But with no theatrical mixes at all so far, it isn't easy to see where the content is coming from.
"Immersive audio" and "object based audio" are NOT synonyms; remember that the intent of home theater object based audio is to deliver improvements in three distinctly different ways: "immersion", "ubiquity", and "personalization". For examples, see this DTS press release January 2014:DTS-UHD Benefits:
Environmentally compensated audio rendering allows consumers to hear audio directionality and dimensionality more precise than ever before possible
Object control enables consumers to interact with key objects within the audio mix and adjust them to preference
Customized rendering designed for arbitrary speaker layouts enables consumers to adapt their AV system to their own home environment rather than pre-determined speaker layouts
... or 'many' papers and articles concerning Fraunhofer’s New Interactive And Immersive Audio System for Television Broadcasting, and 'related' entities|concepts The MPEG-H Audio Alliance, and the mpeg-h 3D audio codec.
With it's theatrical cinema origins, Atmos directly addresses "immersion", but in its current incarnation does not appear to support "personalization" at all, and while "immersion" is presently only of interest to a small audience with multi speaker systems, "personalization" is applicable to all audiences even those with only 2.0 playback systems, e.g., a TV. For example see: MPEG-H Audio - The New Standard for Universal Spatial / 3D Audio Coding (link):"Using audio objects or embedding of objects as additional audio tracks inside channel-based audio productions and broadcast opens up a range of new applications. Inside an MPEG-H 3D audio bitstream, objects can be embedded that can be selected by the user during playback. Objects allow consumers to have personalized playback options ranging from simple adjustments (such as increasing or decreasing the level of announcer’s commentary or actor’s dialogue relative to the other audio elements) to conceivable future broadcasts where several audio elements may be adjusted in level or position to tailor the audio playback experience to the user’s liking..."
My understanding that the (English language) dialog for current 5.1|7.1 channel based movies is on a separate stem to allow for alternate language dubs. It seems to me that any such movie--which might previously have been released as DTS-HDMA 5.1--could now 'quickly' be released as DTS:X 5.1 + 1 Dialog Object (with legacy DTS-HDMA 5.1 capability).
sur AVS, SoundChex a écrit:Roger Dresler a écrit:That question being: >>Also, as with DD and DTS today, would most new BRDs in the future not contain an ATMOS mix and DTS:X mix?<<
Most BRDs today contain only one lossless soundtrack. I expect that to remain the case.
Of course, one "new" option available when starting from a DTS-MDA theatrical mix might be to render Neo:X 11.1 and Auro-3D 9.1 channel versions of the movie along with the usual 7.1|5.1|2.0 instantiations, all of which might be ensorceled into the legacy DTS-HDMA 7.1 component of the DTS:X soundtrack . . . to provide maximum added value during legacy playback on any non DTS:X capable AVR.
sur AVS, SoundChex a écrit:Roger Dresler a écrit:Within the confines of a 7.1.4 speaker system, where all three systems (Auro-3D, Atmos, DTS-X) can share all the speakers (a fantasy of mine), I do not see any reason why there would be any material difference in the reproduced sound, regardless if the source were originally mixed in Auro 13.1, Atmos, or MDA. The mixes themselves might sound different, having been made in different rooms by different people, but as delivered through any of the three systems, they would not sound different. Where the playback results would vary is once several more speakers are added, or the 7.1.4 configuration departs from the normal locations.
Just for the record, Roger, my fantasy is bigger than your fantasy!![]()
I'm hoping that it will be possible--within the confines of a 7.1.4 speaker system--that all four systems (Auro-3D, Atmos, DTS:X and ATSC 3.0 TV audio) can share all the speakers (a fantasy of Roger's (TM)). This could be less problematic than is immediately thought, as the Auro-3D speaker layout may be "close enough" to the model ATSC 3.0 TV 7.1+4 speaker layout . . . however, it might suggest that "more weight" should be attached to ensuring (closer) conformity with the Auro-3D 9.1 speaker layout!
