Microphone test: check your mic online in the browser
This microphone test shows a live waveform that moves as you speak, so you can confirm your mic is picking up sound before a call, recording or stream. Grant permission, watch the line react to your voice, and use the level meter to check you're loud enough without clipping. You can even record a short clip and play it back to hear exactly how you sound. Everything runs in the browser. Nothing you say is recorded to a server or uploaded.
How to test your microphone
Start the test and allow microphone access, then speak normally. The waveform should move in time with your voice and the level meter should rise into the healthy green range. If you speak loudly and the meter barely moves, the input gain is low or the wrong microphone is selected; if it constantly slams to the top and distorts, turn the input level down. Record a few seconds and play it back to judge the actual sound quality and check for background noise.
Why isn't my microphone working?
A flat waveform usually means the browser is listening to a different input than you expect - pick the right device, or check your system sound settings. Make sure you allowed microphone access; if you blocked it, re-enable it from the microphone icon in the address bar. A hardware mute switch, a muted input in the OS, or another app holding the mic can also silence it.
Recording and privacy
When you record a clip it's captured and played back entirely within your browser using local memory: it's never sent anywhere, and it's discarded when you leave the page or record again. The waveform and level meter likewise process audio only on your device. This makes the test safe to use anywhere you need to confirm a microphone works.
Getting better sound
Position the mic close to your mouth but slightly off-axis to reduce popping, keep it away from fans and keyboards, and set the input level so normal speech sits in the middle of the meter with headroom to spare. For headsets and USB mics, make sure the correct device is selected as your system's default input.
Frequently asked questions
No. The waveform, level meter and any clip you record are all processed in your browser using local memory, and nothing is sent to a server. A recorded clip is discarded when you record again or leave the page.
Most often the browser is using a different input than you think. Select the correct microphone and check your system's default input. Also confirm you allowed mic access, that no hardware mute switch is on, and that another app isn't holding the microphone.
Speak at your normal volume and watch the level meter. It should rise into the healthy middle range with a little headroom at the top. If it barely moves, raise the input gain; if it constantly hits the maximum and distorts, lower it.
Click the microphone icon in your browser's address bar and set this site to Allow, then reload and start the test again. On mobile, check the site permissions in your browser settings. The test can't hear your mic until the browser grants access.
Yes. Record a short clip and play it back to hear exactly how you sound, including any background noise or echo. The recording stays in your browser and is never uploaded, so it's a private way to check your audio quality.
