What is a mic test?
A mic test is a quick check that confirms your microphone is picking up sound. On this page, you click Start mic test, allow microphone access, and speak. If the level bars move while you talk, your microphone works. Nothing is recorded or uploaded unless you choose to record a clip, and even then it stays on your device.
How the test works
-
Click Start mic test
No signup, no download, no install. The test runs right here on this page.
-
Click Allow
Your browser shows a small popup near the address bar asking to use your microphone. Click Allow. You can revoke it any time.
-
Speak normally
Say a few words at the volume you'd use on a call. The bars should move as you talk and land in the Good zone.
That's the whole test. If the bars moved, you're set for your call. Bookmark this page so it's one click away next time.
The full guide to checking your microphone online
Most people land on a mic test for one reason: a call is about to start and they need to know, right now, that they will be heard. An online mic check answers that in seconds. Your browser already has everything it needs to read your microphone, so there is no app to install and no account to create. You click start, your browser asks permission once, and a live level meter shows whether sound is reaching the page. If the bars jump when you talk, your mic works. If they stay flat, something is in the way, and the fixes below walk through it.
How does an online mic test actually work?
When you allow access, the page taps into the same audio stream your video apps use. It measures how loud the incoming signal is, many times per second, and draws that as moving bars. It does not understand your words or store them. It is only watching the volume. That is why a mic check online is safe to run: the audio never leaves your device, and the moment you close the tab, the connection ends. The privacy line near the top of this page is not marketing. It describes exactly what is and is not happening.
Mic not working? Start here.
If the bars do not move, the most common cause is permission. When the browser asked to use your microphone, a quick Block click leaves it shut off. Open the small lock or settings icon at the left of the address bar, find Microphone, set it to Allow, and reload. The second most common cause is the wrong input device. Laptops often list several microphones, and the browser may be listening to one that is unplugged or covered. Open your system sound settings, watch the input meter there, and pick whichever device responds when you talk. A surprising number of "broken" mics are simply muted: headset cables, earcups, and many desk mics have a physical mute switch, and a small red light usually means it is on.
Why does my mic work here but not in Zoom, Teams, or Discord?
Each app keeps its own microphone setting, separate from your computer and separate from this page. A mic that passes the test here can still be set wrong inside Zoom, Teams, Google Meet, or Discord. In Zoom, open Settings then Audio and choose the same mic that worked here. In Teams, it is under Settings then Devices. In Discord, it is Voice and Video. If the app still hears nothing, check that the app itself has microphone permission in your operating system's privacy settings, because a blocked app stays silent no matter which device you pick.
Headphones, AirPods, and headsets
Wireless earbuds are a frequent source of confusion. AirPods and similar earbuds switch to a lower quality "call mode" when an app uses their microphone, which is why you can sound thin or underwater on a meeting even though music sounds fine. They also love to stay paired to your phone, so the computer never gets the mic at all. Connect them to this device first, confirm they are selected as the input, then run the test. If you need to sound your best, a wired headset avoids the call-mode drop entirely and is hard to beat for clear, close speech.
What makes a microphone sound good?
Working and sounding good are two different things. The biggest factor is distance: the closer the mic is to your mouth, the fuller and clearer you sound, because it picks up less of the room. That is why a cheap mic on a boom arm often beats an expensive mic across the desk. The next factor is room noise. Fans, keyboards, and echoey rooms all bleed into your audio, and software noise removal can only do so much. Aim for the Good zone on the meter, not the loudest possible reading, since a signal that is too hot clips and distorts. A mic test with playback, where you record a short clip and listen back, is the fastest way to hear what others actually hear and catch problems your meter cannot show.
Reading your input level
The meter sorts your level into three zones. Aim for Good.
| Zone | What it means | What to do |
|---|---|---|
| Too quiet | Bars barely move when you talk. | Move closer or raise your input level in sound settings. |
| Good | Bars rise into the middle as you speak. | You're coming through clearly. Nothing to change. |
| Too loud | Bars slam to the top and stay there. | Back off the mic or lower input to avoid distortion. |
Mic not working? Quick fixes
Bars not moving? One of these solves it almost every time. Start at the top and work down.
1. Check the browser permission
Click the lock or settings icon at the left end of the address bar. Find Microphone, set it to Allow, then reload this page. If you clicked Block earlier, this is the fix.
2. Pick the right microphone
Computers often have several inputs. Open your system sound settings, look at the input device list, and speak while watching the level there. If a different mic responds, select it and run the test again.
3. Look for a mute switch
Most headsets have a mute button on the cable or earcup, and many desk mics mute when you tap the top. A red light usually means muted. Unmute and try again.
4. Check your Bluetooth connection
Wireless earbuds love to stay paired to your phone. Open Bluetooth settings on this computer and confirm your headphones are connected here, not to another device.
5. Close other apps using the mic
Zoom, Teams, and recording apps can hold on to your microphone so nothing else can use it. Quit them fully, then reload this page and start the test again.
6. Restart the browser
If nothing above worked, quit the browser completely and reopen it. A full restart clears stuck audio drivers more often than you'd expect.
Questions people ask
Does this page record my voice?
No. The level test only measures volume in real time and throws the audio away instantly. If you use the record button, the clip lives only in your browser so you can hear yourself, and it's deleted the moment you leave the page. Nothing is ever uploaded.
The test works here, so why isn't my mic working in Zoom?
Zoom picks its own microphone, separate from the rest of your computer. In Zoom, open Settings, then Audio, and choose the same mic that worked here. Also check that Zoom has microphone permission in your system privacy settings.
Why do I sound quiet or muffled?
Usually distance. Built-in laptop mics pick up the whole room, so move closer and speak toward the keyboard. You can also raise your input volume in system sound settings. If you sound underwater on Bluetooth earbuds, the earbuds switched to call mode, which always sounds worse. A wired headset fixes that.
Can I test AirPods or a headset here?
Yes. Connect them first, then start the test. If the bars don't move, your browser is probably still listening to the built-in mic. Switch the input in your system sound settings, then reload.
