SDL2_sound is SDL_sound but with a SDL2 backend. This 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 SDL2_sound a file-name, 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, SDL2_sound can process sound data in programmer-specified
blocks. Alternately, SDL2_sound can decode a whole sound file and hand
back a single pointer to the whole waveform. SDL2_sound can also handle
sample rate, audio format, and channel conversion on-the-fly and
behind-the-scenes.
