Changes:
10102003 - Changed some SDL_Error()s to __Sound_SetError() in new DLS code
to fix linking issues.
10052003 - Fixed memory corruption when freeing DLS instruments,
and bug when timidity is initialized multiple times (Thanks, Sam!).
09252003 - Sam Lantinga added support for DLS instruments to the MIDI decoder.
09132003 - Happy September. Added Speex (.spx) decoder.
08052003 - Fixed MIDI decoder on bigendian systems.
03102003 - Never actually created samplelist_mutex (Thanks, Glenn Maynard!).
01122003 - Fix to smpeg.c's rewinding code (Thanks, Eric).
12212002 - Fixed ogg.c to decode a full buffer at a time instead of one ogg
packet per call, and mikmod has a check during initialization to
prevent a clash with SDL_mixer (Thanks, Eric).
12092002 - Changed Sound_Init()'s call to SDL_Init() to SDL_InitSubSystem(),
to prevent unwanted use of the SDL parachute (thanks, Glenn).
From the DESCR:
SDL_sound is a library that handles the decoding of several popular
sound file formats, such as .WAV and .MP3. It is meant to make the
programmer's sound playback tasks simpler. The programmer gives
SDL_sound a filename, or feeds it data directly from one of many
sources, and then reads the decoded waveform data back at her
leisure. If resource constraints are a concern, SDL_sound can
process sound data in programmer-specified blocks. Alternately,
SDL_sound can decode a whole sound file and hand back a single
pointer to the whole waveform. SDL_sound can also handle sample
rate, audio format, and channel conversion on-the-fly and behind-the-
scenes, if the programmer desires.
