Pitch & tempo
Shift pitch and tempo independently, or nudge both together for a natural tape-style change.
Morpha is a browser-based audio studio: reshape pitch, tempo, tone and stereo, apply vocal effects, turn a melody into a wordless hum, and anonymize voice recordings - all processed locally on your device, nothing uploaded.
Free · No sign-up · No installation
Every effect runs locally on your device. Your files never leave the browser.
