Common microphone problems and solutions

Check browser mic permissions by clicking the address bar icon. Verify your OS selects the correct input device in sound settings. On Windows go to Settings > System > Sound > Input. On Mac go to System Settings > Sound > Input. Ensure no other app has exclusive microphone control.

Understanding audio levels

Good speaking levels peak at -12 to -6 dB, loud enough to be clear with headroom to avoid clipping. Background noise shows as constant low-level activity in the visualizer. If levels are too low, increase microphone gain in OS sound settings.

Why is my microphone not working? +
Check browser permissions, OS audio input settings, physical connections, and whether another app has exclusive microphone access.
How do I allow mic access in Chrome? +
Click the mic icon in the address bar and select Allow. Or Settings > Privacy > Site settings > Microphone.
What sample rate should my mic use? +
44.1kHz or 48kHz are standard. 48kHz is preferred for calls. 96kHz benefits music recording. Most USB mics auto-select the appropriate rate.
Can websites record my mic without permission? +
No. Browsers require explicit consent and the mic icon appears in the address bar whenever any site accesses your microphone.
