This function registers all the known audio file type handlers for al_load_sample(3alleg5), al_save_sample(3alleg5), al_load_audio_stream(3alleg5), etc.
Depending on what libraries are available, the full set of recognised extensions is: .wav, .flac, .ogg, .it, .mod, .s3m, .xm, .voc.
- Saving is only supported for wav files.
- The wav file loader currently only supports 8/16 bit little endian PCM files. 16 bits are used when saving wav files. Use flac files if more precision is required.
- Module files (.it, .mod, .s3m, .xm) are often composed with streaming in mind, and sometimes cannot be easily rendered into a finite length sample. Therefore they cannot be loaded with al_load_sample(3alleg5)/al_load_sample_f(3alleg5) and must be streamed with al_load_audio_stream(3alleg5) or al_load_audio_stream_f(3alleg5).
- .voc file streaming is unimplemented.
Return true on success.
