Pitch Shift raises or lowers the pitch of a clip without changing its speed — up to an octave in either direction, in semitone steps. Use it to match a key, create a chipmunk or deep-voice effect, or nudge a sample into tune. It's all processed in your browser, so nothing is uploaded.
Drop your file in and play it to hear the original pitch.
Move the slider up or down in semitones — up to +12 or -12, a full octave each way.
Export to apply the pitch shift and save the file.

No — the tempo stays the same. Only the pitch moves, so the clip is the same length.
Twelve semitones make an octave. +12 shifts up a full octave, -12 down a full octave; ±1 is a subtle nudge.
Keeping it within ±12 semitones preserves audio quality; beyond an octave, pitch-shifting artefacts become obvious.
