Shift any track up or down in semitones — without changing its tempo. Perfect for changing key, matching vocal range, or transposing a backing track.
Open the Audio Studio
Go to the DefyAudio Studio and upload your file.
Open the Effects tab
Switch to the Effects tab in the settings rail.
Set the Pitch slider
Move Pitch up or down by semitones (±12). The tempo stays exactly the same.
Export
Choose a format and download your transposed track — processed locally.
Independent of tempo
Change key by up to ±12 semitones while the speed stays identical.
Separate Speed control
Need to change tempo too? Speed is a separate slider — mix and match freely.
Match your vocal range
Transpose a backing track to a key you can actually sing.
A pitch shifter transposes audio to a different key while keeping the tempo unchanged — so a song stays the same length and speed, just higher or lower. This is essential for matching a backing track to your vocal range, transposing an instrument part, or creating harmony ideas.
DefyAudio decouples pitch from speed: the Pitch slider shifts the key in semitones without touching tempo, while a separate Speed control changes tempo without touching pitch. Use either independently, or both together.
Upload your file to DefyAudio, open the Effects tab, and move the Pitch slider — it shifts the key in semitones while the tempo stays the same.
Up to 12 semitones (a full octave) up or down.
Yes — the Speed slider is separate, so you can change tempo, pitch, or both independently.
No — pitch shifting runs in your browser, so your file stays on your device.
