I would guess that the “compensate for bounces off buildings” part is the Achilles heel of this technology. When I worked in telecom we had similar problems with reflections in phone lines, which is a highly controlled environment compared to anything that could potentially reflect sound in a city. And even then we weren’t trying to locate something in 3-dimensional space with reflections, just decode information in spite of them. The more I think about it the more this technology sounds like vaporware except in really ideal conditions, like an open field in the middle of farmland or something.
