly because it -creates dynamically linked libraries and I don't know how to stop it from -doing that (see the section on compiling DUMB manually), and partly because -autotools are plain evil. - -Scroll down for information on the example programs. Refer to docs/howto.txt -when you are ready to start programming with DUMB.

If not, please delete DUMB and extract it again -properly. - -DUMB comes with a workspace Microsoft Visual C++ 6, containing projects for -the DUMB core, the Allegro interface library and each of the examples. The -first thing you might want to do is load the workspace up and have a look -around. You will find it in the dumb\vc6 directory under the name dumb.dsw. -Note that the aldumb and dumbplay projects require Allegro, so they won't -work if you don't have Allegro. Nevertheless, dumbplay is the best-commented -of the examples, so do have a look. - -When you are ready to add DUMB to your project, follow these instructions: - -1. Open your project in VC++. -2. Select Project|Insert Project into Workspace... -3. Navigate to the dumb\vc6\dumb directory and select dumb.dsp. - Alternatively, if you know that you are statically linking with a library - that uses the statically linked multithreaded runtime (/MT), you may wish - to select dumb_static.dsp in the dumb_static subdirectory instead. -4. Select Build|Set Active Configuration..., and reselect one of your - project's configurations. -5. Select Project|Dependencies... and ensure your project is dependent on - DUMB. -6. Select Project|Settings..., Settings for: All Configurations, C/C++ tab, - Preprocessor category. Add the DUMB include directory to the Additional - Include Directories box. -7. Ensure that for all the projects in the workspace (or more likely just all - the projects in a particular dependency chain) the run-time libraries are - the same. That's in Project|Settings, C/C++ tab, Code generation category, - Use run-time library dropdown. The settings for Release and Debug are - separate, so you'll have to change them one at a time. Exactly which run- - time library you use will depend on what you need; it doesn't appear that - DUMB has any particular requirements, so set it to whatever you're using - now.

If for some reason you got the .zip -version instead, you may have to strip all characters with ASCII code 13 from -some of the text files. If you have problems, just go and download the -.tar.gz instead. - -You have two options. There is a Makefile which should cope with most -systems. The first option is to use this default Makefile, and the procedure -is explained below. The second option is to download -dumb-0.9.3-autotools.tar.gz, extract it over the installation, run -./configure and use the generated Makefile. Users who choose to do this are -left to their own devices but advised to read the information at the end of -this section. I strongly recommend the first option. - -If you are not using the configure script, the procedure is as follows. - -First, run the following command as a normal user: - - make - -You will be asked whether you want Allegro support. Then, unless you are on -BeOS, you will be asked where you'd like DUMB to install its headers, -libraries and examples (which will go in the include/, lib/ and bin/ -subdirectories of the prefix you specify). BeOS has fixed locations for these -files. You may use shell variables here, e.g. $HOME or ${HOME}, but ~ will -not work. Once you have specified these pieces of information, the optimised -and debugging builds of DUMB will be compiled, along with the examples. When -it has finished, you can install them with: - - make install - -You may need to be root for this to work.

See the section -below on building DUMB manually for why I recommend linking DUMB statically. -However, if you choose to use the configure script, note the following. - -The default Makefile is a copy of Makefile.rdy (short for 'ready'), and it -must exist with the name Makefile.rdy in order to work.

They -are used for volume and note pitch calculations, and they are used when -initialising the filter algorithm for given cut-off and resonance values. -Please let me know if this is a problem for you. If there is enough demand, I -may be able to eliminate one or both of these cases. - -All of the library source code may be found in the src/ subdirectory. There -are headers in the include/ subdirectory, and src/helpers/resample.c also -#includes some .inc files in its own directory. - -There are four subdirectories under src/. For projects not using Allegro, you -will need all the files in src/core/, src/helpers/ and src/it/. If you are -using Allegro, you will want the src/allegro/ subdirectory too. For -consistency with the other build systems, the contents of src/allegro/ should -be compiled into a separate library. - -I recommend static-linking DUMB, since the version information is done via -macros and the API has a tendency to change. If you static-link, then once -your program is in binary form, you can be sure that changes to the installed -version of DUMB won't cause it to malfuction. It is my fault that the API has -been so unstable. Sorry! - -Compile each .c file separately. As mentioned above, you will need to specify -two places to look for #include files: the include/ directory and the source -file's own directory. You will also need to define the symbol -DUMB_DECLARE_DEPRECATED on the command line. - -Do not compile the .inc files separately. - -You may need to edit dumb.h and add your own definition for LONG_LONG. It -should be a 64-bit integer. If you do this, please see if you can add a check -for your compiler so that it still works with other compilers. - -DUMB has two build modes. If you define the symbol DEBUGMODE, some checks for -programmer error will be incorporated into the library. Otherwise it will be -built without any such checks. (DUMB will however always thoroughly check the -validity of files it is loading. If you ever find a module file that crashes -DUMB, please let me know!) - -I recommend building two versions of the library, one with DEBUGMODE defined -and debugging information included, and the other with compiler optimisation -enabled. If you can install DUMB system-wide so that your projects, and other -people's, can simply #include or and link with libraries -by simple name with no path, then that is ideal. - -If you successfully port DUMB to a new platform, please let me know! - - -**************************** -*** The example programs *** -**************************** - - -Three example programs are provided. On DOS and Windows, you can find them in -the examples subdirectory. On other systems they will be installed system- -wide. - -dumbplay - This program will only be built if you have Allegro. Pass it the filename - of an IT, XM, S3M or MOD file, and it will play it. It's not a polished - player with real-time threading or anything - so don't complain about it - stuttering while you use other programs - but it does show DUMB's fidelity - nicely. You can control the playback quality by editing dumb.ini, which - must be in the current working directory. (This is a flaw for systems - where the program is installed system-wide, but it is non-fatal.) Have a - look at the examples/dumb.ini file for further information. - -dumbout - This program does not need Allegro. You can use it to stream an IT, XM, - S3M or MOD file to raw PCM. This can be used as input to an encoder like - oggenc (with appropriate command-line options), or it can be sent to a - .pcm file which can be read by any respectable waveform editor. This - program is also convenient for timing DUMB. Compare the time it takes to - render a module with the module's playing time! dumbout doesn't try to - read any configuration file; the options are set on the command line. - -dumb2wav - This program is much the same as dumbout, but it writes a .wav file with - the appropriate header.

Welcome to a long-awaited-or-probably-just-given-up-on-by-everybody -release! New to this release are lower memory usage, faster mixing loops, -loading of text fields in the module files, and faster load functions for -projects that don't need to seek within the module or know its length. -Additionally, Chad Austin has contributed a dumb2wav tool for converting -modules to .wav files and updated the Visual Studio 6 project files to -compile all the examples as well as the library. Users of Unix-like systems -will be pleased to know that on Chad's suggestion I have made the build -system cope with variables such as $HOME or ${HOME} in the prefix. - -Chad has also contributed an Autotools build system, but neither of us -recommends its use. The Autotools are an evil black box, we haven't quite -managed to get it right, and goodness help you if it happens not to work for -you. The files are available in a separate download if you absolutely need -them. Notice that that download is almost twice as large as the rest of DUMB! - -Maybe we'll do SCons next time. - -Thanks to Chad for all his work. Chad is the author of Audiere, a portable -sound library which has started using DUMB for its module playback! Wahoo! - - http://audiere.sf.net/ - -There are three main optimisations that went into the mixing loops. - -First, I downloaded ModPlugXMMS and had a peek at the mixing code, which is -Public Domain. It uses look-up tables for the cubic mixing. I pinched the -idea, and that sped DUMB's cubic (best quality) resamplers up by a factor of -two or three. - -Secondly, the samples loaded from the file are now kept in 8-bit or 16-bit -format, whereas previously they were being converted to 24-bit-in-32-bit on -loading. This means the samples occupy a half or a quarter of the memory they -used to occupy. It also had the side-effect of speeding up the mixing loops, -but it meant I had to duplicate the resampling code. (It is all done with -macros in the source code, but it becomes two copies on the binary level.) - -Secondly, stereo samples and stereo mixing buffers are now kept in -interleaved format, where previously the two channels were done separately to -keep the code simpler. This change has made the library quite a bit bigger, -but has made the code run almost twice as fast for stereo output (tested for -modules whose samples are mostly mono)! - -DUMB is now as fast as ModPlugXMMS on my system. - -Some people have also commented that DUMB seems to take a long time loading -files. This is because immediately upon loading the file it runs the playback -engine over it up as far as the point of first loop, taking snapshots at 30- -second intervals to be used as references for fast seeking and finally -storing the playback time. Of course, most games don't need this. You can now -skip it by calling the _quick versions of the dumb_load_*(), dumb_read_*() or -dumb_register_dat_*() functions. Should you need the data later, you can call -dumb_it_do_initial_runthrough() to calculate it. Please note that this cannot -currently be done safely from a concurrent thread while the music is playing. - -As mentioned, DUMB loads the text fields in module files now. You can -retrieve the song title with duh_get_tag(). Sample names and file names and -instrument names and filenames, and the song message for IT files, are -available with a call to duh_get_it_sigdata() and various dumb_it_sd_*() -functions. Please note that text fields added as extensions by ModPlug -Tracker are not supported. - -DUMB's timing is ever so slightly more accurate. This is hardly noticeable, -but it has meant that the length computed will increase very slightly. - -There are many small playback fixes in this release: - -* The Lxx effect in XM files (set envelope position) is now supported. - -* Pattern looping is now correct for XM files. Bizarrely, an ordinary pattern - loop whose start point isn't the first row seems to cause the next pattern - to start at the row corresponding to the loop start point. That must have - been a headache for people creating XM files! Nevertheless, DUMB now - emulates this behaviour. If you have an XM file that was written in a - tracker other than Fast Tracker II and breaks in DUMB, you can get around - it by putting a D00 effect (break to row 0) right at the end of the pattern - containing the loop. - -* XM pattern looping can be infinite. DUMB should detect this and call the - loop callback when it happens. Specifically, it has a loop counter for each - channel, so each time it sets or decrements that counter, it remembers the - loop end point for that channel. When the loop terminates, the loop end - point is reset to 0. If the loop end point ever decreases during a loop, - the loop callback is called. If anyone manages to get around this check and - prevent DUMB from calling the callback, please let me know and send me an - illustrative XM file! - -* For IT files, notes are now removed from channels if they have faded out, - even if they are still in the foreground. After this has happened, a row - with a note and Gxx (tone portamento) specified will cause a new note to - start playing, which is what Impulse Tracker does in this scenario. - (Normally, Gxx prevents the new note from playing and instead causes the - old note to start sliding towards the new note.) - -* If a tone portamento command occurred when no note was playing, the effect - value wasn't stored. This has been fixed. Thanks to Maim from #trax on - EFnet for discovering this bug. - -* DUMB now treats the parameter to the undocumented XM key off effect Kxx as - a delay, consistent with Fast Tracker II's behaviour. It has also been made - not to clear the note, so a subsequent volume command will restore it, as - in Fast Tracker II. - -* DUMB used to process the first row when you created the - DUMB_IT_SIGRENDERER. This happened before you had a chance to install any - callbacks. If an F00 effect occurred on the first row, the music would stop - immediately and the xm_speed_zero callback would be called if it were - present. Unfortunately, it wasn't present, and the algorithm for - calculating the length subsequently went into an endless loop while waiting - for it. Worse still, the same algorithm accumulated data for fast seeking, - and never stopped, so it pretty quickly consumed all the resources. DUMB - will now not process the first row until you first request some samples, - provided you pass zero for pos. Of course, any MOD or XM file with F00 in - the very first row won't do much anyway, but such files won't crash the - library now. - -* There was a subtle bug that affected a few XM files. For instruments with - no associated samples, the array mapping notes to samples is uninitialised. - This became a problem if such instruments were then used, which does happen - sometimes. On many systems, memory is initialised to zero when first given - to a program (for security reasons), so the problem didn't come up most of - the time. However, on platforms like DOS where memory isn't initialised, or - in programs that reuse memory later on (this includes the XMMS plug-in with - which I discovered the bug), a rogue note would occasionally play. This has - now been fixed. - -* DUMB's envelope handling for IT files was subtly wrong. Upon note off, it - stopped obeying the sustain loop points one tick too early. Notes were - often shorter than they should have been, and in pathological cases a whole - extra iteration of the sustain loop section might have been skipped. The - envelope code has now been rewritten. Thanks go to Allefant for Valgrinding - the new code! - -Finally, there were two build problems in the last version, which were fixed -in the