Frequently asked questions
What is pitch shifting?
Pitch shifting changes the musical pitch of audio without changing its speed. Shifting up makes voices higher (like a chipmunk), shifting down makes them deeper. This is different from simply speeding up or slowing down audio.
Can I change pitch without changing speed?
Yes — that is exactly what this tool does. It uses time-stretch algorithms to maintain the original duration while shifting pitch. Speed and pitch are adjusted independently.
What is the pitch range?
You can shift pitch up or down by up to 12 semitones (one full octave) in either direction. For most voice effects, 3-5 semitones produces noticeable but natural-sounding results.
