This post is me reciting rumors about what I've heard of how things worked and how things played out. I'm not sure that I'm a good source for an article and I can't really officially confirm anything, even if I know it to be correct.

Your best option is probably to email virtual interview questions to Tom Ammermann, the CEO of https://newaudiotechnology.com/ He's a great guy, Granny-nominated sound engineer, and has been working on 3D sound with all those technologies for a long time.
