:relevant-api: i2s_interface
Process an audio stream to codec.
Overview
********
This sample demonstrates how to use an I2S driver in a simple processing of
an audio stream. It configures and starts from memory buffer or from DMIC to
record i2s data and send to codec with DMA.
Requirements
************
This sample has been tested on mimxrt595_evk/mimxrt595s/cm33
