Pitch Shifter

Raise or lower the key of a track without changing its speed. Move the slider by semitones, preview the new pitch, then export as MP3 or WAV. The timing stays exactly the same, so it stays in step with everything else.

Frequently asked questions

Does shifting the pitch change the length of the track?
No. The timing and duration stay exactly the same, so a pitched-up vocal still lines up with its backing track. Only the key moves up or down by the number of semitones you choose.
How much can I shift the pitch?
Up to twelve semitones in either direction, which is a full octave up or down. One or two semitones is enough to nudge a song into an easier key to sing; larger shifts create more dramatic effects.
What is a semitone?
A semitone is the smallest step between two notes on a keyboard, the gap from one key to the very next. Twelve of them make an octave, the point where the note sounds the same but higher or lower.
Is it really free, and is there a watermark?
It is free and there is no watermark, no sign-up and no email wall. You get the full-quality file straight back, with nothing added and nothing held behind a paywall.
Is my file uploaded to a server?
No. Everything runs locally in your browser. Your file is read and processed on your own device, nothing is uploaded, and nothing is logged or stored.
