What do the decibel (dB) levels mean?

Decibel levels measure sound intensity. Normal speech is around 60-70 dB. Levels below -30 dB may indicate a weak signal, while levels above -3 dB may cause clipping/distortion.

Can I save my microphone test recordings?

Yes, after recording a sample, you can download it as a WAV file using the download button that appears in the results section.
