Speed up resamplers by removing lots of implicit function calls
commit 9b884676b9c6afbc4bbe889e7e33a10cffa0e90c
Author: Randy Heit <rheit@users.noreply.github.com>
Date: Sat Mar 7 21:49:57 2015 -0600
Remove direct access to the FP aliasing mixer
The original integer one is faster, and using floats gains nothing here,
so don't bother offering it.
commit 8f9fc8d3317f0db3480577b2c92963dc88f609d0
Author: Randy Heit <rheit@users.noreply.github.com>
Date: Sat Mar 7 20:14:34 2015 -0600
Use unsigned phase counters in the resampler
- delta should always be positive
commit d1228954405bbcd036de66e9bcbe443657cfc590
Author: Randy Heit <rheit@users.noreply.github.com>
Date: Fri Mar 6 23:09:14 2015 -0600
Restore DUMB's original resamplers
- The all-in-one resamplers in resampler.c have more overhead than the
originals, so bring them back. Specifically, the aliasing, linear, and
cubic resamplers have been restored to their previous form. Also, this
is the original aliasing filter and not the blip_buf one. The
resampler.c resamplers are still accessible but at different quality numbers.
commit 730e5d98a0c127b9177e5364752d47a82416a0e4
Author: Randy Heit <rheit@users.noreply.github.com>
Date: Fri Mar 6 22:00:06 2015 -0600
Convert phase back to integers
- Having to call functions to convert to integer and chop off the
non-decimal part of the phase for every sample is super heavyweight.
commit a6325a54e77d2c523f3637c963a41314287b1b0f
Author: Randy Heit <rheit@users.noreply.github.com>

Remove fir_resampler files
- What are these still doing here?
commit 7f3ebf9b7fa9c9ba9e579b081a263f0e7f949da5
Author: Randy Heit <rheit@users.noreply.github.com>
Date: Fri Mar 6 20:01:53 2015 -0600
Try to eek out some more performance from new resamplers
- Change some floats to doubles to avoid extra conversions.
- Use modf() instead of fmod(), since it seems at least marginally faster.

Resampler now adds input delay and subtracts output delay according to whichever quality is selected, rather than being fixed for sinc only. This fixes blep synthesis mode defeating note on and off volume ramping.

except for XM. Fixed.
- Mask tick count to 0-31 so it can't overflow the arpeggio tables.

- Moved IT S70-2 effects alongside the rest of S7x so they all trigger after
paired notes.
- Integrated note on/cut ramping with volume transition ramping to reduce
setup/cleanup overhead of calling render_playing and the resampler functions
for single samples.
- Note on/cut ramping scaled from 7 sample logarithmic and 256 sample linear to
.75ms and 5ms respectively, both linear.
- Integrated the pattern looping changes from DUMB 0.9.3, since a few files
seemed to be broken. The XM-only features still needed to be flagged for XM
so they won't break MOD.

a loop will never jump to the first loop point.

- Simplified volume ramping update code, reducing the size of the resampler code
considerably.
- Bumped the volume ramping precision to 24 bits of fraction precision, which is
needed by Sweetsin.xm.
- Moved sample rate reporting to dynamic info as requested by Peter, since it's
not a property of the files themselves, but user configurable.

- Shuffled finetune calculation into the correct position, immediately applied
as delta is calculated from note.
- Promoted IT_SAMPLE finetune property to signed short as char is insufficient
for full semitone range. (+/- 256)
- Changed resampler to use full 64-bit comparison for todo variable range checking
which should hopefully eliminate any further problems with pitch slides which go
out of range.

{5/31/2006 8:36:12 PM}2006-05-30 03:57 UTC - kode54
- IT reader works around a broken file that has several of the instruments
offset by two bytes from their indicated file offsets. Since the hack
only checks for offset by two null bytes, it also assumes that the two
bytes it can't read from the end are also zero. (bz_ult9.it)
- IT reader treats null instrument/sample/pattern offsets as empty items.

- S3M reader defaults to maximum (128) global volume when the header value is
either zero or greater than 64. (darkness2.s3m)

commit 4e1db2adb05e53c50fe38102676889c22a4f2e66

{5/26/2006 10:58:10 PM~5/26/2006 10:58:12 PM}2006-05-22 21:44 UTC - kode54
- XM reader now supports up to 256 instruments, even though FT2 only
supports up to 128. ModPlug Tracker again.
2006-05-22 18:43 UTC - kode54
- S3M reader was using the incorrect index into component for sample packing
when reading sample data. Was using n, should have been m.
2006-05-22 17:26 UTC - kode54
- IT renderer may have a bug with its time_lost / loop handling. Switchover
from sustain loop would compound time_lost onto itself for every note-off.
I'm not sure if this crap is even doing the right thing, especially in the
case of a sample with a sustain loop, but no main loop. Working around for
now by zeroing time_lost after note-off. (hall8.it)
- S3M reader ignores effects outside of 1-25 range so nothing can hit
internal effects which are XM or PTM only. (N4.S3M)
- IT reader now supports ModPlug Tracker extensions for up to 4000 samples
and mapping them with instruments. (hallowe.it.it)
- XM reader now supports instrument vibrato 4, random. Yet another ModPlug
extension. (hcw-st.xm)
2006-05-21 02:11 UTC - kode54
- S3M reader correctly reads all 24 bits of the sample memory segment
offset, fixing at least one file with >1MB of sample data (d-t-x_x.s3m)
- XM reader stops reading instruments when it has at least one valid
instrument and encounters an error, fixing at least one file with
too high instrument count in the header (drx-chri.xm)
- IT reader ignores instrument header signatures, since there seem to
be files with bad signatures on unused/filler instruments (dsouls.it)
- MOD reader can now be restricted to handling 31 sample files with
legal/known signatures only, so frontend can fall back on restricted
MOD loading for files with incorrect extensions (dreamer_0g.s3m)
2006-05-20 xx:xx UTC - kode54
- Modified silence skipping to hack around some "S L O W" effects crap
and a misused break to row effect

Howto build libdumb with cmake
|
||||||
|
==============================
|
||||||
|
|
||||||
|
A quick example
|
||||||
|
---------------
|
||||||
|
|
||||||
|
In libdumb cmake directory (dumb/cmake/), run:
|
||||||
|
```
|
||||||
|
mkdir -p build
|
||||||
|
cd build
|
||||||
|
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local -DBUILD_SHARED_LIBS:BOOL=ON ..
|
||||||
|
make
|
||||||
|
make install
|
||||||
|
```
|
||||||
|
|
||||||
|
Steps
|
||||||
|
-----
|
||||||
|
|
||||||
|
1. Create a new temporary build directory and cd into it
|
||||||
|
2. Run libdumb cmake file with cmake (eg. `cmake -DCMAKE_INSTALL_PREFIX=/install/dir -DBUILD_SHARED_LIBS:BOOL=OFF -DCMAKE_BUILD_TYPE=Release path/to/dumb/cmake/dir`).
|
||||||
|
3. Run make (eg. just `make` or `mingw32-make` or something).
|
||||||
|
4. If needed, run make install.
|
||||||
|
|
||||||
|
Flags
|
||||||
|
-----
|
||||||
|
|
||||||
|
* CMAKE_INSTALL_PREFIX sets the installation path prefix
|
||||||
|
* CMAKE_BUILD_TYPE sets the build type (eg. Release, Debug, RelWithDebInfo, MinSizeRel). 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" .`.

*** How the functions have been deprecated ***
|
|
||||||
**********************************************
|
|
||||||
|
|
||||||
|
|
||||||
GCC 3.1 and later provide a very useful attribute. The following:
|
|
||||||
|
|
||||||
__attribute__((__deprecated__))
|
|
||||||
|
|
||||||
when written alongside a function prototype, variable declaration or type
|
|
||||||
definition, will result in a warning from GCC if any such part of the API
|
|
||||||
is used. The warning will even tell you where the declaration is, and I
|
|
||||||
have inserted comments by all the deprecated declarations, telling you
|
|
||||||
what to do.
|
|
||||||
|
|
||||||
Unfortunately, GCC 2.x and 3.0.x and MSVC do not have any means to
|
|
||||||
deprecate things. The approach I have taken with these compilers is to
|
|
||||||
avoid prototyping the deprecated parts of the API. This means you will get
|
|
||||||
warnings and errors, and they won't be very helpful. If your program
|
|
||||||
compiles, you may get strange crashes when you run it, since the compiler
|
|
||||||
needs the declarations in order to make sure function calls are carried
|
|
||||||
out correctly.
|
|
||||||
|
|
||||||
If you would like the deprecated parts of the API to be declared, you can
|
|
||||||
compile with the -DDUMB_DECLARE_DEPRECATED switch for GCC, or the
|
|
||||||
-D"DUMB_DECLARE_DEPRECATED" switch for MSVC. This will be accepted by
|
|
||||||
GCC 3.x but is unnecessary. Use this switch with other people's projects
|
|
||||||
if necessary, but please make the effort to update your own projects to
|
|
||||||
use the new API, as the deprecated parts may be removed in the future.
|
|
||||||
|
|
||||||
The rest of this file explains why some parts of the API were deprecated,
|
|
||||||
and how to adapt your code.

*** What happened to DUH_RENDERER? ***
|
|
||||||
**************************************
|
|
||||||
|
|
||||||
|
|
||||||
The DUH_RENDERER struct was designed for rendering audio to an end-user
|
|
||||||
format - 8-bit or 16-bit, signed or unsigned, with stereo samples
|
|
||||||
interleaved. In order for it to do this, it was built on top of the
|
|
||||||
hitherto undocumented DUH_SIGRENDERER struct, which rendered audio in
|
|
||||||
DUMB's internal 32-bit signed format with channels (left/right) stored
|
|
||||||
separately. The DUH_RENDERER struct contained a pointer to a
|
|
||||||
DUH_SIGRENDERER struct, along with some other data like the position and
|
|
||||||
number of channels.
|
|
||||||
|
|
||||||
There were then some developments in the API. The DUH_SIGRENDERER struct
|
|
||||||
also stored the position and the number of channels, so I decided to write
|
|
||||||
functions for returning these. Suddenly there was no need to store them in
|
|
||||||
the DUH_RENDERER struct. Before long, the DUH_RENDERER struct contained
|
|
||||||
nothing but a pointer to a DUH_SIGRENDERER.
|
|
||||||
|
|
||||||
I decided it would be a good idea to unify the structs. After all, there
|
|
||||||
really is no difference between the data stored in each, and it would be
|
|
||||||
easy to make duh_render(DUH_RENDERER *dr, ...) and
|
|
||||||
duh_render_signal(DUH_SIGRENDERER *sr, ...) work on the same type of
|
|
||||||
struct. (Note that duh_render_signal() is now deprecated too; see the next
|
|
||||||
section.) It took some deliberation, but I decided I didn't want functions
|
|
||||||
to be #defined (it prevents you from using these names for member
|
|
||||||
functions in C++ classes), and that meant they had to be defined
|
|
||||||
somewhere. Defining redundant functions is a source of bloat, inefficiency
|
|
||||||
and general inelegance. After weighing things up, I decided it was better
|
|
||||||
to deprecate the redundant functions and have people begin to use the more
|
|
||||||
efficient versions, and eventually the redundant functions will be able to
|
|
||||||
be removed.
|
|
||||||
|
|
||||||
So why did I choose to keep the more complicated name, DUH_SIGRENDERER?
|
|
||||||
The reason has to do with what DUMB will become in the future. Signals are
|
|
||||||
an inherent part of the DUH struct and how .duh files will be constructed.
|
|
||||||
It will be possible to have multiple signals in a single DUH struct, and
|
|
||||||
you will be able to choose which one you want to play (this is the 'sig'
|
|
||||||
parameter passed to duh_start_sigrenderer()). But don't hold your breath;
|
|
||||||
we still have a long way to go before .duh files will start to appear...
|
|
||||||
|
|
||||||
|
|
||||||
typedef DUH_SIGRENDERER DUH_RENDERER;
|
|
||||||
|
|
||||||
Wherever you are using DUH_RENDERER in your program, simply replace it
|
|
||||||
with DUH_SIGRENDERER. An automated (case-sensitive!) search and replace
|
|
||||||
operation should get this done.
|
|
||||||
|
|
||||||
|
|
||||||
DUH_RENDERER *duh_start_renderer(DUH *duh, int n_channels, long pos);
|
|
||||||
|
|
||||||
Use duh_start_sigrenderer() instead. It takes an extra parameter, 'sig',
|
|
||||||
which comes after 'duh' and before 'n_channels'; pass 0 for this. So an
|
|
||||||
example would be, replace:
|
|
||||||
|
|
||||||
sr = duh_start_renderer(duh, 2, 0);
|
|
||||||
|
|
||||||
with:
|
|
||||||
|
|
||||||
sr = duh_start_sigrenderer(duh, 0, 2, 0);
|
|
||||||
|
|
||||||
|
|
||||||
int duh_renderer_get_n_channels(DUH_RENDERER *dr);
|
|
||||||
long duh_renderer_get_position(DUH_RENDERER *dr);
|
|
||||||
void duh_end_renderer(DUH_RENDERER *dr);
|
|
||||||
|
|
||||||
These are easy enough to fix; all you have to do is replace 'renderer'
|
|
||||||
with 'sigrenderer'. So the new functions are:
|
|
||||||
|
|
||||||
int duh_sigrenderer_get_n_channels(DUH_SIGRENDERER *sigrenderer);
|
|
||||||
long duh_sigrenderer_get_position(DUH_SIGRENDERER *sigrenderer);
|
|
||||||
void duh_end_sigrenderer(DUH_SIGRENDERER *sigrenderer);
|
|
||||||
|
|
||||||
|
|
||||||
Note that duh_render() has NOT been deprecated. It now uses DUH_SIGRENDERER
|
|
||||||
instead of DUH_RENDERER, but its functionality is unchanged. You do not have
|
|
||||||
to change calls to this function in any way.
|
|
||||||
|
|
||||||
|
|
||||||
DUH_RENDERER *duh_renderer_encapsulate_sigrenderer(DUH_SIGRENDERER *sr);
|
|
||||||
DUH_SIGRENDERER *duh_renderer_get_sigrenderer(DUH_RENDERER *dr);
|
|
||||||
DUH_SIGRENDERER *duh_renderer_decompose_to_sigrenderer(DUH_RENDERER *dr);
|
|
||||||
|
|
||||||
These functions did not exist in the last release of DUMB, so you are
|
|
||||||
probably not using them, but they are included here for completeness. All
|
|
||||||
you have to do here is unwrap the function, since the structs have been
|
|
||||||
unified. So, for instance, replace:
|
|
||||||
|
|
||||||
duh_renderer_encapsulate_sigrenderer(my_sigrenderer)
|
|
||||||
|
|
||||||
with:
|
|
||||||
|
|
||||||
my_sigrenderer
|
|
||||||
|
|
||||||
Simple!
|
|
||||||
|
|
||||||
|
|
||||||
AL_DUH_PLAYER *al_duh_encapsulate_renderer(DUH_RENDERER *dr,
|
|
||||||
float volume, long bufsize, int freq);
|
|
||||||
DUH_RENDERER *al_duh_get_renderer(AL_DUH_PLAYER *dp);
|
|
||||||
DUH_RENDERER *al_duh_decompose_to_renderer(AL_DUH_PLAYER *dp);
|
|
||||||
|
|
||||||
Again, these functions were not in the last release, so you probably
|
|
||||||
aren't using them. Nevertheless, the fix is simple as always: simply
|
|
||||||
replace 'renderer' with 'sigrenderer'. So the new functions are:
|
|
||||||
|
|
||||||
AL_DUH_PLAYER *al_duh_encapsulate_sigrenderer(DUH_SIGRENDERER *sr,
|
|
||||||
float volume, long bufsize, int freq);
|
|
||||||
DUH_SIGRENDERER *al_duh_get_sigrenderer(AL_DUH_PLAYER *dp);
|
|
||||||
DUH_SIGRENDERER *al_duh_decompose_to_sigrenderer(AL_DUH_PLAYER *dp);
|
|
||||||
|
|
||||||

