Shift the pitch of a song without changing its speed

TutuAudio raises or lowers audio by 1 to 12 semitones without changing the speed — useful for moving a backing track into your vocal range. It runs in your browser with no upload; free, no sign-up. Beyond 5 semitones, voices start to sound clearly unnatural.

FAQ

Will the song get faster or slower?
No. Only the pitch moves; tempo and length stay the same.
How far can I shift it?
Up to 12 semitones (one octave) up or down. On vocals, more than 5 semitones sounds clearly unnatural; instrumentals tolerate a bit more.
Is my audio uploaded to your server?
No. Pitch shifting runs in your browser; the file never leaves your device.
Is it free? Do I need an account?
Free, no account, no usage limits, and no watermark on the export.
