[LINK] Government teleconferencing

[Richard Chirgwin]

Thinking randomish ...

We are, I suspect, more susceptible to good psycho-acoustics; by which I
mean, I suppose, that "phone plus video" just doesn't "kick" as well as
the telepresence.

Funny, you could go a long way with a stereo microphone and some
smart-enough software ... not that you would get "telepresence" but you
could certainly get good placement of the apparent location of a voice
to someone at the other end, esp wearing headphones.

(All of this has been known to record producers for years. You can track
the progress of certain tricks, from where they were first noticed to
when they became passe).

Cheers,
RC