|
||||||
|
|

|
|
||||||
long duh_render_signal(DUH_SIGRENDERER *sigrenderer,
|
|
||||||
float volume, float delta,
|
|
||||||
long size, sample_t **samples);
|
|
||||||
|
|
||||||
This function used to return samples in DUMB's internal format. This
|
|
||||||
format consisted of 32-bit integers whose 'normal range' was -0x8000 to
|
|
||||||
0x7FFF (any samples outside this range would have to be clipped when sent
|
|
||||||
to the sound card).
|
|
||||||
|
|
||||||
DUMB's internal format has changed. DUMB still uses 32-bit integers, but
|
|
||||||
now the normal range is -0x800000 to 0x7FFFFF. The lowest eight bits are
|
|
||||||
discarded at the final stage by duh_render() when you ask for 16-bit
|
|
||||||
output. A new function, duh_sigrenderer_get_samples(), will return samples
|
|
||||||
in DUMB's new internal format. It takes exactly the same parameters, so
|
|
||||||
all you have to do to the call itself is change the name; however, you
|
|
||||||
will most likely have to change your code to account for the new
|
|
||||||
normalised range.
|
|
||||||
|
|
||||||
duh_render_signal() will still be able to give you the samples in DUMB's
|
|
||||||
old internal format, but it is inefficient. You should change your code as
|
|
||||||
soon as possible.
|
|
||||||

|
|
||||||
typedef void (*DUH_SIGRENDERER_CALLBACK)(void *data, sample_t **samples,
|
|
||||||
int n_channels, long length);
|
|
||||||
|
|
||||||
void duh_sigrenderer_set_callback(DUH_SIGRENDERER *sigrenderer,
|
|
||||||
DUH_SIGRENDERER_CALLBACK callback, void *data);
|
|
||||||
|
|
||||||
This callback was intended to allow you to analyse the output. It was by
|
|
||||||
no means intended to let you modify the output. For this reason, the names
|
|
||||||
have been changed to DUH_SIGRENDERER_ANALYSER_CALLBACK and
|
|
||||||
duh_sigrenderer_set_analyser_callback, and the 'samples' parameter to your
|
|
||||||
callback should now be specified as follows:
|
|
||||||
|
|
||||||
const sample_t *const *samples
|
|
||||||
|
|
||||||
The first 'const' indicates that you must not modify the samples. The
|
|
||||||
second indicates that you must not modify the pointers to each channel.
|
|
||||||
|
|
||||||
There is a second reason why this change was necessary, and it is the one
|
|
||||||
described further up for duh_render_signal()'s entry: the format in which
|
|
||||||
the samples themselves are stored has changed. They are 256 times as
|
|
||||||
large, with a normal range from -0x800000 to 0x7FFFFF. You will most
|
|
||||||
likely need to change your code to account for this.
|
|
||||||
|
|
||||||
If you try to call the old function, it will print a message to stderr
|
|
||||||
directing you to this file, and it will not install the callback. You
|
|
||||||
shouldn't be able to get this far without a compiler warning (or, if you
|
|
||||||
don't have GCC 3.1 or later, some compiler errors).
|
|
||||||
|
|
||||||
If you wanted to use this callback to apply a DSP effect, don't worry;
|
|
||||||
there is a better way of doing this. It is undocumented, so contact me
|
|
||||||
and I shall try to help. Contact details are at the bottom of this file.
|
|
||||||
|
|
||||||
For reference, here are the new definitions:
|
|
||||||
|
|
||||||
typedef void (*DUH_SIGRENDERER_ANALYSER_CALLBACK)(void *data,
|
|
||||||
const sample_t *const *samples, int n_channels, long length);
|
|
||||||
|
|
||||||
void duh_sigrenderer_set_analyser_callback(DUH_SIGRENDERER *sigrenderer,
|
|
||||||
DUH_SIGRENDERER_ANALYSER_CALLBACK callback, void *data);
|
|
||||||
|
|
||||||
|
|
||||||
int dumb_resampling_quality;
|
|
||||||
|
|
||||||
This variable has changed meaning. It used to hold a value from 0 to 4,
|
|
||||||
whose meaning was as follows:
|
|
||||||
|
|
||||||
0 - aliasing
|
|
||||||
1,2 - linear interpolation
|
|
||||||
3 - quadratic interpolation
|
|
||||||
4 - cubic interpolation
|
|
||||||
|
|
||||||
0,1 - always use a straightforward interpolation algorithm
|
|
||||||
2,3,4 - when decimating (increasing the pitch), use a linear average
|
|
||||||
algorithm designed to reduce frequencies that would otherwise
|
|
||||||
reflect off the Nyquist
|
|
||||||
|
|
||||||
Now the variable only holds values from 0 to 2, and these values have
|
|
||||||
preprocessor constants associated with them. The somewhat inappropriate
|
|
||||||
quadratic interpolation has been removed. The linear average algorithm has
|
|
||||||
also been removed, and may or may not come back; there are probably more
|
|
||||||
efficient ways of achieving the same effect, which I shall be
|
|
||||||
investigating in the future.
|
|
||||||
|
|
||||||
This change will have hardly any noticeable effect on existing programs.
|
|
||||||
Levels 2, 3 and 4 used considerably more processor time because of the
|
|
||||||
linear average algorithm. Likewise, Level 2 in the new scheme (cubic) uses
|
|
||||||
considerably more processor time than Levels 1 and 0, and Levels 3 and 4
|
|
||||||
will behave identically to Level 2.

Technical Details
|
|
||||||
=================
|
|
||||||
|
|
||||||
WARNING: until this warning disappears, the DUH file format could change at
|
|
||||||
any moment. This should not be of great concern, since DUH files are not
|
|
||||||
designed to be edited directly, but will always be generated from some other
|
|
||||||
format. However, it is our intention that this warning be removed before the
|
|
||||||
first release.
|
|
||||||
|
|
||||||
This document is written chiefly in the context of writing a DUH file, since
|
|
||||||
the library already contains the necessary functionality to read and play a
|
|
||||||
DUH file.
|
|
||||||
|
|
||||||
DUH files are currently saved using Allegro's file compression routines. See
|
|
||||||
Allegro's documentation and source code for details on this system. If you
|
|
||||||
wish to port DUMB away from Allegro and wish to preserve the file compression
|
|
||||||
capabilities, you will have to borrow the packfile source code from Allegro.
|
|
||||||
|
|
||||||
If you are happy to do away with file compression, please store the following
|
|
||||||
four-byte signature before the rest of the file: "slh." Alternatively, write
|
|
||||||
your DUH file writer with Allegro, and open the file with F_WRITE_NOPACK.
|
|
||||||
This will enable versions of the library using Allegro's file compression
|
|
||||||
routines to load the file. If you are reading a DUH file and you detect the
|
|
||||||
signature "slh!", then the file is compressed (and is not necessarily a DUH
|
|
||||||
file).
|
|
||||||
|
|
||||||
All numbers are little-endian unless specified otherwise. Allegro's
|
|
||||||
pack_iget*() and pack_iput*() functions can be used to read and write data in
|
|
||||||
this format. However, the four-byte signatures can be encoded into long ints
|
|
||||||
with AL_ID() and read and written with pack_m*().
|
|
||||||
|
|
||||||
|
|
||||||
Overall Structure

|

|
||||||
4 Int Number of signals pack_iputl(n_signals, f);
|
|

For each signal { for (i = 0; i < n_signals; i++) {

|
|
||||||
* - Signal data write_sequence(f);
|
|
||||||
} }
|
|
||||||
|
|
||||||
* The size of the data for any signal must either be constant or somehow
|
|
||||||
encoded in the data themselves. The library contains functions to read
|
|
||||||
various standard signal types, including "SAMP" and "SEQU" (sample and
|
|
||||||
sequence respectively), and the formats for these types are laid out
|
|
||||||
further down. If you wish to create your own signals, you must provide your
|
|
||||||
own loading function for the signal. This will be described in more detail
|
|
||||||
in a separate file.
|
|
||||||
|
|
||||||
In order to play a DUH file, we simply play the first signal. Signals can
|
|
||||||
construct their sound from the samples of other signals, and they in turn can
|
|
||||||
use other signals. Thus a recursive structure is built up. Recursive cycles
|
|
||||||
are not permitted.
|
|
||||||
|
|
||||||
|
|
||||||
Signal: SAMP (Sample)
|
|
||||||
=====================
|
|
||||||
|
|
||||||
Size Type Value Example C code to save to PACKFILE *f
|
|
||||||
|
|
||||||
4 Int Size pack_iputl(size, f);
|
|
||||||
1 Bits Flags pack_putc(flags, f);
|
|
||||||
1 ID Compression type pack_putc(compress, f); /* NOT IMPLEMENTED YET */
|
|
||||||
|
|
||||||
The flags are stored in a bit-field. Bit 0 indicates whether 16-bit samples
|
|
||||||
(set) or 8-bit samples (clear) are stored in the file. In both cases, the
|
|
||||||
samples are signed. NOTE: this bit might be replaced with a system allowing
|
|
||||||
for various sample compression algorithms, or altered so there are different
|
|
||||||
signal types for the purpose.
|
|
||||||
|
|
||||||
If Bit 1 is set, the sample is a looping sample, and loops indefinitely. In
|
|
||||||
this case the loop start point will be saved. The loop end point is not
|
|
||||||
saved, and is assumed to be the end of the sample. (When creating DUH files
|
|
||||||
from other formats which allow for the loop end to be earlier, you should
|
|
||||||
truncate the sample.)
|
|
||||||
|
|
||||||
If Bit 1 is not set, then Bit 2 may be set to indicate that the sample is
|
|
||||||
looping but only loops a finite number of times before continuing to play
|
|
||||||
normally. In this mode, both loop points (start and end) are saved in the
|
|
||||||
file. The number of times to loop will be specified on an instance-by-
|
|
||||||
instance basis using signal parameter #0, which should be set immediately
|
|
||||||
(before any samples are rendered) if it is to be set at all. It defaults to 0
|
|
||||||
(so the sample just plays through normally). In fact this parameter's value
|
|
||||||
is added to the loop count, but this is immaterial since there is no reason
|
|
||||||
to specify it more than once.
|
|
||||||
|
|
||||||
If Bit 1 is set, you should make sure Bit 2 is clear to allow for the
|
|
||||||
possibility of future expansion.
|
|
||||||
|
|
||||||
If Bit 3 is set, a ping-pong loop is used. When the sample reaches the loop
|
|
||||||
end point, it starts to play backwards until it reaches the loop start point,
|
|
||||||
at which time it will resume forward playback. When using a finite loop,
|
|
||||||
every change of direction counts as one iteration. That means an odd loop
|
|
||||||
count will cause the sample to proceed backwards when the looping ends.
|
|
||||||
|
|
||||||
If neither Bit 1 nor Bit 2 is set, then neither loop point will be saved. In
|
|
||||||
this case, you should also make sure Bit 3 is clear for the same reason as
|
|
||||||
above.
|
|
||||||
|
|
||||||

|
|

|
|
||||||

|
|
||||||
for (n = 0; n < size; n++)
|
|
||||||
x*1 Int Sample data pack_putc(sample[n], f);
|
|
||||||

|
||||||
Signal: SEQU (Sequence)
|
|
||||||
=======================
|
|
||||||
|
|
||||||
Size Type Value Example C code to save to PACKFILE *f
|
|
||||||
|
|
||||||
4 Int Size size = pack_igetl(f);
|
|
||||||
x - Sequencing data pack_fwrite(data, size, f);
|
|
||||||
|
|
||||||
The sequence signal provides a medium in which other signals can be played at
|
|
||||||
specific times for specific lengths. You can control the pitch, volume and
|
|
||||||
other parameters for a signal, and these can change during the signal.
|
|
||||||
|
|
||||||
A sequence consists of a series of commands. Each command is preceded by a
|
|
||||||
time, which measures how long to wait before executing this command. A time
|
|
||||||
of zero indicates that this command is simultaneous with the previous. A time
|
|
||||||
of -1 indicates the end of the sequence. Note that signals do not stop
|
|
||||||
playing when the end is reached.
|
|
||||||
|
|
||||||
All times are measured in units such that 65536 corresponds to one second.
|
|
||||||
The timing in DUMB is accurate to the nearest sample, and cannot be offset in
|
|
||||||
the way it can with much mixing software, so you can rely on timing to
|
|
||||||
achieve certain effects. Resampling should be accurate enough to satisfy the
|
|
||||||
most acute musician's ear, but juggling pitches at this level of accuracy
|
|
||||||
requires knowledge of temperaments such as many musicians do not have. The
|
|
||||||
vast majority of people are satisfied with the even temperament. More on this
|
|
||||||
later.

The value of 'time' is actually an unsigned offset from the time of the
|
|
||||||
previous command. 0 means at the same time as the last command.
|
|
||||||
If the time in between this signal and the previous one is larger than
|
|
||||||
65534 ticks, then the value 65535 is written, followed by 4 more bytes (uint)
|
|
||||||
indicating the time offset.

fields are explained afterwards.

4 Int Value pack_iputl(value, f);
|
|
||||||
|
|
||||||
SEQUENCE_STOP_SIGNAL:
|
|
||||||
1 ID Reference pack_putc(ref, f);
|
|
||||||
|
|
||||||
When you initiate a signal, you must choose a reference number. If you want
|
|
||||||
to modify the signal's volume, pitch or parameters, or stop the signal later,
|
|
||||||
you must use this reference number to do so. Need more than 256 reference
|
|
||||||
numbers? Use two sequences, and get your brain seen to.
|
|
||||||
|
|
||||||
If you initiate a new signal with the same reference number, the reference
|
|
||||||
will belong to the new signal. The old signal becomes anonymous, and will
|
|
||||||
either continue to play indefinitely or stop of its own accord. Even if the
|
|
||||||
new signal stops, the old one remains anonymous. DUMB will safely ignore
|
|
||||||
operations on reference numbers not used by any signal, or which were used by
|
|
||||||
a signal which has now stopped.
|
|
||||||
|
|
||||||
Of course all signals will stop if the sequence itself is stopped.
|
|
||||||
|
|
||||||
To initiate a signal, you must index the signal. The index is 0-based, so to
|
|
||||||
initiate the fifth signal in the file you must specify 4. Out-of-range values
|
|
||||||
will be handled safely, as will the case where a signal tries to generate
|
|
||||||
itself directly or indirectly from its own samples (a recursive cycle).
|
|
||||||
|
|
||||||
When you initiate a signal, you can specify a starting position. This will be
|
|
||||||
passed directly to the appropriate signal's start_samples function, so for a
|
|
||||||
SAMP (sample) signal it represents the sample on which to start, after any
|
|
||||||
loops have been expanded (so you can start on the backwards-playing part of
|
|
||||||
a ping-pong loop for example by careful choice of the starting position).
|
|
||||||
|
|
||||||
Volume is probably the simplest parameter. It is on a linear scale ranging
|
|
||||||
from 0 to 65535. Note that most music sounds more dramatic if the volume
|
|
||||||
rises and falls exponentially or on a greater curve. Linear fades are more
|
|
||||||
suitable for fading in and out, and do not sound dramatic in the least.
|
|
||||||
|
|
||||||
Pitch is specified on what is perceived as a linear scale. It is in fact
|
|
||||||
logarithmic, but you will not need to worry about this for most purposes.
|
|
||||||
Pitch 0 represents that the sample will be played at 65536 Hz. (This is not
|
|
||||||
strictly true, and will be explained further later.) In the likely case that
|
|
||||||
your sample is not recorded at 65536 Hz, you will first need to calculate the
|
|
||||||
central pitch. Use the following formula:
|
|
||||||
|
|
||||||
pitch_centre = 12 * 256 * log(sampling_frequency / 65536.0) / log(2);
|
|
||||||
|
|
||||||
If your programming language does not have a log function, look for ln, or
|
|
||||||
any function that calculates the logarithm (to any base) of the number you
|
|
||||||
give it. If you are lucky enough to find a logarithm to base 2, you can omit
|
|
||||||
the final division since the divisor evaluates to 1.
|
|
||||||
|
|
||||||
Once you have calculated pitch_centre, you can use it to play the sample at
|
|
||||||
the frequency at which it was recorded. Each time you add or subtract 256,
|
|
||||||
the sample will increase or decrease respectively in pitch by one semitone in
|
|
||||||
the even temperament. (The even temperament was noted further up as being
|
|
||||||
suitable for most musical applications.) One octave is represented by an
|
|
||||||
interval of 12 * 256.
|
|
||||||
|
|
||||||
If you wish to use another temperament, you can calculate the appropriate
|
|
||||||
intervals in pitch as follows:
|
|
||||||
|
|
||||||
pitch_interval = 12 * 256 * log(ratio) / log(2);
|
|
||||||
|
|
||||||
where, for example, ratio = 1.5 for a perfect fifth. An octave is, of course,
|
|
||||||
still represented by 12 * 256.
|
|
||||||
|
|
||||||
The SEQUENCE_SET_PARAMETER command needs little explanation. Quite simply,
|
|
||||||
the parameter ID and value you specify are passed on to the set_parameter
|
|
||||||
function of the signal to which this reference belongs. Exactly what this
|
|
||||||
does depends on the signal in question.
|
|
||||||
|

