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
