Online Pitch Shifter (Semitones + Cents)

ToolsToday Change Pitch tool is a free online pitch shifter that lets you raise or lower audio pitch without installing any software. Shift pitch by semitones to change the musical key, and use cents for fine tuning. This is useful for singers matching a vocal range, musicians practicing in a different key, and creators making remixes or sound effects.

Upload your audio file, choose the desired semitone and cent values, and download the pitch-shifted result. The tool works on Windows, macOS, Linux, Android and iOS, with no signup and no watermarks.

How to choose pitch shift values

+1 to +2 semitones — slightly higher pitch (often used for vocal comfort)
-1 to -2 semitones — slightly lower pitch (helps reduce strain)
+12 / -12 semitones — one octave up or down
±10–50 cents — small corrections for tuning mismatches

Semitones vs Cents

Semitone — a larger musical step (e.g., moving to a different key)

Cent — a very small adjustment (100 cents = 1 semitone)

Use semitones for key changes and cents for fine tuning

Small cent changes can fix slightly “out of tune” recordings