download marked with -fixed. They are of course correct in this -version. For the record: - -* The make/config.bat file, responsible for generating make/config.txt, wrote - a crucial line to the wrong place, causing it to be left out of the file. - As a result, the makefile would fail to install everything for Allegro - users, and enter infinite recursion for other users. This applied to people - using DJGPP and MinGW. - -* DUMB's Makefile was supposed to install the example programs on Unix-based - platforms, but it wasn't doing. The fix was to edit Makefile and change the - one occurrence of $COMSPEC to $(COMSPEC). - -That's it! I hope you enjoy this long-awaited-or-probably-just-given-up-on- -by-everybody release of DUMB! - - -****************************************** -*** DUMB v0.9.2, released 2 April 2003 *** -****************************************** - -Yes, there really has been a release. This is not a day-late April fools' -joke. - -DUMB's full name has changed! The old "Dedicated Universal Music -Bastardisation" was rather silly, and not much more than a forced attempt at -finding words beginning with D, U, M and B. I spent weeks and weeks browsing -dictionaries and hopelessly asking others for bright ideas, until the -brilliant Chris "Kitty Cat" Robinson came up with "Dynamic". I decided to -keep the U as Universal, since a DUH struct can hold digital music in any -format. Now all that remained was the B, but it didn't take me long to come -up with Bibliotheque, which, despite looking French, is indeed considered an -English word by Oxford English Dictionary Online, to which my university has -a subscription. So there you have it - the name now makes sense. - -The two most significant additions to the project would have to be the new -thread safety (with an important restriction, detailed in docs/dumb.txt), and -the new build system. The silly 'makeall' and 'makecore' scripts are gone. If -you are a GCC user, all you need do now is run 'make' and 'make install', as -for other projects. You don't even have to run a 'fix' script any more! There -are some caveats, which are covered in readme.txt. If you use Microsoft -Visual C++ 6, you no longer need to obtain GCC and GNU Make - there is a -project file just for you. - -Huge thanks go to Steve Terry for testing on Windows XP - about five times - -and to lillo for testing on BeOS and Mac OS X. Thanks also to X-G for testing -on a Windows system that has consistently posed problems for DUMB's old -makefiles. - -There was a bug whereby al_poll_duh() would sometimes cause the music to -resume playing if you called it after al_pause_duh(). Whether this was DUMB's -fault for misusing Allegro's API, or a bug in Allegro, is unclear, but this -release makes it work. - -In one of my projects, I found that my AL_DUH_PLAYER stopped playing when -there were lots of other sound effects. In order to fix this, I programmed -DUMB to set the priority of the stream's voice to 255, the maximum. I also -added al_duh_set_priority(), so you can set the priority yourself if you need -to. - -The resampling code has undergone a transformation. The bad news is that the -linear average code is no longer in use. The good news is that where DUMB's -resamplers used to require three extra samples' worth of memory to be -allocated and initialised, it now copes with just the sample data. And it -does a very good job at bouncing off loop points and otherwise hurtling -around the sample. The resampling code is considerably more complicated, but -the code that uses the resamplers is considerably simpler - and if you -noticed a slight click in some bidirectionally looping samples, you'll be -pleased to know that that click is gone! - -I have also devoted some effort to optimisation. It seemed hopeless for a -while, but then I actually figured out a way of making it faster AND more -accurate at the same time! DUMB is now quite a bit faster than it was, and it -mixes not with 16-bit precision, but with 24-bit precision. (It used 32-bit -integers all along, but the difference is that it now makes use of 256 times -as much of the integer's range.) - -There have been the usual improvements to playback. The last release occurred -rather too soon after I had fixed the XM effect memories; EAx and EBx, fine -volume ramps, had been neglected. These are now handled properly. - -In previous versions of DUMB, muted channels in IT were actually played with -surround sound panning (where the right-hand channel is inverted). This has -been fixed, so muted channels will really be muted now. - -There were also some subtle problems with the way DUMB handled New Note -Actions for IT files. It turned out that, in all releases of DUMB so far, -pitch, filter and panning envelopes and sample vibrato were not being -processed for any note that was forced into the background by a new note on -the same channel! This only affected IT files. Not only has this been fixed, -but envelope interpolation is much more accurate. Long trailing envelope- -driven fade-outs sound a lot better now! - -Since panning and filter envelopes are more precise, extra fields have been -added to the DUMB_IT_CHANNEL_STATE struct, used by -dumb_it_sr_get_channel_state(). These fields hold the 'decimal' parts of the -pan and filter cut-off. See dumb.txt for details. - -Mxx (set channel volume) now correctly only modifies the last note played on -the channel, not any previous notes that have been forced into the background -by New Note Actions, and filter effect processing is now closer to what -Impulse Tracker does. - -The XM loader was slightly flawed and could crash on files containing samples -with out-of-range loop points. One such file was given to me. This has been -fixed. - -Finally, the legal stuff. Julien Cugniere has been added to the list of -copyright owners. He deserves it, for all the work he did on the XM support! -And the licence has been changed. You are no longer required to include a -link to DUMB in a project that uses DUMB; the reasons for this relaxation are -explained in licence.txt. However, the request is still there ... - -As usual, enjoy! - - -********************************************** -*** DUMB v0.9.1, released 19 December 2002 *** -********************************************** - -Hi again! Lots to say this time, so I shall cut right to the chase. - -DUMB now supports Impulse Tracker's low-pass resonant filters! Huge thanks go -to Jeffrey Lim, author of Impulse Tracker, for giving me what information he -still had regarding the algorithm; to cut a long story short, modifying -ModPlug Tracker's source code (which is in the Public Domain) led to an -algorithm whose output matched Impulse Tracker's perfectly. - -Please note that ModPlug Tracker's filters as they stand do not match Impulse -Tracker's, and I have no interest in supporting ModPlug Tracker's variant -(especially not the integer rounding problems). Please see docs/modplug.txt, -new in this release, for details. - -Thanks also go to Fatso Huuskonen for motivating me to add filter support, -and providing me with several great IT files to test it with! - -The other important feature added for this release is click removal. Up until -now, DUMB has generated clicks when cutting notes, starting samples in the -middle, and so on. This version of DUMB will remove any such clicks. Note -that DUMB does not use volume ramps to accomplish this; the algorithm will -not take the bite out of the music! - -In other news, DUMB now supports sample vibrato for IT files, and instrument -vibrato for XM files. A slight bug in New Note Action handling for IT files -has been fixed; Note Fade will not break the sustain loops of the sample and -envelope, as it did before. Tremor handling (Ixy) had a strange bug in it, -which has been fixed. - -Support for XM files has been greatly enhanced. The XM envelope handling new -in the last release contained a huge bug, resulting in notes seeming not to -stop when they should; this has been fixed. Some XM files crashed DUMB, while -others failed to load; these problems have been solved. Effect memories now -work properly for XM and MOD files, to the best of my knowledge. Some other -differences between IT and XM have been accounted for, most notably the -Retrigger Note effects, Rxy and E9x. - -DUMB's sound quality and accuracy are not the only areas that have been -enhanced. The API has been expanded, at last. You can now detect when a -module loops, or make it play through just once. You can ask DUMB to inform -you every time it generates some samples; this is useful for visualisation. -For IT files, you can intercept the MIDI messages generated by Zxx macros, -enabling you to synchronise your game with the music to some extent. (There -is no such method for XM, S3M or MOD files yet; sorry. Also note that the -function will be called before you actually hear the sound; I cannot improve -this until DUMB has its own sound drivers, which won't be for a while.) You -can query the current order and row. Finally, operations like changing the -speed and tempo are now possible, and you can query the playback state on -each channel. - -Some parts of DUMB's API have been deprecated. Simple programs that use -Allegro will be unaffected, but if you get some compiler warnings or errors, -please review docs/deprec.txt. This file explains why those parts of the API -were deprecated, and tells you how to adapt your code; the changes you need -to make are straightforward. Sorry for the inconvenience. - -For various reasons, I have made DUMB's makefiles use different compiler -flags depending on your GCC version (unless you are using MSVC). There is no -elegant way of getting the makefiles to detect when GCC is upgraded. If you -upgrade GCC, you should execute 'make clean' in order to make DUMB detect the -GCC version again. Otherwise you may get some annoying error messages. (It is -wise to do this in any case, so that all the object files are built with the -same GCC version.) - -DUMB's example players have been unified into a single player called -'dumbplay'. The player has been enhanced to display messages when the music -loops, and when XM and MOD files freeze (effect F00; more information on this -in docs/howto.txt). - -Finally, as noted on DUMB's website, the release notes from the last release -were inaccurate. It has been verified that DUMBOGG v0.5 does still work with -that release, and still works with this release. The esoteric DUMBOGG v0.6 -has not been created yet, since DUMBOGG v0.5 still works. - -Please scroll down and read through the indented paragraphs in the notes for -the last release; they are relevant for this release too. - -That's all folks! Until next time. - - -******************************************* -*** DUMB v0.9, released 16 October 2002 *** -******************************************* - -MOD support is here! DUMB now supports all four of the common module formats. -As usual, there have also been some improvements to the way modules are -played back. Most notably, handling of tone portamento in IT files has been -improved a lot, and XM envelopes are now processed correctly. - -The other major change is that DUMB now does a dummy run through each module -on loading. It stores the playback state at thirty-second intervals. It stops -when the module first loops, and then stores the playback time. This results -in a slightly longer load time and a greater memory overhead, but seeking is -faster (to any point before the module first loops) and the length is -calculated! duh_get_length() will return this and is now documented in -docs/howto.txt and docs/dumb.txt. - -DUMB's build process has been changed to use 'mingw' wherever it used -'mingw32' before; some directories have been renamed, and the 'fix' command -you had to run for MinGW has been changed from 'fix mingw32' to 'fix mingw'. - -Last time, I directed you to scroll down and read the notes from a past -release, but ignore this point, and that point applies to something else, and -so on. Did anyone do so? Well, if you're reading this at all, you probably -did. Nevertheless, this time I shall be much less confusing and restate any -relevant information. So the least you can do is read it! - -- If your program ever aborts with exit code 37 while loading an IT file, - PLEASE LET ME KNOW! The IT file in question has a stereo compressed sample - in it, and the format is unspecified for this case (Impulse Tracker itself - doesn't use stereo samples at all). I will need the IT file in question, - and any information you can give me about how the IT file was created (e.g. - what program). (If you don't get to see an exit code, let me know anyway.) - -- If your program ever outputs a line resembling "Inst 01 Env: 0,64 8,32 - 15,48" to stderr while loading an IT file, PLEASE LET ME KNOW! You have an - old IT file (saved by an Impulse Tracker version older than 2.00), and - support for such files is STILL untested. - -- Not all parts of DUMB's API are documented yet. You will find some - functions in dumb.h which are not listed in docs/dumb.txt; the reason is - that these functions still need work and will probably change. If you - really, really want to use them, talk to me first (IRC EFnet #dumb is a - good place for this; see readme.txt for details on using IRC). I intend to - finalise and document the whole of DUMB's API for Version 1.0. - -There have been some changes to the naming conventions in DUMB's undocumented -API. DUMBOGG v0.5 will not work with this and subsequent releases of DUMB; -please upgrade to DUMBOGG v0.6. These changes should not break anything in -your own code, since you didn't use those parts of the API, did you ;) - -There is still a great deal of work to be done before DUMB's API can be -finalised, and thus it will be a while before DUMB v1.0 comes out. It should -be worth the wait. In the meantime, there will be 0.9.x releases with -additional functionality, improved playback, and possibly support for some -extra file formats. - -Finally I should like to offer an apology; there is a strong possibility that -some of DUMB's official API will change in the near future. There will not be -any drastic changes, and the corresponding changes to your source code will -be simple enough. If I didn't make these changes, DUMB's API would start to -become limited, or messy, or both, so it's for the better. I apologise in -advance for this. - -Now scroll down and read the notes for the first r... oh wait, we already did -that. I guess that's it then. You can stop reading now. - -Right after you've read this. - -And this. - -Off you go. - -Bye. - - -******************************************** -*** DUMB v0.8.1, released 11 August 2002 *** -******************************************** - -This is a minor release that fixes a few bugs. One of these bugs, however, -was pretty serious. dumb_register_dat_xm() was never coded! It was prototyped -in aldumb.h, so code would compile, but there would be an unresolved symbol -at the linking stage. This has been fixed. - -Platforms other than Unix did not have a working 'make veryclean' target; -this has been fixed. In addition, the makefiles now use 'xcopy' instead of -'copy', since on some systems GNU Make seems to have trouble calling commands -built in to the shell. - -Contrary to the errata that was on the DUMB website, the makeall.sh and -makecore.sh scripts actually DID install in /usr. This has now been -corrected, and regardless of whether you use these scripts or call make -directly, the files will now be installed to /usr/local by default. - -The XM loader used to treat stereo samples as mono samples