SpeedUpSongsMove the pitch of a recording up or down without intentionally changing how long it lasts. Use semitone steps to explore different keys, experiment with a vocal tone or create an alternative sound for your own recording. The processing stays in your browser.
Change pitch in three steps
- Select a local audio file.
- Choose the number of semitones to shift. For example, +3 raises the sound by three semitones, while -3 lowers it.
- Listen to the automatically prepared preview and download an MP3 or WAV file when supported.
What is a semitone?
A semitone is one step in the common 12-tone musical scale. Moving a recording up 12 semitones raises it by one octave; moving it down 12 semitones lowers it by one octave. Digital pitch shifting works on the sound, not on individual notes in a separate music score.
Pitch changing is different from speeding up
If you simply play a song faster, the notes usually rise and the recording gets shorter. A pitch changer aims to move the musical notes while keeping the recording’s duration approximately the same. Large shifts can make voices or instruments sound less natural: listen to the preview before exporting.
If you want the opposite effect—change playback speed while keeping pitch—use our Audio Speed Changer.
Frequently asked questions
Does changing pitch change the song’s duration?
This tool aims to preserve the original duration while changing pitch. Minor differences may occur because of audio processing and encoding.
Can I shift a voice down?
Yes. Choose a negative semitone value to lower the pitch. The tone may sound different from a natural recording, particularly with larger changes.
What is the difference between pitch and tempo?
Pitch describes note height. Tempo describes musical pace. This tool changes pitch without intentionally speeding up or slowing down the recording.
Do I need to install anything?
No installation or account is required. The browser must support the advanced audio processing used by the pitch changer.
Does the original file leave my device?
No. The editing process uses the copy of the file you select locally in your browser.
