How to read audio data in SAI example SDK for i.MXRT1050-EVKB

Hi all,


I am trying to read the audio data from the sai_edma_record_playback example where the program records and plays back audio data from the on-board MIC and process 16 bit samples of the data at 8khz (30 millisecond audio frames).


I have looked at the buffer however it doesn't seem to contain the correct data.


Could anyone help me with this? (attached is the code, sourced from the SDK)


Many thanks
