FAQ

Frequently Asked Questions

Does pitch shifting change the speed of the song?
No! Our pitch shifter uses granular overlap-add time-domain synthesis to change musical pitch up or down without affecting the playback speed or duration.
What is a semitone?
A semitone is the smallest musical interval in Western music (one piano key). 12 semitones equal one full octave.
Is my audio kept private?
Yes. All pitch modulation is processed entirely inside your web browser. No files are transmitted to any server.
Can I change keys for karaoke and singing practice?
Yes, pitch shifting is ideal for transposing backing tracks or songs up or down to match your natural vocal range.
