The mixer can currently load Microsoft WAVE files and Creative Labs VOC files as audio samples, and can load MIDI files via Timidity and the following music formats via MikMod: .MOD .S3M .IT .XM. It can load Ogg Vorbis streams as music if built with the Ogg Vorbis libraries, and finally it can load MP3 music using the SMPEG library.

  What works:
 
    * Support for "decoding" raw audio samples.
    * Support for decoding Microsoft WAVE audio files (uncompressed and MS-ADPCM encoded waveforms are supported, currently) (.WAV).
    * Support for decoding various MPEG audio files through SMPEG (.MP3, .MPG, .MPEG).
    * Support for decoding MPEG-1 Layer 3 audio files internally (makes use of LGPL'd code from mpg123.) (.MP3).
    * Support for decoding MIDI music files (.MIDI, .MID).
    * Support for decoding Ogg Vorbis audio files through libvorbis (.OGG).
    * Support for decoding Speex voice files through libspeex (.SPX).
    * Support for decoding FLAC audio files through libFLAC (.FLAC, .FLA).
    * Support for decoding Creative Labs Voice files (.VOC).
    * Support for decoding Audio Interchange File Format files (.AIFF).
    * Support for decoding Shorten-compressed audio data (.SHN).
    * Support for Sun's audio format (.AU).
    * Support for decoding through MikMod. (.MOD, .IT, .XM, .S3M, .MTM, .669, .STM, .ULT, .FAR, .MED, .AMF, .DSM, .IMF, .GDM, .STX, .OKT).
    * Support for decoding through ModPlug. (.669, .AMF, .AMS, .DBM, .DMF, .DSM, .FAR, .IT, .MDL, .MED, .MOD, .MT2, .MTM, .OKT, .PTM, .PSM, .S3M, .STM, .ULT, .UMX, .XM)
    * Experimental support for decoding through Apple Quicktime (MacOS only).
