[chuck-users] Audio Scrubbing???

Hi, I don't think "audio scrubbing" is the correct technical term for what I want to do... Maybe someone can suggest a better term? Here's what I want to do: I want to be able to move through a sound file along the time (or sample) "axis" while maintaining the pitch of the original. Here's how I think I would do it: The rate at which I am "scrubbing" through the sound file (using a wacom tablet for example) would be mySampleRate. I would then pitch shift by a factor of: originalSampleRate/mySampleRate Of course the devil is in the details... If anyone has a link to math or code that could help me that would be great... Or better yet, maybe Chuck has some UGens that can make this easier... B
