Is your microphone
coming through?
Check your input, see its live signal, and hear yourself back.
No account. No upload. Just your microphone.
Microphone test
Ready when you areConnect your microphone, then start the test.
The ring follows your input level.
Digital levels (dBFS), not calibrated sound pressure. A quiet signal alone does not mean your mic is broken.
Hear yourself back
Record up to 10 seconds. Use headphones to avoid feedback.

The browser won’t allow microphone access
Open the site permission control beside the address bar and allow microphone access. Then check your operating system’s privacy settings. In an embedded browser, open this page in a normal browser tab if microphone access is unavailable. Chrome, Edge, Firefox and Safari require a secure page (HTTPS).
The meter is moving, but a call still cannot hear me
This test confirms that this browser receives your selected input. Your meeting or recording app may use a different microphone. Select the same device inside that app and check its mute and input settings.
For Zoom, use the browser-versus-Zoom checklist.
The signal is quiet or distorted
Move closer and check the microphone’s input gain. Speak normally while watching the meter. Peaks close to 0 dBFS can clip; lower the gain if the clipping warning appears. Noise processing and gain settings can differ between browsers and applications.
No microphone appears in the list
Reconnect the device, check its power, and confirm that the operating system detects it. Close another app if it is using exclusive device access. Grant this page microphone permission, then start the test again.
How private is the recording?
Signal processes audio in your browser. It does not upload audio, recordings or microphone names. Delete the recording or close the tab to clear the app’s copy. A recording you download remains on your device. Hosting still involves ordinary technical connection data; see the privacy notice.

- Connect your microphone or headset and select “Start microphone test”.
- Allow microphone access, select the input, and speak at your normal distance.
- Look for a moving signal and choose “Record 10 seconds” to check playback.
- Stop the test when finished. If the result differs in another app, compare its selected input and gain.
