Trinnov re-mapping can use height speakers to make the soundstage image at the proper height, but it is not extracting overhead height information.
I am not the only one that played with the height channels, the owner set gain at +1, a dozen people heard what I describe. That is the only way to prove to anyone that they were hearing a 3D sound system, play iroman 3 house destruction scene, play oz transition scene, play wwz helicopter, play star trek jetpack invasion sceneDo that and hear $hit(with the exculpations of reverend censor Canga) hurled over your head.
Sanjay I wonder how well your ears are calibrated to your encyclopedic cerebrum. I defer to you to digesting the theory and being able to interpret it for the more laymen to understand, it is comforting to know there are people like you Im just hired to buy high tech and try it, we hired Curt who has a doctorate level pracvtice on acoustics. At the end of the day I make it my business to take theory with a grain of salt, HT is far more art than science and by art I mean experimentation too. How do you explain then that what was heard? And it is very important to be hearing these signals while wearing 3d glasses to compare the acoustical cues (distance from screen+apparent acceleration+ xyz trajectories) at the same time with paralax changes of the "sound objects y axis pans" [to use liberaly the term for an element on the screen being hurled to the back or viceversa].
Are you preposterously suggesting that we will only hear items ON THEIR WAY to the surrounds from the front/ARRIVING TO THE REARS and viceversa but that the heigh during the overhead transition is INTERRUPTED lost? Cause it ain't the case I hate to tell you. The trinnov remap filled that gap with what sounded like the Harman system on regular 7.1 disc but in contrast when playing certain discs (those made from Atmos and Auro masters) in such discs sound "on their way to the surrounds" traversed through those speakers after they left the fronts and before they arrived at the rears. Keep in mind these speakers project very far field and their arrival time was set forward (as they should)
If it walks like a height, it smells like a height, and it talks like a height, I call it a pseudo height. For you to profess armed with academic knowledge that that particular system is completely incapable of that feature
is nothing more than academic trolling, because you too are wrong.
Call it a side effect, a coincidence, an opto-acoustical illusion, or just the acoustics/electonics mix in that room. But the height channel APPEARED to fill the logical speaker gap in correlation with the parallax. When the height channels were turned off the image collapsed leaving a hole above.
Lets try the reverse elimination process:
So kindly tell me where the height info is coming from in a 7.1 mix(mastered in one of the high order systems) in all four of those systems.
What do you think happens to that signal which 3 out of 5 times IMO is panning front to back/side to side/ vice-versa? [of sound objects: Helicopters being the ubiquitous example.]
Using your above definitions [which in all fairness is biased against AURO through ambiguity- if you do not know don't pretend you know through omission] Like James Cameron said to me "if you are going to come to me with a critique, arrive prepared" ( I merely had lost my train of thought as I realized who I was lecturing
Where do you think you will hear it? because IN PLIIZ info on its way to the surround channels or arriving to front channels from back channels sounds to me like it could pop in the heights. So that has to be experimented as far as I am concerned.
The DTS definition also points to me like It will show up there (ya hear me Bland).
By your own comments you like the auromatic so if it is not filling that hole above what the heck is it doing?
The people that have heard Neils have had only high praise for the Barco auro. You know what, we will soon hear from people that will be able to say Sanjay was right Peter was wrong on Auromatic (and yes with questeds), or plIIz or Neo x, cause I dont need anyone validation on what is clearly perceptible with Trinnov remap [and yes Crucify me and the owner for finding a 1 decibel bump on those channels enjoyable and natural] in that system/room.
Please placate our inquisitiveness and tell us your best guess: We know of your reticence for speculation (although I caught you correctly speculating that auro will sound better at home due to lack of speaker array induced image dilution- Bravo), please indulge me.
Where will the height information come out of on a heights channel equipped system using those four methods with discs mixed down from and original auro/atmos mix? Si Vous Ples
