Pitch Shifter FAQ

Everything you need to know about changing the pitch and key of your music.

How do I change the pitch of a song?

Upload your audio file, adjust the Pitch Shift slider up or down (measured in semitones), and click Export WAV to download your pitch-shifted track.

Can I change a song's key without changing speed?

Yes! Our pitch shifter adjusts pitch independently of speed. The Speed control defaults to 100%, so your song stays at the original tempo while the key changes freely.

How many semitones is a key change?

Each semitone equals one half step. 12 semitones make a full octave. To transpose from C to D, shift +2 semitones. From C to E, shift +4. Use the slider to dial in the exact interval you need.

Is this pitch shifter free?

Yes! Our pitch shifter is 100% free. All processing happens in your browser — your files are never uploaded to any server.

How to Change the Pitch of a Song

Pitch shifting is essential for musicians, producers, and karaoke singers who need to transpose music to a different key. Whether you're matching a song to your vocal range, creating harmonies, or experimenting with creative effects, our free online pitch shifter lets you raise or lower the pitch of any audio file in seconds — without changing the tempo.

Upload any MP3 or WAV file, dial in the exact semitone shift you need, and export a high-quality WAV. Use the built-in trimmer to cut your pitch-shifted clip to the perfect length.
