MIC_IN_ADC_CHANNELAppConfig.hSets the ADC channel used by the demo for the input audio samples from an attached microphone.
USE_TEST_TONEAppConfig.hWhen defined, this alters the demo to produce a square wave test tone when the first board button is pressed - * instead of sampling the board microphone.
MICROPHONE_BIASED_TO_HALF_RAILAppConfig.hWhen defined, this alters the demo so that the half VCC bias of the microphone input is subtracted.
