I have a function that I use to do just this and it works quite well. 
It fins the befginnings and endings of samples by comparing a windowed 
average to thresholds that you specify. I've used it to cut all the 
piano samples from the McGill CD and much of the U Iowa sample data 
base. THe only downside is that it desnt use the 'run' loop, ie clm 
calls are made in a lisp loop so its not the speediest thing. Ill post 
it if you want to use it.
