Un intéressant CR d'un professionnel, singulièrement quant au ressenti de l'effet issu d'enceintes Atmos :
sur AVS, FilmMixer a écrit:So I was lucky to be asked to the Dolby Labs Home Atmos demo today.
Three other forum members were there, and I'm sure they will all be posting their impressions soon.
A couple of things..
I've shared my thoughts over the last 6 weeks about what I've been privy to for the last 8 months, and much of what I had been told, and seen/heard, was repeated for those in attendance.
While I asked for some questions that I could relay today, I am not going to post the answer to many of them.
Mostly because I didn't ask them.
I was privy to some of the answers as others did inquire. If others that post here want to delve into some of them they will...
Dolby made it very clear today that they are going to put very specific information out (about up firing speaker requirements, detailed setup instructions, etc) in tech papers/releases starting around CEDIA.
There were no content announcements, and they stated they wouldn't be making any such statements, but would let the content providers do so at their discretion.
This was a big audio press invite, and it was really fantastic to see many people whose articles and columns I've read over the years... it was a who's who of audio journalists, and there was nothing at the event that they were told they couldn't write about, or couldn't post pictures of (the event was relegated to the screening room, a conference room and their home Atmos demo room.)
I think I counted about 32-35 invitees...
To start off, all of the attendees gathered in the Dolby Screening Room, which contains a theatrical Atmos system (IIRC it is a 52 channel system.) They started with an overview of Atmos from it's start two years ago in the cinema towards the focus of the event, the imminent release of Home Atmos, and a peek into where it will be going in the future, i.e. tablets, phones, music players, etc.
I can dispel the rumor that even some of those in attendance mentioned before the presentations started... that this is not a truly object based technology.
It is object based. I only mention it again here because there were some skeptical comments before the demos started and I've even seen it posted on other sites by a couple of other well known "sources."
After the presentation by Brett Crockett, who wrote the initial blogs about Atmos for Dolby, Stewart Bowling gave a brief summary of the state of cinema Atmos from it's launch up until today.
They then presented four trailers and a 5 minute clip from "Star Trek: Into Darkness." They showed all three Dolby Atmos trailers (Amaze, Unfold and Leaf) in addition to a Red Bull Formula One car "trailer."
After that, we took a couple of shuttle busses over to the other Dolby facility which houses a lot of their R and D and their Atmos demo room.
Everyone fit into a large conference room and was joined by Stewart, Brett and Craig Eggers, who I believe is the head of home theater marketing.
People were called out in groups of 5-6 for demos, while everyone else was able to stay in the conference room for a Q and A.
Some tidbits I learned from the Q and A..
1. I was mistaken about the Dolby Surround upmixer... It works as batpig has so thoroughly explained, and not only on setups with overheads. It is indeed the only Dolby upmixer available on Dolby Atmos products going forward. No PLII, PLIIx or PLIIz. No Cinema or Music Mode... it will include and optional Center Width control if the AVR manufacturer implements it.
2. All the objects will use spatial coding as required.
3. They didn't talk any specifics, but it was clearly stated that some manufacturers will ask in setup where the speakers are placed, distance, etc. Some will require user input for such parameters, some will gather it during audio calibration. And some will simply rely on pre determined standard layouts for their products. There has been a bit of speculation that this wasn't going to be available on these upcoming first gen products. While there certainly was no confirmation of what any of the CE's are planning on doing (except we can glean what we can from the Denon manuals) I suspect we will see varied setup options on some of these initial AVR's and pre/pros.
For the demos, we went into a room approximately 22x20x8 (I'm terrible with measurements, someone else can chime in.) It was a 7.1.4 setup.
They then played the exact same material we heard in the theater for comparisons sake.
In addition we heard some audio only demos in 7.1 and then Atmos.
And then some of those with with the ceiling mounted speakers and then the Dolby Atmos Enabled speakers...
A couple of the audio only clips played back first one way (ceiling speakers) and then the other. Others played back and they switched in the middle (with an onscreen indication of which one was active.)
There was no demo of Dolby Surround.
I'll let the others chime in their personal experiences...
I can relate, however, that the other three regulars all subjectively preferred the Atmos speakers over the on ceiling speakers. Again, most of those I spoke with were fairly skeptical before hand... not about if it would work, but how well it would work.
It's no secret that I'm really excited about the technology. I'm really honored that Dolby let me be a part of this gathering, and you are going to read all about it in the next couple of days and weeks and see what those people have to say. There are other demos for the east coast journalists and others happening very soon I was told.
It was really obvious that today was the start of the information flow and the true launching pad for this new home theater technology.
