that might depend. I used already a usb mic array and a i2s mic array and do not really have any more lagg

Excellent. It has been my experience that a USB mic introduces lag, even on a quad core i7 machine. I’ve never used that array you speak of but if you’re having no lag using it on a Pi then more power to you brother.