with the data for -the right channel positioned after the data for the left channel. This -generally resulted in an unwanted echo effect. This has been fixed. - -When playing XM files, specifying an invalid instrument would cause an old -note on that channel to come back (roughly speaking). Fast Tracker 2 does not -exhibit this behaviour. This has been fixed. - -The GCC makefiles used -mpentium, which is deprecated in gcc 3.x. This was -generating warnings, and has now been fixed. - -In XM files, the length of a sample is stored in bytes. DUMB was assuming -that the length of a 16-bit sample would be even. I had two XM files where -this was not the case, and DUMB was unable to load them. This has been fixed. - -In order to accommodate the extra part of the version number, -DUMB_REVISION_VERSION has been added. DUMB_VERSION has also been added in -order to facilitate checking if the version of DUMB installed is sufficient. -See docs/dumb.txt for details. - -As a last-minute fix, the XM "Break to row" effect is now loaded properly. It -was necessary to convert from binary-coded decimal to hexadecimal (those who -have experience with Fast Tracker 2 will know what I mean). In short, this -means the effect will now work properly when breaking to row 10 or greater. - -DUMB v0.8 had faulty release date constants; DUMB_MONTH and DUMB_DAY were -swapped! For this reason, DUMB_DATE should not be compared against any date -in 2002. This note has been added to docs/dumb.txt and also to dumb.h. - -Please scroll to the end and read the release notes for the first version, -DUMB v0.7. Most of them apply equally to this release. However, the -non-portable code was rewritten for DUMB v0.8, so that point does not apply. -The point about length not being calculated also applies to XM files. - -Enjoy :) - - -**************************************** -*** DUMB v0.8, released 14 June 2002 *** -**************************************** - -Welcome to the second release of DUMB! - -In addition to these notes, please read below the release notes for the -previous version, DUMB v0.7. Most of them apply equally to this release. -However, the non-portable code has been rewritten; DUMB should now port to -big-endian platforms. - -The main improvement in this release of DUMB is the support for XM files. -Enormous thanks go to Julien Cugniere for working on this while I had to -revise for my exams! - -There was a mistake in the makefiles in the last release. The debugging -Allegro interface library was mistakenly named libaldmbd.a instead of -libaldmd.a, meaning you had to compile with -laldmbd, contrary to what the -docs said. Apologies to everyone who lost sleep trying to work out what was -wrong! The reason for using libaldmd.a is to maintain compatibility with -plain DOS, where filenames are limited to eight characters (plus a three- -letter extension). The makefiles have now been changed to match the -information in the docs, so you may have to alter your project files -accordingly. - -The example programs were faulty, and crashed on Windows if they were unable -to load the file. It was also difficult to work out how to exit them (you had -to click the taskbar button that didn't have a window, then press a key). -They have been improved in both these respects. - -I have now added a docs/faq.txt file (Frequently Asked Questions), which is -based on problems and misconceptions people have had with the first release. -Please refer to it before contacting me with problems. - -Thanks to networm for touching up the Unix makefile and writing the -instructions on using it. - -Incidentally, today (Friday 14 June) is the Robinson College May Ball at -Cambridge Uni. God knows why it's called a May Ball if it's in June. I'm not -going myself (72 GBP, and I'd have to wear a suit, ugh), but with all the -noise outside I shall enjoy pumping up the speakers tonight! - - -**************************************** -*** DUMB v0.7, released 2 March 2002 *** -**************************************** - -This is the first release of DUMB, and parts of the library are not -crystallised. Don't let this put you off! Provided you don't try to use any -features that aren't documented in docs/dumb.txt, the library should be rock -solid and you should be able to upgrade more or less without problems. - -Here are some notes on this release: - -- There is some non-portable code in this release of DUMB. It is likely that - the library will fail to load IT files with compressed samples on - big-endian machines such as the Apple Macintosh. - -- If your program ever aborts with exit code 37 while loading an IT file, - PLEASE LET ME KNOW!

- -Architecture ------------- -The library is essentially a bunch of independent game music file -emulators unified with a common interface. - -Gme_File and Music_Emu provide a common interface to the emulators. The -virtual functions are protected rather than public to allow pre- and -post-processing of arguments and data in one place. This allows the -emulator classes to assume that everything is set up properly when -starting a track and playing samples. - -All file input is done with the Data_Reader interface. Many derived -classes are present, for the usual disk-based file and block of memory, -to specialized adaptors for things like reading a subset of data or -combining a block of memory with a Data_Reader to the remaining data. -This makes the library much more flexible with regard to the source of -game music file data. I still added a specialized load_mem() function to -have the emulator keep a pointer to data already read in memory, for -those formats whose files can be absolutely huge (GYM, some VGMs). This -is important if for some reason the caller must load the data ahead of -time, but doesn't want the emulator needlessly making a copy. - -Since silence checking and fading are relatively complex, they are kept -separate from basic file loading and track information, which are -handled in the base class Gme_File. My original intent was to use -Gme_File as the common base class for full emulators and track -information-only readers, but implementing the C interface was much -simpler if both derived from Music_Emu. User C++ code can still benefit -from static checking by using Gme_File where only track information will -be accessed. - -Each emulator generally has three components: main emulator, CPU -emulator, and sound chip emulator(s). Each component has minimal -coupling, so use in a full emulator or stand alone is fairly easy. This -modularity really helps reduce complexity. Blip_Buffer helps a lot with -simplifying the APU interfaces and implementation. - -The "classic" emulators derive from Classic_Emu, which handles -Blip_Buffer filling and multiple channels. It uses Multi_Buffer for -output, allowing you to derive a custom buffer that could output each -voice to a separate sound channel and do different processing on each. -At some point I'm going to implement a better Effects_Buffer that allows -individual control of every channel. - -In implementing the C interface, I wanted a way to specify an emulator -type that didn't require linking in all the emulators. For each emulator -type there is a global object with pointers to functions to create the -emulator or a track information reader. The emulator type is thus a -pointer to this, which conveniently allows for a NULL value. The user -referencing this emulator type object is what ultimately links the -emulator in (unless new Foo_Emu is used in C++, of course). This type -also serves as a useful substitute for RTTI on older C++ compilers. - -Addendum: I have since added gme_type_list(), which causes all listed -emulators to be linked in. To avoid this, I make the list itself -editable in blargg_config.h. Having a built-in list allows -gme_load_file() to take a path and give back an emulator with the file -loaded, which is extremely useful for new users. - - -Interface conventions ----------------------- -If a function retains a pointer to or replaces the value of an object -passed, it takes a pointer so that it will be clear in the caller's -source code that care is required. - -Multi-word names have an underscore '_' separator between individual -words. - -Functions are named with lowercase words. Functions which perform an -action with side-effects are named with a verb phrase (i.e. load, move, -run). Functions which return the value of a piece of state are named -using a noun phrase (i.e. loaded, moved, running). - -Classes are named with capitalized words. Only the first letter of an -acronym is capitalized. Class names are nouns, sometimes suggestive of -what they do (i.e. File_Scanner). - -Structure, enumeration, and typedefs to these and built-in types are -named using lowercase words with a _t suffix. - -Macros are named with all-uppercase words. - -Internal names which can't be hidden due to technical reasons have an -underscore '_' suffix. - - -Managing Complexity -------------------- -Complexity has been a factor in most library decisions. Many features -have been passed by due to the complexity they would add. Once -complexity goes past a certain level, it mentally grasping the library -in its entirety, at which point more defects will occur and be hard to -find. - -I chose 16-bit signed samples because it seems to be the most common -format. Supporting multiple formats would add too much complexity to be -worth it. Other formats can be obtained via conversion. - -I've kept interfaces fairly lean, leaving many possible features -untapped but easy to add if necessary. For example the classic emulators -could have volume and frequency equalization adjusted separately for -each channel, since they each have an associated Blip_Synth. - -Source files of 400 lines or less seem to be the best size to limit -complexity. In a few cases there is no reasonable way to split longer -files, or there is benefit from having the source together in one file. - - -Preventing Bugs ---------------- -I've done many things to reduce the opportunity for defects. A general -principle is to write code so that defects will be as visible as -possible. I've used several techniques to achieve this. - -I put assertions at key points where defects seem likely or where -corruption due to a defect is likely to be visible. I've also put -assertions where violations of the interface are likely. In emulators -where I am unsure of exact hardware operation in a particular case, I -output a debug-only message noting that this has occurred; many times I -haven't implemented a hardware feature because nothing uses it. I've -made code brittle where there is no clear reason flexibility; code -written to handle every possibility sacrifices quality and reliability -to handle vaguely defined situations. - - -Flexibility through indirection -------------------------------- -I've tried to allow the most flexibility of modules by using indirection -to allow extension by the user. This keeps each module simpler and more -focused on its unique task. - -The classic emulators use Multi_Buffer, which potentially allows a -separate Blip_Buffer for each channel. This keeps emulators free of -typical code to allow output in mono, stereo, panning, etc. - -All emulators use a reader object to access file data, allowing it to be -stored in a regular file, compressed archive, memory, or generated -on-the-fly. Again, the library can be kept free of the particulars of -file access and changes required to support new formats. - - -Emulators in general --------------------- -When I wrote the first NES sound emulator, I stored most of the state in -an emulator-specific format, with significant redundancy. In the -register write function I decoded everything into named variables. I -became tired of the verbosity and wanted to more closely model the -hardware, so I moved to a style of storing the last written value to -each register, along with as little other state as possible, mostly the -internal hardware registers. While this involves slightly more -recalculation, in most cases the emulation code is of comparable size. -It also makes state save/restore (for use in a full emulator) much -simpler. Finally, it makes debugging easier since the hardware registers -used in emulation are obvious. - - -CPU Cores ---------- -I've spent lots of time coming up with techniques to optimize the CPU -cores. Some of the most important: execute multiple instructions during -an emulation call, keep state in local variables to allow register -assignment, optimize state representation for most common instructions, -defer status flag calculation until actually needed, read program code -directly without a call to the memory read function, always pre-fetch -the operand byte before decoding instruction, and emulate instructions -using common blocks of code. - -I've successfully used Nes_Cpu in a fairly complete NES emulator, and -I'd like to make all the CPU emulators suitable for use in emulators. It -seems a waste for them to be used only for the small amount of emulation -necessary for game music files. - -I debugged the CPU cores by writing a test shell that ran them in -parallel with other CPU cores and compared all memory accesses and -processor states at each step. This provided good value at little cost. - -The CPU mapping page size is adjustable to allow the best tradeoff -between memory/cache usage and handler granularity. The interface allows -code to be somewhat independent of the page size. - -I optimize program memory accesses to direct reads rather than calls to -the memory read function. My assumption is that it would be difficult to -get useful code out of hardware I/O addresses, so no software will -intentionally execute out of I/O space. Since the page size can be -changed easily, most program memory mapping schemes can be accommodated. -This greatly reduces memory access function calls. - diff --git a/libraries/game-music-emu/gme.txt b/libraries/game-music-emu/gme.txt deleted file mode 100644 index 5a7d2f560..000000000 --- a/libraries/game-music-emu/gme.txt +++ /dev/null @@ -1,376 +0,0 @@ -Game_Music_Emu 0.6.2 --------------------- -Author : Shay Green -Maintainer : Michael Pyne -Website : https://bitbucket.org/mpyne/game-music-emu/ -Source : https://bitbucket.org/mpyne/game-music-emu/ -License : GNU Lesser General Public License (LGPL), see LICENSE.txt - -Contents --------- -* Overview -* Error handling -* Emulator types -* M3U playlist support -* Information fields -* Track length -* Loading file data -* Sound parameters -* VGM/GYM YM2413 & YM2612 FM sound -* Modular construction -* Obscure features -* Solving problems -* Thanks - - -Overview --------- -This library can open game music files, play tracks, and read game and -track information tags. To play a game music file, do the following: - -* Open the file with gme_open_file() -* Start a track with gme_start_track(); -* Generate samples as needed with gme_play() -* Play samples through speaker using your operating system -* Delete emulator when done with gme_delete() - -Your code must arrange for the generated samples to be played through -the computer's speaker using whatever method your operating system -requires. - -There are many additional features available; you can: - -* Determine of the type of a music file without opening it with -gme_identify_*() -* Load just the file's information tags with gme_info_only -* Load from a block of memory rather than a file with gme_load_data() -* Arrange for a fade-out at a particular time with gme_set_fade -* Find when a track has ended with gme_track_ended() -* Seek to a new time in the track with gme_seek() -* Load