There was an article on this more some time ago in the
Acoustical Society of America's "Echoes" news letter.
Tapio Lokki is doing some interesting work.

How are they actually recording in the concert hall? They would have to use
binaural or Ambisonic recording in order to get an accurate rendition of the
hall sound.

This was the same information that was in the OP's link. When I clicked on
the further informaiton link I got a page not found.

My main question would be about the line "The symphony orchestra simulator
has been played in many famous European concert halls and that music has
been recorded in different locations within the halls and analysed" (back in
the laboratory).

No explanation of how they played it back. I would think they used a
binaural head for recording and played it back on headphones or loudspeaker
binaural, but it just doesn't say in these links.

Nothing new here. We already know that what we hear in any environment, live
or reproduced, is the image model of the total horizontal acoustical
situation. Different halls have different acoustics. But you can't just
"record" that and "play it back." Even in stereo, that will only represent
some aspects of what you would hear on site in the actual acoustics.

So they need some more 'splaining than this.

Oops. It was the first link I noticed in my browser
history file. Try poking about in these links:

There is, to the effect of "each musician recorded in a sound dead room and
played back via loudspeaker on musicians position". I just followed the
posted link.

Kind regards

Not talking about that Peter. It says they then recorded what you are
talking about and played THAT back in the laboratory. Later links seem to
confirm my theory that they did it with binaural.

Sadly this isn't very useful at all because the radiation pattern of the
loudspeakers is very very different than the radiation pattern of the
instruments.

This was done in the early 1970s by Eugene Cerwinsky, and later
by folks at NHK in Japan.
