If this actually works, I am desperately keen to get my hands on it. If you have the capacity for high bandwidth, why not use it? Zoom’s model must work on whatever crappy broadband people have in their home office. If you have gigabit, it doesn’t seem to make use of that extra capacity to improve video quality.

As for sound, I don’t think audiophile quality is necessary...

Given you'll need about 10Mbps upstream for 60fps 3K video it seems a little unreasonable not to add on a 320Kpbs (or more) audio stream.

It could make this useful for things like streaming music concerts.

Semi-related note: there's work being done at Stanford to make it possible for remote musicians to play together in an ensemble at low latencies.

JackTrip is the resulting software -- not end-user friendly, but apparently it works.

(Some basic numbers: sounds takes 1 ms to travel a foot, every ms is a foot of separation between musicians, 30ms of latency = 30 ft separation = the max for jamming. So 130ms is not low enough.)

Also, audio quality seems to be more important for the subjective experience than video quality, even in regular video content.
If you only need a P2P video stream https://github.com/CESNET/UltraGrid/wiki is amazing and lower latency
Let's turn that statement around and instead of thinking about audio bitrates, focus on experience. A great "audiophile" setup can make the performers sound there in the room with you. No matter how much BS the hobby spews, when you hear a really great setup, that guitar truly sounds 6 feet away from you.

Zoom calls do not sound there in the room with you. Microphones are terrible, there's compression artifacts, latency, packet loss, background noise, and tiny speakers. No one could possibly close their eyes and forget that the other person is not there in the room with them, on any POTS or VOIP technology that exists. But what if you could create an audio communications system with an actual illusion of auditory presence. Sounds amazing!

And given that this company is trying to create wall-screen, life size ultra-HD video conferences, I'm pretty sure that "audiophile" exactly what they're going for. Personally as a remote worker, I would absolutely swoon for this.
