Online Voice Tuner: Tune Your Singing Voice
🎤 Here's a simple online voice tuner that makes it easy to tune your singing
voice and practice hitting different notes. This voice tuner uses your
device's microphone to analyze the frequency being played and tell you if
you're on the note.
🟢 Start the tuner by clicking on 'Start Tuner' and giving your device
microphone access. Start holding a note and the tuner will let you know which
note you're playing and let you know if you are sharp or flat.
🎶 Try hitting a note and holding it within the 3 center vertical lines. The
closer you are to the center, the more exactly on the note you are.
🔧 For more tuning tools, check out the
chromatic tuner and the
guitar tuner.

More about this online voice tuner
This tuner analyzes the frequency via a microphone input to detect the pitch. When I note is detected it will be indicated along with a vertical bar that indicates how on the note that particular pitch is.
🎹 You can tap the keys on the piano keyboard diagrams to give you a reference tone.
✅ When the moving vertical line falls between the 3 fixed center vertical lines, the vocal note held is in tune. The in tune range is within about 12-15 cents of the note. The indicator will be green when in tune, yellow when just slightly out of tune and red when out of tune.
🤫 The voice tuner can be sensitive to ambient noise, so try to use it in a quiet room.

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. 🙌