an extended m3u playlist with gme_load_m3u() -* Get a list of the voices (channels) and mute them individually with -gme_voice_names() and gme_mute_voice() -* Change the playback tempo without affecting pitch with gme_set_tempo() -* Adjust treble/bass equalization with gme_set_equalizer() -* Associate your own data with an emulator and later get it back with -gme_set_user_data() -* Register a function of yours to be called back when the emulator is -deleted with gme_set_user_cleanup() - -Refer to gme.h for a comprehensive summary of features. - - -Error handling --------------- -Functions which can fail have a return type of gme_err_t, which is a -pointer to an error string (const char*). If a function is successful it -returns NULL. Errors that you can easily avoid are checked with debug -assertions; gme_err_t return values are only used for genuine run-time -errors that can't be easily predicted in advance (out of memory, I/O -errors, incompatible file data). Your code should check all error -values. - -When loading a music file in the wrong emulator or trying to load a -non-music file, gme_wrong_file_type is returned. You can check for this -error in C++ like this: - - gme_err_t err = gme_open_file( path, &emu ); - if ( err == gme_wrong_file_type ) - ... - -To check for minor problems, call gme_warning() to get a string -describing the last warning. Your player should allow the user some way -of knowing when this is the case, since these minor errors could affect -playback. Without this information the user can't solve problems as -well. When playing a track, gme_warning() returns minor playback-related -problems (major playback problems end the track immediately and set the -warning string). - - -Emulator types --------------- -The library includes several game music emulators that each support a -different file type. Each is identified by a gme_type_t constant defined -in gme.h, for example gme_nsf_emu is for the NSF emulator. If you use -gme_open_file() or gme_open_data(), the library does the work of -determining the file type and creating an appropriate emulator. If you -want more control over this process, read on. - -There are two basic ways to identify a game music file's type: look at -its file extension, or read the header data. The library includes -functions to help with both methods. The first is preferable because it -is fast and the most common way to identify files. Sometimes the -extension is lost or wrong, so the header must be read. - -Use gme_identify_extension() to find the correct game music type based -on a filename. To identify a file based on its extension and header -contents, use gme_identify_file(). If you read the header data yourself, -use gme_identify_header(). - -If you want to remove support for some music types to reduce your -executable size, edit GME_TYPE_LIST in blargg_config.h. For example, to -support just NSF and GBS, use this: - - #define GME_TYPE_LIST \ - gme_nsf_type,\ - gme_gbs_type - - -M3U playlist support --------------------- -The library supports playlists in an extended m3u format with -gme_load_m3u() to give track names and times to multi-song formats: AY, -GBS, HES, KSS, NSF, NSFE, and SAP. Some aspects of the file format -itself is not well-defined so some m3u files won't work properly -(particularly those provided with KSS files). Only m3u files referencing -a single file are supported; your code must handle m3u files covering -more than one game music file, though it can use the built-in m3u -parsing provided by the library. - - -Information fields ------------------- -Support is provided for the various text fields and length information -in a file with gme_track_info(). If you just need track information for -a file (for example, building a playlist), use gme_new_info() in place -of gme_new_emu(), load the file normally, then you can access the track -count and info, but nothing else. - - M3U VGM GYM SPC SAP NSFE NSF AY GBS HES KSS - ------------------------------------------------------- -Track Count | * * * * * * * * * - | -System | * * * * * * * * * * - | -Game | * * * * * * * - | -Song | * * * * * * * - | -Author | * * * * * * * * - | -Copyright | * * * * * * * * - | -Comment | * * * * - | -Dumper | * * * * - | -Length | * * * * * * - | -Intro Length| * * * - | -Loop Length | * * * - -As listed above, the HES and KSS file formats don't include a track -count, and tracks are often scattered over the 0-255 range, so an m3u -playlist for these is a must. - -Unavailable text fields are set to an empty string and times to -1. Your -code should be prepared for any combination of available and unavailable -fields, as a particular music file might not use all of the supported -fields listed above. - -Currently text fields are truncated to 255 characters. Obscure fields of -some formats are not currently decoded; contact me if you want one -added. - - -Track length ------------- -The library leaves it up to you as to when to stop playing a track. You -can ask for available length information and then tell the library what -time it should start fading the track with gme_set_fade(). By default it -also continually checks for 6 or more seconds of silence to mark the end -of a track. Here is a reasonable algorithm you can use to decide how -long to play a track: - -* If the track length is > 0, use it -* If the loop length > 0, play for intro + loop * 2 -* Otherwise, default to 2.5 minutes (150000 msec) - -If you want to play a track longer than normal, be sure the loop length -isn't zero. See Music_Player.cpp around line 145 for example code. - -By default, the library skips silence at the beginning of a track. It -also continually checks for the end of a non-looping track by watching -for 6 seconds of unbroken silence. When doing this is scans *ahead* by -several seconds so it can report the end of the track after only one -second of silence has actually played. This feature can be disabled with -gme_ignore_silence(). - - -Loading file data ------------------ -The library allows file data to be loaded in many different ways. All -load functions return an error which you should check. The following -examples assume these variables: - - Music_Emu* emu; - gme_err_t error; - -If you're letting the library determine a file's type, you can use -either gme_open_file() or gme_open_data(): - - error = gme_open_file( pathname, &emu ); - error = gme_open_data( pointer, size, &emu ); - -If you're manually determining file type and using used gme_new_emu() to -create an emulator, you can use the following methods of loading: - -* From a block of memory: - - error = gme_load_data( emu, pointer, size ); - -* Have library call your function to read data: - - gme_err_t my_read( void* my_data, void* out, long count ) - { - // code that reads 'count' bytes into 'out' buffer - // and return 0 if no error - } - - error = gme_load_custom( emu, my_read, file_size, my_data ); - - -Sound parameters ----------------- -All emulators support an arbitrary output sampling rate. A rate of 44100 -Hz should work well on most systems. Since band-limited synthesis is -used, a sampling rate above 48000 Hz is not necessary and will actually -reduce sound quality and performance. - -All emulators also support adjustable gain, mainly for the purpose of -getting consistent volume between different music formats and avoiding -excessive modulation. The gain can only be set *before* setting the -emulator's sampling rate, so it's not useful as a general volume -control. The default gains of emulators are set so that they give -generally similar volumes, though some soundtracks are significantly -louder or quieter than normal. - -Some emulators support adjustable treble and bass frequency equalization -(AY, GBS, HES, KSS, NSF, NSFE, SAP, VGM) using set_equalizer(). -Parameters are specified using gme_equalizer_t eq = { treble_dB, -bass_freq }. Treble_dB sets the treble level (in dB), where 0.0 dB gives -normal treble; -200.0 dB is quite muffled, and 5.0 dB emphasizes treble -for an extra crisp sound. Bass_freq sets the frequency where bass -response starts to diminish; 15 Hz is normal, 0 Hz gives maximum bass, -and 15000 Hz removes all bass. For example, the following makes the -sound extra-crisp but lacking bass: - - gme_equalizer_t eq = { 5.0, 1000 }; - gme_set_equalizer( music_emu, &eq ); - -Each emulator's equalization defaults to approximate the particular -console's sound quality; this default can be determined by calling -equalizer() just after creating the emulator. The Music_Emu::tv_eq -profile gives sound as if coming from a TV speaker, and some emulators -include other profiles for different versions of the system. For -example, to use Famicom sound equalization with the NSF emulator, do the -following: - - music_emu->set_equalizer( Nsf_Emu::famicom_eq ); - - -VGM/GYM YM2413 & YM2612 FM sound --------------------------------- -The library plays Sega Genesis/Mega Drive music using a YM2612 FM sound -chip emulator based on the Gens project. Because this has some -inaccuracies, other YM2612 emulators can be used in its place by -re-implementing the interface in YM2612_Emu.h. Available on my website -is a modified version of MAME's YM2612 emulator, which sounds better in -some ways and whose author is still making improvements. - -VGM music files using the YM2413 FM sound chip are also supported, but a -YM2413 emulator isn't included with the library due to technical -reasons. I have put one of the available YM2413 emulators on my website -that can be used directly. - - -Modular construction --------------------- -The library is made of many fairly independent modules. If you're using -only one music file emulator, you can eliminate many of the library -sources from your program. Refer to the files list in readme.txt to get -a general idea of what can be removed, and be sure to edit GME_TYPE_LIST -(see "Emulator types" above). Post to the forum if you'd like me to put -together a smaller version for a particular use, as this only takes me a -few minutes to do. - -If you want to use one of the individual sound chip emulators (or CPU -cores) in your own console emulator, first check the libraries page on -my website since I have released several of them as stand alone -libraries with included documentation and examples on their use. If you -don't find it as a standalone library, contact me and I'll consider -separating it. - -The "classic" sound chips use my Blip_Buffer library, which greatly -simplifies their implementation and efficiently handles band-limited -synthesis. It is also available as a stand alone library with -documentation and many examples. - - -Obscure features ----------------- -The library's flexibility allows many possibilities. Contact me if you -want help implementing ideas or removing limitations. - -* Uses no global/static variables, allowing multiple instances of any -emulator. This is useful in a music player if you want to allow -simultaneous recording or scanning of other tracks while one is already -playing. This will also be useful if your platform disallows global -data. - -* Emulators that support a custom sound buffer can have *every* voice -routed to a different Blip_Buffer, allowing custom processing on each -voice. For example you could record a Game Boy track as a 4-channel -sound file. - -* Defining BLIP_BUFFER_FAST uses lower quality, less-multiply-intensive -synthesis on "classic" emulators, which might help on some really old -processors. This significantly lowers sound quality and prevents treble -equalization. Try this if your platform's processor isn't fast enough -for normal quality. Even on my ten-year-old 400 MHz Mac, this reduces -processor usage at most by about 0.6% (from 4% to 3.4%), hardly worth -the quality loss. - - -Solving problems ----------------- -If you're having problems, try the following: - -* If you're getting garbled sound, try this simple siren generator in -place of your call to play(). This will quickly tell whether the problem -is in the library or in your code. - - static void play_siren( long count, short* out ) - { - static double a, a2; - while ( count-- ) - *out++ = 0x2000 * sin( a += .1 + .05*sin( a2+=.00005 ) ); - } - -* Enable debugging support in your environment. This enables assertions -and other run-time checks. - -* Turn the compiler's optimizer is off. Sometimes an optimizer generates -bad code. - -* If multiple threads are being used, ensure that only one at a time is -accessing a given set of objects from the library. This library is not -in general thread-safe, though independent objects can be used in -separate threads. - -* If all else fails, see if the demos work. - - -Thanks ------- -Big thanks to Chris Moeller (kode54) for help with library testing and -feedback, for maintaining the Foobar2000 plugin foo_gep based on it, and -for original work on openspc++ that was used when developing Spc_Emu. -Brad Martin's excellent OpenSPC SNES DSP emulator worked well from the -start. Also thanks to Richard Bannister, Mahendra Tallur, Shazz, -nenolod, theHobbit, Johan Samuelsson, and nes6502 for testing, using, -and giving feedback for the library in their respective game music -players. More recently, Lucas Paul and Michael Pyne have helped nudge the -library into a public repository and get its interface more stable for use -in shared libraries. diff --git a/libraries/game-music-emu/gme/Ay_Apu.cpp b/libraries/game-music-emu/gme/Ay_Apu.cpp deleted file mode 100644 index d132c42f9..000000000 --- a/libraries/game-music-emu/gme/Ay_Apu.cpp +++ /dev/null @@ -1,395 +0,0 @@ -// Game_Music_Emu https://bitbucket.org/mpyne/game-music-emu/ - -#include "Ay_Apu.h" - -/* Copyright (C) 2006 Shay Green.

