Hold each note steadily for a moment so it can be captured.
Sing your lowest comfortable note, then your highest, holding each one steadily — the tool records your minimum and maximum pitch and shows your range in octaves and semitones, plus a rough voice-type estimate (bass, baritone, tenor, alto, mezzo-soprano, soprano). Pitch is detected with browser autocorrelation entirely on your device — nothing is recorded, uploaded or sent anywhere. Voice type is only a rough guide; real classification also depends on tessitura and timbre.
A free online vocal range test that works in your browser using your microphone. Tap "Start microphone" and allow access, then sing your lowest comfortable note and hold it, then sing your highest note: autocorrelation pitch detection captures only steady pitches and records your minimum and maximum note automatically. Your range is shown in octaves and semitones (for example 2 octaves 4 semitones = 28 semitones), along with a rough voice-type estimate (bass, baritone, tenor, alto, mezzo-soprano, soprano) plotted against a chart of typical voice ranges so you can see where your voice sits. Hold each note steadily for a moment for an accurate reading, and press Reset to start over. It's handy for finding songs in your key for karaoke, tracking vocal warm-ups and singing practice, or just getting a guide to your voice type. All microphone analysis happens entirely on your device, inside the browser — nothing is recorded, stored, uploaded or sent to a server. Voice type is only a rough guide; real classification also depends on tessitura and timbre. No install, no sign-up, free to use.

FAQ
Is my microphone audio uploaded?
No. Pitch detection runs entirely inside your browser — the microphone audio is never recorded, stored, uploaded or sent to a server. Everything is local.
Is the voice-type result accurate?
The voice type (bass to soprano) is a rough estimate based on your measured range fitted to typical voice ranges. Real classification also depends on your comfortable range (tessitura) and timbre, so treat it as a guide.
What if my range isn't being captured?
Hold each note steadily for a moment. Brief sounds and background noise are unlikely to be recorded. A quiet room and getting closer to the mic improve accuracy.
Does it work on a phone?
Yes. It works in any browser on phone or computer once you allow the microphone. No app install or sign-up is required.
What do the octaves and semitones mean?
They describe the span from your lowest to your highest note. For example, "2 octaves 4 semitones (28 semitones)" counts the width of your range where 12 semitones make one octave.
