About Mic Test
A microphone test shows whether a microphone is connected, allowed, and picking up sound. After you grant permission, the page reads the input through a Web Audio analyser and moves a level meter as you speak, with the device name and the highest peak so far as a percentage. Audio is analysed in the browser only and is never recorded, played back, or uploaded. It uses the default microphone and needs a secure (HTTPS) connection.
Questions about Mic Test
Why does the meter not move when I speak?
The browser may be listening to a different input from the one you are using. Check the default microphone in your system sound settings, make sure a hardware mute switch is off, and raise the input volume, then restart the test.
Can I hear a recording of my voice?
No. The page only measures the signal level and does not record or play back audio. A peak near 100% while speaking normally suggests the input gain is too high and your voice may sound distorted to others.
