How to Test Your Microphone
1
Click "Start Microphone Test"
Your browser will ask for microphone access. Click Allow. This only lets the page hear your mic — nothing is recorded or uploaded to any server.
2
Speak into your microphone
Talk at your normal volume. Watch the bar on screen move in response to your voice. If the bar moves when you speak, your microphone is working.
3
Check your results
After stopping, you'll see a mic quality score based on your volume, background noise, and stability. Download the recording to hear exactly how you sound to others.
Microphone Not Working?
Most microphone problems are quick to fix. Check these common causes:
Browser access was blocked

Wrong input device selected
Open your system sound settings and make sure the correct microphone is set as the default input device.
Another app is using your mic
Zoom, Teams, Discord, or another app may have exclusive control. Close them completely and try again.
Microphone is muted
Check for a mute button on the mic itself or on the cable, and check the input volume level in your system settings.
