Check that your microphone works, with a live level meter, waveform, playback recording and a clear verdict
How to use
Press Test my microphone and allow access when your browser asks.
Talk normally. The level bar and waveform move with your voice, and the box at the top tells you whether the microphone is working.
Press Record 5 seconds, then play it back to hear exactly how you sound.
If it is too quiet, too loud or silent, follow the advice shown, or pick a different microphone from the list.
Why use this tool
A clear answer, not just a squiggle: The test tells you in plain words whether your microphone works, is too quiet, is distorting, or is sending no sound at all, and what to do about it.
Hear yourself back: Record a few seconds and play it back to judge the real sound quality, then download the clip if you want to share it.
Accurate levels: A level meter in decibels with a peak marker, a live waveform and a frequency view, measured from the raw microphone signal.
Every microphone on your device: Switch between built-in, headset and USB microphones and see each one's sample rate, channels and processing.
Private by design: The sound is analysed inside your browser and never uploaded. Press Stop test and the microphone is released immediately.
Frequently asked questions
How do I know if my microphone is working?
Start the test and speak. If the level bar moves into the green and the message says your microphone is working, it is. The recording lets you confirm the sound quality by ear.
Why does it say no sound is reaching the microphone?
The browser can use the microphone, but it is picking up almost nothing. It may be muted with a switch on a headset or cable, set to a very low input level, or the wrong microphone may be selected. Try the list of microphones on the page.
What does pure silence mean?
A working microphone always picks up a little background noise. A signal of exact zeros usually means the microphone is muted by the system, disabled in privacy settings, or held by another app.
What is a good microphone level?
For speech, the level should mostly sit between about -30 and -12 dB, in the green part of the meter. Hitting 0 dB means the sound is too loud and is distorting.
Is my voice recorded or uploaded?
No. The test runs in your browser. The short recording is only made when you press Record, stays on your device, and disappears when you leave the page.
The browser never asked for permission. What now?
Look for a microphone or lock icon in the address bar and set the microphone to Allow for this site. On a phone, also check that the browser app has microphone permission in the system settings.
What is call processing?
Echo cancellation, noise suppression and automatic gain, which apps like Zoom and Meet turn on. Leave it off to test the microphone itself, or turn it on to hear roughly what others hear in a call.
