hi

i'm lookig for a fft based pitchshifter. since you can play a soundfile with arbitrary speed but constant pitch usig a phaselocked vocoder, would it also be possible to use the same principle in order to build a pitchshifter that keeps the formants the same?

btw: i vaguely remember that i found once a collection of quite a lot example patches, that are not included in pd's doc.i lost them with the last computer crash. can anybody point me to a direction where to find them?

thanks
