Frequently Asked Questions

How do I use this microphone test tool?
To use the microphone test tool: 1) Click 'Start Test' to grant microphone access 2) Speak into your microphone to see the real-time audio level visualization 3) Monitor the volume levels - green indicates good levels, yellow indicates high levels, and red indicates potential clipping 4) Use this to adjust your microphone settings or position for optimal audio quality.
What do the different colors in the level meter mean?
The level meter uses a color-coded system: Green bars (below -12dB) indicate safe audio levels, Yellow bars (-12dB to -6dB) suggest the audio is getting loud, and Red bars (above -6dB) warn of potential audio clipping or distortion. For best results, aim to keep your audio levels primarily in the green range.
Why can't the tool access my microphone?
If the tool can't access your microphone, it might be due to: 1) Browser permissions not being granted - check your browser's site settings 2) Another application using the microphone exclusively 3) No microphone being detected - ensure your microphone is properly connected and selected as the default input device in your system settings.
How accurate is the decibel (dB) measurement?
The dB measurements shown are relative to digital full scale (dBFS), where 0 dBFS represents the maximum possible digital audio level. While these measurements are accurate for digital audio levels, they don't represent absolute sound pressure levels (SPL) that you'd get from a calibrated sound level meter.
