Why run a microphone test

A microphone test confirms that your mic is active, permissions are granted, and the input level responds before calls or recordings. It is a quick way to spot muted inputs, wrong device selection, or low gain without installing software.

How the test runs

The tool runs in your browser and requests microphone access. When permission is granted, it visualizes live input levels as you speak, and it stops when you leave the page.

How to interpret results

The level meter should move when you speak at a normal volume. A flat meter usually indicates muted hardware, blocked permissions, or the wrong input device. Use the meter to confirm that the selected mic is responding consistently.

No movement suggests the browser is not receiving microphone input.
Very low levels can indicate low gain, distance, or a disabled mic.
Spikes or clipping may mean input gain is too high.

This test shows live levels only and does not record, store, or analyze audio quality or frequency response.
