Why test your mic in the browser?

When a microphone “doesn’t work” in Zoom, Discord or Teams, it is hard to tell whether the problem is the mic itself or the app’s settings. This page talks to your microphone directly through the browser, with no extra software in between.

If the level bar moves here, your microphone, cable and operating system are fine — the problem is inside the app. If nothing moves here either, work through the checklist below.

Microphone not working? Check these in order

  1. Mute switch: many headsets have a mute button on the cable or a flip-up boom that mutes the mic.
  2. Connection: unplug and re-plug. On a PC with separate jacks, the mic goes into the pink one. For USB mics, try a port directly on the computer, not a hub.
  3. The right device: if you have several mics (webcam, headset, laptop), pick the right one in the “Microphone” menu above after starting the test.
  4. Browser permission: click the lock or camera icon in the address bar and set Microphone to “Allow”, then reload.
  5. System permission: on Windows and macOS the operating system can block the browser from using the mic (see below).
  6. Input volume: if the bar barely moves, raise the input level in your system sound settings.

Windows 10 / 11

  • Settings → Privacy & security → Microphone: turn on “Microphone access” and “Let desktop apps access your microphone”.
  • Settings → System → Sound → Input: choose your microphone and speak — the bar under “Test your microphone” should move.
  • Still silent? Right-click the speaker icon → Sound settings → More sound settings → Recording, and check the mic is not disabled.

macOS

  • System Settings → Privacy & Security → Microphone: allow your browser (Chrome, Safari, Edge…). Restart the browser afterwards.
  • System Settings → Sound → Input: select the microphone and check the input level meter.

Works here but not in Zoom, Discord or Teams?

Then the microphone is fine and the app is using a different device or has its own mute. In Zoom: Settings → Audio → Microphone. In Discord: User Settings → Voice & Video → Input Device, and try turning off “Automatically determine input sensitivity”. In Teams: Settings → Devices → Microphone. Close other apps that may be holding the mic, then restart the app.

Reading the level meter

The meter shows the input level in dBFS (decibels relative to full scale). 0 dBFS is the loudest possible signal. Normal speech at arm’s length usually peaks between −30 and −10 dBFS. If your voice stays below about −45 dBFS, you will sound quiet to others; if it constantly hits 0 dBFS, it may distort.

We turn off echo cancellation, noise suppression and automatic gain for this test so you hear what the microphone really captures.

Your privacy

Audio is processed only in your browser’s memory. The 5-second recording is never uploaded and disappears when you close the page.

Frequently asked questions

Is this microphone test free?

Yes. It’s free, needs no sign-up and installs nothing.

Do you record or upload my voice?

No. Everything stays in your browser. The optional recording is kept in memory only so you can play it back, and it’s deleted when you leave the page.

Why does the browser ask for permission?

Browsers never let websites use your microphone without asking. You can revoke the permission at any time from the lock icon in the address bar.

The bar moves but my voice sounds bad in the recording. Why?

Common causes are a mic that is too far away, a noisy room, or input volume set so high that it clips. Move closer, lower the input volume slightly, and try again.

Does it work with USB, Bluetooth and headset mics?

Yes — any microphone your operating system recognises will appear in the device list after you start the test.