Remember, a sequence is a signal in itself. Like all signals, it is subject
|
|
||||||
to changes in pitch. Increasing the pitch of a sequence will also speed it
|
|
||||||
up. This capability is used to allow DUH files to be rendered at different
|
|
||||||
sampling frequencies, and it is also available for use by the musician. This
|
|
||||||
means that samples are only played at 65536 Hz if the pitch of the sequence
|
|
||||||
itself has not been adjusted.

|
|
||||||
* I get a lot of strange warnings and errors when I compile my projects *
|
|
||||||
* with this release of DUMB. They work with older versions! What happened? *
|
|
||||||
*****************************************************************************
|
|
||||||
|
|
||||||
Some parts of DUMB's API have been deprecated. See docs/deprec.txt for
|
|
||||||
full details, including an explanation as to why your compiler warnings
|
|
||||||
and errors are so unfriendly, and information on how to fix each warning
|
|
||||||
or error.
|
|
||||||
|
|
||||||
|
|
||||||
*****************************************************************************
|
|
||||||
* When I try to compile DUMB with Allegro, it complains that it cannot find *
|
|
||||||
* 'internal/alconfig.h'! What's wrong? *
|
|
||||||
*****************************************************************************
|
|
||||||
|
|
||||||
In Allegro 4.0.1, and quite likely some other versions of Allegro, the
|
|
||||||
msvcmake batch file does not install Allegro properly. I believe this was
|
|
||||||
fixed in Allegro 4.0.2, but don't take my word for it. Some include files
|
|
||||||
are neglected, including alconfig.h. The fix is quite easy; you need to
|
|
||||||
copy all of Allegro's include files to your compiler's directory. The
|
|
||||||
following should do this for you (alter it accordingly depending on where
|
|
||||||
MSVC and Allegro are installed):
|
|
||||||
|
|
||||||
cd\progra~1\msvc\include
|
|
||||||
xcopy/s \allegro\include\*.*
|
|
||||||
|
|
||||||
You can safely tell it to overwrite all files.
|
|
||||||
|
|
||||||
|
|
||||||
*****************************************************************************
|
|
||||||
* When I build a project that uses DUMB, I get an error that it doesn't *
|
|
||||||
* find -laldmbd! What's wrong? *
|
|
||||||
*****************************************************************************
|
|
||||||
|
|
||||||
See the notes for DUMB v0.8 in release.txt; the existence of libaldmbd.a
|
|
||||||
in DUMB v0.7 was due to a mistake in the makefiles. It should be
|
|
||||||
libaldmd.a, in order to maintain DOS compatibility. All subsequent
|
|
||||||
releases get it right, but you will have to change your project files to
|
|
||||||
allow for the change. If this is someone else's project, please let them
|
|
||||||
know that it needs changing.
|
|
||||||
|
|
||||||
|
|
||||||
*****************************************************************************
|
|
||||||
* When I build a project that uses DUMB, I get some linker errors about *
|
|
||||||
* _free, _malloc, etc. already being defined in LIBC.lib! What's wrong? *
|
|
||||||
*****************************************************************************
|
|
||||||
|
|
||||||
MSVC offers three different implementations of the standard libraries.
|
|
||||||
When you link statically with a library, you have to use the same
|
|
||||||
implementation that the library uses. You need the multithreaded DLL
|
|
||||||
implementation, which you can select by passing /MD when you compile (not
|
|
||||||
when you link). See howto.txt for details.
|
|
||||||
|
|
||||||
|
|
||||||
*****************************************************************************
|
|
||||||
* I created an IT file with Impulse Tracker, but DUMB won't play it! Why? *
|
|
||||||
*****************************************************************************
|
|
||||||
|
|
||||||
You probably created some patterns but didn't give any information on the
|
|
||||||
order in which they should be played. Impulse Tracker will also fail to
|
|
||||||
play your music if you press F5. Press F11 and you will have an
|
|
||||||
opportunity to create an order list, required for playback.
|
|
||||||
|
|
||||||
|
|
||||||
*****************************************************************************
|
|
||||||
* I created an IT file with ModPlug Tracker and I have it fading out at the *
|
|
||||||
* end. Why won't it loop when I play it with DUMB? *
|
|
||||||
*****************************************************************************
|
|
||||||
|
|
||||||
It loops at zero volume. This is what Impulse Tracker itself does. Fix the
|
|
||||||
IT file by setting the global volume explicitly (Vxx in the effects
|
|
||||||
column), either at the start, or right at the end before looping. Also see
|
|
||||||
the next two questions.
|
|
||||||
|
|
||||||
|
|
||||||
*****************************************************************************
|
|
||||||
* My module plays too loud and distorts badly with DUMB! What can I do? *
|
|
||||||
*****************************************************************************
|
|
||||||
|
|
||||||
This problem is most often caused by ModPlug Tracker, which has a complete
|
|
||||||
lack of regard for the playback volume of the original tracker. See the
|
|
||||||
next question for DUMB's official position with regard to ModPlug Tracker.
|
|
||||||
If you wrote your module with ModPlug Tracker, please try loading it with
|
|
||||||
the original tracker and see if it distorts there too. If it does, reduce
|
|
||||||
the volume. If not, then it's a problem with DUMB; please let me know.
|
|
||||||
|
|
||||||
If for whatever reason you cannot modify the module file itself, you can
|
|
||||||
make it sound better by reducing the volume passed to al_start_duh().
|
|
||||||
|
|
||||||
|
|
||||||
*****************************************************************************
|
|
||||||
* I created a music module with ModPlug Tracker, and DUMB doesn't play it *
|
|
||||||
* right! *
|
|
||||||
*****************************************************************************
|
|
||||||
|
|
||||||
DUMB cannot and will not support ModPlug Tracker. Please see
|
|
||||||
docs/modplug.txt for details. The original trackers, which DUMB is
|
|
||||||
designed to mimic as closely as possible, are listed in readme.txt.
|
|
||||||
If you find DUMB plays your module differently from the original tracker,
|
|
||||||
then please contact me.
|
|
||||||
|
|
||||||
|
|
||||||
*****************************************************************************
|
|
||||||
* My program crashes as soon as I try to load anything with DUMB! *
|
|
||||||
*****************************************************************************
|
|
||||||
|
|
||||||
Please take my advice and use the debugging build of DUMB, not the
|
|
||||||
optimised build. Then you'll probably find it aborts instead of crashing.
|
|
||||||
In this case you probably forgot to register a DUMBFILE system; this is
|
|
||||||
necessary for loading stand-alone files, though not for loading Allegro
|
|
||||||
datafiles with embedded music. Follow the instructions in docs/howto.txt
|
|
||||||
carefully and you shouldn't have this problem.
|
|
||||||
|
|
||||||
If DUMB crashes with a specific music module, please let me know.
|
|
||||||
|
|
||||||
|
|
||||||
*****************************************************************************
|
|
||||||
* I want to use the stdio file access functions to load stand-alone music *
|
|
||||||
* files, but I also want to load datafiles containing music files. The docs *
|
|
||||||
* say I shouldn't call both dumb_register_stdfiles() and *
|
|
||||||
* dumb_register_packfiles(). What shall I do? *
|
|
||||||
*****************************************************************************
|
|
||||||
|
|
||||||
When you register a DUMBFILE system, it only applies to files opened with
|
|
||||||
dumbfile_open(), i.e. separate files. When a file is embedded in a
|
|
||||||
datafile, dumbfile_open_ex() is used to read it, enabling it to use
|
|
||||||
PACKFILEs regardless of which DUMBFILE system is registered. In short, you
|
|
||||||
do not need to call dumb_register_packfiles() in order to load datafiles
|
|
||||||
with embedded music. See the section on "Sequential File Input" in
|
|
||||||
docs/dumb.txt if you're interested in how all this works.
|
|
||||||
|
|
||||||
|
|
||||||
*****************************************************************************
|
|
||||||
* I want to read a specific object in a datafile using Allegro's *
|
|
||||||
* "demo.dat#MY_MUSIC" syntax. Why won't it work? *
|
|
||||||
*****************************************************************************
|
|
||||||
|
|
||||||
Did you call dumb_register_packfiles(), or did you call
|
|
||||||
dumb_register_stdfiles()? It will only work if you use the former.
|
|
||||||
|
|
||||||
|
|
||||||
*****************************************************************************
|
|
||||||
* My program runs, but no music plays! What am I doing wrong? *
|
|
||||||
*****************************************************************************
|
|
||||||
|
|
||||||
There are a number of possible causes for this. The most likely reason is
|
|
||||||
that you aren't calling al_poll_duh(); see docs/howto.txt for further
|
|
||||||
information.
|
|
||||||
|
|
||||||
Other possible causes are as follows:
|
|
||||||
|
|
||||||
- The speakers are turned down (duh)
|
|
||||||
- The volume of some system mixer is turned down
|
|
||||||
- Another program is using the sound card (not a problem for most modern
|
|
||||||
systems)
|
|
||||||
- You didn't initialise Allegro's sound system; see install_sound() in
|
|
||||||
Allegro's docs
|
|
||||||
- Allegro's drivers don't work on your system and chosen platform
|
|
||||||
|
|
||||||
In order to narrow down the cause, consider the following:
|
|
||||||
|
|
||||||
- Do you get any other sound from your program?
|
|
||||||
- Do other Allegro+DUMB programs generate sound?
|
|
||||||
- Do other Allegro programs generate sound?
|
|
||||||
- Do other non-Allegro programs generate sound?
|
|
||||||
- Does your program fail only on a specific platform (e.g. DOS but not
|
|
||||||
Windows)?
|
|
||||||
|
|
||||||
This problem is highly system-specific; please try hard to solve it by
|
|
||||||
yourself before contacting me. However, if you think this problem could
|
|
||||||
affect other people, please let me know what the problem is and how you
|
|
||||||
fixed it, if you did. Be as specific as possible.
|
|
||||||

|

* The music stutters! What can I do? *
|
|
||||||
*****************************************************************************
|
|
||||||
|
|
||||||
If you have an older computer, it may not be able to cope with the load.
|
|
||||||
Try reducing quality options; look up dumb_resampling_quality and
|
|
||||||
dumb_it_max_to_mix in docs/dumb.txt, and consider changing the frequency
|
|
||||||
you pass to al_start_duh().
|
|
||||||
|
|
||||||
Stuttering may not be caused by excessive load. To find out, try
|
|
||||||
increasing the buffer size passed to al_start_duh(). Beware of making it
|
|
||||||
too big though; older systems will freeze periodically if it's too big,
|
|
||||||
because they render larger chunks less frequently. The timing of callbacks
|
|
||||||
will also be less accurate, if you are using those.
|
|
||||||
|
|
||||||
If you're using the 'dumbplay' example, you can control these parameters
|
|
||||||
by editing dumb.ini.
|
|
||||||
|
|
||||||
|
|
||||||
*****************************************************************************
|
|
||||||
* Why does DUMB use so much processor time compared with other players? *
|
|
||||||
*****************************************************************************
|
|
||||||
|
|
||||||
This should be less so in this release than in previous releases; the
|
|
||||||
resampling and filtering algorithms have been optimised.
|
|
||||||
|
|
||||||
By default, DUMB uses the most expensive resampling quality option. I've
|
|
||||||
found on an AthlonXP 1800+ and on a Pentium 233 that it typically uses
|
|
||||||
about twice as much processor time as the least expensive option.
|
|
||||||
|
|
||||||
Try setting dumb_resampling_quality to DUMB_RQ_ALIASING or DUMB_RQ_LINEAR.
|
|
||||||
See dumb.txt for more information. If you're using the example programs,
|
|
||||||
you can control this variable by editing dumb.ini.
|
|
||||||
|
|
||||||
DUMB uses 32-bit ints for mixing. Some players use 16-bit ints, and are
|
|
||||||
therefore marginally faster (not much!) and lower quality. So you can't
|
|
||||||
expect DUMB to beat these players. Furthermore, DUMB is currently written
|
|
||||||
entirely in C. GCC does an impressive job on the C code, but that's not to
|
|
||||||
say some custom-written assembly language couldn't beat it ...
|
|
||||||
|
|
||||||
|
|
||||||
*****************************************************************************
|
|
||||||
* Why does DUMB generate so much background noise? *
|
|
||||||
*****************************************************************************
|
|
||||||
|
|
||||||
You're probably using the DOS build on a system with bad Sound Blaster
|
|
||||||
compatibility (most Windows XP systems fall in this category). This would
|
|
||||||
mean DUMB could only access an 8-bit driver. The Windows build will almost
|
|
||||||
certainly give better results. Your DOS binary will still give good
|
|
||||||
results on systems with better compatibility (like my Windows 98 system).
|
|
||||||
|
|
||||||
|
|
||||||
*****************************************************************************
|
|
||||||
* I e-mailed you and you replied with "RTFM"! What does that mean? *
|
|
||||||
*****************************************************************************
|
|
||||||
|
|
||||||
Read The Manual. If it's a specific problem, I'll probably be kind and
|
|
||||||
tell you where to look in the manual. However, if I get the impression you
|
|
||||||
haven't even looked for a solution in the manual, expect no mercy ...

|
||||||

|
||||||
C allows you to create and use function pointers. A function pointer is a
|
|
||||||
variable that points to a function, and you can use it to call that function.
|
|
||||||
Why is this useful?
|
|
||||||
|
|
||||||
Function pointers can be passed as parameters. As an example, here's a
|
|
||||||
function from Allegro:
|
|
||||||
|
|
||||||
void create_light_table(COLOR_MAP *table, const PALETTE pal, int r, g, b,
|
|
||||||
void (*callback)(int pos));
|
|
||||||
|
|
||||||
Don't worry about the syntax just yet, but the last parameter, 'callback', is
|
|
||||||
a pointer to a function that takes an int parameter. create_light_table() can
|
|
||||||
take some time to complete its work, and you may want to display a progress
|
|
||||||
indicator. So you write a function to draw the progress indicator, and then,
|
|
||||||
for 'callback', you specify a pointer to your function. This will enable
|
|
||||||
create_light_table() to call your function at intervals during its
|
|
||||||
processing. (If you don't want to use the callback, you can pass NULL, but
|
|
||||||
this only works because create_light_table() checks actively for NULL. You
|
|
||||||
can't always specify NULL when you want nothing to happen.)
|
|
||||||
|
|
||||||
There are many other uses. In addition to using function pointers as
|
|
||||||
parameters, Allegro has some global function pointers you can set to point to
|
|
||||||
your functions. Function pointers can also be used in structs, and this is
|
|
||||||
where DUMB makes the most use of them.
|
|
||||||
|
|
||||||
So how are they used?
|
|
||||||
|
|
||||||
void bar(void) { ... } /* Here's a function */
|
|
||||||
void (*foo)(void) = &bar; /* Take a pointer */
|
|
||||||
(*foo)(); /* Call the function */
|
|
||||||
|
|
||||||
char *baz(float a) { ... } /* Here's another function */
|
|
||||||
char *(*foobarbaz)(float a) = &baz; /* Take a pointer */
|
|
||||||
char *rv = (*foobarbaz)(0.1); /* Call the function */
|
|
||||||
|
|
||||||
In both these cases, note how the statement for calling the pointed-to
|
|
||||||
function (third line) resembles the definition of the function pointer
|
|
||||||
(second line). This is true of any variable in C, and can lead to some truly
|
|
||||||
obfuscated definitions if you are that way inclined. Such definitions can be
|
|
||||||
clarified with typedefs, but before you use those, it is important you
|
|
||||||
understand how the above statements work. I speak from experience: function
|
|
||||||
pointer notation looks random and scary, until you understand why it's the
|
|
||||||
way it is; then it makes perfect sense.
|
|
||||||
|
|
||||||
(It is actually permissible to omit the & when taking a pointer and to write
|
|
||||||
e.g. foobarbaz(0.1) instead of (*foobarbaz)(0.1). However, I recommend not
|
|
||||||
doing this, since the syntax for using the pointer no longer resembles the
|
|
||||||
definition. Writing e.g. (*foobarbaz)(0.1) also makes a clear distinction
|
|
||||||
between function pointer calls and ordinary function calls, which makes code
|
|
||||||
more readable.)
|
|
||||||
|
|
||||||
Note that function pointers have the return value and parameter list
|
|
||||||
specified. A function pointer can only point to a function with a matching
|
|
||||||
return value and matching parameters. (You can break this rule by casting the
|
|
||||||
pointer explicitly, but there is no situation where doing so is portable to
|
|
||||||
all computers, and I strongly advise against it unless you're writing system
|
|
||||||
code. If you're not sure whether you're writing system code or not, then
|
|
||||||
you're not.)
|
|
||||||
|
|
||||||
The parameter names need not match (although the types must). If you wish to
|
|
||||||
rename a parameter in your function, you do not have to change the function
|
|
||||||
pointer accordingly. In fact, when you define a function pointer, you don't
|
|
||||||
even have to specify the names of parameters if you don't want to. I normally
|
|
||||||
do so for clarity.
|
|
||||||
|
|
||||||
It is possible to typedef a function pointer. In order to typedef a function
|
|
||||||
pointer, you start by declaring the pointer as a variable:
|
|
||||||
|
|
||||||
void (*myfunc)(void);
|
|
||||||
|
|
||||||
Then you write 'typedef' before it and replace the variable name, which is
|
|
||||||
myfunc, with the type name (this rule can be applied to any variable when you
|
|
||||||
want to use typedef):
|
|
||||||
|
|
||||||
typedef void (*MYTYPE)(void);
|
|
||||||
|
|
||||||
Now 'MYTYPE' represents a pointer to a function with no parameters and no
|
|
||||||
return value. The following two lines are completely equivalent:
|
|
||||||
|
|
||||||
MYTYPE myfunc;
|
|
||||||
void (*myfunc)(void);
|
|
||||||
|
|
||||||
Note that we use MYTYPE without an asterisk (*), since it is already a
|
|
||||||
pointer.
|
|
||||||
|
|
||||||
That's it. If you feel anything should be explained better here, or if you
|

