Frequently asked questions
How many semitones is one key?
Each semitone is one piano key. +2 moves C to D; +12 is a full octave up.
Does it change the speed?
No — the tempo stays the same while the pitch moves.
Why does it sound slightly phasey?
Pitch shifting stretches and resamples the sound; large shifts (beyond ±5) add artifacts, especially on complex music.
