Frequently asked questions
- Does shifting the pitch change the length of the track?
- No. The timing and duration stay exactly the same, so a pitched-up vocal still lines up with its backing track. Only the key moves up or down by the number of semitones you choose.
- How much can I shift the pitch?
- Up to twelve semitones in either direction, which is a full octave up or down. One or two semitones is enough to nudge a song into an easier key to sing; larger shifts create more dramatic effects.
- What is a semitone?
- A semitone is the smallest step between two notes on a keyboard, the gap from one key to the very next. Twelve of them make an octave, the point where the note sounds the same but higher or lower.
- Which audio formats work, and is my file kept private?
- You can pitch-shift MP3, WAV, OGG and M4A files and save the result as MP3 or WAV. Everything runs locally in your browser, so your track is never uploaded to a server, and there is no sign-up or watermark.
