Microphone Test
Microphone Test checks your mic in the browser with a live level meter, clipping warning, waveform and a 5-second sample to play back, without recording or uploading.
Nothing is recorded to a file or uploaded. The sample stays in this tab's memory.

This page checks that your microphone works before a call, a recording or a class. It shows how loud the input is, warns when it clips or is too quiet, draws the sound as you speak, and records a 5-second sample you can play back. It also lists what the browser reports about the mic, and lets you switch off its echo cancellation, noise suppression and auto gain to hear the difference. Everything stays in your browser: nothing is recorded to a file or uploaded.
How to use it
- Press Test my microphone and allow access when the browser asks.
- Speak normally. The meter should sit in the middle when you talk, not hit the red at the end.
- Pick another microphone from the list if the meter stays still.
- Press Record 5-second sample, say a sentence, then listen back.
Need to keep a recording?
This test never saves anything. To record a voice note, a lecture or a meeting and download it, use the Voice Recorder, which also runs in your browser without uploading. To check your camera too, try the Webcam Test.
Frequently asked questions
Is my microphone audio recorded or uploaded?
No. The level meter and waveform are worked out in your browser from the live input. The 5-second sample is held in this tab's memory only, so you can play it back, and it is gone when you leave or reload the page. Nothing is sent to a server.
How do I know if my mic is working?
Press Test my microphone and allow access. If the level meter and waveform move when you speak, the browser is getting sound from it. Then record the 5-second sample and play it back to hear what other people would hear on a call.
The meter doesn't move. What should I check?
First pick the right microphone in the list: laptops often have a built-in mic, a headset and a webcam mic, and the default may not be the one you speak into. Then check for a hardware mute switch on the headset or cable, and the input volume in your system sound settings (on Windows, Settings > System > Sound > Input; on a Mac, System Settings > Sound > Input).
What do echo cancellation, noise suppression and auto gain do?
They are processing your browser applies to the microphone before a web page gets it, and video call sites in the browser usually ask for all three. Echo cancellation removes sound from your speakers that the mic picks up, noise suppression dims steady background noise like a fan, and auto gain control raises or lowers the level to keep your voice even. Turn them off here, record a sample each way, and you can hear what they change.
What does the clipping warning mean?
The signal hit the loudest value the input can carry, so the tops of the waveform were cut off. It sounds harsh or crackly. Move a little further from the mic, speak a bit softer, or turn the input volume down in your system sound settings.
It says my microphone is in use by another app.
On some systems, Windows especially, a microphone can only be opened by one app at a time. Close Zoom, Teams, Discord or other tabs that use the microphone and try again, or pick a different microphone.
Will this fix my microphone in Zoom or Google Meet?
It tells you whether the microphone works and sounds right in this browser, which is what Google Meet and the browser versions of Zoom and Teams use. Desktop apps choose their microphone in their own settings, so if this test works but a desktop app doesn't, check the input device chosen in that app.
