Frequently asked questions
- Does pitch shifting change the speed?
- No. SnapOtter separates pitch from tempo, so changing the pitch does not affect playback speed or duration. The audio plays at the same length but at a higher or lower pitch. Processing runs locally on your server.
- How many semitones can I shift?
- You can shift pitch by any number of semitones in either direction. Moderate shifts of a few semitones produce the most natural results. Larger shifts may introduce noticeable artifacts. All processing happens on your self-hosted server.
- Can I use this for musical transposition?
- Yes, pitch shifting by semitones is equivalent to musical transposition. Shifting up 2 semitones raises a song by one whole step. This is perfect for adapting backing tracks to a different key. Processing stays on your own infrastructure.
