About this tool
This free online microphone test checks that your mic works, right in the browser. Allow access and speak — a live level meter and waveform show that your microphone is picking up sound and how loud it is. Nothing is recorded, saved, or uploaded; the audio never leaves your device.
How to use
- Click Start microphone test.
- Choose Allow on the browser permission prompt.
- Speak and watch the meter and waveform react.
- Click Stop when you're done.
Common uses
Checking a headset or webcam mic before a call or recording, confirming a new microphone works, troubleshooting why others can't hear you, or setting your input volume. Pairs well with the speaker test to check both sides of your audio.
Frequently asked questions
How do I test my microphone?
Click Start, allow microphone access when your browser asks, then speak. A live level meter and waveform respond to your voice, so you can confirm the mic is picking up sound and how loud it is.
Is my voice recorded or uploaded?
No. The audio is analyzed live in your browser only to draw the meter and waveform. Nothing is recorded, saved, or sent to any server.
The meter stays flat — what's wrong?
If speaking doesn't move the meter, check that the right microphone is selected in your browser and system settings, that it isn't muted, and that no other app (like a call) is holding it. Also confirm you allowed microphone permission for this site.
How do I allow microphone access?
When you start the test, your browser shows a permission prompt — choose Allow. If you blocked it before, click the camera/mic icon in the address bar or open site settings, set the microphone to Allow, and try again.
Can I choose which microphone to test?
The tool uses your browser's default input device and shows its name. To test a different one, set it as the default microphone in your operating system or browser settings, then restart the test.
Why does it need HTTPS?
Browsers only grant microphone access on secure (HTTPS) pages for privacy. This site runs over HTTPS, so the permission prompt will appear normally.
Does it work on phones?
Yes. It works in mobile browsers too — allow microphone access and speak, and the meter and waveform respond just like on desktop.
