Microphone test online — check mic level
Check your mic level in the browser — audio never leaves your device.
Start to open the mic and watch the level meter. Speak or tap the desk.
Level: 0%
Browser-only diagnostics. Grant permissions when the browser asks. Stop mic/camera when finished.
Mic access is local only while the test runs. We do not record or upload audio.

How the mic test works
With your permission we open the microphone via getUserMedia and show a live input level. Audio is not recorded or uploaded.
Stop the test to release the mic for Zoom/Meet.
How to use
Allow mic: Accept the browser prompt.
Speak: Watch the meter.
Stop: Release the device.
Fix OS: Change input if flatline.
People can't hear you on calls?
Wrong input device, muted OS, broken jack — isolate quickly.
Start the test, speak, and watch the meter move.
Practical tips
- Use HTTPS and allow permissions only when needed.
- Close other tabs that hold the device exclusive.
- Try another browser if the API is blocked.
- Share the link with support if a key or button fails.
- Pick the correct input in OS sound settings.
- Stop the test before joining a call.
