On this page: Quick answers about the voice range test and the other tools: how results are measured, why they vary, what happens to your microphone audio, and who runs the site.
Using the tools
Are the tools free? Do I need an account or an app?
Yes, they are free, and no account or download is needed. Open a tool in your browser and allow the microphone when asked. All tools are listed on the tools page.
Do the tools work on phones?
Yes. The tools are laid out for phone screens, and the main ones were tested at phone widths. Automated testing ran in Microsoft Edge; Safari, Firefox and physical Android phones have not been formally tested yet, so if something misbehaves there, please tell us.
Why isn’t the microphone working?
The browser must be allowed to use it. Check the site permission (the icon next to the address bar), close other apps that use the microphone, and avoid in-app browsers such as those inside social apps. If you blocked the microphone once, you have to allow it again in the browser settings.
Do I need a good microphone?
No. A phone or laptop microphone works for pitch and range. Quality matters less than a quiet room, a steady distance and a clear signal.
Vocal range, pitch and voice type
How does the voice range test measure my range?
The Voice Range Test listens through your microphone, estimates the pitch of your voice in the browser and turns it into a note name. A note only counts after you hold it steadily for about 0.8 seconds, so slides and cracks are ignored. You can also enter notes by hand.
What tuning do the tools use?
Standard equal temperament with A4 = 440 Hz, so A3 is 220 Hz and A5 is 880 Hz. The Pitch Detector lets you change the reference between 415 and 466 Hz.
Why does my range change between tests?
Your voice changes with warm-up, tiredness and time of day, and the reading changes with the room, the microphone and its distance. Compare results on the same device in similar conditions.
Why did the tool show the wrong octave?
A sung note has harmonics above the real pitch, and noise, breathiness or a very quiet voice can make the detector lock onto one of them. Sing a clear, steady note a little closer to the microphone and repeat it.
Is my range good? How many octaves should I have?
There is no target number. Control and comfort matter more than the span; see is a 2 octave range good for context.
Can a range test tell me my voice type?
Only as an estimate. The Voice Type Test compares your range with typical ranges, but professionals also listen to tessitura, tone, weight and register changes. The vocal range chart shows the typical range of each type.
How can I extend my range?
With regular, relaxed practice, not by forcing. Stop if it hurts. Try the vocal exercises to increase range and a warm-up routine first.
Privacy and safety
Is my voice recorded or uploaded?
No. The microphone tools analyse the sound inside your browser while the tool is running. They do not record your voice, and none of the tool scripts has code that sends audio or results to our server or anyone else. When you stop the tool or close the page, the audio is gone. See the privacy policy and data security.
Does the site save any results?
The microphone tools don’t save anything. The Vocal Range Calculator keeps your last five calculations in your browser’s local storage so you can see them next time. The Tone Generator, Audio Frequency Test, Online Metronome and Interval Ear Training keep a short history only until you close the tab. You can clear all of it in your browser settings.
Why do I see ads? Do they get my audio?
The site is free because it shows ads served by Journey by Mediavine, and Google Analytics counts visits. Ad partners may use cookies. They never receive your audio or tool results. The privacy link in the footer lets you manage ad choices. Details: cookies policy.
Is this a medical test? Should I keep going if singing hurts?
No and no. The tools can’t diagnose a voice or hearing problem. Stop if singing hurts, and see a qualified health professional about pain, lasting hoarseness or a sudden voice change. See the disclaimer.
About the site
Who runs VoiceRangeTest.com?
Harlow, who founded the site and runs it independently: they build and test the tools and write and edit the guides. More on the about page.
How accurate are the tools, and how are they tested?
Each tool is tested with generated notes of known pitch before release; the Pitch Detector, for example, read a 220 Hz tone as 220.0 Hz. Real voices and microphones add error, so treat results as estimates. Read our testing methodology and accuracy and limitations.
Do you use AI to write content?
AI may help with outlines or proofreading, but it is never used as a source, and Harlow checks and approves every page. See the editorial guidelines.
