Hi, team, does maestro framework support recording audio to mp3/opus file, my understanding is it only support recording to pcm/wav file, am I right? thanks in advance.

Hi Ji Chen, Theoretically it is possible, there is opus encoder supported in Maestro. However it is not fully tested. There is a pipeline using memory source -> opus encoder -> memory sink in the maestro_record demo in the MCUXPresso SDK. Please see the examples for example here: https://github.com/nxp-mcuxpresso/mcux-sdk-examples/tree/MCUX_2.16.000/evkcmimxrt1060/audio_examples Best regards Tomas
