Private by design. Audio is processed locally in your browser and never uploaded. There is no server for audio, nothing is recorded unless you press Record, and recordings are never stored: they live in this tab’s memory until you delete them or leave the page. Privacy
How to test your microphone
- Press Start mic test. Your browser asks for permission to use the microphone. Choose Allow.
- Talk. The meter should move while you speak and the verdict tells you if the level is working, too quiet or too loud.
- Record 10 seconds and listen to yourself. Pick another microphone in the list if you have several; the device name is shown below the list.
The page also has a background noise test (5 seconds of silence) and an echo test that plays a short tone and checks whether your microphone hears your speakers.
What the verdict means
| Verdict | Rule |
|---|---|
| Your microphone is working | Loudest level in the last 6 seconds is between −35 and −8 dBFS |
| Too quiet | Loudest level is between −65 and −35 dBFS (or you have not spoken yet) |
| Too loud | Loudest level is above −8 dBFS, or the signal reaches full scale and clips |
| No sound detected | Loudest level is below −65 dBFS: practically silence |
These limits are our own rule of thumb for speech picked up by a computer or phone microphone, not an industry standard. The level is measured in your browser in dBFS (0 = digital full scale). Our automated tests check the maths with hand-computed cases and a browser test feeds known sine waves into the page.
Mic not working?
If the meter stays flat or the browser shows an error, work through the guides: mic not working (browser blocked, muted, not found, Windows and Mac settings), mic too quiet and mic echo problem.
Frequently asked questions
How do I test my microphone online?
Press Start mic test and choose Allow when your browser asks. The level meter moves as you talk and the box under it tells you in plain words whether the microphone is working, too quiet or too loud. Press Record 10 seconds to hear yourself.
Is my voice uploaded or stored?
No. The test runs in your browser with the Web Audio API. The page has no audio upload, nothing is saved on a server and recordings are never stored: they stay in the memory of your tab until you delete them or close the page.
Why does my browser ask for permission?
Browsers only let a website use the microphone after you allow it, and only on https pages. You can take the permission back at any time in your browser’s site settings. When you press Stop, the page releases the microphone.
My mic test shows no sound. What now?
First check that the mic is not muted and is the selected device in the list above. If the browser says it is blocked, follow the steps that appear under the test. Still nothing? See Mic not working.
What does the number next to the meter mean?
It is the level in dBFS: decibels relative to digital full scale. 0 is the loudest signal the browser can deliver and quiet speech is far below that, so values are negative. It is not the loudness at your ear and not the same as dB SPL.
What level is good?
On this page the verdict is “working” when your loudest moment in the last few seconds is between −35 and −8 dBFS. That is our own rule of thumb for normal speech, not a standard. Quieter means too quiet, louder means too loud.
Why is the browser’s sound processing off by default?
Echo cancellation, noise suppression and auto gain can hide a weak or noisy microphone. With them off you see what the microphone really delivers. Tick the box to see how the mic sounds with processing, like many calling apps use.
Which browsers work?
Current versions of Chrome, Edge, Firefox and Safari support microphone access from web pages, on desktop and phones, as long as the page is on https and you allow the microphone.
