The nRF5340 is a TX board. I processed PDM data in it. How can I process PDM data to an audio file that I can send to the nRF5340 audio DK board?

Hello,
I am not sure what you are asking.
Are you asking how to convert data into a file? I don't know if we have any sample of doing that, but there are some filing samples: filing
Hi Naeem,
I require more than one second of PCM data. Also, how should I go about playing it?
Thanks & Regards,
PSR.
Hi PSR,
In the nRF5340 Audio applications, the PDM data is routed through the HW codec (CS47L63) and the relevant source file to study our implementation is in audio_datapath.c.
See the application overview here: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/applications/nrf5340_audio/doc/firmware_architecture.html.
Best regards,
Maria
