How to change the pitch of a song
Open an MP3, WAV, M4A, or any audio file, pick how many semitones to move it up or down, and save it. The song keeps its tempo and length, so it's a pitch changer and key changer in one: move a song into a singer's range, or tune a track to play along with. A video's sound changes under its picture. It all runs in your browser, so the file stays on your device.

What to expect
- Supported inputs
- MP3, WAV, M4A, AAC, FLAC, OGG, Opus, AIFF, and other audio files, and videos (MP4, MOV, MKV, WebM) with sound.
- What happens
- The sound is stretched and resampled so its pitch moves by the semitones you choose while its length stays the same, then saved in its own format (FLAC as WAV). A video keeps its picture as it is.
- Limits
- Up to 12 semitones, an octave, each way. Big changes make voices sound less natural, as they do in every pitch shifter.