*** Introduction ***
|
|
||||||
********************
|
|
||||||
|
|
||||||
|
|
||||||
Welcome to the DUMB How-To! It is assumed here that you have already set DUMB
|
|
||||||
up on your system, with or without Allegro. If not, please see readme.txt.
|
|
||||||
|
|
||||||
|
|
||||||
*********************************
|
|
||||||
*** Adding music to your game ***
|
|
||||||
*********************************
|
|
||||||
|
|
||||||
|
|
||||||
These instructions will help you add a piece of music to your game, assuming
|
|
||||||
your music is stored in a stand-alone IT, XM, S3M or MOD file. If you wish to
|
|
||||||
use a different method (such as putting the music file in an Allegro
|
|
||||||
datafile), please follow these instructions first, test your program, and
|
|
||||||
then follow the instructions further down for adapting your code.
|
|
||||||
|
|
||||||
|
|
||||||
1. You need to include DUMB's header file. If you have Allegro, add the
|
|
||||||
following line to the top of your source file (or at the top of each file
|
|
||||||
where you wish to use DUMB):
|
|
||||||
|
|
||||||
#include <aldumb.h>
|
|
||||||
|
|
||||||
If you do not have Allegro or do not wish to use it, use dumb.h instead.
|
|
||||||
|
|
||||||
|
|
||||||
2. You need to link with DUMB's library file or files. If you are compiling
|
|
||||||
with GCC from a command line on any platform, you need to add the
|
|
||||||
following to the command line:
|
|
||||||
|
|
||||||
If you are using Allegro: -laldmd -ldumbd
|
|
||||||
If you are not using Allegro: -ldumbd
|
|
||||||
|
|
||||||
If you are using MSVC from the command line:
|
|
||||||
|
|
||||||
If you are using Allegro: /link aldmd.lib dumbd.lib
|
|
||||||
If you are not using Allegro: /link dumbd.lib
|
|
||||||
|
|
||||||
With MSVC, you must also add /MD to the command line when compiling (not
|
|
||||||
when linking).
|
|
||||||
|
|
||||||
Note that -laldmd or aldmd.lib must PRECEDE alleg.lib, -lalleg_s,
|
|
||||||
`allegro-config --libs`, or whatever you are already using to link with
|
|
||||||
Allegro. For MSVC users, the /MD flag selects the multithreaded DLL
|
|
||||||
implementation of the standard libraries; since DUMB is statically linked,
|
|
||||||
you have to use the same library DUMB uses. You would also need this flag
|
|
||||||
to link statically with Allegro; if you already have it, there's no need
|
|
||||||
to put it twice.
|
|
||||||
|
|
||||||
(If anyone would like to contribute instructions for doing the above using
|
|
||||||
MSVC's IDE, please contact me. Contact details are at the end of this
|
|
||||||
file.)
|
|
||||||
|
|
||||||
If you are using RHIDE, go to Options -> Libraries. You will need to type
|
|
||||||
'aldmd' and 'dumbd' in two boxes, making sure 'aldmd' comes above whatever
|
|
||||||
you are using to link with Allegro (or just put 'dumbd' if you are not
|
|
||||||
using Allegro). Make sure the box next to each of these libraries is
|
|
||||||
checked.
|
|
||||||
|
|
||||||
The above are the debugging libraries. It is VERY HIGHLY RECOMMENDED that
|
|
||||||
you use the debugging libraries at first. The reason is as follows.
|
|
||||||
Although DUMB is supposedly robust against corrupt music files and things
|
|
||||||
like lack of memory, it will NOT tolerate programmer error. If you write
|
|
||||||
faulty code, DUMB will probably crash rather than returning an error code
|
|
||||||
for you. However, the debugging libraries will abort in many cases,
|
|
||||||
enabling you to find out what the cause is.
|
|
||||||
|
|
||||||
Once your program is up and running reliably, you can replace 'aldmd' with
|
|
||||||
'aldmb' and 'dumbd' with 'dumb'. Don't forget to do this, or DUMB will be
|
|
||||||
a lot slower than it should be!
|
|
||||||
|
|
||||||
|
|
||||||
3. As you use DUMB, it may claim system resources (memory in particular). You
|
|
||||||
will need to arrange for these resources to be freed at the end. Doing so
|
|
||||||
is very easy. Simply write the following line at the top of your main
|
|
||||||
function, but below allegro_init() if you are using Allegro:
|
|
||||||
|
|
||||||
atexit(&dumb_exit);
|
|
||||||
|
|
||||||
This arranges for the function dumb_exit() to be called when your program
|
|
||||||
exits; you do not need to call dumb_exit() yourself. This method is
|
|
||||||
preferable to calling dumb_exit() manually, as it will free resources even
|
|
||||||
if your program aborts unexpectedly.
|
|
||||||
|
|
||||||
If you are happy with this, please skip ahead to Step 4. If you are
|
|
||||||
interested in alternative methods, read on, but read on carefully.
|
|
||||||
|
|
||||||
In fact it mostly doesn't matter where you put the above atexit() line,
|
|
||||||
provided it gets called only once, and before you do anything with DUMB.
|
|
||||||
If you are using DUMB with Allegro, it is recommended that you write the
|
|
||||||
functions in this order:
|
|
||||||
|
|
||||||
allegro_init();
|
|
||||||
atexit(&dumb_exit);
|
|
||||||
|
|
||||||
And then you must NOT call allegro_exit() yourself (because it has to be
|
|
||||||
called after dumb_exit()). Alternatively, if you prefer not to use
|
|
||||||
atexit() (or you cannot), you will have to do the following before
|
|
||||||
exiting:
|
|
||||||
|
|
||||||
dumb_exit();
|
|
||||||
allegro_exit();
|
|
||||||
|
|
||||||
|
|
||||||
4. DUMB does not automatically do any of its own file input. You have to tell
|
|
||||||
it how to read files. Don't worry, it's easy. Simply call the following
|
|
||||||
function near the beginning of your program, after your atexit() call:
|
|
||||||
|
|
||||||
dumb_register_stdfiles();
|
|
||||||
|
|
||||||
This tells DUMB to use ordinary stdio FILE structs for reading and writing
|
|
||||||
files. If you are using Allegro and would rather DUMB used PACKFILEs, call
|
|
||||||
the following function INSTEAD:
|
|
||||||
|
|
||||||
dumb_register_packfiles();
|
|
||||||
|
|
||||||
In the latter case, DUMB will be affected by any password you set with
|
|
||||||
packfile_password() in the same way that other PACKFILEs are.
|
|
||||||
|
|
||||||
Note that the procedure for loading datafiles with embedded music is
|
|
||||||
independent of these two functions; even if you will be loading datafiles,
|
|
||||||
you can use either of these functions. If you are loading datafiles, your
|
|
||||||
executable might be slightly smaller if you use dumb_register_packfiles().
|
|
||||||
On the other hand, dumb_register_stdfiles() will probably be faster. If
|
|
||||||
you are only ever going to load datafiles and never stand-alone files, you
|
|
||||||
can actually leave this step out; but I would recommend you put this in,
|
|
||||||
test your code with a stand-alone file, then follow the instructions in
|
|
||||||
the next section in order to adapt your code to use the datafile (you will
|
|
||||||
be reminded that you can remove the function call).
|
|
||||||
|
|
||||||
|
|
||||||
5. If you are using Allegro, you'll have to initialise Allegro's sound
|
|
||||||
system. In most cases the following line will do the job:
|
|
||||||
|
|
||||||
install_sound(DIGI_AUTODETECT, MIDI_NONE, NULL);
|
|
||||||
|
|
||||||
You may like to initialise a MIDI driver though; see Allegro's docs for
|
|
||||||
details. Put this line after allegro_init().
|
|
||||||
|
|
||||||
|
|
||||||
6. All pieces of music are stored in memory in DUH structs. To handle these,
|
|
||||||
you must define pointers to them. Such pointers look like this:
|
|
||||||
|
|
||||||
DUH *myduh;
|
|
||||||
|
|
||||||
You can of course replace 'myduh' with anything you like. If you are
|
|
||||||
unfamiliar with pointers, please see ptr.txt. It is very important that
|
|
||||||
you understand these if you wish to use DUMB correctly.
|
|
||||||
|
|
||||||
You do not have direct access to the contents of a DUH struct, so do not
|
|
||||||
try. DUMB's functions provide everything you need; if you disagree, please
|
|
||||||
let me know and I shall see what I can do. Contact details are at the end
|
|
||||||
of this file.
|
|
||||||
|
|
||||||
Given the above definition, you can load a piece of music using one of the
|
|
||||||
following lines, depending on what file format you want to load:
|
|
||||||
|
|
||||||
myduh = dumb_load_it("a_one.it");
|
|
||||||
myduh = dumb_load_xm("a_two.xm");
|
|
||||||
myduh = dumb_load_s3m("a_one_two.s3m");
|
|
||||||
myduh = dumb_load_mod("three_four.mod");
|
|
||||||
|
|
||||||
Obviously you can use relative or absolute paths as normal. You should
|
|
||||||
always use forward slash (/), not backslash (\), when coding in C and
|
|
||||||
similar languages.
|
|
||||||
|
|
||||||
Every piece of music you load must be unloaded when you've finished with
|
|
||||||
it. When you type the above line in, it is good practice to type the
|
|
||||||
following line in at the same time, but put it at the end of the program:
|
|
||||||
|
|
||||||
unload_duh(myduh);
|
|
||||||
|
|
||||||
You will now be able to use the DUH struct anywhere in between the two
|
|
||||||
lines you just added. There is no need to check the return value; if the
|
|
||||||
DUH failed to load for one reason or another (this could be due to lack of
|
|
||||||
memory as well as the file not being there), then DUMB will do nothing -
|
|
||||||
safely.
|
|
||||||
|
|
||||||
|
|
||||||
7. From this step onwards, it will be assumed you're using Allegro. If not,
|
|
||||||
please read these steps anyway, and then see the section entitled
|
|
||||||
"Rendering music into a buffer". You will have to write your own playback
|
|
||||||
code using whatever sound output system is available. Alternatively you
|
|
||||||
may like to write data to a file (especially if you have a file that
|
|
||||||
consumes a lot of processor time), but beware that any streaming audio
|
|
||||||
format is likely to be substantially larger than the module file you
|
|
||||||
generate it from, and formats like MP3 will be lower quality. You might
|
|
||||||
not be able to hear the difference between the MP3 and the original, but
|
|
||||||
many people can and don't like it, so please consider them. I'm one of
|
|
||||||
them. If you really want to use a lossy compression format, I highly
|
|
||||||
recommend Ogg Vorbis:
|
|
||||||
|
|
||||||
http://www.vorbis.com/
|
|
||||||
|
|
||||||
But I digress.
|
|
||||||
|
|
||||||
In order to play the DUH you loaded, you need to define a pointer to an
|
|
||||||
AL_DUH_PLAYER struct:
|
|
||||||
|
|
||||||
AL_DUH_PLAYER *dp;
|
|
||||||
|
|
||||||
Two of the functions you will need are prototyped as follows:
|
|
||||||
|
|
||||||
AL_DUH_PLAYER *al_start_duh(DUH *duh, int n_channels, long pos,
|
|
||||||
float volume, long bufsize, int freq);
|
|
||||||
|
|
||||||
void al_stop_duh(AL_DUH_PLAYER *dp);
|
|
||||||
|
|
||||||
As you can see, al_start_duh() returns a pointer to an AL_DUH_PLAYER
|
|
||||||
struct when you call it. You then pass this pointer to all the other
|
|
||||||
functions. Again, if it is a NULL pointer for whatever reason (usually
|
|
||||||
lack of memory), DUMB will safely do nothing. When you call al_stop_duh(),
|
|
||||||
the pointer becomes invalid and you should not use it again; if there's
|
|
||||||
any risk of the pointer being used again, it is wise to set it to NULL at
|
|
||||||
this point. You can reassign the variable with a new call to
|
|
||||||
al_start_duh() of course.
|
|
||||||
|
|
||||||
Set 'n_channels' to 1 or 2 for mono or stereo respectively. Note that this
|
|
||||||
parameter has nothing to do with the number of samples that can play at
|
|
||||||
once in a music module. Set 'pos' to 0 to play from the beginning; each
|
|
||||||
time you add 65536, you will have advanced one second into the piece. As a
|
|
||||||
general rule, set the volume to 1.0f and adjust it later if the music is
|
|
||||||
too loud or too quiet - but see Allegro's set_volume_per_voice() function
|
|
||||||
first.
|
|
||||||
|
|
||||||
'bufsize' can generally be set to 4096. If your music stutters, try
|
|
||||||
increasing it; if your game freezes periodically, try reducing it. Find a
|
|
||||||
happy medium. Set 'freq' to 48000 for the best quality, though 44100 will
|
|
||||||
do in most cases. 22050 will be fine for a lot of music, though 11025 may
|
|
||||||
sound muffled. You can choose any other value, higher, lower or in
|
|
||||||
between. If your music stutters, and increasing 'bufsize' doesn't fix it,
|
|
||||||
try reducing this value.
|
|
||||||
|
|
||||||
Once you have put in a call to al_start_duh(), it is good practice to
|
|
||||||
insert the call to al_stop_duh() at the same time. You must call
|
|
||||||
al_stop_duh() before the DUH is unloaded (unload_duh(), Step 6 above).
|
|
||||||
|
|
||||||
Don't get impetuous, your program is not ready yet! Proceed to Step 8.
|
|
||||||
|
|
||||||
|
|
||||||
8. DUMB does not play music in the background for you; if you were expecting
|
|
||||||
it to do so, please see the explanation at the end of this step. For your
|
|
||||||
music to be played, you have to call another function at regular
|
|
||||||
intervals. Here is its prototype:
|
|
||||||
|
|
||||||
int al_poll_duh(AL_DUH_PLAYER *dp);
|
|
||||||
|
|
||||||
Do NOT call this function from inside a timer function unless you really
|
|
||||||
know what you are doing. The reasons why this is bad are explained
|
|
||||||
further down. You should call it from your main program.
|
|
||||||
|
|
||||||
Simply writing the following line will be sufficient in general, if you
|
|
||||||
have a variable 'dp' that points to your AL_DUH_PLAYER struct.
|
|
||||||
|
|
||||||
al_poll_duh(dp);
|
|
||||||
|
|
||||||
As a general rule, calling this once for each logic update will do the
|
|
||||||
trick. If, however, you are executing time-consuming algorithms such as
|
|
||||||
software 3D rendering, you may wish to insert calls to this function in
|
|
||||||
the middle of those algorithms. You cannot call this function too often
|
|
||||||
(within reason); if it has nothing to do it will return immediately.
|
|
||||||
|
|
||||||
Exactly how often you need to call the function depends on the values for
|
|
||||||
'bufsize' and 'freq' that you passed to al_start_duh():
|
|
||||||
|
|
||||||
n = freq / bufsize;
|
|
||||||
|
|
||||||
You have to call al_poll_duh() at least n times a second. Do not hesitate
|
|
||||||
to call it more often for safety; if the sound stutters, you may need to
|
|
||||||
do just that. (Or you may need to increase the buffer size or reduce the
|
|
||||||
quality settings; the only way to find out is to try.)
|
|
||||||
|
|
||||||
For now, don't worry about al_poll_duh()'s return value. As soon as you
|
|
||||||
need it, it will be explained.
|
|
||||||
|
|
||||||
If you are happy, please skip to Step 9. If you were expecting DUMB to
|
|
||||||
play your music in the background, please read on.
|
|
||||||
|
|
||||||
The natural way to play music in the background on most operating systems
|
|
||||||
nowadays is to use threads. DOS was not built with multithreading in mind,
|
|
||||||
and its system operations (notably disk access) assume they will only be
|
|
||||||
used from a single thread.
|
|
||||||
|
|
||||||
Interrupts are the next best thing to threads. A DOS hardware interrupt
|
|
||||||
could be triggered at any moment, and a handler function will be called.
|
|
||||||
This is how Allegro's timer functions work. Unfortunately, what you can do
|
|
||||||
inside an interrupt handler is very limited. For one thing, all code and
|
|
||||||
data used by the handler must be locked in memory; if not, it could get
|
|
||||||
written to disk (virtual memory). If the main program was accessing the
|
|
||||||
disk when it got interrupted, the system would then die a horrible death.
|
|
||||||
This precludes the possibility of allocating extra memory inside the
|
|
||||||
handler, and DUMB does a lot of that in al_poll_duh().
|
|
||||||
|
|
||||||
Given DUMB's architecture, which cannot change for reasons which will
|
|
||||||
become apparent in future versions, this renders it impossible to come up
|
|
||||||
with a portable solution for making DUMB play music in the background.
|
|
||||||
Having said that, if you wish to write your own wrapper for al_poll_duh()
|
|
||||||
and use it in a thread, there is nothing stopping you. If you do do this,
|
|
||||||
you will have to be very careful when stopping the music; see the
|
|
||||||
description of al_poll_duh() in dumb.txt for more information.
|
|
||||||
|
|
||||||
So why not kill DOS? It is all too common a practice among programmers to
|
|
||||||
quote the phrase, "DOS is as dead as the dodo." Despite being a decidedly
|
|
||||||
derisible demonstation of the dreary device of alliteration, it shows a
|
|
||||||
distinct lack of experience. Many embedded systems still use DOS because
|
|
||||||
it provides hardware access capabilities and real-time possibilities
|
|
||||||
unparalleled by any current multitasking operating system. For an argument
|
|
||||||
closer to home, I used to use RHIDE for DOS before I switched to Linux,
|
|
||||||
and I have not found a single Freeware Windows IDE that measures up to
|
|
||||||
RHIDE. I'm sure many people are in the same boat, and really appreciate
|
|
||||||
DUMB's DOS port.
|
|
||||||
|
|
||||||
We will not be removing DOS support from DUMB. Any blind suggestions to do
|
|
||||||
so will be met with fiery flames. You have been warned.
|
|
||||||
|
|
||||||
|
|
||||||
9. Test your program!

