How to use the mic test

1Click “Test My Microphone”
Your browser will ask for microphone permission. Choose Allow — the test cannot hear anything without it.
2Speak and watch the meter
Talk at your normal volume. The level bar and waveform should jump with your voice, and your exact mic model appears above.
3Record a 5-second sample
Hit record, say a sentence, then play it back to hear exactly how you will sound on your call or stream.
4Fix it if something is off

Why this mic test works well

Live volume meter with peak hold

A real-time level bar with a peak marker shows exactly how loud your mic is — aim for the green “good level” zone, not the red.

Real waveform display

An oscilloscope-style waveform draws your actual voice signal, so you can spot cutouts, distortion, or a dead mic instantly.

Shows your exact device name

See precisely which microphone is active — handy when a laptop, headset, and webcam mic are all fighting for control.

Switch microphones instantly

After permission is granted, pick any connected mic from the dropdown and test each one without reloading.

Record-and-play-back sample

A 5-second recording proves the whole chain works — capture, encoding, and playback — and you can download the sample.

Clear fix-it guidance

Blocked permissions and missing-mic errors come with step-by-step instructions for Chrome, Firefox, Safari, Windows, and Mac.

Mic test FAQs

Is this mic test really free?

Yes — completely free, with no signup, no trial, and no limits on how many times you test. It runs entirely in your browser.

Is my voice recorded or uploaded anywhere?

No. The volume meter and waveform are computed locally in your browser in real time. Audio is only captured into memory if you press the record button, and that sample never leaves your device — you can download or discard it.

Why does it say permission was denied?

You (or your browser settings) blocked microphone access. Click the tune/lock icon left of the address bar, set Microphone to Allow, and reload. On Windows and Mac, also check the operating system’s privacy settings — the OS can block the browser itself.

The meter barely moves. How do I fix low mic volume?

First, move closer to the mic and speak up. Then check your input volume: Windows → Settings → System → Sound → Input volume; Mac → System Settings → Sound → Input volume. Also make sure no physical mute switch on your headset is engaged.

Can I test a specific microphone?

Yes. After you grant permission once, the dropdown above the meter lists every connected mic — your headset, webcam mic, USB mic, and so on. Select one and the test switches to it immediately.

Does it work on phones and tablets?

Yes. It works in Chrome and Safari on iOS and Android. Grant the permission when asked; on some phones you may need to pick the right mic if a headset is plugged in.

Which browsers are supported?

Any modern browser with WebRTC microphone support: Chrome, Edge, Firefox, Safari, Opera, and Brave on desktop and mobile. Very old browsers without getUserMedia are not supported.

The meter is pinned in the red. What should I do?

Your input gain is too high — your voice will sound distorted. Turn the input volume down in your OS sound settings, move slightly farther from the mic, and re-test until peaks land in the green zone.
