How to Test Your Microphone Online (Free, No Download)

Quick answer: To test your microphone online, open a browser mic test, click start, and allow microphone access when your browser asks. Speak normally — if the waveform or level meter moves, your mic is working. Nothing is recorded; the whole test runs on your device.

Try it now: open the microphone test , click start, and say a few words. The steps below cover the permission prompt and what to do if nothing moves.

How to test your microphone in three steps

1. Open the test and click start

Go to the microphone test and press the start button. No download or sign-up is needed — it runs in the browser.

2. Allow microphone access

Your browser shows a permission pop-up, usually near the address bar (on a phone, scroll to the top to see it). Choose Allow. The test cannot read your mic until you grant access.

3. Speak and watch the meter

Say "hello" at a normal volume. If the waveform or level bar moves in time with your voice, your microphone works and is set as the active input.

Why does my browser keep asking for microphone permission?

Browsers ask each new site for permission to protect your privacy. To stop the prompt on a site you trust, click the lock icon in the address bar, open site settings, and set Microphone to Allow.

Can I test a headset, USB or Bluetooth microphone?

Yes. Connect the headset or external mic first, then select it as the input — either in the test's device selector or in your computer's sound settings — so the test listens to the right device rather than the built-in mic.

The mic test is not picking up any sound

If the meter stays flat, work through these in order: confirm you clicked Allow; check the correct input device is selected (not a disconnected or built-in mic); make sure the mic is not muted or its volume is at zero; and close other apps that may be using it, since a mic in use elsewhere can block the test. For wired mics, reseat the plug.

My mic passed the test but does not work in a call

If the test sees your mic but Zoom, Teams or Discord does not, the hardware is fine — the app simply has the wrong input selected or is muted. Open that app's audio settings and choose your microphone. Our guide on fixing a mic that no one can hear on Zoom walks through it.

Is the microphone test private?

Yes. A browser-based test processes audio only on your device — nothing is uploaded, recorded, or sent to a server. Any playback you record stays with you.

Confirm your mic works

Once the meter responds to your voice on the microphone test , your mic is working. If it passes here but fails in one specific app, the fix is in that app's settings, not your hardware.
