How does this tool work?
Shift audio pitch without speeding up or slowing down the final duration.
The audio file is decoded directly in your browser, then the engine applies the selected shift from -12 to +12 semitones. It changes pitch while compensating for the related speed variation so the resulting duration stays close to the original. You can preview the processed audio before exporting it as WAV, with no file upload to a server.
How to use this tool
Import audio
Choose a supported audio file.
Set the shift
Choose between -12 and +12 semitones.
Preview and download
Listen to the result and export it as WAV.
Use cases
Transpose a music track
Shift a musical track by several semitones to test another key without changing its overall playback tempo.
Create a sound effect

Tips and best practices
- +12 semitones equals one octave.
- -12 semitones equals one octave down.
- The first processing run may load the local audio engine.
