Phase_Vocoder
This MATLAB exercise implements a phase vocoder with the capability of speed-up or slow-down of a speech or audio signal by a factor 'r', where 'r' varies from 0.25 (slow-down by factor of 4) to 'r'=40 (speed-up by factor of 4). The speed-up or slow-down works by interpolating the Short Time Fourier Transform (STFT) magnitude and calculating the phase advance for the signal. The file '5.16 Phase Vocoder.pdf' provides a User's Guide for this exercise.
