Audio Pitch Changer

Audio pitch shifting is useful for changing key, testing vocal ranges, creating practice tracks, matching music to a singer, sound design, language practice, and quick creative experiments.

Set semitones for musical transposition and cents for fine tuning. Positive values raise the pitch; negative values lower it while keeping playback speed close to the original.

Semitones, cents, and octaves

Twelve semitones equal one octave, and 100 cents equal one semitone. Use whole semitones to transpose a song or voice into another key, then use cents for small tuning corrections. The combined range supports shifts up to two octaves in either direction.

Pitch-shifting quality

The output is newly encoded in the selected format and quality. Extreme shifts can introduce metallic tones, blurred transients, or less natural speech, so preview the processed file before downloading it. Longer or lossless source files require more browser memory and processing time.

Audio processing runs locally. Use Audio Speed Changer when you want to change duration and tempo instead of musical pitch.

Audio Pitch Changer FAQ

Does changing pitch also change playback speed?

The tool compensates for the pitch shift so the result stays close to the original duration and speed. Large shifts can still introduce audible artifacts, so preview the output before downloading.

What is the difference between semitones and cents?

Twelve semitones equal one octave, and 100 cents equal one semitone. Use semitones for musical transposition and cents for fine tuning.

Is pitch-shifted audio re-encoded?

Yes. Pitch shifting creates a newly encoded file. Smaller shifts usually sound more natural, and a higher-quality output setting can reduce additional encoding loss but cannot remove processing artifacts.
