Online Chromatic Tuner: Tune Any Instrument Using Your Microphone
✨🎙️✨ Here's a simple chromatic tuner you can use as an instrument tuner. You
can also use this tool as a pitch detector. This tuner uses your device's
microphone to detect pitch and tell you which note is being played and if the
note is in tune.
🧑🎤 To get started, just click on 'Start Tuner' and give your browser permission to access your microphone. The tuner will then detect the pitch being received through the microphone and indicate the note with octave number as well as the number of cents above or under that note and the frequency in hertz.
🟢 The indicator will turn green (in tune) when the frequency is within +/- 5 cents to the note and will turn red-orange (out of tune) when the frequency is more than 20 cents over or under the note.
🤫 The tuner will be more precise in a quiet room with minimal amount of background noise.
🎵 This tuner uses concert pitch as its reference pitch, where A4 = 440 Hz. Here's a chart of note frequencies .
🎸 If you're looking to tune a guitar, bass guitar or ukulele, you can check out the guitar tuner, which will also auto-detect the string being played. Or, if you're looking to tune your voice, check out the voice tuner.
A word about how to use the chromatic tuner
The tuner detects the pitch being received by the microphone and converts the frequency value in hertz to a note name with octave.
The note name around the chromatic wheel will be highlighted and the indicator will let you know the note name, frequency in hertz and number of cents over or under that note. Cents are a unit of measure to measure frequencies between two notes. One semitone (aka one half step) is 100 cents, so there are 100 cents between any two adjacent notes on the chromatic scale.
The indicator or note name on the wheel will turn green when the note is in tune and will turn red-orange when the note is out of tune. The 'in-tune' range for this tuner is +/- 5 cents to the target pitch and the 'out of tune' range is anything more than 20 cents sharp or flat to the note.
When the sound is too noisy of muffled, the tuner will become inaccurate and default to F0.
When you're done tuning your instrument, you can click on 'stop tuner' and the tuner will stop the microphone access.
Hey 👋, I'm Seb and I'm creating muted.io
I need your help! If you have a few dollars to spare, I would be incredibly grateful if you could donate to support the development of muted.io. 🙏
I estimate that I would be able to fully support myself if only about 3% of the site's visitors made a one time $4 donation.
My ultimate goal is to be able to focus my time on creating more free musical tools, and your donation will go directly towards making that goal a reality. 🙌
