Hello,

We designed 9 digital microphone array boards, the reference development board is xCORE ARRAY MICROPHONE (7 microphones), the reference project is app_usb_aud_mic_array,

1, how to modify can be achieved by USB to 8 microphones collected PCM data(for example, using ALSA's arecord in Linux PC)?

2, how to modify can be achieved by USB to 9 microphones collected PCM data?

Attachment is design change.

Best Regards,
