plot microphone magnitude using SigmaStudio

How can I plot the input magnitude of a microphone that is connected to an ADAU1761 eval board? The stimulus and probe do not seem to be plotting the throughput data, just filtering/parametric type changes to the data? The graph option just possibly is plotting the oversampling digital values? I am new to audio and SigmaStudio so any help is appreciated.

I added the project that has two parts and interest in the first part for magnitude at the first graph.

Thanks.
