How does the tuner work?
It records short sound windows from your microphone and finds the repeating period of the waveform (autocorrelation), then converts that frequency to the nearest note and the offset in cents.
From the tool guide Ask a follow-upWhat are cents?
There are 100 cents in a semitone. Within about ±5 cents most people cannot hear that a note is out of tune.
From the tool guide Ask a follow-upWhat is A4 = 440 Hz?
The standard concert pitch. Some ensembles use 442 or 432 Hz, and baroque music often uses 415 Hz.
From the tool guide Ask a follow-upWhy does it not detect my note?
Play louder or closer to the microphone, reduce background noise, and play one note at a time.
From the tool guide Ask a follow-upDoes it work for bass and low notes?
Yes, down to about 30 Hz (low B on a five-string bass).
From the tool guide Ask a follow-upIs my audio recorded?
No. It is analysed live in your browser and discarded.
From the tool guide Ask a follow-upWhat this tool does
This online tuner listens to your instrument through your microphone and shows the note you are playing, its frequency in hertz and — most importantly — how many cents sharp or flat it is. A needle swings to the centre and turns green when the string is within five cents of perfect pitch, so you can tune by eye without any special hardware.
How to use it, step by step
- Click Start tuner and allow the microphone.
- Choose your instrument and (optionally) tap the string you are tuning.
- Pluck one string and let it ring.
- Tighten or loosen until the needle is centred and green.
Tips from the guide
- Tune in a quiet room and pluck one string at a time.
- Tune up to the note rather than down — it holds better.
- Tune every string, then re-check the first — tension changes the others.
- Use the reference tone to hear the target if your ear needs help.
Common mistakes to avoid
- Playing several strings together, which confuses any tuner.
- Tuning with a noisy fan or music playing.
- Forgetting to match the A4 setting to your ensemble.
Who uses it
- Guitarists, bassists and ukulele players. Quick, accurate tuning anywhere.
- Violin and cello students. Check open strings before practice.
- Singers and teachers. See the pitch you are singing.
How to ask a question people can answer
A good thread on the Online Tuner (Guitar, Ukulele, Violin & Chromatic) saves everyone time. Start with a title that names the exact problem, such as the input you used, the result you expected and the result you got. A title like “Not working” is hard to answer, while a title with the specifics gets replies quickly.
- Say what you tried. List the steps you followed and any settings you changed, so replies do not repeat what you already did.
- Share a small example. A short sample input and the output you saw is worth more than a long description. Remove anything private first.
- Mention your setup. Your device, browser and whether you are on a phone or a computer can explain many odd results.
- One question per thread. Separate topics get clearer answers and are easier to find later with the search box above.
- Come back and reply. If a suggestion worked, say so and upvote it, and if you found the fix yourself, post it for the next person.
