Dolby Atmos Theatre System - Page 18

post #511 of 922
Watched both Oblivion and Iron Man 3 in Atmos and I 100% agree with your statement Sanjay. I could hear the pans Iron Man 3, but I had to listen for them which is not what you want to be doing when enjoying a movie. I don't think we have seen Atmos really stretch it legs yet as to how it can really enhance the cinematic experience.

The Denver area finally got its first Dolby Atmos installation in an AMC theater with an ETX screen.

The most obvious changes in the auditorium were two rows of five speakers on the ceiling and six(!) large subwoofers hung from the ceiling in the back of the theater. The movie was G.I. Joe in RealD XL 3D.

I sat in the middle/middle of a virtually empty theater to critically listen to the new sound system. The “Leaf” logo had a nice dimensionality but lacked the ethereal any-point-in-the-room quality I was expecting. The movie made constant use of the (very hot) surround channels. I didn’t exactly have to strain to hear the screen speakers but I’ve never heard surrounds turned up to such a high level. I chalk it up to “new toy” syndrome where AMC wanted to make sure their upgrade was noticed. The bass was exemplary with the rear subs quite obvious at times.

I was surprised that I only heard the side surrounds from speakers directly to the left and right of me. I didn’t hear sound move along the wall as things panned front to back or vice versa.

From the White Paper link in the first post of this thread, it appears that any speaker/channel/amp configuration is okay in an Atmos installation:

“In contrast to using all 64 output channels available, the Dolby Atmos format can
be accurately rendered in the cinema to other speaker configurations such as 7.1,
allowing the format (and associated benefits) to be used in existing theatres with no
change to amplifiers or speakers.”

The question is, did AMC reconfigure it’s surrounds to “one speaker-one amp” or did they just add the ceiling and subs and call it day? How can a person know if they’re going to a full-blown Atmos theater or one I would call Atmos-Lite? Anything in Dolby licensing that requires one surround speaker per channel before an auditorium can display the Atmos logo?

Unrelated question: How are most surround speakers wired to one physical 5.1 or 7.1 channel? If I’ve got nine right surrounds on one wall, wiring them in parallel would drop the impedance too low for the amp. If they’re in series it’s too inefficient. Do most theaters already use more than one amp for a set a surrounds?

John

It kind of depends on how much money the cinema wants to put into the sound system. Most cinemas run about 4 surrounds per amp, some more. In a situation with more than 4 per amp they will run them in series. In a cost no object cinema they may run two per amp, or maybe 4 on a 4 channel amp. Ive seen simple small cinemas that run a 4 channel amp for the stage, LCR+sub, and a two channel amp for the left surround and right surround, for a 5.1 install.

When I saw iron man 3 at the amc imax in rockaway nj in the end credits they mention dolby atmos instead of Dolby digital....could this force theater owners to adopt this brand now that everyone who waited until the bonus scene heard about atmos?
post #514 of 922
No, so many did not even notice that DTS was replaced by DataSat for years now and a lot of them are enthusiast. The folks that waited for the credits to role were looking for additional scenes not to view the audio information.
post #515 of 922
Yeah. Spoiler alert...hulk in human forum talks to tony stark before the studio logos appear, and the final credit says that tony stark will return. Seems that sdds is still around but very few 8 channel mixes around.
post #516 of 922
You may want to use the Spoiler feature to mask that.

I wonder if Atmos will lift Dolby's stock..seems that it's doing quite well YTD with the rest of the market. As the cost of Atmos will decrease soon, more theater operators will adopt the system.

Since Dolby doesn't sell speakers or amps, the vast majority of profit from most installations will go elsewhere I would guess...

I don't think the success, or failure, of this format will have a large impact on their bottom line either way.

I have to weigh in here. After giving my best friend a hard time about checking this out, he finally did. Be careful what you wish for, because he gave me an earful. The theater in Las Vegas (The Palms?) was according to him way to heavy on the LFE. It wasn't even close to subtle. I asked him if there were any points in the movie that he could notice a difference. His reply was not really, because the LFE was almost always present. I guess this is a YMMV, but I think it will be a long time before my friend attends another ATMOS movie.

The movie was Man of Steel.
post #522 of 922
Just got back from seeing 'Man of Steel' in Atmos with a couple of friends from out of town. We were all impressed with the mix. Not as much overhead as I would have liked, but what was there was definitely noticable. There was lots of sound panning around the theatre. It was at the Arclight in Sherman Oaks, which has tame bass compared to the nearby Atmos theatre in Burbank, where the bass is so overcooked that you can hear stuff inside the theatre rattling (so distracting). Even the Dolby 3D looked good (compared to my previous experience with their anaglyph system).

That's encouraging on both counts -- the mix and the bass!

More from Scott Wilkinson on the 3D technique:
Quote:
The whole idea of color filtering has led some to call Dolby 3D "super anaglyph," because each eye sees different colors. However, I think this characterization is misleading—anaglyph most commonly refers to those dreadful red-and-blue glasses that yield a very poor 3D image. I've seen Dolby 3D, and the experience is nothing like traditional anaglyph.

Happy belated one year anniversary dolby atmos!!! Monsters university is the current and 45th release to be mixed in atmos. By the time the hobbit part ii comes out...the number of theatres with atmos will grow just as the adoption rate for 7.1 home theater will grow.

