Mic Test — Test Your Microphone Online

Test your microphone online

This free mic test checks whether your microphone is working — right in your browser, with no download and no signup. Press Test my microphone, allow access when your browser asks, then speak. If the green-to-red volume bar moves and the waveform reacts to your voice, your microphone is working correctly.

How it works (3 steps)

1. Click Test my microphone.
2. Click Allow in the permission popup.
3. Speak — watch the volume bar and waveform respond.

Microphone not working? Troubleshooting

Quick checks

• Make sure the mic is plugged in and not muted (check any physical mute switch).
• If you denied permission, click the camera/mic icon in the address bar and allow it, then retry.
• Pick the right input device from the dropdown above.
• Close other apps (Zoom, Teams, Discord) that may be holding the microphone.

Windows

Settings → System → Sound → Input: pick the correct device and check the input level. Settings → Privacy & security → Microphone: make sure browser access is allowed.

macOS

System Settings → Privacy & Security → Microphone: enable your browser. System Settings → Sound → Input: select the right device.

App-specific (Discord / Zoom / Teams)

If the mic works here but not in a meeting app, the device choice inside that app is wrong. See our Discord, Zoom and Teams guides.
