FAQ
Does changing pitch speed up or slow the track? No. The tool compensates the speed so the length stays the same.
Is the file uploaded to a server? No. Everything runs in your browser.
Does a big shift distort the sound? The larger the shift (near ±12), the less natural it sounds; small shifts sound smoother.
