ADAU1772 sound level measurement

Hi,

we're thinking about using the ADAU1772 for our application.

We'd like to achieve a "volume level compensation" detecting the level of noise through the microphone, and adjusting the volume accordingly.

Unfortunately we don't have a microphone dedicated to listed only to the noise.

Is it possible to have a measurement of the level of the power coming from one of the input ADC?

Thanks and regards,

Alessandro
