Pitch Changer

Raise or Lower the Key of a Song.

Change the pitch of a song or recording by semitones without changing its speed. Singers use it to move a backing track into their range.

Move a song up or down by as much as an octave in semitone steps. The tempo stays exactly as it was, so a backing track still fits the choreography or the band.

Singers use it to bring a song into their range, instrumentalists to match a recording to their tuning. Switch off speed correction and you get the old tape effect, where higher also means faster.

How to use the Pitch Changer tool

  1. Add the song or recording.
  2. Move the slider: each step is one semitone, twelve make an octave.
  3. Choose the format and download the new version.
  • Transposing a karaoke track to a comfortable key
  • Matching a recording to an instrument tuned differently
  • Making a voice sound slightly deeper or lighter

Tips for the best result

  • Two or three semitones are barely noticeable; beyond five the voice starts to sound unnatural.
  • From C major, +2 gives D major and −3 gives A major.

Frequently asked questions

What is a semitone?

The smallest step in Western music: from one piano key to the very next, black keys included.

Does the quality suffer?

Small shifts sound clean. Large shifts add a slightly grainy or hollow character, most audible on voices.

Can I change the key of a video's sound?

Add the video file; its sound is shifted and saved as audio.

How do I find the key of my song first?

This tool does not detect the key. Play along on an instrument or use the tuner on a long note.
