Hi all, I find my self suddenly in need of high quality Matlab code to pitch shift arbitrary sounds for use as experimental stimuli, while preserving the temporal dynamics. I could equivalently use time-stretch code and resample back to the original time scale to get a pitch shift. I am aware that there are several techniques for doing this - phase-vocoder, granular resynthesis, other signal models... Who has some matlab code for their favorite technique? Thanks, John