Does it?
post #526 of 922
Nope. Remember when dolby stereo came out in 1976? There were a few theatres with that equipment. The one two punch of star wars and ce3k raised the bar for theater adoption of dolby stereo. Much like how digital surround sound caught on after batman returns, jurassic park, and to a lesser extent last action hero.
post #527 of 922
That was then but this is now. Do you have actual numbers? I have the feeling that people have lost interest even in two channels.
post #528 of 922
If I understand (some of) RealD's new “LUXE: A RealD Experience” a premium large format (PLF) initiative, there would appear to be a requirement also to install 3D audio for full auditorium compliance. It will be interesting to see if a possible competitive large screen format war 'somewhat linked' with 3D audio accelerates|slows overall 3D audio theater penetration, or has any effect on the current ratio of Dolby Atmos vs Barco Auro-3D theater installs.

Any word on when amc in rockaway gets atmos? Seems that the large screens (non-imax) have 7.1 audio while the medium and small screens have 5.1. All dolby.

As a side note, we did the Atmos mix way after the fact, and didn't have the ability to go back in and separate out as much as I would've liked..

Think of it as Atmos Lite, but I would still tell anyone if they had a choice to seek out the Atmos presentation first.. looks like it will be on about 15 screens nationwide.

In reagards to D-Cinema presentations, 5.1 and 7.1 are not "Dolby."

Even though Dolby has penned the Dolby Surround 7.1 moniker for some presentations, the audio on the DCP is straight PCM, nothing Dolby about it.

I saw my first Atmos production last week, Man of Steel at Cine Capri in Scottsdale AZ.

It really added a lot to the production, it's the first movie I've seen since I got more "serious" about my home theater that actually impressed me (and of course not because of the actual movie). Usually I go to movies and all I can think is... this would look and sound better at home! Clearly wasn't the case with the Atmos sound, very enveloping and it does a great job of spacial awareness... moving sounds about the room in a manner that coincides well with whats going on in the video presentation.

I would definitely be more prone to seeing additional movies with Atmos sound, whereas the only reason I ever go to movie theaters now is social convention. LOL It just doesn't make a whole lot of sense when you feel you own home is as good or better without all the aholes... and you can buy the BD for less money and watch it infinitely.

pcm is pure digital clearness....and sounds better than a dolby digital/dts/sdds 35mm print and even dolby/ultra stereo.

I guess you are saying they are different mixes otherwise what is the difference between PCM and Dolby that gets converted to PCM?

I concur on all points.

You’d think that someone like me, connected with “the industry” all these years, would have been among the first to hear these new-fangled 3D audio systems. Yes, I heard the 24-speaker system at SRS Labs many times as they developed MDA, but I mean hearing it in a real cinema situation.

Well, thanks to the gracious invitation of Marti Humphrey at The Dub Stage, and his accommodating clients, I got a full on demo of Auro3D, including clips from a movie mixed on the premises, Oz The Great and Powerful. First time I’ve been to a movie named to describe the sound mix, but hey, that might be the best thing about the movie (will see it in full next week on BD). The sound was both great and powerful indeed!

The Auro 3-layer approach was seamless as it reached up and over, able to convey both space and detail. My concerns about “hot spot” overhead imaging were eliminated by the use of a cluster of 4 speakers to cover that. The effect felt completely natural. A big, seamless space.

Later that night, I had a chance to get my next initiation, this time to Atmos. I’d already seen Man of Steel in a conventional cinema, so being able to compare it was too good an opportunity to pass, even though MoS does not improve with repeated viewings. The cinema was Regency Agoura Hills, which also offers 2 full rows of D-Box seats! We sat dead center in the row right in front of those.

First off, I felt the cinema was superbly tuned. Smooth response, no jacked up bass or elevated volume. So that put me in a positive mood right off the bat, as it was better than my first experience with MoS where the sound was still good, just not as good as this.

We were able to notice the attributes of Atmos. Certain off-screen sounds were pinpointed, and ambiences and flyovers were elevated. The ambience bubble was there. And yet it lacked in contrast to what I heard from Auro in this apples to oranges comparison (different movies, different rooms). There was nothing overhead. It felt more like giant surrounds. So yes, Atmos sounded better than a normal cinema, and I’d go again given the choice, just as I’d go to Auro if that were available.

D-Cinema accommodates a few configurations of channels, with 5.1 being the vast majority and 7.1 gaining in use. The audio format is AES-EBU 24-bit 48-kHz PCM.

Dolby sells cinema processors that manage the B-chain (decoding for various 35mm audio formats, equalization, levels, time delays). They also sell cinema servers that deliver standard Digital Cinema soundtracks to the processor. And their new cinema processor adds Atmos capability, which is once again a proprietary audio format that only Dolby cinema processors can use.

Really? When Zod first addresses the Earth, the shots at the military base had his voice directly overhead asthough coming from PA speakers. That was the most obvious example I heard, though there were others (Coast Guard helicopter leaving the burning oil rig).

My experience with Auro3D has been the opposite of your's: the two movies I saw (Red Tails, Rise of the Guardians) had me wondering whether the additional speakers were even on. Maybe those mixes don't translate from the studio (where you heard it) to commercial theatres (where I heard them).