Here I describe some common operations you may wish to perform. The method
|
|
||||||
for doing so will seem a bit strange sometimes, as will the names of the
|
|

structs. However, there is a reason behind everything. If you would like to

then see dumb.txt, which covers everything from the ground up.
|
|

|
|

|
|
||||||
To control playback quality:
|
|
||||||
|
|
||||||
#define DUMB_RQ_ALIASING
|
|

#define DUMB_RQ_LINEAR
|
|

extern int dumb_it_max_to_mix;
|
|

|
|
||||||
dumb_resampling_quality can be set to any of the DUMB_RQ_* constants
|
|
||||||
(except DUMB_RQ_N_LEVELS; see below). Resampling is the term given to the
|
|
||||||
process of adjusting a sample's pitch (in this context).
|
|
||||||
dumb_resampling_quality defaults to DUMB_RQ_CUBIC, which sounds nice but
|
|
||||||
takes a lot of processor power. Try reducing it if you have an older
|
|
||||||
computer or if you are trying to mix an insane number of samples (or
|
|
||||||
both!). See dumb.txt for details on what the different values actually do.
|
|
||||||
|
|
||||||
If you wish to give this option to your user, you can use
|
|
||||||
DUMB_RQ_N_LEVELS. All the values from 0 to DUMB_RQ_N_LEVELS - 1 will be
|
|
||||||
valid resampling levels. If a value outside this range is chosen, it is
|
|
||||||
not the end of the world; DUMB will behave as if you had chosen the value
|
|
||||||
at whichever extreme you went beyond.
|
|
||||||
|
|
||||||
dumb_it_max_to_mix, defaulting to 64, is the maximum number of samples
|
|
||||||
DUMB will ever mix together when playing an IT, XM, S3M or MOD file.
|
|
||||||
Unlike many other music systems, DUMB will still keep track of all samples
|
|
||||||
(up to a fixed maximum of 256 of them, roughly speaking), and then will
|
|
||||||
just render as many of them as this variable permits, starting with the
|
|
||||||
loudest ones. When samples are cut or come back in, the exact timings will
|
|
||||||
not generally be predictable - but nor will they be important.
|
|
||||||
|
|
||||||
dumb_it_max_to_mix applies to each currently playing module file
|
|
||||||
independently. So if you set it to 64, but render two modules
|
|
||||||
simultaneously, DUMB could end up mixing up to 128 samples.
|
|
||||||
|
|
||||||
|
|
||||||
To pause and resume playback, set the volume, get the current playback
|
|
||||||
position, or get the length of time a DUH will play for before either looping
|
|
||||||
or freezing (effect F00 in XM and MOD files, which means no new notes will be
|
|
||||||
played but any existing notes will continue):
|
|
||||||
|
|
||||||
void al_pause_duh(AL_DUH_PLAYER *dp);
|
|
||||||
void al_resume_duh(AL_DUH_PLAYER *dp);
|
|
||||||
void al_duh_set_volume(AL_DUH_PLAYER *dp, float volume);
|
|
||||||
long al_duh_get_position(AL_DUH_PLAYER *dp);
|
|
||||||
|
|
||||||
long duh_get_length(DUH *duh);
|
|
||||||
|
|
||||||
These functions are pretty self-explanatory. The volume passed to
|
|
||||||
al_duh_set_volume() and the position returned by al_duh_get_position() are
|
|
||||||
in the same units as those you passed to al_start_duh(). The length
|
|
||||||
returned by duh_get_length() is in the same units as the aforementioned
|
|
||||||
position; see dumb.txt for more information on this function. Be careful
|
|
||||||
with al_duh_get_position(); it will return a position slightly ahead of
|
|
||||||
what you can hear, because the system has to keep ahead slightly to avoid
|
|
||||||
stuttering.
|
|
||||||
|
|
||||||
|
|
||||||
To prevent the music from looping and/or freezing:
|
|
||||||
|
|
||||||
DUH_SIGRENDERER *al_duh_get_sigrenderer(AL_DUH_PLAYER *dp);
|
|
||||||
DUMB_IT_SIGRENDERER *duh_get_it_sigrenderer(DUH_SIGRENDERER *sigrenderer);
|
|
||||||
|
|
||||||
void dumb_it_set_loop_callback(DUMB_IT_SIGRENDERER *sigrenderer,
|
|
||||||
int (*callback)(void *data), void *data);
|
|
||||||
void dumb_it_set_xm_speed_zero_callback(DUMB_IT_SIGRENDERER *sigrenderer,
|
|
||||||
int (*callback)(void *data), void *data);
|
|
||||||
|
|
||||||
int dumb_it_callback_terminate(void *data);
|
|
||||||
|
|
||||||
If you are unfamiliar with function pointers, please see fnptr.txt.
|
|
||||||
|
|
||||||
Note that these functions apply to IT, XM, S3M and MOD files - not just to
|
|
||||||
IT files. This holds true throughout DUMB, for all functions with "it" in
|
|
||||||
the name. The xm_speed_zero event can only occur with XM and MOD files.
|
|
||||||
|
|
||||||
The first two functions will return a pointer to a struct contained by the
|
|
||||||
struct you pass. This system is necessary to ensure that these operations
|
|
||||||
are possible when not using Allegro. Typically you would write the
|
|
||||||
following code:
|
|
||||||
|
|
||||||
{
|
|
||||||
DUH_SIGRENDERER *sr = al_duh_get_sigrenderer(dp);
|
|
||||||
DUMB_IT_SIGRENDERER *itsr = duh_get_it_sigrenderer(sigrenderer);
|
|
||||||
dumb_it_set_loop_callback(itsr, &dumb_it_callback_terminate, NULL);
|
|
||||||
dumb_it_set_xm_speed_zero_callback
|
|
||||||
(itsr, &dumb_it_callback_terminate, NULL);
|
|
||||||
}
|
|
||||||
|
|
||||||
Once you have done this, the return value of al_poll_duh() becomes
|
|
||||||
significant. It will be 0 as long as the music is playing. When the music
|
|
||||||
stops, al_poll_duh() will return nonzero. You can call al_stop_duh() and
|
|
||||||
do something else as soon as you wish, but calling al_poll_duh() some more
|
|
||||||
will not do any harm.
|
|
||||||
|
|
||||||
al_poll_duh() will also return 1 if the music could not be loaded, or if
|
|
||||||
memory was short when trying to play it, or if it was a quirky music file
|
|
||||||
with no music in it (technically one with an empty order list). This
|
|
||||||
happens regardless of whether or not you execute the above code to disable
|
|
||||||
looping. Normally you shouldn't need to worry about this.
|
|
||||||
|
|
||||||
To undo the above and make DUMB loop or freeze again, pass NULL instead of
|
|
||||||
&dumb_it_callback_terminate. If you would like to fade on looping, or loop
|
|
||||||
a finite number of times, or display a message when looping, or whatever,
|
|
||||||
you will have to write your own callback function. In this case, please
|
|
||||||
see dumb.txt.
|
|
||||||
|
|
||||||
Note that the above code can safely be applied for a DUH that doesn't
|
|
||||||
contain a music module but contains some other kind of music.
|
|
||||||
duh_get_it_sigrenderer() will return NULL, and the code will do nothing.
|
|
||||||
|
|
||||||
|
|
||||||
To analyse the audio as it's generated:
|
|
||||||
|
|
||||||
typedef int sample_t;
|
|
||||||
|
|
||||||
typedef void (*DUH_SIGRENDERER_ANALYSER_CALLBACK)(void *data,
|
|
||||||
const sample_t *const *samples, int n_channels, long length);
|
|
||||||
|
|
||||||
void duh_sigrenderer_set_analyser_callback(DUH_SIGRENDERER *sigrenderer,
|
|
||||||
DUH_SIGRENDERER_ANALYSER_CALLBACK callback, void *data);
|
|
||||||
|
|
||||||
If the above confuses you, see fnptr.txt. These functions, along with
|
|
||||||
al_duh_get_sigrenderer() from the last section, enable you to register a
|
|
||||||
callback function. Every time some samples are generated, they will be
|
|
||||||
passed to this function. This enables you to display an oscilloscope or
|
|
||||||
spectrum analyser, for example.
|
|
||||||
|
|
||||||
Beware: your callback function may occasionally be called with
|
|
||||||
samples == NULL. This means the main program has decided to skip through
|
|
||||||
the music without generating any data. You should handle this case
|
|
||||||
elegantly, typically by returning immediately, but you may wish to make a
|
|
||||||
note of the fact that the music is being skipped, for whatever reason.
|
|
||||||
|
|
||||||
Beware again: if the main program ever calls duh_sigrenderer_get_samples()
|
|
||||||
on a buffer that isn't all silence, this callback function will be passed
|
|
||||||
the existing buffer after mixing, and thus it will include the original
|
|
||||||
data. This will not be an issue if you stick to duh_render(), which always
|
|
||||||
starts with a buffer filled with silence.
|
|
||||||
|
|
||||||
The samples array is two-dimensional. Refer to it as follows:
|
|
||||||
|
|
||||||
samples[channel_number][sample_position]
|
|
||||||
|
|
||||||
where 0 <= channel_number < n_channels,
|
|
||||||
and 0 <= sample_position < length.
|
|
||||||
|
|
||||||
In addition you can pass any 'data' pointer you like to
|
|
||||||
duh_sigrenderer_set_analyser_callback(), and this pointer will be relayed
|
|
||||||
to your callback function each time.
|
|
||||||
|
|
||||||
To remove the callback function, pass NULL to
|
|
||||||
duh_sigrenderer_set_analyser_callback().
|
|
||||||
|
|
||||||
|
|
||||||
Everything below this point assumes some knowledge of how a music module is
|
|
||||||
constructed. If you do not have this knowledge, talk to whoever is writing
|
|
||||||
music for you, or download a tracking program and play with it (see
|
|
||||||
readme.txt).
|
|
||||||
|
|
||||||
|
|
||||||
To start playing an IT, XM, S3M or MOD from an arbitrary order number (the
|
|
||||||
default being 0, the beginning of the song), use the following:
|
|
||||||
|
|
||||||
DUH_SIGRENDERER *dumb_it_start_at_order
|
|
||||||
(DUH *duh, int n_channels, int startorder);
|
|
||||||
AL_DUH_PLAYER *al_duh_encapsulate_sigrenderer
|
|
||||||
(DUH_SIGRENDERER *sigrenderer, float volume, long bufsize, int freq);
|
|
||||||
|
|
||||||
The usage of these functions is as follows:
|
|
||||||
|
|
||||||
{
|
|
||||||
DUH_SIGRENDERER *sr = dumb_it_start_at_order
|
|
||||||
(duh, n_channels, startorder);
|
|
||||||
dp = al_duh_encapsulate_sigrenderer(sr, volume, bufsize, freq);
|
|
||||||
}
|
|
||||||
|
|
||||||
Replace 'dp' with whatever your AL_DUH_PLAYER pointer is. You also need
|
|
||||||
to insert suitable values for n_channels, startorder, volume, bufsize and
|
|
||||||
freq. These have the same meaning as those passed to al_start_duh().
|
|
||||||
|
|
||||||
WARNING: after passing a pointer to an "encapsulate" function, do not use
|
|
||||||
that pointer again. (More specifically, do not use it again if
|
|
||||||
the function returns NULL, because the function will have
|
|
||||||
destroyed the pointer if this happens, to help prevent memory
|
|
||||||
leaks.) There will be a "get" function with which you can obtain
|
|
||||||
the original pointer if it is still valid, or NULL otherwise.
|
|
||||||
|
|
||||||
The above functions will fail (safely) if you try to use them with a DUH
|
|
||||||
that contains a different type of music.
|
|
||||||
|
|
||||||
Notice that there is no 'pos' parameter. If you would like to skip through
|
|
||||||
the music, you can use this function:
|
|
||||||
|
|
||||||
long duh_sigrenderer_get_samples(
|
|
||||||
DUH_SIGRENDERER *sigrenderer,
|
|
||||||
float volume, float delta,
|
|
||||||
long size, sample_t **samples
|
|
||||||
);
|
|
||||||
|
|
||||||
Pass 0 for volume and NULL for samples, and this function will skip
|
|
||||||
through the music nice and quickly. So insert the following between the
|
|
||||||
two above statements:
|
|
||||||
|
|
||||||
duh_sigrenderer_get_samples(sr, 0, 65536.0f / freq, pos, NULL);
|
|
||||||
|
|
||||||
Substitute for 'freq' and 'pos'. An explanation of the 'delta' parameter
|
|
||||||
can be found further down in this file.
|
|
||||||
|
|
||||||
Finally, note that duh_get_length() is only meaningful when you start
|
|
||||||
playing music from order 0.
|
|
||||||
|
|
||||||
|
|
||||||
If an IT file contains Zxx effects, DUMB will generate MIDI messages, which
|
|
||||||
will control the low-pass resonant filters unless the IT file actively
|
|
||||||
specifies something else. In rare cases this may not be what the Zxx effects
|
|
||||||
were intended to do; if this is the case, you can block the MIDI messages as
|
|
||||||
follows. Note that this does NOT mean filters are disabled; if an instrument
|
|
||||||
specifies initial cut-off and resonance values, or has a filter envelope,
|
|
||||||
then filters will be applied. It only makes sense to use this procedure at
|
|
||||||
the beginning of playback.
|
|
||||||
|
|
||||||
void dumb_it_set_midi_callback(DUMB_IT_SIGRENDERER *sigrenderer,
|
|
||||||
int (*callback)(void *data, int channel, unsigned char byte),
|
|
||||||
void *data);
|
|
||||||
|
|
||||||
int dumb_it_callback_midi_block(void *data, int channel,
|
|
||||||
unsigned char byte);
|
|
||||||
|
|
||||||
Using some functions described in the previous section, we arrive at the
|
|
||||||
following code:
|
|
||||||
|
|
||||||
{
|
|
||||||
DUH_SIGRENDERER *sr = al_duh_get_sigrenderer(dp);
|
|
||||||
DUMB_IT_SIGRENDERER *itsr = duh_get_it_sigrenderer(sigrenderer);
|
|
||||||
dumb_it_set_midi_callback(itsr, &dumb_it_callback_midi_block, NULL);
|
|
||||||
}
|
|
||||||
|
|
||||||
DUMB offers no way of disabling filters completely. Disabling filters is not
|
|
||||||
recommended as a means to reduce processor usage, as it will completely
|
|
||||||
damage any piece of music that uses the filters. If you want lower processor
|
|
||||||
consumption, use a piece of music that does not use filters.
|
|
||||||
|
|
||||||
|
|
||||||
Finally, DUMB offers a myriad of functions for querying and adjusting
|
|
||||||
module playback. Those beginning with "dumb_it_sd" operate on the
|
|
||||||
DUMB_IT_SIGDATA struct, which represents the piece of music before it starts
|
|
||||||
to play. Those beginning with "dumb_it_sr" operate on the DUMB_IT_SIGRENDERER
|
|
||||||
struct, which represents a currently playing instance of the music. Note that
|
|
||||||
duh_get_length(), described above, becomes meaningless after some of these
|
|
||||||
functions are used.
|
|
||||||
|
|
||||||
The method for getting a DUMB_IT_SIGRENDERER struct has already been given,
|
|
||||||
but the function prototypes are repeated here for convenience:
|
|
||||||
|
|
||||||
DUH_SIGRENDERER *al_duh_get_sigrenderer(AL_DUH_PLAYER *dp);
|
|
||||||
DUMB_IT_SIGRENDERER *duh_get_it_sigrenderer(DUH_SIGRENDERER *sigrenderer);
|
|
||||||
|
|
||||||
Getting a DUMB_IT_SIGDATA struct is simpler:
|
|
||||||
|
|
||||||
DUMB_IT_SIGDATA *duh_get_it_sigdata(DUH *duh);
|
|
||||||
|
|
||||||
For a list of dumb_it_sd_*() and dumb_it_sr_*() functions, please see
|
|
||||||
dumb.txt. These functions are new, and may not provide exactly what you need;
|
|
||||||
if not, please let me know.

