livemix
A tool for automated downmixing of live multitrack sound recordings
... 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.
