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)

Dave,

Here are some links with additional information on both the system and the 
theater requirements.

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
