Vocal Frequency Range Tool
Sing your lowest and highest comfortable notes into your microphone. The tool maps your range in musical notes and Hz, estimates your voice type, and shows a few famous-singer examples.
ℹ Hold each note steadily for a moment so it registers (brief glitches are ignored). Your range depends on warm-up, technique, health, and time of day, so this is a snapshot, not a verdict. Voice-type classification is approximate — real classification also considers tessitura and timbre, not just range. Your mic is analyzed live and never recorded or uploaded.
How It Works
The tool detects the pitch of your voice in real time with the YIN algorithm and converts it to a musical note. As you sing, it remembers the lowest and highest notes you hold steadily — a short stability check means a sustained note counts but a passing squeak or click doesn’t. Your range is the distance between those two notes, shown in note names, Hz, and octaves. The voice type is a best-fit guess: it compares the centre of your range to the typical ranges of bass, baritone, tenor, alto, mezzo-soprano, and soprano voices. Everything runs live on your device; nothing is recorded.
Treat the result as a fun snapshot. Your usable range shifts with warm-up, technique, vocal health, and the time of day, and trained singers extend it with falsetto, head voice, and whistle tones. Real voice classification by a teacher weighs tessitura (where your voice sits comfortably) and timbre, not just the extremes — so two people with the same measured range can be different voice types. The famous-singer examples are rough associations, not exact matches.
