Author Topic: How long will Dolby Atmos last? Marcel Birgelen Film God Posts: 3357 From: Maastricht, Limburg, Netherlands Registered: Feb 2012 posted 04-24-2015 03:54 AM                     quote: Lyle Romer What makes AC-3 "different" is the cross channel bit sharing based on psychoacoustic masking. It isn't just 5.1 channels compressed. It is 5.1 channels compressed at varying levels of compression depending upon what the other channels are playing. Well, yes. And you can essentially do the same with MP3 and stereo (L + R) tracks. Dolby had to cut quite some corners to make it a feasible format to fit in between the sprocket holes and include some error checking too. Those lossy compression algorithms are not designed to reproduce the exact wave that went into them. They're developed to reproduce sound that, to a varying degree, sounds indistinguishable to your ears and AC-3 applies this to all 6 channels. Try to listen with a headphone with one ear to a joint-stereo MP3, it sounds really awful, especially those compressed with older encoders, that didn't switch to "L+R stereo" for the complicated parts.  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft.

I did an early demo of Kintek and sonic results where good to awful. Orban chips where used in RGM stereo systems to give better channel separation….history repeats itself.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 04-24-2015 10:32 AM                     Never saw a RGM with Orban but Christie used it as did Opu360  |  IP: Logged Jonathan Goeldner Phenomenal Film Handler Posts: 1360 From: Washington, District of Columbia Registered: Jun 2008 posted 05-27-2015 07:46 AM                     I have no idea what or why Universal decided 'Furious 7' and 'Jurassic World' to not be mixed in Dolby Atmos ... what's that all about?  |  IP: Logged Jim Cassedy Phenomenal Film Handler Posts: 1661 From: San Francisco, CA Registered: Dec 2006 posted 05-27-2015 09:37 AM                     Jonathan- The semi-cynical part of me says "follow the money". I've been able to observe a couple of ATMOS mixing sessions and it can be a very time consuming process to do some of the more complex ATMOS mixes. Time is money. Perhaps the studio bean-counters didn't think they'd get a decent return on their investment in the extra post-prodcution time/labor costs. Or perhaps those films had already gone way over their proposed budgets during production, so a decision was made to 'fix the budget in post" by not doing the ATMOS mix. Of course I'm speculating but stuff like this happens. (And yes, even < I > was surprised to see those two releases with non-Atmos sound)  |  IP: Logged Jonathan Goeldner Phenomenal Film Handler Posts: 1360 From: Washington, District of Columbia Registered: Jun 2008 posted 05-27-2015 11:07 AM                     given these are tent pole franchises for Universal - yes, it's very surprising and disappointing. The sound aspect of post production always seems hit or miss. Sony hasn't embraced 7.1 let alone Atmos - thankfully 'Pixels' will at least have the latter.  |  IP: Logged Aran Clifford Film Handler Posts: 3 From: LONDON, ENGLAND, UK Registered: Mar 2016 posted 03-20-2016 12:57 PM                       Hi all, Its been really interesting looking at all your posts about Atmos and its competition. Im currently undertaking a dissertation in surround sound formats and what the future could be for these. I've put together a quick survey (about 7 or 8 questions) to see about peoples feelings with these formats. It would be great if you could help and spare a couple of minutes to fill out this survey. It would help me greatly and it might just be interesting for all of you too! https://docs.google.com/forms/d/1GZMtUEr4tqlEEnOPYCrNFRgZEhgh-ZES-mCKHJD9K6I/viewform Thanks!

