VexWarp currently uses
dsp.js for its FFT, but will work with any FFT library that supports typed arrays. The meat of the algorthm is in
src/stretch.js, and it can be used in both batch and real-time applications.
See VexWarp in action here: VexWarp.
This repository contains all the code used in the above demo, and in the VexWarp Chrome extension.
