About Change Audio Pitch

Change Audio Pitch shifts a song or recording higher or lower without changing its speed. Pick a shift between −12 and +12 semitones — a full octave in either direction — and the track keeps its original tempo while every note moves to the new pitch.

A live preview plays the shifted audio right in your browser before you commit, so you can find the right key by ear. Note that the quick preview also nudges the speed slightly; the final file is rendered properly on the server and keeps the original speed exactly.

It is a free tool for transposing backing tracks to fit your vocal range, practicing an instrument in a different key, or creating deep or chipmunk-style voice effects. Upload MP3, WAV, M4A, or OGG; the result downloads as an MP3.

How to use Change Audio Pitch

  1. Upload an audio file — MP3, WAV, M4A, or OGG.
  2. Choose the pitch shift in semitones, from one octave down to one octave up.
  3. Toggle the live preview to hear the new pitch before applying it.
  4. Click Change pitch and download the MP3 at the new pitch with the original speed preserved.

The in-browser preview uses a quick playback-rate trick, which changes speed a little along with pitch. The file you download is rendered with a proper pitch-shifting filter and keeps the original speed exactly.

Transposing a backing track or karaoke instrumental into your vocal key, practicing songs in easier keys, matching two tracks for a mix, or creating lower and higher voice effects from a recording.

Yes, it is free to use with no signup. Upload a file, choose the shift, and download the result as often as you need.