Object Based Formats Channel Based Formats Hybrid Formats Any additional comments  |  IP: Logged Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 03-20-2016 10:27 PM                        The survey is missing one essential question: "Do you care about the difference between the various cinema sound formats currently being used in movie theaters?" Yes, I am passionate about movie sound I like to hear good sound but I don't necessarily like the upcharges for it No, as long as I can hear the dialogue I'm fine  |  IP: Logged Paul Linfesty Phenomenal Film Handler Posts: 1383 From: Bakersfield, CA, USA Registered: Nov 1999 posted 03-20-2016 11:25 PM                     Is Dolby ATMOS currently the only object-based system out there. I ask this because the Maya Cinema in Bakersfield is "transforming" one of their big screens with "MPX" (Maya Premium Experience." The website says it includes: MPX 3D sound has amazing audio quality! MPX clarity of sound effects is phenomenal and delivers total immersion into the film. MPX sound is delivered anywhere in the theatre, including overhead. MPX sound can isolate any speaker and bring a sound to it as you would hear it in real life. No matter where you sit, MPX sound envelops you, and its rich clarity brings the film directly to you. ◦AN INCREDIBLE IMMERSIVE EXPERIENCE IN SOUND AND VISION! ◦UNCOMPRESSED 3D SURROUND SOUND ◦PURE ALL DIGITAL PROJECTION ◦100 THOUSAND AMPS OF POWER – 60 CHANNELS OF GLORIOUS SOUND – MORE THAN 70 SPEAKERS, INCLUDING OVERHEADS – I'm thinking they mean 100,000 WATTS of power. There is NO mention of this being a Dolby Atmos system, and they already have had one in place since December 2013 in their other large auditorium. But their description sure sounds like an Atmos system, unless there are others that can emulate it.  |  IP: Logged Marcel Birgelen Film God Posts: 3357 From: Maastricht, Limburg, Netherlands Registered: Feb 2012 posted 03-21-2016 01:03 AM                     There is DTS:X, which is a competing format to Dolby Atmos. But it doesn't mention object based audio anywhere, so it could also be Auro 3D, although then their claim of uncompressed audio would be false. quote: In the last year, which formats have you watched films in? 5.1 7.1 Dolby Surround 7.1 Auro 3D Dolby Atmos DTS X Other: You could fit anything under "Other", but we're missing tons of options here, like all analog options and stuff like DTS-6, DTS-8, SRD, SRD EX and IMAX (which could also be differentiated). Also, what's supposed to be the difference between 7.1 and Dolby Surround 7.1? And what happened to Dolby Surround 5.1? Also, wouldn't it be better to ask for estimated films watched in a given format instead of just to tick boxes? And in addition to what Mike already proposed, I'd ask people if they're actually choosing to see a film in a certain location that offers it in one of the "premium" audio formats. The option "Do you think the future of Film audio lies in..." is also missing at least one essential option: "I'm not sure". An other one could be: "I don't care".  |  IP: Logged Paul Linfesty Phenomenal Film Handler Posts: 1383 From: Bakersfield, CA, USA Registered: Nov 1999 posted 03-21-2016 09:08 AM                     quote: Marcel Birgelen But it doesn't mention object based audio anywhere, so it could also be Auro 3D, although then their claim of uncompressed audio would be false. Well, it does say that any sound can be isolated in a single speaker.  |  IP: Logged Mitchell Dvoskin Phenomenal Film Handler Posts: 1869 From: West Milford, NJ, USA Registered: Jan 2001 posted 03-21-2016 09:12 AM                     I suspect sound will never be a motivating factor for the majority of the public. When they go out to a movie, they can see the picture and our eyes know good from bad. While our ears know good sound from bad sound, they do not have a frame of reference to judge if what they are hearing sounds better or worse than the same film playing in a different sound format. Remembering, the majority of the public is still listening to television via the cheap built-in tv speakers rather than a home theatre sound system. I find it hard to believe that they will pay a premium for better sound.  |  IP: Logged Mike Blakesley Film God Posts: 12767 From: Forsyth, Montana Registered: Jun 99 posted 03-21-2016 11:20 AM                        I've had people over the years ask how many "watts" our sound system is, or how many speakers do we have, that kind of thing. But nobody has ever asked about brand names or numbers like 5.1, even though we play a Dolby logo before every movie.  |  IP: Logged