It also counts - as the successor of the GNU Library Public License, version 2, hence - the version number 2.1.] - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -Licenses are intended to guarantee your freedom to share and change -free software--to make sure the software is free for all its users. - - This license, the Lesser General Public License, applies to some -specially designated software packages--typically libraries--of the -Free Software Foundation and other authors who decide to use it. You -can use it too, but we suggest you first think carefully about whether -this license or the ordinary General Public License is the better -strategy to use in any particular case, based on the explanations below. - - When we speak of free software, we are referring to freedom of use, -not price. Our General Public Licenses are designed to make sure that -you have the freedom to distribute copies of free software (and charge -for this service if you wish); that you receive source code or can get -it if you want it; that you can change the software and use pieces of -it in new free programs; and that you are informed that you can do -these things. - - To protect your rights, we need to make restrictions that forbid -distributors to deny you these rights or to ask you to surrender these -rights. These restrictions translate to certain responsibilities for -you if you distribute copies of the library or if you modify it. - - For example, if you distribute copies of the library, whether gratis -or for a fee, you must give the recipients all the rights that we gave -you. You must make sure that they, too, receive or can get the source -code. If you link other code with the library, you must provide -complete object files to the recipients, so that they can relink them -with the library after making changes to the library and recompiling -it. And you must show them these terms so they know their rights. - - We protect your rights with a two-step method: (1) we copyright the -library, and (2) we offer you this license, which gives you legal -permission to copy, distribute and/or modify the library. - - To protect each distributor, we want to make it very clear that -there is no warranty for the free library. Also, if the library is -modified by someone else and passed on, the recipients should know -that what they have is not the original version, so that the original -author's reputation will not be affected by problems that might be -introduced by others. - - Finally, software patents pose a constant threat to the existence of -any free program. We wish to make sure that a company cannot -effectively restrict the users of a free program by obtaining a -restrictive license from a patent holder. Therefore, we insist that -any patent license obtained for a version of the library must be -consistent with the full freedom of use specified in this license. - - Most GNU software, including some libraries, is covered by the -ordinary GNU General Public License. This license, the GNU Lesser -General Public License, applies to certain designated libraries, and -is quite different from the ordinary General Public License. We use -this license for certain libraries in order to permit linking those -libraries into non-free programs. - - When a program is linked with a library, whether statically or using -a shared library, the combination of the two is legally speaking a -combined work, a derivative of the original library. The ordinary -General Public License therefore permits such linking only if the -entire combination fits its criteria of freedom. The Lesser General -Public License permits more lax criteria for linking other code with -the library. - - We call this license the "Lesser" General Public License because it -does Less to protect the user's freedom than the ordinary General -Public License. It also provides other free software developers Less -of an advantage over competing non-free programs. These disadvantages -are the reason we use the ordinary General Public License for many -libraries. However, the Lesser license provides advantages in certain -special circumstances. - - For example, on rare occasions, there may be a special need to -encourage the widest possible use of a certain library, so that it becomes -a de-facto standard. To achieve this, non-free programs must be -allowed to use the library. A more frequent case is that a free -library does the same job as widely used non-free libraries. In this -case, there is little to gain by limiting the free library to free -software only, so we use the Lesser General Public License. - - In other cases, permission to use a particular library in non-free -programs enables a greater number of people to use a large body of -free software. For example, permission to use the GNU C Library in -non-free programs enables many more people to use the whole GNU -operating system, as well as its variant, the GNU/Linux operating -system. - - Although the Lesser General Public License is Less protective of the -users' freedom, it does ensure that the user of a program that is -linked with the Library has the freedom and the wherewithal to run -that program using a modified version of the Library. - - The precise terms and conditions for copying, distribution and -modification follow. Pay close attention to the difference between a -"work based on the library" and a "work that uses the library". The -former contains code derived from the library, whereas the latter must -be combined with the library in order to run. - - GNU LESSER GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License Agreement applies to any software library or other -program which contains a notice placed by the copyright holder or -other authorized party saying it may be distributed under the terms of -this Lesser General Public License (also called "this License"). -Each licensee is addressed as "you". - - A "library" means a collection of software functions and/or data -prepared so as to be conveniently linked with application programs -(which use some of those functions and data) to form executables. - - The "Library", below, refers to any such software library or work -which has been distributed under these terms. A "work based on the -Library" means either the Library or any derivative work under -copyright law: that is to say, a work containing the Library or a -portion of it, either verbatim or with modifications and/or translated -straightforwardly into another language. (Hereinafter, translation is -included without limitation in the term "modification".) - - "Source code" for a work means the preferred form of the work for -making modifications to it. For a library, complete source code means -all the source code for all modules it contains, plus any associated -interface definition files, plus the scripts used to control compilation -and installation of the library. - - Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running a program using the Library is not restricted, and output from -such a program is covered only if its contents constitute a work based -on the Library (independent of the use of the Library in a tool for -writing it). Whether that is true depends on what the Library does -and what the program that uses the Library does. - - 1. You may copy and distribute verbatim copies of the Library's -complete source code as you receive it, in any medium, provided that -you conspicuously and appropriately publish on each copy an -appropriate copyright notice and disclaimer of warranty; keep intact -all the notices that refer to this License and to the absence of any -warranty; and distribute a copy of this License along with the -Library. - - You may charge a fee for the physical act of transferring a copy, -and you may at your option offer warranty protection in exchange for a -fee. - - 2. You may modify your copy or copies of the Library or any portion -of it, thus forming a work based on the Library, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) The modified work must itself be a software library. - - b) You must cause the files modified to carry prominent notices - stating that you changed the files and the date of any change. - - c) You must cause the whole of the work to be licensed at no - charge to all third parties under the terms of this License. - - d) If a facility in the modified Library refers to a function or a - table of data to be supplied by an application program that uses - the facility, other than as an argument passed when the facility - is invoked, then you must make a good faith effort to ensure that, - in the event an application does not supply such function or - table, the facility still operates, and performs whatever part of - its purpose remains meaningful. - - (For example, a function in a library to compute square roots has - a purpose that is entirely well-defined independent of the - application. Therefore, Subsection 2d requires that any - application-supplied function or table used by this function must - be optional: if the application does not supply it, the square - root function must still compute square roots.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Library, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Library, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote -it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Library. - -In addition, mere aggregation of another work not based on the Library -with the Library (or with a work based on the Library) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may opt to apply the terms of the ordinary GNU General Public -License instead of this License to a given copy of the Library. To do -this, you must alter all the notices that refer to this License, so -that they refer to the ordinary GNU General Public License, version 2, -instead of to this License. (If a newer version than version 2 of the -ordinary GNU General Public License has appeared, then you can specify -that version instead if you wish.) Do not make any other change in -these notices. - - Once this change is made in a given copy, it is irreversible for -that copy, so the ordinary GNU General Public License applies to all -subsequent copies and derivative works made from that copy. - - This option is useful when you wish to copy part of the code of -the Library into a program that is not a library. - - 4. You may copy and distribute the Library (or a portion or -derivative of it, under Section 2) in object code or executable form -under the terms of Sections 1 and 2 above provided that you accompany -it with the complete corresponding machine-readable source code, which -must be distributed under the terms of Sections 1 and 2 above on a -medium customarily used for software interchange. - - If distribution of object code is made by offering access to copy -from a designated place, then offering equivalent access to copy the -source code from the same place satisfies the requirement to -distribute the source code, even though third parties are not -compelled to copy the source along with the object code. - - 5. A program that contains no derivative of any portion of the -Library, but is designed to work with the Library by being compiled or -linked with it, is called a "work that uses the Library". Such a -work, in isolation, is not a derivative work of the Library, and -therefore falls outside the scope of this License. - - However, linking a "work that uses the Library" with the Library -creates an executable that is a derivative of the Library (because it -contains portions of the Library), rather than a "work that uses the -library". The executable is therefore covered by this License. -Section 6 states terms for distribution of such executables. - - When a "work that uses the Library" uses material from a header file -that is part of the Library, the object code for the work may be a -derivative work of the Library even though the source code is not. -Whether this is true is especially significant if the work can be -linked without the Library, or if the work is itself a library. The -threshold for this to be true is not precisely defined by law. - - If such an object file uses only numerical parameters, data -structure layouts and accessors, and small macros and small inline -functions (ten lines or less in length), then the use of the object -file is unrestricted, regardless of whether it is legally a derivative -work. (Executables containing this object code plus portions of the -Library will still fall under Section 6.) - - Otherwise, if the work is a derivative of the Library, you may -distribute the object code for the work under the terms of Section 6. -Any executables containing that work also fall under Section 6, -whether or not they are linked directly with the Library itself. - - 6. As an exception to the Sections above, you may also combine or -link a "work that uses the Library" with the Library to produce a -work containing portions of the Library, and distribute that work -under terms of your choice, provided that the terms permit -modification of the work for the customer's own use and reverse -engineering for debugging such modifications. - - You must give prominent notice with each copy of the work that the -Library is used in it and that the Library and its use are covered by -this License. You must supply a copy of this License. If the work -during execution displays copyright notices, you must include the -copyright notice for the Library among them, as well as a reference -directing the user to the copy of this License. Also, you must do one -of these things: - - a) Accompany the work with the complete corresponding - machine-readable source code for the Library including whatever - changes were used in the work (which must be distributed under - Sections 1 and 2 above); and, if the work is an executable linked - with the Library, with the complete machine-readable "work that - uses the Library", as object code and/or source code, so that the - user can modify the Library and then relink to produce a modified - executable containing the modified Library. (It is understood - that the user who changes the contents of definitions files in the - Library will not necessarily be able to recompile the application - to use the modified definitions.) - - b) Use a suitable shared library mechanism for linking with the - Library. A suitable mechanism is one that (1) uses at run time a - copy of the library already present on the user's computer system, - rather than copying library functions into the executable, and (2) - will operate properly with a modified version of the library, if - the user installs one, as long as the modified version is - interface-compatible with the version that the work was made with. - - c) Accompany the work with a written offer, valid for at - least three years, to give the same user the materials - specified in Subsection 6a, above, for a charge no more - than the cost of performing this distribution. - - d) If distribution of the work is made by offering access to copy - from a designated place, offer equivalent access to copy the above - specified materials from the same place. - - e) Verify that the user has already received a copy of these - materials or that you have already sent this user a copy. - - For an executable, the required form of the "work that uses the -Library" must include any data and utility programs needed for -reproducing the executable from it. However, as a special exception, -the materials to be distributed need not include anything that is -normally distributed (in either source or binary form) with the major -components (compiler, kernel, and so on) of the operating system on -which the executable runs, unless that component itself accompanies -the executable. - - It may happen that this requirement contradicts the license -restrictions of other proprietary libraries that do not normally -accompany the operating system. Such a contradiction means you cannot -use both them and the Library together in an executable that you -distribute. - - 7. You may place library facilities that are a work based on the -Library side-by-side in a single library together with other library -facilities not covered by this License, and distribute such a combined -library, provided that the separate distribution of the work based on -the Library and of the other library facilities is otherwise -permitted, and provided that you do these two things: - - a) Accompany the combined library with a copy of the same work - based on the Library, uncombined with any other library - facilities. This must be distributed under the terms of the - Sections above. - - b) Give prominent notice with the combined library of the fact - that part of it is a work based on the Library, and explaining - where to find the accompanying uncombined form of the same work. - - 8. You may not copy, modify, sublicense, link with, or distribute -the Library except as expressly provided under this License. Any -attempt otherwise to copy, modify, sublicense, link with, or -distribute the Library is void, and will automatically terminate your -rights under this License. However, parties who have received copies, -or rights, from you under this License will not have their licenses -terminated so long as such parties remain in full compliance. - - 9. