Looking forward to Monday when the Atmos NDAs expire

Good idea, Markus

For those wondering, there is some juicy atmos info in the 2014 Denon S/X thread:

Denon (and by extension, Marantz) will have a whole lineup of recievers(X4100/X5200/X7200) with onboard Atmos processing included, not in an optional firmware upgrade, as was previously suggested.

News from Dolby:

http://blog.dolby.com/2014/06/dolby-...ing-room-near/

Dolby Atmos-enabled add-on speakers and Dolby Atmos content conforms to the existing Blu-ray specification. Clear as mud :)

markus767 06-23-2014 09:24 AM

Here's the current Blu-ray specs for audio (page 18/19):
http://www.blu-raydisc.com/assets/Do...0423-17830.pdf

Max. 8 channels of audio. Dolby Digital Plus could deliver 16 channels max.
Atmos is 10 channels + 118 objects max. So this would leave room for only 6 simultaneous objects?

It has been my experience that the Mods recently have been way too easily annoyed, and the character of AVS is prescribed to us users.

Atmos is very exciting to me. Though I own a Marantz AV8801 and have no real issues with using Neo:X, I find the topic of surround sound for the Home Theater to be very engaging and enjoyable.

Thanks for pulling this together!

Can atmos work properly in a room with a cathedral ceiling?

zuluwalker 06-23-2014 09:56 AM

When made available on Blu-ray with the new specs, there are plenty of movies for Atmos at home:

Will the add on modules work with planars and other non rectangular box shaped speakers?

And I'm guessing timbre matching is out the window now with these? :confused:

Being backwards compatible with existing Blu Ray players is nice :)

any news on when other avr are comming with Atmos and/or auro-3D ? onkyo got some now and denon/marantz comming with some and i wonder if anyone knows if yamaha will come with a new avr to replace the a3030. initially i wanted to buy that one but since this new surround technology and hmdi2.0 are going to be a step-up in ht it be more the worth to wait for a newer model from yammie

Pioneer has also announced some AVR's coming out.

Definitely want to know what Yamaha is going to do. Omg. Perfect processor for me would be something like their 5000 pre/pro but with Atmos. CinemaDSP+Atmos! :D

Probably as good or bad as any other format. Will it sound like what the mixing engineer heard? Probably not if your room doesn't conform to the acoustics of a dubbing stage.

Most living rooms have reverberation times that are a bit high. Now they want us to place speakers on top of existing speakers that fire at the ceiling?
The sound from those speakers will first reach the listener(s) from where they are located. Then the reflected sound will reach the listener. That reflection will be spectrally distorted (because of speaker radiation patterns and acoustic properties of the reflecting boundary). After that late reflected sound will arrive.
All in all this sounds like a bad idea and not like something that will make movie mixes translate well to home theaters or living rooms.

JD at AVS said that Atmos is the home wouldn't measure the precise locations of your speakers:

As the Atmos focus will be on the "ceiling speakers", there will be no additional angle information at all ... rather simply that the speakers will be identified as either "top front", "top middle", or "top rear" (based on the previously posted 4 configurations) and then Audyssey will do its thing just as it does with the traditional 5.1/7.1 setup.

All along I thought that half the point of Atmos was to allow for some speaker placement flexibility while simultaneously allowing for far more accurate placement of audio objects. If the home Atmos processor doesn't know the precise locations of your speakers, and just assumes their positions based on your generic layout, then other than the ceiling speakers, what makes home Atmos better than theatrical Atmos down-mixed to a channel-based mix for HT?

jdsmoothie 06-23-2014 06:25 PM

Well .. the ceiling speakers are a new element in the mix. :)

Yamaha will have (3) AVRs with Dolby Atmos...
Will be shown @IFA and CEDIA, ship late-September....

Just my $0.05... ;)

Nice! Then the question is if they are of the Aventage quality or if these three are in the <$1,000, limited in total capability models.

Should be interesting. I'll look out for them at the show!

I couldn't imagine Yamaha (or any manufacturer for that matter) starting Atmos in anything less than their top tier models to begin with. But stanger things have happened I guess.

Scott Simonian 06-23-2014 10:00 PM

Well actually by far most of all the Dolby Atmos AVR's announced this far are in the sub $1k market. Just a couple 'high end' and 11.1ch or greater so yeah...

I guess we'll see. I'm hoping for something like a 3030-ish but with Atmos. At least. Their a5000 with Atmos (and an XLR for sub) would be sweet.

Really, that's the big question. If Dolby had to dumb Atmos down to 1) squeeze it onto a normal Blu-ray and 2) Appease the cheap-ass manufacturers who didn't want to spend the money on new hardware designs, the faster processors and software to implement object surround properly... then what are its sonic advantages to any old 7.1 channel based system besides the in-ceiling add on speakers?

"Gravity" in Atmos was absolutely spectacular, but it took a heck of a lot of speakers to make it happen. Many of the press demos for at home Dolby Atmos and DTS-UHD had a lot more speakers than the 7.1+4 we're seeing. More like 20 some.

I've been saying this in other threads and I'll say it here: I'd like to know what these Dolby Atmos enabled soundtracks coming to Blu-ray are actually capable of doing besides what we're seeing in these almost rushed to market first gen products.

Huh? Every single one of the Atmos-enabled products announced today by Onkyo, Integra, Marantz and Denon were $1000 and higher. Pioneer didn't provide prices for their Atmos models, but it's very likely those will also start at $1000+. The only sub-$1000 Atmos receivers are the previously announced Onkyo models that will get Atmos through a future firmware update, but there are only two of those (at $699 and $899).

So, if you replace "by far most of all" with "very few of" in your quote above, then yeah, you're right.

yeah i'm hoping the same. considered a a5000 pre but the pro amp is not that great and buying some other brand amps would cost a lot with not that much gain for the money in better sound over a a3030. if they come up with a a3040 or so with atmos/auro-3D i jump right in. or maybe a firmware upgrade for the a3030 would even be better costwise

I have a hunch that Auro3D is a non-starter. DTS-UHD on the other hand...

No, I think they wanted to see what Dolby came up with first. It's always a game of oneupmanship.

AURO 3D is dead in the US! Unless you have $20,000 and get a DATASAT

Remember Betamax vs VHS; HD DVD vs Blu Ray; SACD vs DVD Audio well that one is not a good comparison except for classical music :D

not perse, the disney studio's allready have adopted auro-3D and some other studio's as well. the avr supporting this are going to be a bit more expensive then atmos i'm afraid. i've heard both and i favor the auro-3D.
edit: didn't see the added text.. but yes i like dts too. especially the higher bitrate and clearer sound of it.
