What the microphone test checks

The microphone test verifies browser permission, input device selection, live signal level, waveform movement, and short local playback. It is useful before calls, recordings, streams, classes, or support sessions.

The page requests microphone access only after you start the test. The live stream is used in the current browser tab for visual feedback.

How to get a useful reading

Choose the intended input device, speak at normal distance, and watch whether the level meter responds without staying pinned at the top. Use the short recording to confirm clarity, noise, clipping, or wrong input selection.

If you see movement but hear poor playback, check microphone gain, noise suppression, browser permission, and whether another app is using the device.

Privacy and local recording behavior

Recordings created by this page are temporary browser objects for local playback. They are not uploaded by the site and can be deleted from the page. Closing the page also clears the temporary playback object.

FAQ

Does the site upload microphone audio?

No. The microphone stream is used in the browser for the level meter, waveform, and local recording playback.

Why can't I see my microphone name?

Browsers often hide device labels until you grant microphone permission for the current site.

Why is the meter not moving?

The wrong input may be selected, permission may be blocked, the operating system input level may be muted, or another app may control the microphone.
