This range session listens for notes you can hold clearly, guides you from a comfortable low note to a comfortable high note, and ignores momentary noise. The result includes your measured span and an honestly hedged voice-type estimate; range alone cannot determine tessitura, timbre or passaggio.
A range you can actually repeat
Many microphone tools treat any detected blip as an extreme. This one confirms a note only after sustained, high-clarity input and rejects implausible vocal pitches, making the final span more useful for practice.
Use the instrument
- Allow the microphone. Start from the instrument and approve microphone access. Audio is analysed on this device and is never uploaded.
- Sing a steady tone. Use a comfortable vowel and hold the note. The detector waits for a clear, stable signal instead of counting breaths or squeaks.
- Follow the live feedback. Read the note, frequency, cents and visual shape together. Range mode guides you low then high; the other modes focus on one practice job.
- Stop when you are finished. Stopping releases the microphone immediately. Range results can be saved locally or shared as a generated image without an account.
Frequently asked questions
Does this vocal app record or upload my voice?
No. The microphone signal is analysed inside your browser and is not recorded, uploaded or sent to an API. The app only stores settings and completed range summaries locally on your device, and you can clear those at any time.
Why does the detector ignore some sounds?
That is intentional. Breathing, handling noise and very brief squeaks are unreliable pitch evidence, so the detector requires a clear signal and the range test requires a note to be sustained before it can change your measured low or high note.
Will it work on a phone?
Yes, in a modern mobile browser with microphone permission. On iPhone and iPad, reference tones may be muted by the hardware silent switch even while microphone detection works, so every audio cue is paired with a visible cue.
How should I take the vocal range test?
Start near speaking pitch, slide down gently and sustain your lowest comfortable clear note. Advance when the low side has settled, then slide upward without forcing and hold your highest comfortable clear note. Stop if anything feels strained.
