MICROPHONE TEST GUIDE
Understand your results
Audio levels
-60 to -20 dB is ambient noise, -20 to -12 dB normal speech, -12 to -6 dB ideal recording, and -6 to 0 dB risks clipping.
Background noise
Keep the microphone 15–30 cm from your mouth. Turn off fans and air conditioning and reduce room reflections.
Microphone types
Dynamic microphones reject noise well. Condensers are more sensitive. USB is convenient, while XLR offers professional connectivity.
Troubleshooting
If no sound is detected, check browser permission, the hardware mute switch and your operating system's input level.
PRIVACY FIRST
