Which browsers support the online mic test?

The tool works in Chrome, Firefox, Edge, and Safari. Chrome and Edge tend to give the best results. Make sure your browser is up to date, since older versions may not support the audio APIs this tool uses.

Can I hear my own voice played back?

Yes. The tool records a few seconds of audio and lets you play it back through your speakers or headphones. This way you can check both your microphone quality and your speaker output in one go.

Does this test my speakers too?

Yes. When you play back the recorded audio, it plays through your current output device. If you can hear the playback clearly, your speakers or headphones are working fine.

Why is my microphone not being detected?

The most common causes are: your browser blocked mic access (check the address bar for a blocked icon), your mic isn't set as the default input device in your system settings, or another app is using the mic exclusively. Try closing other apps that might be using your mic and refresh the page.

Is my audio recorded or stored anywhere?

No. Everything happens locally in your browser. The audio never leaves your device and nothing is sent to any server. Once you close the page, the recording is gone.

Can I test multiple microphones at once?

You can test one mic at a time. If you have multiple microphones connected, select the one you want to test from the dropdown (if available) or change your default input device in your system settings before running the test.

What is an online mic test?

An online mic test is a browser-based tool that checks whether your microphone is working correctly. It accesses your mic through the browser, shows you real-time audio levels, and lets you record a short clip to hear how you sound. Some tools also test your speakers and headphones so you can verify both input and output before joining a call.

How to Test Your Microphone Online

Click "Start Test" — Hit the button above to begin. Your browser will ask for permission to access your microphone.
Allow mic access — Click "Allow" when the browser prompt appears. This is required for the test to work.
Speak into your mic — Say a few words and watch the audio level meter. If the bars move, your mic is picking up sound.
Listen to playback — The tool records a short clip automatically. Click play to hear how you sound through your current mic and speakers.
Check your levels — If the audio is too quiet or too loud, adjust your mic settings in your operating system and test again.

The whole test takes about 30 seconds. You can run it as many times as you need.

Why Test Your Mic Before a Meeting?

Avoid the "can you hear me?" moment. Nothing kills the energy of a meeting faster than spending the first five minutes troubleshooting audio. A quick mic test beforehand means you join ready to go.

Troubleshoot audio problems. If your mic isn't working, you want to know before the call starts. This tool helps you figure out whether the issue is your mic, your browser permissions, or your speaker output so you can fix it.

Verify new hardware. Just got a new headset or USB mic? Run a quick test to make sure your computer recognizes it and the audio quality is good before you rely on it for an important call.
