Extreme time-stretching for audio files in the browser using Web Audio API
Time stretching and pitch shifting: WSOLA, phase vocoder, phase-locked vocoder, transient-aware, PaulStretch, PSOLA, SMS
A modern Python implementation of Paul Nasca's extreme time stretch algorithm with minimal dependencies.
Implements a phase randomized Real FFT time stretch algorithm, the NessStretch, which splits the original sound file into 1-10 discrete frequency bands, and uses a decreasing frame size to correspond to increasing frequency, thus doing a excellent job of resolving shorter, noisier high-frequency sounds and creating rich, lush low frequency pads.
