I'm in. Although, I have to read up on how to do C bindings first as I
haven't done this before. I guess GtkAda is a good source for examples
:-)

There are three libraries:

libao: 

   Libao is a cross-platform library that allows programs to output PCM
   audio data to the native audio devices on a wide variety of platforms.
   It currently supports:

       * OSS (Open Sound System)
       * ESD (ESounD)
       * ALSA (Advanced Linux Sound Architecture)
       * Sun audio system (used in Solaris, OpenBSD, and NetBSD)
       * aRts (Analog Realtime Synthesizer) 

(hope this can do input as well)

libogg:

   Libogg contains necessary functionality to create, decode, and work with
   Ogg bitstreams.

libvorbis:

 * libvorbisenc

    Libvorbisenc is a convenient API for setting up an encoding
    environment using libvorbis. Libvorbisenc encapsulates the actions
    needed to set up the encoder properly.

 * Vorbisfile

    The Vorbisfile library provides a convenient high-level API for
    decoding and basic manipulation of all Vorbis I audio streams.
    Libvorbisfile is implemented as a layer on top of Xiph.org's
    reference libogg and libvorbis libraries.

    Vorbisfile can be used along with any ANSI compliant stdio
    implementation for file/stream access, or use custom stream i/o
    routines provided by the embedded environment. Both uses are
    described in detail in this documentation.
