How can I process PDM data to an audio file that I can send to the nRF5340 audio DK board?en-USTelligent Community 13Fri, 19 Jul 2024 13:55:28 GMThttps://devzone.nordicsemi.com/thread/494837?ContentTypeID=1Fri, 19 Jul 2024 13:55:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:eefa400b-72c0-46a2-9abc-332067a3d640Maria Gilje<p>Hi PSR,</p> <p>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 <a href="https://github.com/nrfconnect/sdk-nrf/blob/v2.7.0/applications/nrf5340_audio/src/audio/audio_datapath.c">audio_datapath.c</a>.</p> <p>See the application overview here: <a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/applications/nrf5340_audio/doc/firmware_architecture.html">https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/applications/nrf5340_audio/doc/firmware_architecture.html</a>.</p> <p>Best regards,</p> <p>Maria</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/494095?ContentTypeID=1Tue, 16 Jul 2024 10:24:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1bf15ca8-6697-4c0d-b1c9-7e8ad6a7d1c9PSR<p>Hi Naeem,</p> <p>I require more than one second of PCM data.

I don&#39;t know if we have any sample of doing that, but there are some filing samples:&nbsp;<a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/zephyr/services/file_system/index.html">filing</a></p><div style="clear:both;"></div>
