Actually I can't let it rest at that. You pointed to a stanford website about audio technologies. That's not a solution, that's an idea that exists in fairy tale land. The delta between that and my home theater room is so huge, you could fit planets inside. Good luck getting that standardized, implemented in hardware and software, implemented in the mixing studios, implemented with the content creators, the players, the full stack. It could be done, but it requires earnest organized effort that open source flat-out fails on.
Open-source proponents are often fanatical and oblivious to the real world - drumming up achievements like they are the God that brought light to the earth, while ignoring shortcomings, or the achievements of industry. Open source solutions didn't bring us CDs, that took huge efforts on the parts of Philips and Sony. It didn't bring us the mass-scale silicon manufacturing for all the chips we have, didn't design the chips. Didn't bring cars. Cargo ships. Airplanes. Roads. Often the open source development hopes to and is proud to achieve what industry already achieved in decades past.
Then there's actually using open-source solutions, which remain for the most part utter garbage. Linux is terrible and always has been terrible. Try to get your mother to use Linux as a desktop OS lol. Python is hot garbage when you need to actually get stuff done. Matlab wins. Microsoft office is way better than Libreoffice or whatever abomination linux users are forced to use. Photoshop reigns supreme for a reason (despite adobe's terrible subscription model). I was looking for a replacement to my WDTV media player. Unfortunately the best solution is Kodi. Getting something like that set up requires days of misery and delving into the deep recesses of the 2nd and 3rd pages of google searhc, along with sacrificing a few chickens that you find what you want/need.
I'm sorry to be so forceful, but to merely shouting "BUT OPEN SOURCE" only distracts from the issue and gets in the way.
