Change Pitch

Free Online Pitch Shifter

Our free pitch shifter lets you raise or lower the pitch of any song by up to a full octave in either direction, without changing how fast it plays. You adjust the pitch in semitones — the smallest step between two notes on a piano — so you can nudge a track up or down by tiny amounts or move it a whole octave. Crucially, the tempo stays exactly the same, so the timing and groove of the music are never touched; only the notes get higher or lower.

That makes it incredibly useful for singers and musicians. If a song sits too high or too low for your voice, you can transpose it into a comfortable, singable key in seconds, which is perfect for practice, covers and karaoke. Instrumentalists use it to match a backing track to a guitar with a capo, a differently tuned instrument, or a transposing instrument like a trumpet or saxophone, without having to learn the part in a new key.

It is also a creative playground. Producers and content creators shift pitch up for a bright, chipmunk-style effect or down for a deep, dramatic, slowed-down feel. You can correct a recording that came out slightly sharp or flat, experiment with how a melody sounds in a different register, or build unique sound effects. Because changing the pitch does not speed up or slow down the audio, everything stays perfectly in time as you experiment.

Everything runs right inside your browser, so your audio is never uploaded to a server. It is fast, private, and there is no sign-up or watermark. Just drop in a file, drag the slider to the number of semitones you want, and download your pitch-shifted MP3.
