Vocal Range Finder
- 1 Comfortable low
- 2 Comfortable high
- 3 Your range
Use one clear sound in a quiet room. Your audio stays in this browser.
Warm up gently. Save only notes you can repeat comfortably; stop if singing feels strained.
Reference ranges overlap. These comparisons describe note-range similarity, not a definitive voice classification, probability or assessment of tessitura and tone.
Settings & measurement notes
Microphone input is analyzed in memory; audio is never recorded or uploaded by this plugin. Stopping, hiding or leaving the page releases the microphone. Reference tones temporarily pause analysis.
Pitch estimates can be affected by breathy or irregular sounds, harmonics and microphone processing. This is a single-note tool, not a medical or professional voice assessment.
A4 defaults to 440 Hz. One octave doubles frequency; one semitone is 1/12 of an octave. The detector uses the McLeod pitch method with clarity and stable-note filtering.

Use the Vocal Range Finder when you do not yet know the note names at the comfortable edges of your singing voice. It guides you through a low endpoint and a high endpoint, with live note feedback, stable capture and manual entry. The result documents a span you can check again, rather than automatically discovering every sound your voice can produce.
Locate the low end first
- Begin after a gentle warm-up in a comfortable register.
- Select microphone mode, start input and allow access.
- Sing a clear easy note, then move down gradually.
- Hold a repeatable low note while the stability indicator fills.
- Save it and verify its octave before continuing.
Do not begin by forcing the lowest possible sound. An irregular low effect can be difficult to track and may not represent a useful singing endpoint. The detector cannot decide whether your production felt comfortable.
Find and verify the high end
Move upward from a manageable region and stop before the task feels strained. The hold tracker asks for about 0.7 seconds of stable input before a note can be captured. That condition rejects some short spikes, but it does not certify technique or comfort.
Save the high endpoint, then check the pair together. If one note looks an octave away from what you expected, listen again and redo that step. A strong harmonic can make a tracker jump to a different register even when your intended note did not change.
The Note Detector is useful for a separate single-note check. Keep accompaniment and external reference playback from competing with your own voice.
Manual entries can complete a known result
If you already know the endpoints from an instrument or another checked source, enter them manually. Include the octave and keep the high note above the low one. Reference playback can help locate a selected pitch.
A manual calculation describes the notes you chose, not a new microphone measurement. Save that origin with the result. Use the Vocal Range Calculator for a focused known-note workflow and the main Vocal Range Test for the site’s complete starting guide.
Understand what the interval says
The range is the difference between endpoint MIDI numbers. Twelve semitones make one octave. For example, B2 is MIDI 47 and D5 is MIDI 74, giving 27 semitones or 2.25 octaves.
Counting both endpoint note positions is different from counting interval steps. The tool reports distance, not the number of named notes you can list inclusively. A fractional octave is simply a span that extends beyond a whole number of twelve-semitone groups.
The frequency values use the selected A4 reference. Changing that reference changes calculated endpoint frequencies, but it does not add new notes to the voice or verify manually selected endpoints.
Compare the span without overclassifying it
The reference results compare your endpoints with illustrative voice spans. Several can overlap substantially with your range. A match percentage expresses interval overlap, not the probability of a professional classification.
The Voice Type Test explains the role of tessitura and other context. A singer who can briefly reach a high endpoint may still find a melody uncomfortable if it stays there for many measures.
Likewise, a range does not show how smoothly you cross registers, how long you can sustain notes or how you shape a phrase. Keep the result focused on the specific low-and-high task you performed.
Make the search repeatable
Use the same microphone, distance, tuning reference and general warm-up conditions for later tests. Repeat an endpoint a few times gently before accepting it. Do not interpret a one-semitone day-to-day difference as a complete assessment of progress or decline.
If the input is weak, check permission and microphone selection before raising your voice. Calibrate room noise while quiet, and avoid setting the gate so high that ordinary soft input disappears. A loud clipped signal is not necessarily easier to interpret.
Speak-frequency measurements answer a different question. The Voice Frequency Test summarizes the pitches used in a short task, rather than searching for comfortable singing endpoints.
Use the result for the next decision
Choose a short melody and compare its actual notes with your verified span. Then check where the melody spends most of its time. Range inclusion alone does not establish that its tessitura, register or style suits you.
The Octave Range Test helps interpret the distance. For tuning individual targets inside the span, the Pitch Test provides a separate accuracy exercise.
Copy and CSV preserve calculation information, not audio. Microphone input is analyzed locally in memory by the plugin and is not recorded or uploaded. Stop or leave to release input, and keep useful results before resetting.
Frequently asked questions
Will it automatically scan my whole voice?
You deliberately choose and capture comfortable endpoints. The tool does not force or verify every possible note between your extremes.
Why does a brief high squeak not make a useful endpoint?
A range baseline should use repeatable comfortable singing. A short or uncertain extreme may not represent that task.
Can I enter notes instead?
Yes, but manual input is a calculation from your choices rather than confirmation that you sang them.
Does the closest reference name settle my voice type?
No. Range references overlap and do not capture tessitura, tone or register behavior.
