SDL_sound. An abstract soundfile decoder.
|
|
|
|
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.
|
|
|

|
|
|
|
SDL_sound _REQUIRES_ Simple Directmedia Layer (SDL) to function, and cannot
|
|
be built without it. You can get SDL from http://www.libsdl.org/. SDL_sound
|
|
has only been tried with the SDL 1.2 series, but may work on older versions.
|
|
Reports of success or failure are welcome.
|
|
|
|
Some optional external libraries that SDL_sound can use and where to find them:
|
|
SMPEG (used to decode MP3s): http://icculus.org/smpeg/
|
|
libvorbisfile (used to decode OGGs): http://www.xiph.org/ogg/vorbis/
|
|
libSpeex (used to decode SPXs): http://speex.org/
|
|
libFLAC (used to decode FLACs): http://flac.sourceforge.net/
|
|
libModPlug (used to decode MODs, etc): http://modplug-xmms.sourceforge.net/
|
|
libMikMod (used to decode MODs, etc, too): http://www.mikmod.org/
|
|
|
|
Experimental QuickTime support for the Mac is included, but has not been
|
|
integrated with the build system, and probably doesn't work with
|
|
QuickTime for Windows.
|
|
|
|
These external libraries are OPTIONAL. SDL_sound will build and function
|
|
without them, but various sound file formats are not supported unless these
|
|
libraries are available. Unless explicitly disabled during initial build
|
|
configuration, SDL_sound always supports these file formats internally:
|
|
|
|
- Microsoft .WAV files (uncompressed and MS-ADPCM encoded).
|
|
- Creative Labs .VOC files
|
|
- Shorten (.SHN) files
|
|
- Audio Interchange format (AIFF) files
|
|
- Sun Audio (.AU) files
|
|
- MIDI files
|
|
- MP3 files (internal decoder, different than the one SMPEG uses)
|
|
- Raw waveform data