**************************************************
|
|
||||||
*** Embedding music files in Allegro datafiles ***
|
|
||||||
**************************************************
|
|
||||||
|
|
||||||
|
|
||||||
In this section it is assumed you are already reasonably familiar with how
|
|
||||||
Allegro datafiles are used. If not, please refer to Allegro's documentation.
|
|
||||||
At the time of writing, the documentation you need is off the beaten track,
|
|
||||||
so to speak, in allegro/tools/grabber.txt.
|
|
||||||
|
|
||||||
To add a piece of music to a datafile, you need to create an object of type
|
|
||||||
"IT ", "XM ", "S3M " or "MOD " (note the spaces used as padding, although
|
|
||||||
you do not need to type these into the grabber). Then grab the piece of music
|
|
||||||
in. The grabber will treat it as a binary object. Save the datafile as usual.
|
|
||||||
|
|
||||||
|
|
||||||
To use a piece of music you added to the datafile, follow these steps:
|
|
||||||
|
|
||||||
|
|
||||||
1. Before loading the datafile, call one or more of these functions,
|
|
||||||
depending on which music format or formats you'd like to support:
|
|
||||||
|
|
||||||
dumb_register_dat_it(DUMB_DAT_IT);
|
|
||||||
dumb_register_dat_xm(DUMB_DAT_XM);
|
|
||||||
dumb_register_dat_s3m(DUMB_DAT_S3M);
|
|
||||||
dumb_register_dat_mod(DUMB_DAT_MOD);
|
|
||||||
|
|
||||||
Remember, do not call multiple functions unless you want to support
|
|
||||||
multiple formats. Calling more functions will add unused code to your
|
|
||||||
executable.
|
|
||||||
|
|
||||||
It is important that you make call these before loading the datafile,
|
|
||||||
since they tell Allegro how to load the respective files straight from
|
|
||||||
datafiles in the future. They will not help Allegro interpret any module
|
|
||||||
files that have already been loaded as binary objects (but if you really
|
|
||||||
need to interpret a module that has been loaded in this fashion, have a
|
|
||||||
look at dumbfile_open_memory() in dumb.txt).
|
|
||||||
|
|
||||||
If for whatever reason your music objects are identified by a different
|
|
||||||
type in the datafile, you can tell DUMB what that type is by changing the
|
|
||||||
parameter to the registration function above. Use Allegro's DAT_ID()
|
|
||||||
macro, e.g. DAT_ID('B','L','A','H'). This is not really recommended
|
|
||||||
though, since it would prevent a hypothetical grabber plug-in from being
|
|
||||||
able to play your music files. Use the above types if possible.
|
|
||||||
|
|
||||||
|
|
||||||
2. Whenever you need a pointer to a DUH struct, simply use the 'dat' field.
|
|
||||||
Do this in the same way you would for a pointer to a BITMAP struct or
|
|
||||||
anything else. If it makes you feel more comfortable, you can extract the
|
|
||||||
pointer in advance:
|
|
||||||
|
|
||||||
DATAFILE *dat = load_datafile("smurf.dat");
|
|
||||||
if (!dat) abort(); /* There are much nicer ways of handling failure! */
|
|
||||||
DUH *myduh = (DUH *)dat[GAME_MUSIC].dat;
|
|
||||||
|
|
||||||
Note that the explicit (DUH *) cast is only necessary for C++, not for C.
|
|
||||||
However, it does no harm.
|
|
||||||
|
|
||||||
Be sure that you do NOT call unload_duh() for anything stored in the
|
|
||||||
datafile. These DUHs will be freed when you call unload_datafile(), and
|
|
||||||
freeing them twice is practically guaranteed to crash your program.
|
|
||||||
|
|
||||||
|
|
||||||
3. If you only ever load music as part of a datafile, and you never load any
|
|
||||||
stand-alone music files, you do not need to register a file input system
|
|
||||||
for DUMB to use. If you followed the instructions for the first section
|
|
||||||
you will have one of these two lines in your program:
|
|
||||||
|
|
||||||
dumb_register_stdfiles();
|
|
||||||
dumb_register_packfiles();
|
|
||||||
|
|
||||||
You can safely delete this line - but only if you never load any
|
|
||||||
stand-alone music files. The debugging library will bale you out if you
|
|
||||||
delete it when you shouldn't; the optimised library won't.
|
|
||||||
|
|
||||||
|
|
||||||
*************************************
|
|
||||||
*** Rendering music into a buffer ***
|
|
||||||
*************************************
|
|
||||||
|
|
||||||
|
|
||||||
NOTE: much of the API formerly described in this section has been deprecated,
|
|
||||||
and you will need to alter your code. See deprec.txt for details. If
|
|
||||||
you are reading this section for the first time, you can ignore this
|
|
||||||
note.
|
|
||||||
|
|
||||||
Rendering to a buffer is similar to playing using an AL_DUH_PLAYER. However,
|
|
||||||
you must use a DUH_SIGRENDERER struct instead. Here are the functions:
|
|
||||||
|
|
||||||
DUH_SIGRENDERER *duh_start_sigrenderer
|
|
||||||
(DUH *duh, int sig, int n_channels, long pos);
|
|
||||||
|
|
||||||
int duh_sigrenderer_get_n_channels(DUH_SIGRENDERER *sigrenderer);
|
|
||||||
long duh_sigrenderer_get_position(DUH_SIGRENDERER *sigrenderer);
|
|
||||||
|
|
||||||
long duh_sigrenderer_get_samples(DUH_SIGRENDERER *sigrenderer,
|
|
||||||
float volume, float delta, long size, sample_t **samples);
|
|
||||||
|
|
||||||
long duh_render(DUH_SIGRENDERER *sigrenderer,
|
|
||||||
int bits, int unsign, float volume, float delta, long size, void *sptr);
|
|
||||||
|
|
||||||
void duh_end_sigrenderer(DUH_SIGRENDERER *sigrenderer);
|
|
||||||
|
|
||||||
The parameters to duh_start_sigrenderer() have the same meanings as those to
|
|
||||||
al_start_duh(). However, note that the volume is not set at this stage. You
|
|
||||||
pass the desired volume each time you want to render a block. The 'sig'
|
|
||||||
parameter should be set to 0 for now.
|
|
||||||
|
|
||||||
Notice that there are two rendering functions. duh_sigrenderer_get_samples()
|
|
||||||
will generate samples in the internal 32-bit format, with a normal range from
|
|
||||||
-0x800000 to 0x7FFFFF and with each channel in a separate array; duh_render()
|
|
||||||
will convert to 8 or 16 bits, signed or unsigned, with stereo samples
|
|
||||||
interleaved, left first.
|
|
||||||
|
|
||||||
When you call duh_render(), pass 8 or 16 for 'bits'. If you pass 8, 'sptr' is
|
|
||||||
expected to be an array of chars. If you pass 16, 'sptr' is expected to be an
|
|
||||||
array of shorts. Endianness therefore depends on the platform, and you should
|
|
||||||
not try to interpret 16-bit wave data as an array of chars (unless you're
|
|
||||||
writing highly system-specific code anyway). Because DUMB renders internally
|
|
||||||
with 32 bits, there is no significant speed increase in rendering an 8-bit
|
|
||||||
stream.
|
|
||||||
|
|
||||||
If you are rendering in stereo, make sure your 'sptr' array is twice as big!
|
|
||||||
|
|
||||||
If you set 'unsign' to a nonzero value, then the samples generated will be
|
|
||||||
centred on 0x80 or 0x8000, suitably stored in an array of unsigned chars or
|
|
||||||
unsigned shorts. If 'unsign' is zero, the samples will be centred on 0,
|
|
||||||
suitably stored in an array of signed chars or signed shorts. Note that 8-bit
|
|
||||||
WAV files are unsigned while 16-bit WAV files are signed. This convention was
|
|
||||||
used by the SoundBlaster 16 when receiving samples to be sent to the
|
|
||||||
speakers. If you wish to write 16-bit sample data to a WAV file, don't use
|
|
||||||
fwrite(); instead, take the shorts one at a time, split them up into chars as
|
|
||||||
follows, and write the chars to the file.
|
|
||||||
|
|
||||||
short sptr[n];
|
|
||||||
char lsb = (char)sptr[n];
|
|
||||||
char msb = (char)(sptr[n] >> 8);
|
|
||||||
|
|
||||||
For a 16-bit WAV file, write the LSB (less significant byte) first.
|
|
||||||
|
|
||||||
The following applies equally to duh_render() and
|
|
||||||
duh_sigrenderer_get_samples(), except where otherwise stated.
|
|
||||||
|
|
||||||
If you set 'delta' to 1.0f, the sound generated will be suitable for playback
|
|
||||||
at 65536 Hz. Increasing 'delta' causes the wave to speed up, given a constant
|
|
||||||
sampling rate for playback. Supposing you want to vary the playback sampling
|
|
||||||
rate but keep the pitch constant, here's the equation for 'delta':
|
|
||||||
|
|
||||||
delta = 65536.0f / sampling_rate;
|
|
||||||
|
|
||||||
'size' is the number of samples you want rendered. For duh_render(), they
|
|
||||||
will be rendered into an array which you pass as 'sptr'. Note that stereo
|
|
||||||
samples count as one; so if you set n_channels to 2, your array must contain
|
|
||||||
(2 * size) elements.
|
|
||||||
|
|
||||||
For duh_sigrenderer_get_samples() you will have to use the following
|
|
||||||
functions:
|
|
||||||
|
|
||||||
sample_t **create_sample_buffer(int n_channels, long length);
|
|
||||||
void destroy_sample_buffer(sample_t **samples);
|
|
||||||
|
|
||||||
void dumb_silence(sample_t *samples, long length);
|
|
||||||
|
|
||||||
create_sample_buffer() allocates the channels sequentially in memory, so the
|
|
||||||
following technique is valid:
|
|
||||||
|
|
||||||
sample_t **samples = create_sample_buffer(n_channels, length);
|
|
||||||
dumb_silence(samples[0], n_channels * length);
|
|
||||||
|
|
||||||
It is necessary to fill the buffer with silence like this because
|
|
||||||
duh_sigrenderer_get_samples() mixes what it renders with the existing
|
|
||||||
contents of the buffer.
|
|
||||||
|
|
||||||
The return values from duh_render() and duh_sigrenderer_get_samples() tell
|
|
||||||
you how many samples were actually generated. In most cases, this will be the
|
|
||||||
same as the 'size' parameter. However, if you reach the end of the DUH (which
|
|
||||||
will happen if you disable looping or freezing as described further up), this
|
|
||||||
function will return less. When that happens, you can assume the stream has
|
|
||||||
finished. In the case of duh_render(), the remainder of the array will not
|
|
||||||
have been initialised, so you either have to initialise it yourself or avoid
|
|
||||||
using it.
|
|
||||||
|
|
||||||
If for whatever reason duh_start_sigrenderer() returns NULL, then
|
|
||||||
duh_render() and duh_sigrenderer_get_samples() will generate exactly 0
|
|
||||||
samples, duh_sigrenderer_get_n_channels() will return 0,
|
|
||||||
duh_sigrenderer_get_position() will return -1, and duh_end_sigrenderer() will
|
|
||||||
safely do nothing.

