[jichen0919_nxp]

Greetings ,

I have one question regarding maestro audio framework,  there is one example that record audio from microphone and save it to pcm file, my question is does maestro framework support recording audio and save it to opus audio file,

can I implemented using a custom pipeline, including following 3 element,

TYPE_ELEMENT_AUDIO_SRC,TYPE_ELEMENT_ENCODER,ELEMENT_FILE_SINK_INDEX

thanks in advance.

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
