We have a potential application retro-fitting a retail kiosk intercom with better noise rejection.
(A custom ReSpeaker Mic Array (v1/v2) with linear mic array and analog echo suppression input may be a final solution)
Being able to connect a USB audio interface dongle (for which PCs have built in drivers) would be a quick prototype testing solution) could the ReSpeaker Mic Array v2) be coded to recognize these adapters?
USB 7.1 ch audio adapter (most models have no controls)
This may be a simple way to widen the possible applications for the board.