*** Introduction ***
|
|
||||||
********************
|
|
||||||
|
|
||||||
ModPlug Tracker is a very popular tracker for Windows. Its popularity is due
|
|
||||||
to the intuitive interface and its many advanced features. The author has
|
|
||||||
done a good job with this piece of software, but sadly in doing so he has
|
|
||||||
desecrated the IT file format.
|
|
||||||
|
|
||||||
I am not against ModPlug Tracker being used to write music modules. As
|
|
||||||
already stated, it has some very advanced and convenient features; I use it
|
|
||||||
myself. However, I believe its users should be aware of the entire situation
|
|
||||||
before using it for any serious work.
|
|
||||||
|
|
||||||
ModPlug Tracker - http://www.modplug.com/
|
|
||||||
|
|
||||||
|
|
||||||
*************************
|
|
||||||
*** Incompatibilities ***
|
|
||||||
*************************
|
|
||||||
|
|
||||||
There are a few situations in which ModPlug Tracker misinterprets the
|
|
||||||
original module formats. I shall list the five I am most aware of, from least
|
|
||||||
to most annoying:
|
|
||||||
|
|
||||||
5. Create a multisample instrument, for example a piano. Play a low note.
|
|
||||||
Then go up the scale, but in the pattern data, make sure the instrument
|
|
||||||
column is blank; put in only the notes. Play this with ModPlug Tracker,
|
|
||||||
and play it with Impulse Tracker. Impulse Tracker changes sample as you go
|
|
||||||
up the scale; ModPlug Tracker does not.
|
|
||||||
|
|
||||||
4. Arpeggio and Retrigger Note effects behave badly when combined with
|
|
||||||
Portamento, which can appear in the volume column. While Retrigger Note
|
|
||||||
isn't too bad, Arpeggio sounds completely wrong. Try it and see what
|
|
||||||
happens. Then repeat the experiment in Impulse Tracker.
|
|
||||||
|
|
||||||
3. The filter algorithm is incorrect, in more ways than one. When Jeffrey Lim
|
|
||||||
programmed the low-pass resonant filters into Impulse Tracker, he used a
|
|
||||||
standard filter algorithm with a slight modification to achieve greater
|
|
||||||
resonance. ModPlug Tracker does not incorporate this modification.
|
|
||||||
Furthermore, ModPlug Tracker uses integer arithmetic with nowhere near
|
|
||||||
enough precision; the wave output is really poor in some cases. I don't
|
|
||||||
doubt it damages the acoustic properties of the filters in subtle ways.
|
|
||||||
|
|
||||||
2. When looping, ModPlug Tracker resets all variables. The original trackers
|
|
||||||
do not do this.
|
|
||||||
|
|
||||||
1. Worst of all, ModPlug Tracker has no regard for playback volume, and
|
|
||||||
generally has a much lower output level than the original trackers.
|
|
||||||
|
|
||||||
Cases 3, 2 and 1 lead people to write IT files that play badly in the
|
|
||||||
original trackers. If some of these problems could be fixed, I'd be all for
|
|
||||||
it - but these problems have been reported to the author and he had no
|
|
||||||
motivation to fix them. ModPlug Tracker has been around long enough that
|
|
||||||
fixing 3, 2 and 1 would be detrimental to too many people's music.
|
|
||||||
|
|
||||||
|
|
||||||
******************
|
|
||||||
*** Extensions ***
|
|
||||||
******************
|
|
||||||
|
|
||||||
Worse than the incompatibilities are the extensions ModPlug Tracker makes,
|
|
||||||
mostly to the IT format. DUMB currently supports one of these extensions,
|
|
||||||
namely stereo samples, but supporting the others is not high on my list of
|
|
||||||
priorities.
|
|
||||||
|
|
||||||
Other extensions ModPlug Tracker has provided mostly take the form of extra
|
|
||||||
effects. For instance, S98 and S99 can be used to enable or disable reverb. I
|
|
||||||
believe the latest versions of ModPlug Tracker offer alternative types of
|
|
||||||
filter, such as high-pass and band-pass. As soon as an IT file uses any of
|
|
||||||
these features, it will play incorrectly with Impulse Tracker.
|
|
||||||
|
|
||||||
By far the most evil extension provided by ModPlug Tracker is the effect
|
|
||||||
plug-ins. These enable IT files to use VST effects. I recently downloaded an
|
|
||||||
IT file that uses some effects from a collection named "DirectX Media Audio
|
|
||||||
Effects". When can we expect these effects to be ported to Linux?
|
|
||||||
|
|
||||||
|
|
||||||
******************
|
|
||||||
*** Conclusion ***
|
|
||||||
******************
|
|
||||||
|
|
||||||
ModPlug Tracker is trying to be two things at once. It wants to be an editor
|
|
||||||
for the existing formats, but at the same time it wants to be proprietary,
|
|
||||||
with all its own features and extensions. Unfortunately it is succeeding;
|
|
||||||
there are many IT files out there that only play right in ModPlug Tracker. In
|
|
||||||
my opinion, ModPlug Tracker should have come out with its own file format, in
|
|
||||||
which all these extensions would have found a home.
|
|
||||||
|
|
||||||
If you are going to use ModPlug Tracker's extensions, I recommend you
|
|
||||||
ultimately convert your music to a streamed format such as Ogg Vorbis. (If
|
|
||||||
you were thinking of using MP3, then don't - consider using Ogg Vorbis
|
|
||||||
instead.) If you release IT files that use ModPlug Tracker's extensions,
|
|
||||||
please state prominently that the files are designed to be played with
|
|
||||||
ModPlug Tracker. Finally, don't ask me to support ModPlug Tracker's
|
|
||||||
extensions; ModPlug Tracker's playback code is available for use in your
|
|
||||||
games, so use that instead.
|
|
||||||
|
|
||||||
Ogg Vorbis - http://www.vorbis.com/
|
|
||||||
|
|
||||||
Despite all the above problems, don't forget that ModPlug Tracker does have a
|
|
||||||
lot of very useful features for editing files. These include a function for
|
|
||||||
removing unused patterns, samples and instruments, drag-and-drop sample and
|
|
||||||
instrument ripping, drop-down menus for selecting the effects by name without
|
|
||||||
having to memorise the codes or refer to help, and lots of other nice things.
|
|
||||||
I do recommend it as an editor, provided you make sure you are aware of the
|
|
||||||
situation and do not use ModPlug Tracker's extensions or incompatibilities
|
|
||||||
inadvertently.
|
|
||||||
|
|
||||||
Oh, and by the way, save your final version with Impulse Tracker. Then the
|
|
||||||
samples will be compressed for you!

|
|
||||||
|
|
||||||
|
|
||||||
A pointer is a small variable (often the same size as an int BUT NOT ALWAYS)
|
|
||||||
that holds the address of something in memory. You create a pointer by adding
|
|
||||||
a * to a variable, as follows:
|
|
||||||
|
|
||||||
int x, *y;
|
|
||||||
|
|
||||||
x = 5;
|
|
||||||
y = &x;
|
|
||||||
|
|
||||||
The & means 'address of', so &x gives us a pointer to x. We are storing it in
|
|
||||||
y.
|
|
||||||
|
|
||||||
(*y)++;
|
|
||||||
|
|
||||||
The * here means 'value at'. It's known as the 'dereferencing' operator. When
|
|
||||||
written before a pointer, as it is here, it allows you to treat the value
|
|
||||||
like a normal variable. In this case we are incrementing the value. If we
|
|
||||||
look at x, we'll find that it now contains 6, not 5.
|
|
||||||
|
|
||||||
y++;
|
|
||||||
|
|
||||||
Here we are incrementing the pointer itself. This is useful for traversing
|
|
||||||
through an array, but in this particular example it is not much use.
|
|
||||||
|
|
||||||
*y++;
|
|
||||||
|
|
||||||
Beware; this will increment the pointer, not the value stored there. It will
|
|
||||||
return the value stored at the pointer (before incrementing the pointer), so
|
|
||||||
you can use this in a bigger expression. This is why we needed brackets in
|
|
||||||
the first example.
|
|
||||||
|
|
||||||
Note that you will not need these three examples when working with DUMB; they
|
|
||||||
are simply to help illustrate the idea of pointers.
|
|
||||||
|
|
||||||
Also be aware that when defining pointers you attach the * to the variable,
|
|
||||||
not to the type. The following example will create a pointer and an int, not
|
|
||||||
two pointers:
|
|
||||||
|
|
||||||
int *a, b;
|
|
||||||
|
|
||||||
That is why I believe it's a good idea to put a space before the * and not
|
|
||||||
after it, although programmers are divided on this.
|
|
||||||
|
|
||||||
y = 0;
|
|
||||||
y = NULL;
|
|
||||||
|
|
||||||
These two statements are equivalent. 0, or NULL, is a special value that is
|
|
||||||
guaranteed to have a different value from any valid pointer. This is most
|
|
||||||
often used to indicate that something doesn't point anywhere. DUMB's
|
|
||||||
functions may return it on occasion. However, in simple usage of DUMB, you
|
|
||||||
will not actually need to check for it.
|
|
||||||
|
|
||||||
Some of DUMB's functions return pointers to structs. (A struct is an
|
|
||||||
aggregration of other variables, such as ints, pointers, or other structs.
|
|
||||||
You can generally treat a struct as a single unit.) Here's an example of such
|
|
||||||
a function:
|
|
||||||
|
|
||||||
DUH *dumb_load_it(const char *filename);
|
|
||||||
|
|
||||||
You do not know what the DUH struct actually contains; dumb.h and aldumb.h
|
|
||||||
only give the compiler enough information to deal with pointers to them. DUMB
|
|
||||||
will take charge of everything that happens inside a DUH struct.
|
|
||||||
|
|
||||||
The above function will create a DUH struct for you. First it allocates
|
|
||||||
the memory it needs, then it fills the struct with data, then it returns a
|
|
||||||
pointer. This DUH struct will contain the data necessary to play an IT file.
|
|
||||||
You can define a suitable variable and store the pointer in it as follows:
|
|
||||||
|
|
||||||
DUH *duh = dumb_load_it("music.it");
|
|
||||||
|
|
||||||
Or this can be split up:
|
|
||||||
|
|
||||||
DUH *duh;
|
|
||||||
duh = dumb_load_it("music.it");
|
|
||||||
|
|
||||||
In order to use this DUH struct later, you must pass its pointer to other
|
|
||||||
functions. To pass the pointer to a function, simply write 'duh' for the
|
|
||||||
appropriate parameter.
|
|
||||||
|
|
||||||
When you've finished with a DUH struct (this applies equally to the other
|
|
||||||
structs DUMB deals with), you must pass it to an appropriate function for
|
|
||||||
freeing up the memory:
|
|
||||||
|
|
||||||
unload_duh(duh);
|
|
||||||
|
|
||||||
After you've done this, the memory will no longer be allocated, and the
|
|
||||||
pointer will have no meaning. You may wish to set it to NULL at this point
|
|
||||||
for safety. Alternatively just be sure not to use the present value of the
|
|
||||||
pointer any more. You can of course assign a new value to the pointer, e.g.
|
|
||||||
by calling dumb_load_it() again.
|
|
||||||
|
|
||||||
Note the following:
|
|
||||||
|
|
||||||
DUH *duh2 = duh;
|
|
||||||
|
|
||||||
This only duplicates the pointer, not the DUH itself. You still only have one
|
|
||||||
copy of the DUH. There is no way of duplicating a DUH, short of loading it
|
|
||||||
twice. This is not a problem, because DUMB can play it 'twice at the same
|
|
||||||
time' anyway.
|
|
||||||
|
|
||||||
That should be all you need to know about pointers in order to use DUMB. If
|
|
||||||
there's anything you feel should be explained better here, or anything else
|
|
||||||
that should be added, please don't hesitate to let me know!

*** Introduction ***
|
|
||||||
********************
|
|
||||||
|
|
||||||
|
|
||||||
Welcome to the DUMB Programmers' Tutorial!
|
|
||||||
|
|
||||||
In order to follow this tutorial, you should already have set Allegro and
|
|
||||||
DUMB up on your system, including DUMB's support for Allegro and the example
|
|
||||||
programs. If you have not done so, see readme.txt for details.
|
|
||||||
|
|
||||||
You will also need some IT files. If you would like to compose your own, then
|
|
||||||
first I must offer a word of warning: not everyone is capable of composing
|
|
||||||
music. Do not assume you will be able to learn the art. By all means have a
|
|
||||||
go; if you can learn to play tunes on the computer keyboard, you're well on
|
|
||||||
the way to being a composer!
|
|
||||||
|
|
||||||
The best program for the job is Impulse Tracker itself, available from:
|
|
||||||
|
|
||||||
http://www.noisemusic.org/it/
|
|
||||||
|
|
||||||
This is a DOS program. Users of DOS-incapable operating systems may like to
|
|
||||||
try ModPlug Tracker, but should be aware that it does not support all
|
|
||||||
combinations of effects correctly, and some IT files will sound wrong. If you
|
|
||||||
use a different operating system, or if you know of a better IT editor for
|
|
||||||
Windows, please give me some links so I can put them here!
|
|
||||||
|
|
||||||
ModPlug Tracker is available from: http://www.modplug.com/
|
|
||||||
|
|
||||||
If you would like to download IT files composed by other people, check the
|
|
||||||
following sites:
|
|
||||||
|
|
||||||
http://www.modplug.com/
|
|
||||||
http://www.traxinspace.com/
|
|
||||||
|
|
||||||
Once again, if you know of more sites where IT files are available for
|
|
||||||
download, please let me know.
|
|
||||||
|
|
||||||
Once you've got some IT files, we're ready to begin!
|
|
||||||
|
|
||||||
Note that support for S3M files has very recently been added to DUMB, but it
|
|
||||||
is bound to be faulty. I recommend you use IT files in preference until later
|
|
||||||
releases of DUMB.
|
|
||||||
|
|
||||||
|
|
||||||
******************
|
|
||||||
*** Try It Out ***
|
|
||||||
******************
|
|
||||||
|
|
||||||
|
|
||||||
We'll start simply by running one of the example programs.
|
|
||||||
|
|
||||||
Find playit.exe, in the dumb/examples folder. Choose an IT file, and pass it
|
|
||||||
to playit.exe. In DOS, you can do this by typing 'playit' followed by the
|
|
||||||
name of the IT file. In Windows, you can drag the IT file and drop it on
|
|
||||||
playit.exe.
|
|
||||||
|
|
||||||
You should now hear the music play back. If not, make sure your speakers are
|
|
||||||
on and volume is not turned down. Try one of Allegro's example programs. If
|
|
||||||
you are using DJGPP under Windows, consider using a Windows compiler instead.
|
|
||||||
If you cannot get it working, see readme.txt for details on seeking help with
|
|
||||||
DUMB.
|
|
||||||
|
|
||||||
When you are satisfied, press any key to stop the music and return to the
|
|
||||||
operating system.
|
|
||||||
|
|
||||||
|
|
||||||

*** How Does It Work? ***
|
|
||||||
*************************
|
|
||||||
|
|
||||||
|
|
||||||
Now load playit.c into your favourite editor. Here is an explanation of what
|
|
||||||
it does:

# Please edit this file to control the playback quality for 'dumbplay'. Note
|
|
||||||
# that this does not affect DUMB when you use it in your own programs; you
|
|
||||||
# need to borrow some code from the example program in order to get that to
|
|
||||||
# happen.
|
|
||||||
|
|
||||||
# dumb_resampling_quality can be 0 for aliasing, 1 for linear interpolation
|
|
||||||
# or 2 for cubic interpolation. See docs/dumb.txt for details on what these
|
|
||||||
# terms mean.
|
|
||||||
|
|
||||||
# dumb_it_max_to_mix is the maximum number of samples DUMB will render at a
|
|
||||||
# time. See docs/dumb.txt for a more detailed description.
|
|
||||||
|
|
||||||
# Increase buffer_size to combat stuttering.
|
|
||||||
|
|
||||||
# The music module will be rendered at the sampling frequency specified by
|
|
||||||
# sound_freq. This variable is also used by Allegro for initialising the
|
|
||||||
# sound hardware.
|
|
||||||
|
|
||||||
# buffer_size and sound_freq are passed directly to al_start_duh(). See this
|
|
||||||
# function's description in docs/dumb.txt for information about how to use
|
|
||||||
# these variables.
|
|
||||||
|
|
||||||
# You can ignore the quality variable. Allegro uses it when relaying the
|
|
||||||
# audio stream to the sound card. Only a masochist would set it lower than 2;
|
|
||||||
# if your computer is powerful enough to run DUMB, it is powerful enough to
|
|
||||||
# use this setting with Allegro.
|
|
||||||
|
|
||||||
# For best results, choose a value for sound_freq that your sound card can do
|
|
||||||
# exactly. See Allegro's docs, "Standard config variables", for details. If
|
|
||||||
# you do not choose an exact value, Allegro will round it to the nearest
|
|
||||||
# value it can do; then when DUMB plays the stream at a sampling frequency of
|
|
||||||
# sound_freq, Allegro will have to resample it. Allegro's 'quality = 2'
|
|
||||||
# setting is only comparable with DUMB's 'dumb_resampling_quality = 1'
|
|
||||||
# setting. Therefore, in order to appreciate DUMB's cubic resampler fully,
|
|
||||||
# you will need to make sure Allegro doesn't do any resampling, by choosing
|
|
||||||
# an exact value for sound_freq.

reasons. Firstly, if many projects request an acknowledgement, the list of

licences, notably the GPL. See http://www.gnu.org/philosophy/bsd.html .]
|
acknowledgements can become quite unmanageable. Secondly, DUMB was placing

a restriction on the code using it, preventing people from using the GNU

General Public Licence which disallows any such restrictions. See

misrepresented as being the original software.

3. This notice may not be removed from or altered in any source distribution.

urge you to acknowledge its use.]

||||||
3:05 PM, you are not allowed to modify the Program for ten minutes. [This

|
|

clause, the reasoning behind which is far from obvious.]

5. Users who wish to use DUMB for the specific purpose of playing music are

required to feed their dog on every full moon (if deemed appropriate).

clause was.]

