About variStretch
Concept: The app is a so-called time-stretch machine. The user can change the speed (0.5-2.0) of audio source in real-time using keyboard or slider at will. Usage: There are three play modes: 1) Tape (to change the both speed & pitch) 2) Phase Vocoder (to change the speed alone) 3) Thru (no processing) "Buffer Size" slider determines how long the data will be stored. "Buffer Clear" button will reset the buffer to be zero. System Requirements: AUv3 host
