This is pretty cool, and reminded me of the far-field microphone array in an Amazon Echo (which uses 7 spaced out microphones). Which also makes me wonder, taking something like this (which has way more than just 7 mics) and applying it to the problem of far field speech recognition, are there large gains to be had? Just thinking of what new applications become possible, when you have the ability to print hundreds or thousands of miniature mics on a single board that will fit in a small-ish device.
