|
|
##################################################
|
|
|
|
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
