摘要: A system for pitch-shifting an audio signal wherein resampling is done in the frequency domain. The includes a method by converting to domain representation and then identifying specific region representation. being located at first location. Next, shifted second location form adjusted Finally, transformed time representing input with pitch. This eliminates expensive stage allows computational costs become independent of pitch modification factor.
