Currently I am working on a program that uses minim to analyze songs and control DMX lights in real time to music. What I wold like to do is be able to crest Instrumental and vocal tracks from the sound file for internal use in the program. Such as set one light to the analysis of the vocals and another to the analysis of the vocals.

I know I can do this inside of audacity but would really like to find  out how I can do this inside of processing, short of writing my own library, since that would be an effort I know I don't have time for right now.

Thanks!
Paul
