What does a microphone test check?
After you grant permission, the browser receives microphone input and displays its changing level so you can check whether sound is reaching the page.
This meter is not a recording or a quality assessment; stop the test when you finish to release the microphone.

Browser Microphone Permission and Input Levels
A browser microphone test checks whether a web page can access an input device and receive changing audio levels. The browser asks for permission because microphone access is sensitive; access generally requires a secure HTTPS page or localhost and can also be blocked by operating-system privacy settings. A moving level meter indicates that some sound is reaching the browser, but it does not measure microphone fidelity, remove echo, or prove that a meeting app has selected the same device. This is useful before a call, lesson, or recording session. Check the operating-system input selection and browser site permissions if no activity appears, then stop the test to release the microphone. The page measures input locally and does not create an audio recording.
Key Features
💡 Pro Tips
- →Speak at your normal distance and volume, and check the selected input device in browser and system settings.
- →Use HTTPS or localhost, grant permission only when prompted, and stop the test after checking.
Common Mistakes
Assuming a permission prompt guarantees the microphone is working
Permission only allows access; a muted device, wrong input selection, disconnected headset, or system privacy setting can still prevent usable sound.
Leaving the microphone stream active after testing
Stop the test when finished so the browser releases the device and the microphone indicator turns off.

Frequently Asked Questions
Why does the browser ask for permission?
Web pages must obtain explicit permission to access a microphone, and this feature generally requires HTTPS or localhost.
Does the tool record my voice?
No recording is created. The page measures input level locally to show whether audio is reaching the browser.
Why does the level meter not move?
Check that the intended microphone is selected, unmuted, and allowed in browser and system privacy settings; also speak close enough for the device to pick up sound.
Can this test tell whether my microphone sounds clear on a call?
It only shows local input activity. It does not evaluate call-app settings, network quality, echo cancellation, or how other participants hear you.
