Sing Any Song Pitch Shifter

Shift the key (pitch) of your current tab's audio in real time, so you can sing karaoke in a comfortable key.

Sing Any Song Pitch Shifter changes the key of the audio playing in your browser tab — in real time — so you can sing karaoke in a range that actually fits your voice. Too high to reach the chorus? Drop it a few semitones. Too low to feel it? Raise it. No more straining, and no more skipping a song because it's in the "wrong" key. HOW IT WORKS • Play an audio track in your tab. • Click the Sing Any Song Pitch Shifter icon to turn it on. • Shift the key up or down by semitones, or jump to a comfortable preset for lower or higher voices. • The audio is re-pitched instantly as it plays — the tempo stays exactly the same, only the key changes. BUILT FOR KARAOKE Designed to pair with the Sing Any Song karaoke web app, and works with the audio in any tab. PRIVATE BY DESIGN • All audio is processed locally on your own device using the browser's Web Audio API. • Nothing is ever recorded, stored, or sent anywhere. • It activates only on the tab where you click it, and requests no more permissions than it needs — no access to your browsing history, cookies, or passwords. Grab the mic and sing any song, in any key.
