[linux-audio-user] looking for audio compositor/sequencer

Hi, I apologize if this question is off-topic for the list, although I believe this is an appropriate forum. I'm looking for a command-line or script-oriented audio compositor. Specifically, I'd like to be able to do something like: audio-composite track1.wav 100 track2.wav 200 > composited.wav and audio-composite would generate a new wav file which would consist of the sounds in track1.wav playing from the 100 second mark, and the sounds in track2.wav playing from the 200 second mark. I'm looking for something driven via the command-line or in a script because I want to composite close to a hundred different clips with second-accurate insertion points, so I don't much fancy doing this with the plethora of gui sound editors that exist. I've gone through Freshmeat and the best I've found so far is soxmix's ability to mix multiple wav files into one: with some appropriate munging, I could make that do what I want, but I'm hoping to find a tool built for the job. Any help greatly appreciated! Denis denism(a)cyberus.ca
