What note and pitch are you actually hitting?
Sing a note, and this tool tells you what it is. You'll see the note name, the frequency in Hz, and how close you are to the center of that note. Everything updates live while you sing.
Just turn on your mic and start. Hum a note, sing part of a song, or play a note on guitar or piano. The tool shows you the note as soon as it detects a clear pitch.
Also you'll also see a graph that tracks your pitch over time. Hover over any point and it shows you the exact note, the Hz, and how many cents off you were. This is a great way to actually see your voice work, not just hear it.
Sing a scale and watch each note show up as you go up. Hold one note and see how steady you can keep it. Watching the graph move can help you understand your pitch in a way that's difficult to get from listening alone.
There's no limit on how much you can use it. It's free, with no sign up and no time limit. Use it every day if you want — it's a simple tool you can come back to whenever you're practicing.
To get the best reading, use a reasonably quiet room. Keep music or fans away from the mic, and avoid talking directly into it while testing.
What Hz and Cents Mean
Hz just means how fast the sound is vibrating. A higher frequency means a higher pitch, while a lower frequency means a lower pitch. For example, 440 Hz is approximately the musical note A4.
Cents tell you how close your pitch is to the center of the note. 0 cents means you're right on the note. A positive number means you're a little sharp, while a negative number means you're a little flat. If you want help correcting your pitch while you sing, try our Vocal Tuner.
Frequently Asked Questions
Why would I need a pitch detector?
If you want to know what note you're actually singing or playing, this gives you a straight answer instead of a guess.
Will this always show the right note?
Most of the time, yes. But noise or a shaky note can throw it off for a second. If that happens, just try again.
Why is it showing the wrong note?
Usually it's background noise, a note that changed too fast, or your voice being too quiet. Get closer to the mic and find a quieter spot.
How can this help me get better at singing or playing?
It shows you the truth your ear might miss. You can check if you’re flat or sharp, and practice holding a note steady until it matches.
What instruments can I use?
You can try with these instruments — guitar, piano, ukulele, violin, or your voice. It won't read chords, just single notes.
Do I need any special gear?
No. Your normal mic is fine. Just try to find a quiet spot for the best result.
