Vocal range test. Explore your comfortable notes.
Use your microphone to capture a comfortable low and high note, then see the approximate span between them. Pitch detection runs locally and can make mistakes; repeat and listen before relying on a result.
Test your vocal range
Free · localStart the microphone and sing one steady note in a quiet room. This is an estimate from roughly 80–1,000 Hz, using A4 = 440 Hz. The microphone is not played through your speakers.
Current estimate
The microphone is off.
Sing a low note you can sustain comfortably, then capture it. Repeat for a comfortable high note. You can replace either reading; do not strain.
Low: not captured · High: not captured

How to test your vocal range online
Use comfortable sustained notes and repeat the test. The readings are approximate and do not classify your voice.
- 01 / START
Allow microphone access
Start the monitor and grant browser permission. Choose a quiet room, avoid playing accompaniment into the microphone, and warm up comfortably.
- 02 / LOW
Capture a comfortable low note
Sing one steady note at the lower end of what you can sustain comfortably. When the display settles, choose Capture low note. If it looks wrong, repeat and replace it.
- 03 / HIGH
Capture a comfortable high note
Repeat for a comfortable high note. Compare the displayed notes and approximate semitone span, then stop the microphone. Do not push for an extreme note.

What the vocal range test can tell you
The span is the number of semitones between the nearest equal-tempered notes at your two chosen moments. Twelve semitones make an octave. For example, C4 to C5 is 12 semitones. The displayed span rounds both endpoints to the nearest note and is not a precise measurement of every frequency between them.
The detector looks for one periodic signal between approximately 80 and 1,000 Hz, using A4 = 440 Hz. Noise, harmonics, vibrato, other voices and device processing can cause missing notes or octave errors. Some comfortable notes may be outside this tool's range. Compare by ear, try more than once and replace a reading if it is clearly wrong. The pitch monitor shows the same estimate without capturing endpoints.
Two captured notes are a snapshot, not a diagnosis, your complete usable range, a vocal classification or a measure of singing ability. The vocal range guide explains how to repeat the check and compare it with a song. Range can vary with the day, technique and context. A singing teacher can help you explore it comfortably; stop if singing feels uncomfortable.
Use the reading as a starting point
Check your microphone and reference notes
If the display does not respond, verify browser permission and use the microphone test to check input. The tone generator can create a separate reference for a note; lower playback volume first and keep it out of the microphone while measuring your voice.
The test analyzes live input in the browser. It does not record or upload audio, play the microphone through your speakers, or save your readings. Stop the microphone when finished.
A few useful answers
Free vocal range test questions
How do I test my vocal range online?
Start the microphone and allow access. Sing a comfortable sustained low note and capture the displayed reading; then do the same for a comfortable high note. The tool shows the nearest notes and approximate semitone span. Repeat and check the readings by ear.
Does the test record or upload my voice?
No. It analyzes live microphone samples locally in the browser without recording or uploading them. Stop the microphone when finished; captured readings disappear when you leave or clear them.
Does the result show my complete vocal range or voice type?
No. It only compares two moments you choose, not your full capability or a voice classification. The detector attempts approximately 80–1,000 Hz and can miss notes or make octave errors. A teacher can help assess usable range in context.
What if the note is wrong or unstable?
Try one sustained note in a quiet room without accompaniment and check the microphone. Background sounds, harmonics, vibrato or device processing can cause a wrong or missing result. Recheck by ear and capture again; do not strain to reach a number.
What does the semitone span mean?
It is the distance between the two nearest equal-tempered notes, using A4 = 440 Hz. Twelve semitones equal one octave. It is rounded to notes, so it is not an exact measurement of your frequency range or singing ability.
