livemix

Livemix will search directory tree for audio files, assuming each of them is a
separate track, then group them into sessions based on file size, and then
create a downmix for each session.
Silent tracks are ignored, the others are processed by applying some effects
such as compand, then normalized and then combined into downmix with equal
volume. Sessions are named by the time of recording in YYYYMMDD-HHMMSS format.

Intended use is to quickly generate mp3 previews of live multitrack music
recordings (such as rehearsals or live performances), created by some sound
recording software (Avid ProTools or Audacity for example).

Livemix uses SoX sound processing utity to do all the work with tracks
preprocessing and mixing, and LAME mp3 encoder to produce final mp3 file.
Therefore, livemix needs sox and lame executables to be in search path
or in the same dir as livemix executable.
