Matlab Phaser Setup Guide Analog Devices Wiki This example shows how to implement a phase vocoder to time stretch and pitch scale an audio signal. Fortunately, the answer is "yes." the phase vocoder makes improved frequency estimates by using phase information that the stft ignores.
Github Minoue Xx Visualize Phase Modulation With Matlab Practice Describes and links to an implementation of the phase vocoder algorithm for time scale modification of audio in the matlab language. This phase change occurs over a time period of la sample periods, la being the analysis length. we want to alter this phase change in order to vary either the tempo or the pitch of the audio. This project is an implementation of the original phase vocoder by flanagan & golden (1966) in matlab. the phase vocoder is described as a technique in which signals are represented by their short time phase and amplitude spectra. A collection of phase vocoder based time scale modification implementations. easch channel is processed individually, with no regard for relationships between channels.

Dan ellis has posted some clean and simple matlab software1 implementing time scale modification using the phase vocoder. It contains matlab implementations of various classical time scale modification (tsm) algorithms like ola, wsola, and the phase vocoder. furthermore, the toolbox also provides the code for a recently proposed tsm algorithm based on a combination of the classical algorithms as well as harmonic percussive source separation (hpss). A discussion of basic phase vocoding technology is given here with a more detailed pdf version here. this page shows my implementation in matlab, which you may find useful for experimentation. 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).
