Unfortunately they only hint at the envisioned application in the video and don't provide any further links, but the idea is amazing: Use sounds to monitor bio-diversity. Imagine we'd not need cameras and lots of luck to "catch" proof of an animals existence but a grid of interconnected omnidirectional microphones. We'd get real time tracking of individual animals in 3D and could have smartphones literally point the way to yet uncatalogued or even undiscovered species.

Somewhat related, but there was a very good talk at MLConf 2017 about using sound to catch illegal logging in the Amazon. Similar premise: collect the sound, analyze the patterns, and classify.

I worked on this as part of a project with US Fish and Wildlife in 2015 for bats! We were monitoring local populations to track the spread of White Nose syndrome. It wasn't in 3D, but we linked the audio data / classifications with lat/long points and plotted population estimates on maps.
