Raise or lower the pitch of a song, voice or the sound of a video by up to an octave without changing its speed — to sing along in a different key or tune an instrument. Works with MP3, WAV, M4A, MP4 and more. All in your browser.
How it works
- Choose an audio or video file or drag it onto the page.
- Move the slider: each step is a semitone, 12 is a whole octave up, −12 an octave down.
- Click Change pitch and download the file in the same format (MOV is saved as MP4).
Frequently asked questions
Will the song get faster or slower?
No. The pitch changes while the tempo and the length stay the same.
How many semitones should I pick?
One semitone is one key on a piano. To move a song from C to D, raise it by 2; to make it easier for a lower voice, try −2 to −4.
Is it free?
