It's too bad that the angle measurement is not used for anything but Cinema DSP. That would be the solution for accuracy, but it would cause virtually all of our systems to use multiple speakers to phantom image sounds, and maybe we wouldn't find that ideal. After all, that's what we're setting our patterns to avoid currently.
They really need to implement a format/speaker pattern auto-switch in this case. i.e. it automatically picks a preferred (by the user) layout depending on the incoming signal. Or indeed auto-swaps the setting depending on the input signal, that would be transparent to the user.
Regarding the few additional comments on "correctness of placement", currently if I set overhead for DTS:X the call out seems like it's almost 100% in the back surrounds and the (couple of pretty poor) demos I have appear to have almost no rear height effect and the sounds are mis-placed versus on-screen. Curiously the phantoming of the front heights to L+R is much less, maybe 10 to 20% "bleed". Maybe they have made a mistake (bug) with the current decoder and it should be doing the same with the rear surrounds, only 10-20% bleed not near 100%?
On the demos, I have 3 from DWEU, one with chat about DTS:X, one with horses, cars and a space battle and the call out. The only one that seems ot have any kind of half-decent effects (irrespective of speaker setting) is the start of the call-out. Are others seeing that too or do you have any more demos?
It could be due to my front heights being far too close to the mains which I hope to fix this weekend and will see what that does.
It's not all bad with DTS though, the Neural:X is amazing on TV, I was watching last week's MotoGP with a stereo feed and DSU and it was "natural" like an expanded stereo. I then switched to N:X and was amazed, it was pulling ambient sound out of the mix really well, I could hear bike reverberations behind me and at the interview session after the race I could hear people talking off-screen behind me (where they were in reality). Switching back to DSU and it all went a bit flat/more 180 degree versus 360.
I'm hearing similar with 5.1 TV content too. (Speakers set to height, LOL).
Does anyone have a link to an 11 speaker Dolby call-out? Thanks.
