Pitch Shifter: Change the Key of Any Song

Yes. It is free, has no watermark and needs no account, because all the processing happens on your own device.

No. The file is decoded and processed inside your browser and is never sent to GrooveSheet or anyone else.

Small shifts of one to three semitones sound natural on most music. Large shifts change the tone of voices, which start to sound deeper or brighter, as with any pitch shifter.

MP3, WAV, M4A, OGG and FLAC files that your browser can play. You download the shifted song as a WAV file.

Yes. Upload the song to GrooveSheet for sheet music and MIDI of the drums, bass, guitar or piano, and for stems you can play along with. Every song starts with a free 30-second preview.

Singers move a song into a key that suits their voice. Guitarists match a recording tuned down a half step without retuning. Horn and sax players move a track into a key that reads easily for their instrument. The tempo stays exactly the same.

The page decodes your file in the browser and runs it through Signalsmith Stretch, an open source time and pitch engine. It changes the pitch while keeping the length, and keeps the character of voices and instruments far better than simply speeding a record up.

A semitone is one key on a piano, from C to C sharp. Twelve semitones make an octave. Cents divide a semitone into 100 steps, for fine tuning a recording that sits between notes. Shifting by 2 semitones turns a song in A minor into B minor.

No. The free tools need no account and no download. They run in your browser, and nothing you play or drop in is uploaded.

Yes, in any current mobile browser. MIDI keyboards and pad controllers need Chrome, Edge or Opera, on a computer or an Android phone.

GrooveSheet turns any song into sheet music, MIDI and separated stems with AI: drums, bass, guitar, piano and more. Every song starts with a free 30-second preview.
