Phase Vocoder w/Pitch Shifting (Audio Examples and Free Software Download)

I've improved my Phase Vocoder application by adding in a resampler. Using the resampler in conjunction with my Phase Vocoder's existing time stretch/compress abilities allows for pitch shifting. Here's a demonstration:


The original version of my Phase Vocoder is described in detail here
