ABOUT THIS TOOL

Free Online Audio Speed & Pitch Changer

Slow down tracks for transcription, speed up practice loops, or shift pitch without changing tempo — and vice versa. Processing runs locally via Web Audio API for private, instant adjustments.

How it works

  1. 01Upload an audio file or select one from Library after sign-in.
  2. 02Adjust speed and pitch sliders independently — preview changes in real time.
  3. 03Fine-tune for practice, harmonic mixing prep, or vocal transposition workflows.

Key features

  • Independent speed and pitch control
  • Real-time preview in the browser
  • Local processing — files are not sent for analysis
  • Useful for DJ tempo matching and musician practice

Common questions

Yes. Speed and pitch are controlled separately so you can slow a track for learning without lowering the key, or transpose without altering BPM.
