This is mildly terrifying. A way of dealing with it he doesn't mention would be to fill the audio with a lot of spurious Doppler curves. Devious people could pick sets of curves which would locate the audio somewhere it was not recorded. I can think of uses for that.

The first thing I thought of when I watched this video is this episode of The Bloodhound Gang on 3-2-1 Contact where the gang gets kidnapped by thieves and thrown in the back of a box truck. They're able to track where they are in part by hearing airplanes overhead. They also use a hole in the back of the truck to make a camera obscura. I loved that show!
