Testing a mic on Windows and Mac
Any of these tells you whether the microphone works. If it works here but not in Zoom, Teams or Discord, the microphone is fine: choose the same input in that app’s audio settings.
- In your browser: open the Microphone Test, allow microphone access and speak. If the meter moves with your voice, the browser is receiving sound from that microphone. To hear how you sound, use the Mic Test with Playback.
- In Windows 11: select Start > Settings > System > Sound and choose your microphone under Input. Select it, then use Start test under Microphone test and speak.
- On a Mac: choose Apple menu > System Settings, click Sound, then Input. Select the microphone and watch the input level move while you speak.

Before you start
- Allow microphone access when the browser asks. You can revoke it at any time in the browser settings.
- Audio stays in your browser. It is never uploaded or stored.
- If the meter stays flat, check that the right microphone is selected in your system settings and is not muted.
Frequently asked questions
How do I test my microphone?
Open the Microphone Test, allow microphone access and speak. The meter should move with your voice. If it stays flat, choose another microphone from the list, and check that it is not muted in your system settings or on the headset.
Why does my browser not ask for microphone permission?
It was probably blocked earlier. Click the icon next to the address bar, allow the microphone for this site and reload the page. Browsers also allow microphone access only on secure (https) pages.
Is my audio recorded or uploaded?
No. The level meter works on the live signal inside your browser. The recording test keeps its clip in memory on your device, and nothing is sent to a server.
