Online mic test

When you speak, the waveform moves, the level meter rises, and the status changes to "Your microphone is working". If the line stays flat, the browser is not receiving sound from that device.

No. The test runs entirely in your browser. Audio is analysed locally and is never sent to a server. The optional 5-second clip stays in memory and disappears when you close the tab.

Common causes are a muted device, the wrong input selected in your system sound settings, a low input volume, or another app holding the mic. Check each in turn, then retest.

They are browser audio filters tuned for calls. Turn them off to hear your raw microphone signal, or on to hear how a video call will sound.

Speech peaking between about -18 dB and -6 dB is healthy. Below -40 dB is too quiet, and touching 0 dB means the signal is clipping and will sound distorted.

The 3:1 rule says that when you use several microphones at once, each microphone should be at least three times farther from the other microphones than it is from its own sound source. For example, if a mic is 1 foot from a singer, place the next mic at least 3 feet away. This keeps sound from leaking between mics and avoids phase cancellation, which makes audio sound thin or hollow. It applies to multi-mic recording and live sound, not to a single headset or laptop mic.

Open this page, press Start test and allow microphone access. Put headphones on, then turn on Hear myself. You will hear your voice live through your headphones while the waveform and dB meter move. You can also record 5 seconds and play it back to judge how you sound to other people.

Press Start test, choose Allow when the browser asks for microphone access, and speak at normal volume. If the waveform moves and the level meter rises, your PC is receiving sound from the microphone. If you have more than one input, pick the right one from the microphone list and test again.

Speak at your normal volume and read the live decibel meter. A healthy level peaks in the green zone, roughly between -18 dB and -6 dB. If the peaks stay near the bottom, move closer to the mic or raise the input volume. If the meter hits the top and clips, move back or lower the input gain.

First check that the mic is plugged in firmly or paired over Bluetooth, and that the browser has microphone permission for this site. On Windows, open Settings > System > Sound, find your mic under Input and make sure it is enabled and not muted. Also check Settings > Privacy & security > Microphone, and allow microphone access for apps and your browser. Then reload this page and run the test again. If it still does not appear, try another USB port or cable, restart the browser, and close apps that may be using the microphone.

In Windows 11 you can open Settings > System > Sound, pick your mic under Input and use Start test to see the input volume bar move. To actually hear yourself, use this page: press Start test, put headphones on and turn on Hear myself. Your voice plays back live with almost no delay, so you can check tone and background noise. Use headphones, because open speakers cause a loud feedback squeal.

Yes. Open this page in Safari, tap Start test and choose Allow. The waveform and decibel meter work the same way as on a computer. If no prompt appears, check Settings, Safari, Microphone.

Run this test first to confirm your microphone works in the browser, then pick the same microphone in Zoom audio settings and use Zoom built-in test. Toggle echo cancellation and noise suppression here to hear how Zoom-style filtering changes your voice.

Tick Hear myself (loopback) after you start the test. Use headphones, because speakers cause feedback.

A mic test shows live levels so you can check the device. A recorder keeps the audio. This page does both briefly with a 5 second clip, and the voice recorder tool saves full MP3 recordings.
