Why test your mic online?

An online mic test is the fastest way to separate a microphone problem from an app problem. If your mic works on this page, the hardware, the cable and your system settings are fine, and whatever went wrong is inside the app you were using. If it doesn’t work here either, you know to look at the mic itself, the connection or your permissions.

Because it runs in the browser, the test works the same way on a Windows PC, a Mac, a Chromebook or a phone. It uses the same microphone access that web-based meeting tools rely on, so it’s a realistic check before any call you take in a browser tab.

How the online mic test works

  1. Start the test and allow access

    Press “Test my mic”. Browsers only share your microphone with a page after you say yes, and only for this site.

  2. Confirm the right microphone is in use

    Look at the device name in the “Your microphone” panel. Laptops with a webcam, a headset and a built-in mic often pick a different one than you expect.

  3. Speak and read the level

    Count to ten at your usual speaking volume. Aim for a level that sits in the green and a rating of “Good”.

  4. Try your other microphones

    If more than one mic is connected, use the Microphone menu to switch between them and compare levels without leaving the page.

What a browser can and can’t tell you

A browser test is good at the basics: whether a microphone is connected, whether the site is allowed to use it, how strong the signal is, and which processing features are switched on. Those cover the large majority of “nobody can hear me” problems.

It can’t measure studio qualities such as frequency response or self-noise in any exact way. Browsers also process the signal before a page ever sees it. Echo cancellation, noise suppression and auto gain control are usually on by default, which is ideal for calls but means the level you see has already been tidied up.

Reading sample rate and channels

Sample rate is how many times per second your audio is measured. Most devices report 44.1 or 48 kHz, and either one is more than enough for clear speech. Bluetooth headsets often drop to 16 kHz or lower while their microphone is in use, which is why voices sound thinner on them.

Channels tells you whether the browser opened the mic in mono or stereo. One channel is normal and expected for voice.

Questions and answers

Is this online mic test free?

Yes, completely. There are no limits, no trial and no account.

Which browsers does it work in?

Current versions of Chrome, Edge, Firefox, Safari, Brave and Samsung Internet all work. Browsers built into other apps, such as the ones that open links inside Instagram or Facebook, frequently block microphone access, so open the page in your regular browser instead.

My mic works here but not in my meeting app. Why?

That points to the app’s own settings. Open its audio settings and make sure the same microphone you saw here is selected, that you aren’t muted in the app, and that your operating system allows that app to use the microphone.

Why does the test show a different mic than the one I plugged in?

Browsers start with the system’s default input device. Pick your microphone from the Microphone menu in the tool, or change the default input in your system sound settings.

Does the test work on a phone?

Yes. It works in Safari on iPhone and iPad and in Chrome on Android. The steps are the same: tap the button, allow microphone access, and speak.
