Test your microphone in your browser with a live audio level visualizer. Check if your mic is working without any app.
If your mic isn't working: (1) Check browser permissions — click the mic icon in the address bar. (2) Check your OS audio settings and ensure the correct input device is selected. (3) On Windows: Settings > System > Sound > Input. On Mac: System Settings > Sound > Input. (4) Try a different browser to rule out browser-specific issues.
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.
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.
