Good
The meter rises clearly when you speak at normal volume, falls back when you stop, and never sits pinned at the top. Your input chain is healthy.
Microphone Tester
Check microphone permission, choose an input device and monitor the live input level in your browser. Use the meter to confirm whether your laptop mic, headset mic or USB microphone is actually sending signal.

About the microphone test
The microphone test displays a live level meter driven by your selected input device, so you can see at a glance whether your voice is reaching the computer. Speak normally and watch the meter: movement means the microphone, its cable, the port and the drivers are all doing their job.
Audio is analysed entirely inside your browser to draw the meter — nothing is recorded, stored or uploaded. The page uses the same Web Audio machinery that meeting apps use, which makes it a faithful stand-in: if the meter moves here, your mic will work in a call once the right device and permissions are selected there.
Most "my mic doesn’t work" problems turn out to be selection problems rather than hardware ones. Laptops commonly expose several inputs — the built-in array, a headset mic, sometimes a monitor or webcam mic — and apps happily pick the wrong one. The device list on this page shows exactly what your browser can see, which is often all you need to spot the mistake.
Understanding microphone level
The level meter shows whether your browser receives an audio signal from the selected microphone. It does not record your voice or send audio to the server.
What this test checks
- Microphone permission for this site and browser session.
- Input device selection after the browser reveals available microphones.
- Live signal level based on the microphone waveform measured locally.
- Whether the selected input is silent, clipping, too quiet or responding normally.
How to understand your results
- A good result shows the meter rising when you speak and falling when the room is quiet.
- A low but visible signal usually means the mic works but gain, distance or input selection needs attention.
- A constantly high meter can indicate background noise, boost settings, a noisy headset cable or the wrong input source.
- If the meter never moves, check permission, mute switches, OS privacy settings and whether another app has exclusive control.
Common problems and fixes
No input level
Choose another input device, check physical mute switches, and confirm the operating system allows browser microphone access.
Very quiet microphone
Move closer, raise input gain in system settings, and avoid plugging a headset into the wrong combined audio jack.
Distorted or clipping audio
Reduce microphone boost, lower input gain and retest while speaking at a normal volume.
Wrong microphone selected
Laptop arrays, headset mics and monitor mics can all appear. Pick the device closest to your mouth.
FAQ
Is my audio uploaded?
No. The page uses local browser audio analysis to draw the meter and does not upload or save microphone audio.
Why is there a delay before device names appear?
Browsers commonly hide detailed device names until you grant microphone permission.
What level should I aim for?
Normal speech should produce visible movement without staying pinned at the top of the meter.
Why can people not hear me in calls even though the meter moves here?
Your mic works — the meeting app is using a different input. Open its audio settings and select the same device that moved the meter on this page.
How do I test a headset microphone?
Connect the headset first, grant permission, then choose the headset entry in the device list. On combined 3.5 mm jacks, make sure you used the headset port, not the headphone-only one.
Why does my Bluetooth headset sound worse when the mic is active?
Bluetooth switches to a lower-quality profile when the microphone is in use — that is a protocol limitation, not a fault. Wired headsets avoid it entirely.
