VERY IMPORTANT NOTE FOR ANYBODY BUILDING FROM THE TRUNK: This commit adds support for FMOD Ex while at the same time removing support for FMOD 3. Be sure to update your SDKs. GCC users, be sure to do a "make cleandep && make clean" before building, or you will likely get inexplicable errors. - Fixed: If you wanted to make cleandep with MinGW, you had to specifically specify Makefile.mingw as the makefile to use. - Added a normalizer to the OPL synth. It helped bring up the volume a little, but not nearly as much as I would have liked. - Removed MIDI Mapper references. It doesn't work with the stream API, and it doesn't really exist on NT kernels, either. - Reworked music volume: Except for MIDI, all music volume is controlled through GSnd and not at the individual song level. - Removed the mididevice global variable. - Removed snd_midivolume. Now that all music uses a linear volume scale, there's no need for two separate music volume controls. - Increased snd_samplerate default up to 48000. - Added snd_format, defaulting to "PCM-16". - Added snd_speakermode, defaulting to "Auto". - Replaced snd_fpu with snd_resampler, defaulting to "Linear". - Bumped the snd_channels default up from a pitiful 12 to 32. - Changed snd_3d default to true. The new cvar snd_hw3d determines if hardware 3D support is used and default to false. - Removed the libFLAC source, since FMOD Ex has native FLAC support. - Removed the altsound code, since it was terribly gimped in comparison to the FMOD code. It's original purpose was to have been as a springboard for writing a non-FMOD sound system for Unix-y systems, but that never happened. - Finished preliminary FMOD Ex support. SVN r789 (trunk)

- The garbage collector is now run one last time just before exiting the game. - Removed movie volume from the sound menu and renamed some of the other options to give the MIDI device name more room to display itself. - Moved the midi device selection into the main sound menu. - Added FMOD as MIDI device -1, to replace the MIDI mapper. This is still the default device. By default, it uses exactly the same DLS instruments as the Microsoft GS Wavetable Synth. If you have another set DLS level 1 patch set you want to use, set the snd_midipatchfile cvar to specify where it should load the instruments from. - Changed the ProduceMIDI function to store its output into a TArray<BYTE>. An overloaded version wraps around it to continue to supply file-writing support for external Timidity++ usage. - Added an FMOD credits banner to comply with their non-commercial license. - Reimplemented the snd_buffersize cvar for the FMOD Ex sound system. Rather than a time in ms, this is now the length in samples of the DSP buffer. Also added the snd_buffercount cvar to offer complete control over the call to FMOD::System::setDSPBufferSize(). Note that with any snd_samplerate below about 44kHz, you will need to set snd_buffersize to avoid long latencies. - Reimplemented the snd_output cvar for the FMOD Ex sound system. - Changed snd_samplerate default to 0. This now means to use the default sample rate. - Made snd_output, snd_output_format, snd_speakermode, snd_resampler, and snd_hrtf available through the menu. - Split the HRTF effect selection into its own cvar: snd_hrtf. - Removed 96000 Hz option from the menu. It's still available through the cvar, if desired. - Fixed: If Windows sound init failed, retry with DirectSound. (Apparently, WASAPI doesn't work with more than two speakers and PCM-Float output at the same time.) - Fixed: Area sounds only played from the front speakers once you got within the 2D panning area.
