Sing and hit the notes
Turn on your mic: you see where you land, and at the end you get a summary and the tricky spots.
FAQ
Is it free?
Yes. Uploading songs, backing tracks, notes, scoring, key change and karaoke videos are free once you sign up.
Do I need to install anything?
No, OnPitch runs in the browser on desktop and mobile: Chrome, Edge, Safari. You'll need headphones and a microphone — the built-in one works too.
Which song formats are supported?
Audio in MP3, M4A, WAV, FLAC, OGG and AAC up to 50 MB, plus MP4, MOV, WebM and MKV video — the audio is extracted right in the browser, so the video size doesn't matter. Songs can be up to 10 minutes long.
How does OnPitch know whether I'm hitting the notes?
An AI model detects the pitch of the original vocals, your pitch is tracked from the microphone right in the browser, and the two are compared note by note to a fraction of a semitone.
Can I make a backing track and download it?
Yes. The backing track and the separated vocals play right on the site, each with its own volume, and both can be downloaded as MP3. You can also download your recordings, a mix of everything, and karaoke videos as MP4.
How do I get rid of the delay between my voice and the music?
Run the short calibration on the song page — OnPitch measures your device's latency and accounts for it when scoring.
Where do the lyrics come from?
We look up synced lyrics by artist and title. If there aren't any, paste the lyrics yourself — we'll time them to the vocals.
Can I sing in a different key?
Yes, you can shift a song up to 6 semitones up or down. The backing track, notes and scoring shift with it.
Will a song with extreme vocals or a choir work?
You'll get a backing track, but the notes are harder to detect in such songs, so the scoring there is more approximate.
Are my recordings sent anywhere?
No. Your microphone is analyzed and recorded only on your device, and karaoke videos are put together in the browser too.