6. No clause in this licence shall prevent this software from being depended
|
||||||
|
upon by a product licensed under the GNU General Public Licence. If such a
|
||||||
|
clause is deemed to exist, Debian, then it shall be respected in spirit as
|
||||||
|
far as possible and all other clauses shall continue to apply in full
|
||||||
|
force.
|
||||||
|
|
||||||
|
8. Take the number stated as introducing this clause. Multiply it by two,
|
||||||
|
then subtract four. Now insert a '+' between the two digits and evaluate
|
||||||
|
the resulting sum. Call the result 'x'. If you have not yet concluded that
|
||||||
|
every numbered clause in this licence whose ordinal number is strictly
|
||||||
|
greater than 'x' (with the exception of the present clause) is null and
|
||||||
|
void, Debian, then you are hereby informed that laughter is good for one's
|
||||||
|
health and you are warmly suggested to do it. By the way, Clauses 4, 5 and
|
||||||
|
6 are null and void. Incidentally, I like Kubuntu. The work you guys do is
|
||||||
|
awesome. (Lawyers, on the other hand ...)

of merchantability or fitness for a particular purpose.

Some files generated or copied by automake, autoconf and friends are
|
||||||
|
available in an extra download. These fall under separate licences but are

all free to distribute. Please check their licences as necessary.

Getting on to IRC can be a steep cliff, but it is not insurmountable, and

by simple name with no path, then that is ideal.

it's well worth it. Once you have set up the client software, you need to

connect to a server. Here is a list of EFnet servers I have had success with.

If you successfully port DUMB to a new platform, please let me know!

Type "/server" (without quotes), then a space, then the name of a server.

This program will only be built if you have Allegro. Pass it the filename

This program is much the same as dumbout, but it writes a .wav file with

If you would like to compose your own music modules, then this section should
|
||||||
|
help get you started.
|
||||||
|
|
||||||
|
The best programs for the job are the trackers that pioneered the file
|
||||||
|
formats:
|
||||||
|
|
||||||
|
Impulse Tracker - IT files - http://www.lim.com.au/ImpulseTracker/
|
||||||
|
Fast Tracker II - XM files - http://www.fasttracker2.com/
|
||||||
|
Scream Tracker 3 - S3M files - No official site known, please use Google
|
||||||
|
|
||||||
|
MOD files come from the Amiga; I do not know what PC tracker to recommend for
|
||||||
|
editing these. If you know of one, let me know! In the meantime, I would
|
||||||
|
recommend using a more advanced file format. However, don't convert your
|
||||||
|
existing MODs just for the sake of it.
|
||||||
|
|
||||||
|
Fast Tracker II is Shareware. It offers a very flashy interface and has a
|
||||||
|
game embedded, but the IT file format is more powerful and better defined. By
|
||||||
|
all means try them both and see which you prefer; it is largely a matter of
|
||||||
|
taste (and, in some cases, religion). Impulse Tracker and Scream Tracker 3
|
||||||
|
are Freeware, although you can donate to Impulse Tracker and receive a
|
||||||
|
slightly upgraded version. DUMB is likely to be at its best with IT files.
|
||||||
|
|
||||||
|
These editors are DOS programs. Users of DOS-incapable operating systems may
|
||||||
|
like to try ModPlug Tracker, but should read docs/modplug.txt before using it
|
||||||
|
for any serious work. If you use a different operating system, or if you know
|
||||||
|
of any module editors for Windows that are more faithful to the original
|
||||||
|
trackers' playback, please give me some links so I can put them here!
|
||||||
|
|
||||||
|
ModPlug Tracker - http://www.modplug.com/
|
||||||
|
|
||||||
|
If you have an x86 Linux system with VGA-compatible hardware (which covers
|
||||||
|
all PC graphics cards I've ever seen), you should be able to get Impulse
|
||||||
|
Tracker running with DOSEMU. You will have to give it access to the VGA ports
|
||||||
|
and run it in a true console, as it will not work with the X-based VGA
|
||||||
|
emulation. I personally added the SB16 emulation to DOSEMU, so you can even
|
||||||
|
use filters! However, it corrupts samples alarmingly often when saving on my
|
||||||
|
system - probably a DOSEMU issue. If you set this up, I am curious to know
|
||||||
|
whether it works for you.
|
||||||

BEWARE OF WINAMP! Although it's excellent for MP3s, it is notorious for being
|
||||||
|
one of the worst module players in existence; very many modules play wrongly
|
||||||
|
with it. There are plug-ins available to improve Winamp's module support, for
|
||||||
|
example WSP.
|
||||||
|
|
||||||
|
Winamp - http://www.winamp.com/
|
||||||
|
WSP - http://www.spytech.cz/index.php?sec=demo
|
||||||
|
|
||||||
|
(There is a Winamp plug-in that uses DUMB, but it is unreliable. If anyone
|
||||||
|
would like to work on it, please get in touch.)
|
||||||
|
|
||||||
|
While I am at it I should also point out that Winamp is notorious for
|
||||||
|
containing security flaws. Install it at your own risk, and if it is your
|
||||||
|
work computer, check with your boss first!
|
||||||
|
|
||||||
|
Samples and instruments are the building blocks of music modules. You can
|
||||||
|
download samples at
|
||||||
|
|
||||||
|
http://www.tump.net/
|
||||||
|
|
||||||
|
If you would like to download module files composed by other people, check
|
||||||
|
the following sites:
|
||||||
|
|
||||||
|
http://www.modarchive.com/
|
||||||
|
http://www.scene.org/
|
||||||
|
http://www.tump.net/
|
||||||
|
http://www.homemusic.cc/main.php
|
||||||
|
http://www.modplug.com/
|
||||||
|
|
||||||
|
Once again, if you know of more sites where samples or module files are
|
||||||
|
available for download, please let me know.
|
||||||
|
|
||||||
|
If you wish to use someone's music in your game, please respect the
|
||||||
|
composer's wishes. In general, you should ask the composer. Music that has
|
||||||
|
been placed in the Public Domain can be used by anyone for anything, but it
|
||||||
|
wouldn't do any harm to ask anyway if you know who the author is. In many
|
||||||
|
cases the author will be thrilled, so don't hesitate!
|
||||||
|
|
||||||
|
A note about converting modules from one format to another, or converting
|
||||||
|
from MIDI: don't do it, unless you are a musician and are prepared to go
|
||||||
|
through the file and make sure everything sounds the way it should! The
|
||||||
|
module formats are all slightly different, and MIDI is very different;
|
||||||
|
converting from one format to another will usually do some damage.
|
||||||
|
|
||||||
|
Instead, it is recommended that you allow DUMB to interpret the original file
|
||||||
|
as it sees fit. DUMB may make mistakes (it does a lot of conversion on
|
||||||
|
loading), but future versions of DUMB will be able to rectify these mistakes.
|
||||||
|
On the other hand, if you convert the file, the damage is permanent.

||||||

|

* When a signal is initiated, it claims a reference number. If any other
|
|
||||||
* currently playing signal has the same number, that signal becomes
|
|
||||||
* anonymous and inaccessible; that is, if multiple signals were initiated
|
|
||||||
* with the same reference, the reference belongs to the most recent.
|
|
||||||
*
|
|
||||||
* Signals can be stopped, or have their pitch, volume or parameters changed,
|
|
||||||
* using the reference number. A signal may stop prematurely if it runs out
|
|
||||||
* of data, in which case the reference number becomes void, and operations
|
|
||||||
* on it will be ignored. Such a situation will not flag any kind of warning,
|
|
||||||
* since it may be the result of inaccuracies when resampling.
|
|
||||||
*
|
|
||||||
* The sequence consists of a series of commands. All commands begin with a
|
|
||||||
* long int, which is the time to wait after the last command (or the
|
|
||||||
* beginning of the sequence) before executing this command. 65536 represents
|
|
||||||
* one second. A time of -1 (or in fact any negative time) terminates the
|
|
||||||
* sequence, but any currently playing signals will continue until they run
|
|
||||||
* out. Make sure no non-terminating signals are playing when the sequence
|
|
||||||
* ends!
|
|
||||||
*
|
|
||||||
* The time, if nonnegative, is followed by one byte indicating the type of
|
|
||||||
* command. This byte can have the following values:
|
|
||||||
*
|
|
||||||
* SEQUENCE_START_SIGNAL
|
|
||||||
* unsigned char ref; - Reference. Need more than 256? Use two sequences,
|
|
||||||
* and get your brain seen to.
|
|
||||||
* int sig; - The index of the signal to initiate.
|
|
||||||
* long pos; - The position at which to start. 65536 represents one second.
|
|
||||||
* unsigned short volume; - Volume. 65535 represents the maximum volume, so
|
|
||||||
* you will want to go lower than this if you are
|
|
||||||
* playing more than one signal at once.
|
|
||||||
* signed short pitch; - Pitch. 0 represents a frequency of 65536 Hz. Scale
|
|
||||||
* is logarithmic. Add 256 to increase pitch by one
|
|
||||||
* semitone in the even temperament, or add 12*256 to
|
|
||||||
* increase pitch by one octave in any temperament
|
|
||||||
* (i.e. double the frequency).
|
|
||||||
*
|

PROPOSED CHANGE OF TERMINOLOGY:
|
|
||||||
|
|
||||||
Current situation:
|
|
||||||
|
|
||||||
A DUH comprises a number of "signals". A signal is an entity capable of
|
|
||||||
producing a stream of audio. When a signal is called upon to generate
|
|
||||||
sound, it may in turn call upon any other signals in the DUH and use the
|
|
||||||
sound from those in generating its own.
|
|
||||||
|
|
||||||
There are a number of "sigtypes", including 'SAMP' (a sample) and 'SEQU'
|
|
||||||
(a sequence). Every signal in a DUH must be of one of these known types.
|
|
||||||
Every sigtype is characterised by a four-byte identifier and the
|
|
||||||
following function prototypes:
|
|
||||||
|
|
||||||
typedef void signal_t;
|
|
||||||
typedef void sampinfo_t;
|
|
||||||
|
|
||||||
signal_t *load_signal(DUH *duh, DUMBFILE *file);
|
|
||||||
sampinfo_t *start_samples(DUH *duh, signal_t *signal, int n_channels, long pos);
|
|
||||||
void set_parameter(sampinfo_t *sampinfo, unsigned char id, long value);
|
|
||||||
long render_samples(sampinfo_t *sampinfo, float volume, float delta, long size, sample_t **samples);
|
|
||||||
void end_samples(sampinfo_t *sampinfo);
|
|
||||||
void unload_signal(signal_t *signal);
|
|
||||||
|
|
||||||
When a signal in a DUH needs to be loaded, DUMB's core first checks the
|
|
||||||
identifier. If it is unknown, load_duh() fails. Each known sigtype will
|
|
||||||
have pointers to the above functions, so DUMB's core will then call the
|
|
||||||
load_signal() function. This loads the "signal", which could consist of
|
|
||||||
sample data, or sequence data (like the patterns in a music module).
|
|
||||||
(There's ambiguity here; we use the word "signal" for the whole entity
|
|
||||||
and also for the specific data that distinguish it from other signals of
|
|
||||||
the same sigtype.)
|
|
||||||
|
|
||||||
Once a signal is in memory, it can be used to generate sound. Its
|
|
||||||
start_samples() function is called for that, and a "sampinfo" block is
|
|
||||||
returned; this will contain the current position and any necessary state
|
|
||||||
information. render_samples() generates sound, and end_samples() destroys
|
|
||||||
the sampinfo block.
|
|
||||||
|
|
||||||
DUMB's support for existing file formats is implemented as follows. First
|
|
||||||
a signal_t is constructed manually by reading the file. Then the special
|
|
||||||
make_duh() function is called. This creates a DUH struct with just one
|
|
||||||
signal in it, the one we just created. We provide all the above
|
|
||||||
functions, except load_signal(), since that has been bypassed. DUMB's
|
|
||||||
core now has our start_samples() etc. function for generating the sound,
|
|
||||||
and it has our unload_signal() function for getting the file out of
|
|
||||||
memory when we're done.
|
|
||||||
|
|
||||||
It is possible with some sigtypes to adjust their sound using
|
|
||||||
"parameters". set_parameter() is called for this. An example would be
|
|
||||||
changing the cut-off frequency for a signal that acts as a filter. I plan
|
|
||||||
to add a second version of this function that takes a pointer. This would
|
|
||||||
be used when manipulating DUHs in code; an example is when installing a
|
|
||||||
callback function for a music module file. It couldn't be used by a file
|
|
||||||
on disk.
|
|
||||||
|
|
||||||
This terminology is far from intuitive. Here are some proposals:
|
|
||||||
|
|
||||||
- The things DUHs are made of can still be called "signals".
|
|
||||||
- The types of signal can still be called "sigtypes" ("signal types").
|
|
||||||
- The signal-specific data can be called the "sigdata" ("signal data").
|
|
||||||
- The sampinfo block can be renamed to a "sigrenderer" ("signal renderer").
|
|
||||||
- The parameters can be called "sigparams" ("signal parameters").
|
|
||||||
|
|
||||||
This way we have some consistency between different parts of the library;
|
|
||||||
the API for rendering a DUH as a whole uses the term "renderer". We also
|
|
||||||
have a full name and an abbreviation for each term.
|
|
||||||
|
|
||||||
Any advances on this?

|
|
||||||
|
|
||||||
Todo/Wishlist:
|
|
||||||
|
|
||||||
* MOD/XM loading - change the effect memory system; it isn't robust when it
|
|
||||||
comes to remembering stuff from one pattern to the next.
|
|
||||||
* --- IMPORTANT --- Put link to IT in docs: http://www.noisemusic.org/it/
|
|
||||||
* --- IMPORTANT --- Twist the sample decompression algorithm around, since
|
|
||||||
it was derived from a GPL'd algorithm. We don't want
|
|
||||||
to have to put it under GPL! :) ... or, find out that it
|
|
||||||
wasn't originally written under the GPL and then credit
|
|
||||||
the bloke who wrote it :)
|
|
||||||
* MMX resamplers and downsamplers
|
|
||||||
* Ability to load *.it, *.xm directly into DUH structs (IT done)
|
|
||||||
* Ability to embed IT compressed samples... no, it's copyrighted. Let's do
|
|
||||||
our own :)
|
|
||||||
* Ability to embed ITs themselves (? not sure how useful that is)
|
|
||||||
* Remove cit.c
|
|
||||||
* Check all return values. I think the Winamp plug-in needs looking at...
|
|
||||||
* resample.c - it seems x*y is safe if 0<=x<=65535 and -32768<=y<=32768 or
|
|
||||||
vice versa. Check this is true on all compilers. If so, make
|
|
||||||
use of it to gain more accuracy.
|
|
||||||
* DUMB_IDs should always be long or always be int...
|
|
||||||
* Decide whether the load_signal function really needs the DUH parameter...
|
|
||||||
* Allow for DUH modularity; different pieces share samples etc.
|
|
||||||
|
|
||||||
* Fix makefile so it can manage without alld - or put note in the FAQ that
|
|
||||||
ppl must build alld
|
|
||||||
* Arrange to detect file types by extension (probably not by content though)
|
|
||||||
* Change aldmbd to aldmd in makefiles to maintain 8.3 compatibility
|
|
||||||
* Put dumb_resampling_quality and dumb_it_max_to_mix in howto.txt
|
|
||||||
* More info in howto.txt, in particular that install_sound() is needed...
|
|
||||||
* Add a sanity check for restart_position?
|
|
||||||
* Note in docs to let entheh know if you release a game using DUMB
|
|
||||||
|
|
||||||
|
|
||||||
STUFF TO FIX FOR THE FIRST RELEASE
|
|
||||||
==================================
|
|
||||||
|
|
||||||
General
|
|
||||||
-------
|
|
||||||
* Naming is a bit confusing sometimes...
|
|
||||||
* What to do about ASSERT() and TRACE() - they were hacked in when
|
|
||||||
the lib was split from Allegro, and they need replacing.
|
|
||||||
* Add some constants to dumb.h (DUMB_VERSION_STR etc.)
|
|
||||||
|
|
||||||
entheh
|
|
||||||
------
|
|
||||||
* Update docs, write more docs (a lot to do here!)
|
|
||||||
* Go through, eliminate warnings, resolve some "/** WARNING" comments
|
|
||||||
(they used to be #warning but Bob complained :)
|
|
||||||
* Program it to calculate the length of IT and S3M files (currently
|
|
||||||
always set to 10 minutes IIRC)
|
|
||||||
|
|
||||||
Bob
|
|
||||||
---
|
|
||||||
* dumb_resample() now has a volume parameter, so there are some extra
|
|
||||||
floating-point multiply ops that could possibly be optimised.
|
|
||||||
|
|
||||||
tjaden
|
|
||||||
------
|
|
||||||
* Test on Linux when it's all ready plz :)
