OCaml Pluggable Audio Manipulation Framework

This is a fun OCaml toy for playing with audio output. The intent of it is to be a pluggable, monadic thing that allows for easy hookup of audio processing routines with MP3 files as input and direct output to the default audio device as output. That said, what it basically is consists of an external interface to libmpg123 and libao with some monadic glue to facilitate the sort of messing around that is clearly the intent.
