hi, I have a stm32l476 necleo-64 board and CCA02M1 extension board. I want to modify the the Microphones_Streaming example. and I want to use it to record 4 channel microphone and with 48000Hz sample rate. and I just change the macro definition AUDIO_CHANNELS in the aduio_application.h. change the 2 to 4
and I think mabe I should change the USB descripter at the same time, but how to modify it ?
