Voice Studio — Autotune & Voice Changer
Record your voice, hear it snapped perfectly in tune, then stack harmonies, sing over a beat and share the clip — 17 one-tap voices, nothing uploaded.
Headphones only — on speakers it will screech. There’s about a tenth of a second of delay.
The music never goes through your mic — it’s mixed in when you export, so your voice stays clean and the balance stays adjustable.
Hit start, then slide slowly from the lowest note you can hold down there all the way up to your highest. You get twelve seconds. It’ll work out your range and suggest a Sa that puts most exercises comfortably in reach.
Sing the sargam, or sing the words you already know over the top — the notes are the same either way. Everything here is out of copyright, which is why it can be published in full. For a song that is still in copyright, use the screen and paste the words in yourself.
Green blocks are the notes to hit. The yellow line is you.
Green swaras above were in tune, red drifted more than a quarter-tone, grey weren’t picked up at all. The take is saved in your list — play it back and listen for the red ones.
Paste your words below and they’ll scroll here while you record.
🔒 Whatever you paste stays in this browser tab and is gone when you close it. Tap the prompter to advance a line by hand, or leave auto-scroll on and it follows the speed above while you record.
Harmonies follow the key and scale set on the Tune tab, so they stay in tune with the song rather than sitting a fixed number of semitones away.
Video export isn’t available in this browser. The audio downloads work fine — or try Chrome.
🔒 Nothing is uploaded. Everything happens on your own device, and Share hands the file straight to the app you pick.