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Library or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Library (or any work based on the -Library), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Library or works based on it. - - 10. Each time you redistribute the Library (or any work based on the -Library), the recipient automatically receives a license from the -original licensor to copy, distribute, link with or modify the Library -subject to these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties with -this License. - - 11. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Library at all. For example, if a patent -license would not permit royalty-free redistribution of the Library by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Library. - -If any portion of this section is held invalid or unenforceable under any -particular circumstance, the balance of the section is intended to apply, -and the section as a whole is intended to apply in other circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 12. If the distribution and/or use of the Library is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Library under this License may add -an explicit geographical distribution limitation excluding those countries, -so that distribution is permitted only in or among countries not thus -excluded. In such case, this License incorporates the limitation as if -written in the body of this License. - - 13. The Free Software Foundation may publish revised and/or new -versions of the Lesser General Public License from time to time. -Such new versions will be similar in spirit to the present version, -but may differ in detail to address new problems or concerns. - -Each version is given a distinguishing version number. If the Library -specifies a version number of this License which applies to it and -"any later version", you have the option of following the terms and -conditions either of that version or of any later version published by -the Free Software Foundation. If the Library does not specify a -license version number, you may choose any version ever published by -the Free Software Foundation. - - 14. If you wish to incorporate parts of the Library into other free -programs whose distribution conditions are incompatible with these, -write to the author to ask for permission. For software which is -copyrighted by the Free Software Foundation, write to the Free -Software Foundation; we sometimes make exceptions for this. Our -decision will be guided by the two goals of preserving the free status -of all derivatives of our free software and of promoting the sharing -and reuse of software generally. - - NO WARRANTY - - 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO -WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. -EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR -OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY -KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE -IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE -LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME -THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN -WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY -AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU -FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR -CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE -LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING -RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A -FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF -SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH -DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Libraries - - If you develop a new library, and you want it to be of the greatest -possible use to the public, we recommend making it free software that -everyone can redistribute and change. You can do so by permitting -redistribution under these terms (or, alternatively, under the terms of the -ordinary General Public License). - - To apply these terms, attach the following notices to the library. It is -safest to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least the -"copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This library is free software; you can redistribute it and/or - modify it under the terms of the GNU Lesser General Public - License as published by the Free Software Foundation; either - version 2.1 of the License, or (at your option) any later version. - - This library is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Additional equipment should be - * used to verify the samples directly from the chip, and allow this exact - * per-sample correspondence. As a good side-effect, since this emulator uses - * floating point and has a more fine-grained envelope generator, it can produce - * sometimes a crystal-clear, denser kind of OPL3 sound that, because of that, - * may be useful for creating new music. - * - * Version 1.0.6 - * - */ - -#include -#include -#include -#include - -#include "opl.h" -#include "opl3_Float.h" - -#define VOLUME_MUL 0.3333 - -static const double OPL_PI = 3.14159265358979323846; // matches value in gcc v2 math.h - -namespace JavaOPL3 -{ - -class Operator; - -static inline double StripIntPart(double num) -{ -#if 0 - double dontcare; - return modf(num, &dontcare); -#else - return num - xs_RoundToInt(num); -#endif -} - -// -// Channels -// - - -class Channel -{ -protected: - double feedback[2]; - - int fnuml, fnumh, kon, block, fb, cha, chb, cnt; - - // Factor to convert between normalized amplitude to normalized - // radians.

- this results in only 256 steps instead of normal 1024. - In other words: - when SSG-EG is disabled, the step inside of the EG is one, - when SSG-EG is enabled, the step is four (in Decay and Sustain phases). - - Times between the level changes are the same in both modes. - - - Important: - Decay 1 Level (so called SL) is compared to actual SSG-EG output, so - it is the same in both SSG and no-SSG modes, with this exception: - - when the SSG-EG is enabled and is generating raising levels - (when the EG output is inverted) the SL will be found at wrong level !!! - For example, when SL=02: - 0 -6 = -6dB in non-inverted EG output - 96-6 = -90dB in inverted EG output - Which means that EG compares its level to SL as usual, and that the - output is simply inverted afterall. - - - The Yamaha's manuals say that AR should be set to 0x1f (max speed). - That is not necessary, but then EG will be generating Attack phase. - - */ - - - break;

It also counts - as the successor of the GNU Library Public License, version 2, hence - the version number 2.1.] - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -Licenses are intended to guarantee your freedom to share and change -free software--to make sure the software is free for all its users. - - This license, the Lesser General Public License, applies to some -specially designated software packages--typically libraries--of the -Free Software Foundation and other authors who decide to use it. You -can use it too, but we suggest you first think carefully about whether -this license or the ordinary General Public License is the better -strategy to use in any particular case, based on the explanations below. - - When we speak of free software, we are referring to freedom of use, -not price. Our General Public Licenses are designed to make sure that -you have the freedom to distribute copies of free software (and charge -for this service if you wish); that you receive source code or can get -it if you want it; that you can change the software and use pieces of -it in new free programs; and that you are informed that you can do -these things. - - To protect your rights, we need to make restrictions that forbid -distributors to deny you these rights or to ask you to surrender these -rights. These restrictions translate to certain responsibilities for -you if you distribute copies of the library or if you modify it. - - For example, if you distribute copies of the library, whether gratis -or for a fee, you must give the recipients all the rights that we gave -you. You must make sure that they, too, receive or can get the source -code. If you link other code with the library, you must provide -complete object files to the recipients, so that they can relink them -with the library after making changes to the library and recompiling -it. And you must show them these terms so they know their rights. - - We protect your rights with a two-step method: (1) we copyright the -library, and (2) we offer you this license, which gives you legal -permission to copy, distribute and/or modify the library. - - To protect each distributor, we want to make it very clear that -there is no warranty for the free library. Also, if the library is -modified by someone else and passed on, the recipients should know -that what they have is not the original version, so that the original -author's reputation will not be affected by problems that might be -introduced by others. - - Finally, software patents pose a constant threat to the existence of -any free program. We wish to make sure that a company cannot -effectively restrict the users of a free program by obtaining a -restrictive license from a patent holder. Therefore, we insist that -any patent license obtained for a version of the library must be -consistent with the full freedom of use specified in this license. - - Most GNU software, including some libraries, is covered by the -ordinary GNU General Public License. This license, the GNU Lesser -General Public License, applies to certain designated libraries, and -is quite different from the ordinary General Public License. We use -this license for certain libraries in order to permit linking those -libraries into non-free programs. - - When a program is linked with a library, whether statically or using -a shared library, the combination of the two is legally speaking a -combined work, a derivative of the original library. The ordinary -General Public License therefore permits such linking only if the -entire combination fits its criteria of freedom. The Lesser General -Public License permits more lax criteria for linking other code with -the library. - - We call this license the "Lesser" General Public License because it -does Less to protect the user's freedom than the ordinary General -Public License. It also provides other free software developers Less -of an advantage over competing non-free programs. These disadvantages -are the reason we use the ordinary General Public License for many -libraries. However, the Lesser license provides advantages in certain -special circumstances. - - For example, on rare occasions, there may be a special need to -encourage the widest possible use of a certain library, so that it becomes -a de-facto standard. To achieve this, non-free programs must be -allowed to use the library. A more frequent case is that a free -library does the same job as widely used non-free libraries. In this -case, there is little to gain by limiting the free library to free -software only, so we use the Lesser General Public License. - - In other cases, permission to use a particular library in non-free -programs enables a greater number of people to use a large body of -free software. For example, permission to use the GNU C Library in -non-free programs enables many more people to use the whole GNU -operating system, as well as its variant, the GNU/Linux operating -system. - - Although the Lesser General Public License is Less protective of the -users' freedom, it does ensure that the user of a program that is -linked with the Library has the freedom and the wherewithal to run -that program using a modified version of the Library. - - The precise terms and conditions for copying, distribution and -modification follow. Pay close attention to the difference between a -"work based on the library" and a "work that uses the library". The -former contains code derived from the library, whereas the latter must -be combined with the library in order to run. - - GNU LESSER GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License Agreement applies to any software library or other -program which contains a notice placed by the copyright holder or -other authorized party saying it may be distributed under the terms of -this Lesser General Public License (also called "this License"). -Each licensee is addressed as "you". - - A "library" means a collection of software functions and/or data -prepared so as to be conveniently linked with application programs -(which use some of those functions and data) to form executables. - - The "Library", below, refers to any such software library or work -which has been distributed under these terms. A "work based on the -Library" means either the Library or any derivative work under -copyright law: that is to say, a work containing the Library or a -portion of it, either verbatim or with modifications and/or translated -straightforwardly into another language. (Hereinafter, translation is -included without limitation in the term "modification".) - - "Source code" for a work means the preferred form of the work for -making modifications to it. For a library, complete source code means -all the source code for all modules it contains, plus any associated -interface definition files, plus the scripts used to control compilation -and installation of the library. - - Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running a program using the Library is not restricted, and output from -such a program is covered only if its contents constitute a work based -on the Library (independent of the use of the Library in a tool for -writing it). Whether that is true depends on what the Library does -and what the program that uses the Library does. - - 1. You may copy and distribute verbatim copies of the Library's -complete source code as you receive it, in any medium, provided that -you conspicuously and appropriately publish on each copy an -appropriate copyright notice and disclaimer of warranty; keep intact -all the notices that refer to this License and to the absence of any -warranty; and distribute a copy of this License along with the -Library. - - You may charge a fee for the physical act of transferring a copy, -and you may at your option offer warranty protection in exchange for a -fee. - - 2. You may modify your copy or copies of the Library or any portion -of it, thus forming a work based on the Library, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) The modified work must itself be a software library. - - b) You must cause the files modified to carry prominent notices - stating that you changed the files and the date of any change. - - c) You must cause the whole of the work to be licensed at no - charge to all third parties under the terms of this License. - - d) If a facility in the modified Library refers to a function or a - table of data to be supplied by an application program that uses - the facility, other than as an argument passed when the facility - is invoked, then you must make a good faith effort to ensure that, - in the event an application does not supply such function or - table, the facility still operates, and performs whatever part of - its purpose remains meaningful. - - (For example, a function in a library to compute square roots has - a purpose that is entirely well-defined independent of the - application. Therefore, Subsection 2d requires that any - application-supplied function or table used by this function must - be optional: if the application does not supply it, the square - root function must still compute square roots.