hello I need to code the "whammy" effect (like http://www.digitech.com/products/whammy.htm ) but I didn't find any references to it on comp.dsp or other sites I checked Is there another name for this effect? Pitch Space maybe? thanks

As far as I can see, it's just a pitch shifter with some unique ways of controlling the pitch shift interval. I would start by searching for pitch shift algorithms.

Pitch Space maybe?Yes, that is a real time pitch shifter. Give an input signal containing frequencies (f0, f1, .. fn), the output will be a signal containing frequencies (a * f0, a * f1, ,, a * fn) where a is > 0. Good luck. This is very difficult to do well.
