Mic test: check your microphone

Press the button, allow the microphone, and say something. You'll see straight away whether your mic is picking you up, how loud it is, and which device the browser is using. Then record five seconds and play it back to hear yourself the way people on a call do. It all runs on this page: your audio isn't uploaded.

Your browser will ask to use the microphone. Everything runs on this page: nothing is uploaded or saved.

How to read your results

The sample rate and channel count tell you what the browser is receiving. 48 kHz mono is typical for headsets and laptop mics; USB microphones often report 44.1 or 48 kHz.

Microphone not working? Fixes that solve most cases

1. Allow the microphone in your browser

If you clicked Block by mistake, click the microphone or lock icon at the left of the address bar and set the microphone to Allow, then reload. In Chrome you can also check Settings → Privacy and security → Site settings → Microphone.

2. Allow the browser in your system settings

On a Mac, open System Settings → Privacy & Security → Microphone and switch on your browser. On Windows 11, open Settings → Privacy & security → Microphone and make sure microphone access and desktop app access are both on.

3. Pick the right input

Laptops, webcams, headsets and monitors can all show up as microphones. Use the “Switch microphone” list above to try each one. To change the default for every app, use System Settings → Sound → Input on a Mac, or Settings → System → Sound → Input on Windows.

4. Fix the level

Both places above have an input volume slider. If the meter barely moves, raise it; if the test says “clipping”, lower it. Some USB microphones and audio interfaces also have a physical gain knob.

5. Close other apps using the mic

Video-call apps can hold on to a microphone. Quit them, unplug and replug a USB mic, and run the test again.

If your mic works here but voice typing still doesn't, our guide to speech to text not working covers the dictation-specific fixes for iPhone, Android, Mac and Windows.

Frequently asked questions

How do I test my mic online?

Click “Test my mic” above, allow microphone access when your browser asks, and speak. If the meter moves and the result says your microphone is working, it is. Record five seconds and play it back to check the sound quality as well.

Is this mic test private?

Yes. The level meter and the recording both run in your browser tab. No audio is sent to us or saved anywhere, and the clip disappears when you close the page.

Why does the mic test say it can't hear anything?

The browser has a microphone but it's sending silence. The usual causes are a hardware mute switch, the wrong input picked in the list above, or the input volume turned right down in your system's sound settings.

What is a good microphone level?

For speech, aim for the meter to bounce between roughly -25 and -10 dB when you talk at your normal volume, without touching the top. Much lower and people will struggle to hear you; hitting the top means the sound is distorting.

Does this mic test work on iPhone and Android?

Yes, in Safari on iPhone and Chrome on Android. Your phone will ask for microphone permission the first time. Phones usually have several microphones, and the browser picks one for you.

Can I test a USB microphone or headset?

Yes. Plug it in, start the test, and pick it from the "Switch microphone" list if it isn't already selected. The device name shown under the meter tells you which mic you're hearing.

Talk instead of type, in any app.