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Library, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Library, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote -it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Library. - -In addition, mere aggregation of another work not based on the Library -with the Library (or with a work based on the Library) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may opt to apply the terms of the ordinary GNU General Public -License instead of this License to a given copy of the Library. To do -this, you must alter all the notices that refer to this License, so -that they refer to the ordinary GNU General Public License, version 2, -instead of to this License. (If a newer version than version 2 of the -ordinary GNU General Public License has appeared, then you can specify -that version instead if you wish.) Do not make any other change in -these notices. - - Once this change is made in a given copy, it is irreversible for -that copy, so the ordinary GNU General Public License applies to all -subsequent copies and derivative works made from that copy. - - This option is useful when you wish to copy part of the code of -the Library into a program that is not a library. - - 4. You may copy and distribute the Library (or a portion or -derivative of it, under Section 2) in object code or executable form -under the terms of Sections 1 and 2 above provided that you accompany -it with the complete corresponding machine-readable source code, which -must be distributed under the terms of Sections 1 and 2 above on a -medium customarily used for software interchange. - - If distribution of object code is made by offering access to copy -from a designated place, then offering equivalent access to copy the -source code from the same place satisfies the requirement to -distribute the source code, even though third parties are not -compelled to copy the source along with the object code. - - 5. A program that contains no derivative of any portion of the -Library, but is designed to work with the Library by being compiled or -linked with it, is called a "work that uses the Library". Such a -work, in isolation, is not a derivative work of the Library, and -therefore falls outside the scope of this License. - - However, linking a "work that uses the Library" with the Library -creates an executable that is a derivative of the Library (because it -contains portions of the Library), rather than a "work that uses the -library". The executable is therefore covered by this License. -Section 6 states terms for distribution of such executables. - - When a "work that uses the Library" uses material from a header file -that is part of the Library, the object code for the work may be a -derivative work of the Library even though the source code is not. -Whether this is true is especially significant if the work can be -linked without the Library, or if the work is itself a library. The -threshold for this to be true is not precisely defined by law. - - If such an object file uses only numerical parameters, data -structure layouts and accessors, and small macros and small inline -functions (ten lines or less in length), then the use of the object -file is unrestricted, regardless of whether it is legally a derivative -work. (Executables containing this object code plus portions of the -Library will still fall under Section 6.) - - Otherwise, if the work is a derivative of the Library, you may -distribute the object code for the work under the terms of Section 6. -Any executables containing that work also fall under Section 6, -whether or not they are linked directly with the Library itself. - - 6. As an exception to the Sections above, you may also combine or -link a "work that uses the Library" with the Library to produce a -work containing portions of the Library, and distribute that work -under terms of your choice, provided that the terms permit -modification of the work for the customer's own use and reverse -engineering for debugging such modifications. - - You must give prominent notice with each copy of the work that the -Library is used in it and that the Library and its use are covered by -this License. You must supply a copy of this License. If the work -during execution displays copyright notices, you must include the -copyright notice for the Library among them, as well as a reference -directing the user to the copy of this License. Also, you must do one -of these things: - - a) Accompany the work with the complete corresponding - machine-readable source code for the Library including whatever - changes were used in the work (which must be distributed under - Sections 1 and 2 above); and, if the work is an executable linked - with the Library, with the complete machine-readable "work that - uses the Library", as object code and/or source code, so that the - user can modify the Library and then relink to produce a modified - executable containing the modified Library. (It is understood - that the user who changes the contents of definitions files in the - Library will not necessarily be able to recompile the application - to use the modified definitions.) - - b) Use a suitable shared library mechanism for linking with the - Library. A suitable mechanism is one that (1) uses at run time a - copy of the library already present on the user's computer system, - rather than copying library functions into the executable, and (2) - will operate properly with a modified version of the library, if - the user installs one, as long as the modified version is - interface-compatible with the version that the work was made with. - - c) Accompany the work with a written offer, valid for at - least three years, to give the same user the materials - specified in Subsection 6a, above, for a charge no more - than the cost of performing this distribution. - - d) If distribution of the work is made by offering access to copy - from a designated place, offer equivalent access to copy the above - specified materials from the same place. - - e) Verify that the user has already received a copy of these - materials or that you have already sent this user a copy. - - For an executable, the required form of the "work that uses the -Library" must include any data and utility programs needed for -reproducing the executable from it. However, as a special exception, -the materials to be distributed need not include anything that is -normally distributed (in either source or binary form) with the major -components (compiler, kernel, and so on) of the operating system on -which the executable runs, unless that component itself accompanies -the executable. - - It may happen that this requirement contradicts the license -restrictions of other proprietary libraries that do not normally -accompany the operating system. Such a contradiction means you cannot -use both them and the Library together in an executable that you -distribute. - - 7. You may place library facilities that are a work based on the -Library side-by-side in a single library together with other library -facilities not covered by this License, and distribute such a combined -library, provided that the separate distribution of the work based on -the Library and of the other library facilities is otherwise -permitted, and provided that you do these two things: - - a) Accompany the combined library with a copy of the same work - based on the Library, uncombined with any other library - facilities. This must be distributed under the terms of the - Sections above. - - b) Give prominent notice with the combined library of the fact - that part of it is a work based on the Library, and explaining - where to find the accompanying uncombined form of the same work. - - 8. You may not copy, modify, sublicense, link with, or distribute -the Library except as expressly provided under this License. Any -attempt otherwise to copy, modify, sublicense, link with, or -distribute the Library is void, and will automatically terminate your -rights under this License. However, parties who have received copies, -or rights, from you under this License will not have their licenses -terminated so long as such parties remain in full compliance. - - 9. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Library or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Library (or any work based on the -Library), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Library or works based on it. - - 10. Each time you redistribute the Library (or any work based on the -Library), the recipient automatically receives a license from the -original licensor to copy, distribute, link with or modify the Library -subject to these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties with -this License. - - 11. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Library at all. For example, if a patent -license would not permit royalty-free redistribution of the Library by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Library. - -If any portion of this section is held invalid or unenforceable under any -particular circumstance, the balance of the section is intended to apply, -and the section as a whole is intended to apply in other circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 12. If the distribution and/or use of the Library is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Library under this License may add -an explicit geographical distribution limitation excluding those countries, -so that distribution is permitted only in or among countries not thus -excluded. In such case, this License incorporates the limitation as if -written in the body of this License. - - 13. The Free Software Foundation may publish revised and/or new -versions of the Lesser General Public License from time to time. -Such new versions will be similar in spirit to the present version, -but may differ in detail to address new problems or concerns. - -Each version is given a distinguishing version number. If the Library -specifies a version number of this License which applies to it and -"any later version", you have the option of following the terms and -conditions either of that version or of any later version published by -the Free Software Foundation. If the Library does not specify a -license version number, you may choose any version ever published by -the Free Software Foundation. - - 14. If you wish to incorporate parts of the Library into other free -programs whose distribution conditions are incompatible with these, -write to the author to ask for permission. For software which is -copyrighted by the Free Software Foundation, write to the Free -Software Foundation; we sometimes make exceptions for this. Our -decision will be guided by the two goals of preserving the free status -of all derivatives of our free software and of promoting the sharing -and reuse of software generally. - - NO WARRANTY - - 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO -WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. -EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR -OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY -KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE -IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE -LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME -THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN -WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY -AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU -FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR -CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE -LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING -RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A -FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF -SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH -DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Libraries - - If you develop a new library, and you want it to be of the greatest -possible use to the public, we recommend making it free software that -everyone can redistribute and change. You can do so by permitting -redistribution under these terms (or, alternatively, under the terms of the -ordinary General Public License). - - To apply these terms, attach the following notices to the library. It is -safest to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least the -"copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This library is free software; you can redistribute it and/or - modify it under the terms of the GNU Lesser General Public - License as published by the Free Software Foundation; either - version 2.1 of the License, or (at your option) any later version. - - This library is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Well Chris, TiMidity is a software-only synthesizer, MIDI - renderer, MIDI to WAVE converter, realtime MIDI player for UNIX machines, - even (I've heard) a Netscape helper application. It takes a MIDI file - and writes a WAVE or raw PCM data or plays it on your digital audio - device. It sounds much more realistic than FM synthesis, but you need a - ~100Mhz processor to listen to 32kHz stereo music in the background while - you work. 11kHz mono can be played on a low-end 486, and, to some, it - still sounds better than FM. - --------------------------------------------------------------------------- -Q: I don't have a GUS, can I use TiMidity? - -A: Yes. That's the point. You don't need a Gravis Ultrasound to use - TiMidity, you just need GUS-compatible patches, which are freely - available on the Internet. See below for pointers. - --------------------------------------------------------------------------- -Q: I have a GUS, can I use TiMidity? - -A: The DOS port doesn't have GUS support, and TiMidity won't be taking - advantage of the board's internal synthesizer under other operating - systems either. So it kind of defeats the purpose. But you can use it. - --------------------------------------------------------------------------- -Q: I tried playing a MIDI file I got off the Net but all I got was a - dozen warnings saying "No instrument mapped to tone bank 0, program - xx - this instrument will not be heard". What's wrong? - -A: The General MIDI standard specifies 128 melodic instruments and - some sixty percussion sounds. If you wish to play arbitrary General - MIDI files, you'll need to get more patch files. - - There's a program called Midia for SGI's, which also plays MIDI - files and has a lot more bells and whistles than TiMidity. It uses - GUS-compatible patches, too -- so you can get the 8 MB set at - ftp://archive.cs.umbc.edu/pub/midia for pretty good GM compatibility. - - There are also many excellent patches on the Ultrasound FTP sites. - I can recommend Dustin McCartney's collections gsdrum*.zip and - wow*.zip in the "[.../]sound/patches/files" directory. The huge - ProPats series (pp3-*.zip) contains good patches as well. General - MIDI files can also be found on these sites. - - This site list is from the GUS FAQ: - -> FTP Sites Archive Directories -> --------- ------------------- -> Main N.American Site: archive.orst.edu pub/packages/gravis -> wuarchive.wustl.edu systems/ibmpc/ultrasound -> Main Asian Site: nctuccca.edu.tw PC/ultrasound -> Main European Site: src.doc.ic.ac.uk packages/ultrasound -> Main Australian Site: ftp.mpx.com.au /ultrasound/general -> /ultrasound/submit -> South African Site: ftp.sun.ac.za /pub/packages/ultrasound -> Submissions: archive.epas.utoronto.ca pub/pc/ultrasound/submit -> Newly Validated Files: archive.epas.utoronto.ca pub/pc/ultrasound -> -> Mirrors: garbo.uwasa.fi mirror/ultrasound -> ftp.st.nepean.uws.edu.au pc/ultrasound -> ftp.luth.se pub/msdos/ultrasound - --------------------------------------------------------------------------- -Q: Some files have awful clicks and pops. - -A: Find out which patch is responsible for the clicking (try "timidity - -P ".

