Free Online Mic Tester
Microphone Test
Check whether your microphone is detected and sending sound to the browser. Start the test, allow mic access, then speak to watch the live input meter.
The test runs locally in your browser and is useful before a meeting, recording, stream, class, or support call.
Live input meter
Speak and see whether the microphone level responds.
Audio Check
Test microphone input before it matters.
Use the live meter to confirm that your browser can hear the selected microphone. If the meter stays flat, check permission and system input settings.
See input volume change as you speak, clap, or tap near the microphone.
Keep an eye on the highest level reached during the current session.
The tool checks level locally and does not save or upload audio.
How to use the microphone test
Click Start Mic Test and approve the browser permission prompt. Speak at a normal distance. A working microphone should make the live level meter move. If it does not, select the right input device in your operating system and check whether the browser is allowed to use it.
Microphone Test FAQ
Does this microphone test upload audio?
No. The page reads microphone level locally in your browser and does not upload recordings.
Why does the mic test need permission?
Browsers require permission before any page can access microphone input.
What should I do if the level does not move?
Check browser permission, operating system input settings, the selected microphone, and whether another app is using the device.
