- Upload an audio file (MP3, WAV, or any format your browser can play), up to 6 minutes long.
- Choose the speed: 1.0 is the original, 0.5 is half speed, 2.0 is double speed. Pitch stays the same in every case.
- Press “Process” — longer files can take several seconds; everything runs in your own browser.
- Play back the result or download it as a WAV file.
- Great for transcribing solos by ear, studying fast passages, or reviewing a recording in more detail.
