In short: VoiceRangeTest.com is a free voice range test plus a set of browser-based pitch, note and practice tools, with guides that explain what the results mean. Nothing to install, no account, and your microphone audio is analysed on your own device. The site is independently run by Harlow.
A tool can tell you a note name in a second. The harder part is knowing what that note says about your voice. VoiceRangeTest.com was built to give both: a quick, honest measurement and the context to read it, without presenting a browser reading as more precise or final than it is.
What you can do here
Every tool is free and runs in a modern browser on a phone, tablet or computer. The complete list is on the tools page; the main ones are grouped below.
Measure your voice
- Voice Range Test
Sing your lowest and highest steady notes to see your range, octave span and closest voice type. You can also enter notes by hand.
- Voice Type Test
Compares your range with soprano, mezzo, contralto, tenor, baritone and bass, and says when you sit between two types.
- Voice Hz Test
Reads the average pitch of your speaking voice in hertz.
Find pitch and notes
- Pitch Detector
A live tuner-style display of the note, frequency and cents while you sing or play.
- Note Identifier
Names each note on a staff and keyboard, from the microphone or an audio file you choose.
- Pitch Accuracy Test
Sing back target notes and get a score based on how many cents you land from each one.
Plan and practise
- Vocal Range Calculator
Type two notes to get the span in semitones and octaves, with no microphone needed.
- Vocal Range Chart
The typical range of each voice type on one chart, with a text legend.
- Interval Ear Training
Listening drills for recognising intervals.
- Tone Generator
Plays a steady reference tone at any frequency.
Alongside the tools, the site publishes guides on vocal range, voice types and technique, such as the types of vocal ranges and what tessitura means, plus singer vocal-range analyses that separate a singer’s usual range from rare extreme notes.
Who runs VoiceRangeTest.com
The site is founded, written and maintained by Harlow, who works on it independently. Harlow builds and tests the tools, researches and edits the guides, and reads the correction reports and messages that come in.
Harlow does not list professional titles or qualifications on this site. Instead, the site shows its work: how each tool was tested, which numbers came out, what has not been tested yet and where a result can mislead. You can check that evidence below and on the linked pages.
How the tools are built and tested
Before a tool version goes live it runs through an automated test suite in a clean WordPress install, in a headless Microsoft Edge browser fed with a simulated microphone. Instead of a real voice, the tests play generated audio with known answers: steady notes at exact frequencies, notes a set number of cents sharp or flat, vibrato, silence, noise and a refused microphone permission. Layouts are checked at phone widths of 360 to 390 pixels.
| Tool (version) | How it works | Checks passed | Example test signals |
|---|---|---|---|
| Voice Range Test 2.0.0 (homepage) | YIN pitch engine; a note counts only after about 0.8 s of steady singing; manual note entry C2–C7 | 32 | Synthetic glide A2→E4, silence, noise |
| Pitch Detector 2.0.0 | YIN with a clarity gate and a 3-reading median; A4 reference adjustable from 415 to 466 Hz | 35 | A3 220 Hz read as 220.0 Hz; A4 +20 cents read as 445.1 Hz (+20 cents); C7 read +1 cent |
| Note Identifier 2.0.0 | Same engine; can also read an audio file you choose, inside your browser | 28 | A 16-note melody with vibrato: all 16 notes found in order |
| Pitch Accuracy Test 2.0.0 | 100 points within 5 cents of the target, falling to 0 at 50 cents | 40 | Voices 15 cents flat and 35 cents sharp, vibrato, silence, noise |
| Voice Type Test 2.0.0 | Compares your range with the site’s published ranges (e.g. tenor C3–C5, baritone A2–A4) | 33 | Held A2 and E4, silence, noise, permission denied |
| Voice Hz Test 1.0.0 | Average speaking pitch in Hz | 27 | Synthetic speech at 119.4 Hz and 208.9 Hz |
| Vocal Range Chart 1.0.0 | Chart drawn on the server as an SVG with a text legend, so it works without JavaScript | 52 | Seven voice types, comparison views, phone layout |
Testing also finds real bugs. The Voice Type Test once called a range “tenor” while its own chart showed tenor and baritone as an equal match; it now says “between tenor and baritone”. The Pitch Accuracy Test’s microphone level bar never moved because of a shared code hook; it was fixed and two regression checks were added. The full process is described in our testing methodology, and the limits of browser measurement in accuracy and limitations.
How the guides are written
Guides start from established music theory, acoustics and voice-teaching sources, and from direct use of the site’s own tools. Singer range articles compare recordings and references rather than copying the widest number found online. Estimates, reported values and disputed claims are labelled as such. AI software may help with outlining or proofreading, but it is never treated as a source, and Harlow checks and approves what is published. Details are in the editorial guidelines.
Your microphone and your data
Microphone tools analyse sound inside your browser with the Web Audio API. They do not record your voice, and none of the tool scripts contains code that sends audio or results anywhere. The Vocal Range Calculator keeps your last five calculations in your browser’s local storage; a few practice tools keep a short history only until you close the tab. Read the privacy policy and the data security page for the full picture.
How the site is funded
VoiceRangeTest.com is free because it shows display ads served by Journey by Mediavine. Google Analytics measures visits. The site has no affiliate links. Advertisers have no say in what is written or in any tool result, an ad is not an endorsement, and the tools never pass audio or results to an ad or analytics script. Privacy choices for ads, including the US opt-out, are in the privacy link in the site footer.
Education, not medical advice
The tools and guides are for learning and self-assessment. They cannot diagnose a voice or hearing problem. Persistent hoarseness, pain or a sudden change in your voice needs a qualified health professional. See the disclaimer.
Independence
VoiceRangeTest.com is not the official site of any singer, label, school or organisation it mentions. Names of singers and songs are used to inform and teach.
