Mic Test
Check your microphone with a live input-level meter and waveform — no recording.
Level—
StatusIdle
Audio is analysed live in your browser with the Web Audio API only to draw the meter and waveform. Nothing is recorded or uploaded, and the microphone is released the moment you stop.
How to test your microphone
Click Start and allow microphone access when your browser asks. Speak normally — the level meter rises with your volume and the waveform moves with your voice. If both react, your mic is working. Click Stop to release it.
If nothing moves
Check that you picked the right microphone in your browser's permission prompt and that it isn't muted in your system settings. The page can only read whatever device your browser hands it, so the OS-level input must be active.
Questions
Is my microphone recorded or uploaded?
No. The audio is analysed live in your browser using the Web Audio API only to draw the meter and waveform. Nothing is saved, recorded, or sent anywhere, and the stream is released the moment you stop.
Why is the browser asking for permission?
Browsers require your explicit permission before any page can access a microphone. You'll see a prompt the first time — choose Allow and pick the device you want to test. You can revoke it any time in your browser settings.
The meter isn't moving — what's wrong?
Make sure the correct mic was selected in the permission prompt, that it isn't muted at the system level, and that no other app has exclusive control of it. Reload the page and try Start again if needed.
