Raise or lower the key of any song by up to 4 semitones. High-quality, formant-preserving pitch shifting — no chipmunk or giant-voice effect.
Pitch shifting changes how high or low a song sounds — measured in semitones (the smallest step in Western music, e.g. C to C♯). Unlike simply speeding up or slowing down playback, proper pitch shifting keeps the tempo exactly the same while only changing the key.
Our pitch shifter uses formant-preserving processing, so voices and instruments keep their natural character instead of sounding thin or robotic — no "chipmunk" effect going up, no "demon voice" effect going down.