When I run Netscape, - the sound gets choppy and it takes ten minutes to load. What can I do? - -A: Here are some things to try: - - - Use a lower sampling rate. - - - Use mono output. This can improve performance by 10-30%. - (Using 8-bit instead of 16-bit output makes no difference.) - - - Use a smaller number of simultaneous voices. - - - Make sure you compiled with FAST_DECAY enabled in options.h - - - Recompile with an Intel-optimized gcc for a 5-15% - performance increase. - --------------------------------------------------------------------------- diff --git a/libraries/timidity/README b/libraries/timidity/README deleted file mode 100644 index 9c9c55aad..000000000 --- a/libraries/timidity/README +++ /dev/null @@ -1,61 +0,0 @@ -[This version of timidity has been stripped for simplicity in porting to SDL, -and then even further for SDL_sound] ----------------------------------*-text-*--------------------------------- - - From http://www.cgs.fi/~tt/discontinued.html : - - If you'd like to continue hacking on TiMidity, feel free.

A September 5th message - * to Masanao Izumo is discussing a problem with a "reapxg.mid", a file which - * I still have, and how it issues an MSB=0 with a program change on ch 9, - * thus turning it into a melodic channel. The strange thing is, this doesn't - * happen on XG hardware, nor on the XG softsynth. It continues to play as a - * normal drum. The author of the midi file obviously intended it to be - * drumset 16 too. The original fix was to detect LSB == -1, then break so - * as to not set it to a melodic channel. I'm guessing that this somehow got - * mutated into checking for 127 instead, and the current FIXME is related to - * the original hack from Sept 1999. The Sept 5th email discusses patches - * being applied to version 2.5.1 to get XG drums to work properly, and a - * Sept 7th email to someone else discusses the fixes being part of the - * latest 2.6.0-beta3. A September 23rd email to Masanao Izumo specifically - * mentions the LSB == -1 hack (and reapxg.mid not playing "correctly" - * anymore), as well as new changes in 2.6.0 that broke a lot of other XG - * files (XG drum support was extremely buggy in 1999 and we were still trying - * to figure out how to initialize things to reproduce hardware behavior). An - * October 5th email says that 2.5.1 was correct, 2.6.0 had very broken XG - * drum changes, and 2.6.1 still has problems. Further discussions ensued - * over what was "correct": to follow the XG spec, or to reproduce - * "features" / bugs in the hardware. I can't find the rest of the - * discussions, but I think it ended with us agreeing to just follow the spec - * and not try to reproduce the hardware strangeness. I don't know how the - * current FIXME wound up the way it is now. I'm still going to guess it is - * related to the old reapxg.mid hack. - * - * Now that reset_midi() initializes channel[ch].bank_lsb to 0 instead of -1, - * checking for LSB == -1 won't do anything anymore, so changing the above - * FIXME to the original == -1 won't do any good. It is best to just #if 0 - * it out and leave it here as a reminder that there is at least one XG - * hardware / softsynth "bug" that is not reproduced by timidity at the - * moment. - * - * If the current FIXME actually reproduces some other XG hadware bug that - * I don't know about, then it may have a valid purpose. I just don't know - * what that purpose is at the moment. Perhaps someone else does? I still - * have src going back to 2.10.4, and the FIXME comment was already there by - * then. I don't see any entries in the Changelog that could explain it - * either. If someone has src from 2.5.1 through 2.10.3 and wants to - * investigate this further, go for it :) - */ - midi_drumpart_change(ch, 0); - channel[ch].mapID = XG_NORMAL_MAP; - dr = ISDRUMCHANNEL(ch); - break; - case 64: /* SFX voice */ - midi_drumpart_change(ch, 0); - channel[ch].mapID = XG_SFX64_MAP; - dr = ISDRUMCHANNEL(ch); - break; - case 126: /* SFX kit */ - midi_drumpart_change(ch, 1); - channel[ch].mapID = XG_SFX126_MAP; - dr = ISDRUMCHANNEL(ch); - break; - case 127: /* Drum kit */ - midi_drumpart_change(ch, 1); - channel[ch].mapID = XG_DRUM_MAP; - dr = ISDRUMCHANNEL(ch); - break; - default: - break; - } - newbank = channel[ch].bank_lsb; - break; - case GM2_SYSTEM_MODE: /* GM2 */ - if ((channel[ch].bank_msb & 0xfe) == 0x78) { /* 0x78/0x79 */ - midi_drumpart_change(ch, channel[ch].bank_msb == 0x78); - dr = ISDRUMCHANNEL(ch); - } - channel[ch].mapID = (dr) ?

Better speed and higher - accuracy than Newton. This isn't *quite* true Gauss interpolation; it's - more a slightly modified Gauss interpolation that I accidently stumbled - upon. Rather than normalize all x values in the window to be in the range - [0 to 2*PI], it simply divides them all by 2*PI instead. I don't know why - this works, but it does. Gauss should only work on periodic data with the - window spanning exactly one period, so it is no surprise that regular Gauss - interpolation doesn't work too well on general audio data. But dividing - the x values by 2*PI magically does. Any other scaling produces degraded - results or total garbage. If anyone can work out the theory behind why - this works so well (at first glance, it shouldn't ??), please contact me - (Eric A. Welsh, ewelsh@ccb.wustl.edu), as I would really like to have some - mathematical justification for doing this. Despite the lack of any sound - theoretical basis, this method DOES result in highly accurate interpolation - (or possibly approximaton, not sure yet if it truly interpolates, but it - looks like it does). -N 34 is as high as it can go before errors start - appearing. But even at -N 34, it is more accurate than Newton at -N 57. - -N 34 has no problem running in realtime on my system, but -N 25 is the - default, since that is the optimal compromise between speed and accuracy. - I strongly recommend using Gauss interpolation. It is the highest - quality interpolation option available, and is much faster than using - Newton polynomials. */ - - -static resample_t resample_gauss(sample_t *src, splen_t ofs, resample_rec_t *rec) -{ - sample_t *sptr;

This seems to happen a lot, therefore I am trying to explain in advance. - * - * The mpg123 library decides what output format to use when encountering the first frame in a stream, or actually any frame that is still valid but differs from the frames before in the prompted output format. At such a deciding point, an internal table of allowed encodings, sampling rates and channel setups is consulted. According to this table, an output format is chosen and the decoding engine set up accordingly (including ptimized routines for different output formats). This might seem unusual but it just follows from the non-existence of "MPEG audio files" with defined overall properties. There are streams, streams are concatenations of (semi) independent frames. We store streams on disk and call them "MPEG audio files", but that does not change their nature as the decoder is concerned (the LAME/Xing header for gapless decoding makes things interesting again). - * - * To get to the point: What you do with mpg123_format() and friends is to fill the internal table of allowed formats before it is used. That includes removing support for some formats or adding your forced sample rate (see MPG123_FORCE_RATE) that will be used with the crude internal resampler. Also keep in mind that the sample encoding is just a question of choice -- the MPEG frames do only indicate their native sampling rate and channel count. If you want to decode to integer or float samples, 8 or 16 bit ... that is your decision. In a "clean" world, libmpg123 would always decode to 32 bit float and let you handle any sample conversion. But there are optimized routines that work faster by directly decoding to the desired encoding / accuracy. We prefer efficiency over conceptual tidyness. - * - * People often start out thinking that mpg123_format() should change the actual decoding format on the fly. That is wrong. It only has effect on the next natural change of output format, when libmpg123 will consult its format table again. To make life easier, you might want to call mpg123_format_none() before any thing else and then just allow one desired encoding and a limited set of sample rates / channel choices that you actually intend to deal with. You can force libmpg123 to decode everything to 44100 KHz, stereo, 16 bit integer ... it will duplicate mono channels and even do resampling if needed (unless that feature is disabled in the build, same with some encodings). But I have to stress that the resampling of libmpg123 is very crude and doesn't even contain any kind of "proper" interpolation. - * - * In any case, watch out for MPG123_NEW_FORMAT as return message from decoding routines and call mpg123_getformat() to get the currently active output format. - * - * @{ - */ - -/** An enum over all sample types possibly known to mpg123. - * The values are designed as bit flags to allow bitmasking for encoding families. - * - * Note that (your build of) libmpg123 does not necessarily support all these. - * Usually, you can expect the 8bit encodings and signed 16 bit. - * Also 32bit float will be usual beginning with mpg123-1.7.0 . - * What you should bear in mind is that (SSE, etc) optimized routines may be absent - * for some formats.
