The PmodMIC is designed to digitally report to the host board whenever it detects any external noise. By sending a 12-bit digital value representative of frequency and volume of the noise, this number can be processed by the system board and have the received sound accurately reproduced through a speaker. | The PmodMIC is designed to digitally report to the host board whenever it detects any external noise.

- | The dynamic range compressor on the microphone module helps restrict incoming audio decibels by making the softer sounds louder and the louder sounds softer. The SA575 has its compressor rated for a unity gain level of 0.5 decibels meaning that incoming audio signals will have their decibel level decreased by half, bringing a signal with at -40dB to -20dB. | + | The dynamic range compressor on the microphone module helps restrict incoming audio decibels by making the softer sounds louder and the louder sounds softer.
