How to use the Audio Pitch Changer

  1. Choose an audio file.
  2. Move the slider — each step is a semitone, 12 is an octave.
  3. Apply, preview and download.

What does this tool do?

Singers transpose backing tracks to suit their range; musicians retune recordings to match an instrument; content creators shift voices for effect. The duration stays the same, so it still lines up with video.

Audio is processed on your own device and never uploaded.

Why use it?

  • Semitone accurate.
  • Length unchanged.
  • ±1 octave.
