How it works
Transpose any audio file up or down by up to 12 semitones — a full octave. Good for matching a sample to your project key, practicing in a different key, or quick experiments. The result downloads as WAV. Note: for large shifts, tempo changes slightly in proportion to pitch — for small shifts (1–3 semitones) the difference is barely noticeable.
