SpectralWarper : Phase Vocoder buffer and playback with transposition


This module pre-analyses the input sound and keeps the phase vocoder frames in a buffer for the playback. User has control on playback position and transposition.


Position :

Normalized position (0 -> 1) inside the recorded PV buffer. Buffer length is the same as the sound duration.

Transposition :

Pitch of the playback sound.

Graph Only

Overall Amplitude :
