Voice tuner
Sing a note and the needle shows whether you are on pitch. Below is your pitch line over the notes. Tuning an instrument? Pick it below.
Microphone needed
Sound is analysed right in your browser and never uploaded. The browser will ask for permission once.
- Wear headphones when singing over a track so the music doesn't leak into the microphone.
- Audio interface with two inputs (Scarlett, etc.): the voice is found on either input automatically, and you can pick the channel in Settings.
- Level: loud parts should reach the yellow zone of the meter, but not the red.
How to check whether you sing in tune
- Allow the microphone and sing a note on "ah". The needle shows the deviation in cents: 100 cents is a semitone, anything within ±15 is in tune.
- Below, your pitch line is drawn over the notes: you can see where you scoop up into a note, where you go flat at the end of a phrase and what your vibrato looks like.
- Choose the key of your song — the notes of the scale light up and the off-key ones stand out.
- "Record and analyse" saves your singing and shows a detailed report: intonation, stability, breathing and range.

There are tuners for guitar (standard, Drop D, Open G and more), bass up to 5 and 6 strings, ukulele, violin, viola, cello, mandolin, balalaika, domra, banjo, 7-string guitar and a chromatic tuner.
Frequently asked questions
How do I know if I sing on pitch?
Sing into the tuner: a green needle near the centre means the note is clean. If your pitch line stays below the notes you are singing flat, above — sharp.
What are cents?
One hundredth of a semitone. Experienced singers stay within ±10–15 cents; more than 30 cents off is audible even to untrained listeners.
Does a phone microphone work?
Yes. The tuner runs in the browser on computers and phones as long as it can use the microphone.
