Understanding Quality Metrics

Volume Level

Indicates how loud your microphone input is. 'Low' means speak louder or move closer to the mic. 'Good' means optimal volume level.

Audio Quality

Overall assessment of your audio clarity. 'Good' means clear audio with minimal distortion. 'Poor' suggests checking mic settings or hardware.

Noise Level

Measures background noise and interference. 'Low' is ideal. 'High' means there's significant background noise affecting quality.

Common Microphone Issues

No sound detected: Check if microphone is plugged in and selected as input device in system settings
Low volume: Increase microphone gain in system settings or speak closer to the mic
High noise: Move to quieter environment or use noise-cancelling microphone
Distorted audio: Reduce microphone gain or move farther from the mic to avoid clipping
Permission denied: Check browser settings to ensure microphone access is allowed
