I don't think you need a new standard for that -- UWB radios, like Apple's already-deployed U1 chip, have the bandwidth to easily be bandying about 96/24 FLAC/A

I don't think you need a new standard for that -- UWB radios, like Apple's already-deployed U1 chip, have the bandwidth to easily be bandying about 96/24 FLAC/ALAC files, at the least. (Personally, I'd settle for topping out at 48/16 lossless ALAC.)
