Mods are already getting annoyed by the numerous discussions about the upcoming Atmos feature in AVRs. So lets give this new format a home of its own in this thread.

I'll update this post with news as we go along.

First, here's some general information about Atmos so everybody is up to speed:

Looking forward to Monday when the Atmos NDAs expire

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.

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!

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

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

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:

Audioholics article talking about these modules (and more) back in Feb.

http://www.audioholics.com/editorials/dolby-atmos-home-theater
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?
