Re: [LAU] Timestretch without sample damage.

Well, using Audacity, I found silence at the end of the sample, and using
Rubberband I found a small chunk of silence around 10ms in from the start
of my sample. That was a wav which was reduced in time from around 3
seconds to 2.666 using cl. Would you like me to make the samples
available?
