Test your microphone online: see the live input level, check which device is in use, and record a short sample to hear yourself. Private.
The mic test shows whether your microphone is working before a call, a stream, or a recording. Allow access and speak: a live meter and waveform show the input level, and the page confirms when sound is coming through or tells you when the mic is connected but silent. It also lists the device in use, its sample rate and channel count, and which browser processing is on, and lets you switch between microphones if you have more than one.
Record a five-second sample to hear how you sound to other people — the quickest way to catch a muffled, distant, or distorted mic. The check runs on your device: nothing is uploaded, the sample is discarded when you leave, and the microphone is released when you stop. If there is no sound, look at the hardware mute switch, the system input level, and the selected device. When it works, the audio recorder makes a full recording, and how to record audio in your browser covers setup.
Press Test my microphone, allow access when the browser asks, and speak normally. The level meter and waveform should move, and the page confirms when it detects sound. To check quality as well as level, record the five-second sample and play it back.
The usual causes are a hardware mute switch on the headset or laptop, the wrong input selected, the input level set to zero in the system sound settings, or permission blocked for the site. If the page says the mic is connected but silent, switch devices in the list and check the system input level. If permission was blocked, re-allow it from the padlock icon in the address bar.
Yes. The level is measured on your device, and the optional five-second sample is held in the browser tab's memory only so you can play it back. Nothing is uploaded or saved, the sample is discarded when you record another or leave the page, and the microphone is released when you stop the test.
It lists the voice processing your browser has switched on for the microphone: echo cancellation, noise suppression, and auto gain, or none. The test opens the mic with the browser's default settings, which in most browsers enable all three, as browser-based calls usually do. Noise suppression can pull the meter down between words, and auto gain can lift a quiet mic. The five-second sample is recorded with the same processing, so it is a fair preview of how you sound on a browser call.
The number is the average level of your microphone signal in decibels relative to full scale, where 0 dB is the loudest a digital signal can go. The bar runs from -60 dB on the left to 0 dB on the right, with a thin marker that briefly holds recent highs, and the page reports sound as detected once the level rises above -42 dB. If normal speech pushes the bar close to the right end, lower the input level in your system settings to avoid distortion.
