Intel® S1000 Digital Microphone Sample Application
##################################################
Overview
********
This sample application uses a digital microphone driver to receive interleaved
audio samples from a microphone array.
This app configures the digital microphone driver, starts the driver,
receives a number of frames and then stops the driver. This process is
repeated a few times.
Requirements
************
This application uses an Intel® S1000 Customer Reference Board (CRB)
with a circular 8 microphone array
