  • The Phase Vocoder – Part I

    The phase vocoder is a tool used to perform time-stretching and pitch-shifting on recorded sounds. Its name derives from the early "vocoders" (contraction from "voice encoders"), which used a set of bandpass filters in parallel over many frequency bands, to crudely analyze and reconstruct speech. In this article, Richard Dudas and Cort Lippe explain the workings of a phase-vocoder as well as how to construct and modify one in Max/MSP.
