This microphone test answers one question in about ten seconds: is your mic actually working, and how do you sound to other people? Press start, allow microphone access, and watch the bars react to your voice. Then record a five second clip and play it back, because the live meter proves the mic picks up sound, while the recording reveals the part you normally never hear: your actual voice quality on the other end of calls and voice notes.
Everything runs inside your browser. The audio is analyzed and played back on your own device, never uploaded, never stored.
How to Read Your Microphone Test Results
- Bars move clearly and the recording sounds like you: the microphone is healthy. If people still complain they cannot hear you on calls, the problem is usually the app’s own input settings or your grip covering the mic hole, not the hardware.
- Bars barely move: the mic is picking up very little. Check that nothing covers the microphone opening, remove thick cases, and make sure no other app is holding the mic. On computers, also check the input volume in system sound settings.
- Recording sounds muffled or distant: the microphone opening is likely blocked by dust, lint, or a case, or the mic got wet recently. Phone microphones sit in tiny holes that clog exactly like speaker grills do. iPhone users can isolate exactly which of the three mics is blocked with our iPhone muffled microphone guide.
- Recording crackles or cuts out: moisture is a common cause, and so is a damaged mic module after a drop. Crackling that appeared right after water exposure often clears as the phone dries fully.
- Nothing happens at all: the browser was denied permission, or the device has no working mic. The tool’s own messages walk you through fixing the permission.
Where Your Phone’s Microphones Actually Are
Modern phones carry two or three microphones, and knowing where they sit explains many “broken mic” mysteries. The main mic is a pinhole on the bottom edge, next to the charging port, and on most iPhones it shares the bottom edge with the speaker, one grill being the speaker and the other the mic. A second mic near the rear camera records video sound, and many phones add a third at the top for noise cancellation. A finger or case covering the wrong pinhole during calls produces the exact symptoms of a faulty microphone.
Testing the Rest of Your Audio
A microphone problem and a speaker problem feel similar from the outside, since both end in “I cannot hear / they cannot hear me.” This test isolates the mic. To check the output side, run our speaker sound test, which plays each channel separately. And if your microphone got muffled after dust buildup or water contact, the same sound based cleaning that clears speakers helps mic openings too: run a cycle with our speaker cleaner and wipe the mic pinhole area with a soft dry brush. For phones that recently met water, start with the water eject tool first. Your phone’s haptics can be checked the same way with the vibration test.
FAQ
How do I test if my microphone is working?
Press start on the tool above, allow microphone access, and speak. Moving bars confirm the mic picks up sound, and the five second recording lets you hear your actual voice quality. The whole check takes about ten seconds.
Is this microphone test private?
Yes. The audio is processed entirely in your browser. Nothing is uploaded, stored, or shared, and the recording disappears when you leave the page.
Why do the bars move but I sound muffled in the recording?
The mic works but its opening is partially blocked. Dust, pocket lint, cases, and dried water residue in the microphone pinhole are the usual causes. Clean gently with a soft dry brush and never insert anything into the hole.
Why did the test ask for permission and then fail?
Browsers block microphone access once you deny it. Tap the lock icon in the address bar, set the microphone to Allow, and press start again. On iPhones, also check Settings, Safari, Microphone.
Does this test work for headset and Bluetooth microphones?
Yes. The browser tests whichever microphone is active. Connect the headset first, then start the test; on computers you can pick the input device in system sound settings.
