[LAU] Command Line Audio Processing...

Howdy Folks- I am looking for a decent way to do this... What I have: CDs of Sound Effects Collections These can have a varying number of sound effects per track seperated by short periods of silence Tab Delineated ASCII text files These list every sound effect on said CDs, by Track and if applicable location in the track, unfortunatly not by time though. These also give basic information about each sound effect What I would like to be able to do... Take each track, either ripping or already-ripped, and then break each multi-sound track into individual files named by information gotten from the text file, tagged by info, and split based on the number of sounds that file says are there as well as the sections of silence. What I am not sure of: Is there a utility that either can split up files based off silence(Googled and couldn't find one but I thought I remembered a discussion about that here some time back), or at the very least return the location in time of said sections of silence for me to process using Sox. Any ideas? The rest I can figure out I am sure, just that one has me stumped. Seablade
