Right, difficult to do the four mics when they're
in your fixed array box. Maybe being able to
slate some level consistently with each set-up
would help? Perhaps a low volume piezo buzzer
isolated from the lid itself but equidistant from
all four mics? If the distances from the mics or
the mics responses to the buzzer differed for
some reason, at least these relations would be
established to be better addressed it in post.
