Hi Martin,
I'd already read those and watched the video, but whilst they are good at overall descriptions
of the system and work flows, like I said,they really don't give any hard technical details at all.
In particular, there's nothing indicating how panning is handled either for the beds or the for the
final render of the sound objects in the cinema, which is what I (and, I suspect, many on this list)
am really interested in. There's also things like the video shows various physical mixers and a
joystick panner, but no info about how this translates into actual panning laws - also, iirc, the
joystick didn't seem to have height info, though I suppose one of the buttons on it could swap it
from horizontal only mode to hemispherical surface mode (a time honoured device in Ambisonics,
amongst other systems)

I work for Dolby Laboratories, although not in the Cinema group. I record
classical music (mostly choral and chamber) as my passion, and have recently
expanded my mic selection to include a Soundfield SPS200 in addition to my
Schoeps DoubleMS rig for 4.0 surround - which explains why I am here. :-)

Ok, had a bit of time to read the (somewhat limited) technical document and it
appears that it is
basically component audio + background soundscapes (aka "beds"), with final
render done in the
theatre by panning the individual audio objects according to the sound
trajectories defined in the
mixing stage. The beds are channel based, i.e. (I guess) pretty well standard
panned to speakers
5.1/7.1/9.1.... arrays. There's no info about how panning is done in cinema
renderer but maybe VBAP?
Anyone have any more detailed technical info?
Dave
