Hi @jichen0919_nxp,

Thank you for contacting NXP Support.

This software is unsupported for i.MX microprocessors family.
If you are using a microcontroller, please submit your question in the correct section.

We have below demo in SDK, it can record from MIC and save .pcm file into SD card (shellRecMIC), it can also encode a hardcoded pcm data buffer to opus format (shellOpusEncode), so we can refer to this demo and merge these two shellTasks
