It more than (just) demonstrates the uses of the "soundtouch" library. I've used it to as a complete program when it comes to manipulating the tempo and pitch of a file. I can't compare this program to others (because it's the only pitch, time stretch utility I've used). But it sounds pretty good to my ears. Rocco
