That movie is so badass

I just finally watched Godzilla vs Kong. Pretty fun ride. Atmos was good, it the best I’ve heard but really good. The sad part was LFE rolls off at 30hz. However, it’s almost a constant entity. I’d seen mention of how quiet this track was. But at -20 I hit some peaks of 97db and found it satisfying. My son commented sayin he could feel it two rooms over. Lmao!!! Overall, good time.

Just stumbled across this. I have been very disappointed with all the current upmixers. I have some experience with Penteo from years ago that was very favorable, but it has not been licensed for AVRs and I am not about to spend that kind of money when I also would need a PC, etc etc etc.

<snip>

To answer my own question....

There's a new algorithm intended for music. Similar to Penteo in that is simply maps the pan positions of the stereo mix across the 5 speakers. It works in a different way and the results are better, but very similar to Penteo. The good news is that there's a plug in under development (I will be alpha testing) that should be a LOT less than Penteo (we shall see). Yes, I had to give up my desire to keep PC's out of the sound system, but it was $under $200 and is small enough to velcro to the side of the AVR, so overall not too bad.

Better yet, it has been licensed for a hardware version too. Now there's the holy grail! Given I now have a PC setup the hardware version may very well end up in the car. No idea when, or the price point, for the hardware. Alpha testing for the plug in started today.

For me this is the holy grail! I have been listening to a private stream of it for about 3 weeks and it is The Bomb for multi-track recorded music. I have not tried it for classical.

The algorithm is called DejaVu. I posted a first look article here so look for it.

Here's the algorithm developer's site (he's been playing with downmixing since about 2005):

(Not sure what forum this fits, but it is very exciting news. For upmixing music to 5.1 this is the only thing better than Penteo) A First Listen - DejaVu 5.1 up music mixer and Steely Dan’s Aja I recently attended the public debut of a new real-time stereo to surround up mix algorithm...

LMFAO! Had to share this with you guys! Laughed my a$$ off when I saw this it was titled a very simple explanation

Wait! Don't get it? Explanation.

Krikey this is a long thread...
I don't see myself reading all the way through this in the next few days... too much going on, but I will start. Until then, I will possibly risk rehashing old questions.

I'm going to finally add some Atmos/Auro to my system. I have the Speakers... I just need to pick the spots. This is largely an experiment. That has been my goal from the beginning. I know my room is not ideal. Hence the following:

I am not ceiling mounting (IN or ON) as I have a sloped Clerestory ceiling, all wood.

It is likely that I will upgrade to the ability to add .6 Atmos later... but for now it will be .4. The SR6012 will support:
Front Height, Rear Height
Top Front, Top Middle, Top Back

I have often seen the preference towards TF and TB. This is not ideal for me, but I could make it happen with compromised locations (not ideal angles)
It is easier to do FH and RH. This would allow me to upgrade and add TM in the future if I like what is happening.

OR

I could do a combo of FH and any of the T locations (F, M, B) (with the compromised positioning still a factor for TF and TB).

What is the most likely best experience going to be? Where is program material being sent?
I usually use Nueral X as my upmix of choice... does that even matter? Does Neural vs DA affect which speakers get used?

Thanks friends!

RynoDino my brother. Iirc, your room is not so long. I would recommend .4 top/height. The reason is that unless the room is long, and has multiple rows. There’s not much to gain. Plus! The way some tracks are processed, you might only get top middles from some tracks. I haven’t ingested all, and can’t remember all of the reasons and situ that matters.
I’m on a family vacation so I can only touch on this briefly. But iirc your room and LP would be best served with side front and rear heights.
My room is 16x24ish(iirc) and I use 7.x.4 with IC tops. This has worked very well for me, and immersive music via ATV4k is Fukkin great.
I’ll check in when I can.

Just clarifying, please...
You are recommending FH and RH
or "elevation mounts" on the side walls at TF and TB
?

Thank you!!!

Amigo!
I am recommending .4.
In the front/rear side height locations. I’ll find a pic.

This has been recommended by Ed Mullen a number of times as well. Not sure if that has any weight, but it makes a lot of sense to me as a very solid middle ground.

That;'s what I thought you were saying... just needed to be clear.

It’s good to ask. Clarity isn’t always clear! Lol

Can you tell that to my wife?

 

[Danzilla31]

Can you tell that to my wife?

Absolutely not and if your smart you won't either! Your a cool guy don't want you disappearing on us just looking out

 

[William Lemmerhirt]

Lol!
I’m sure there’s a whole thread here.

Pirates of the Caribbean- Curse of the Black Pearl (COTBP) 2003, 4K Atmos.

Atmos SQ: I had to INCREASE THE VOLUME BY 9dB. But after that, SQ is pretty good. I think better than most so-called Atmos contents. I heard plenty of overhead sounds - mainly water splashes, but other things also. I can’t put it in my “Reference Atmos” list because they could have done even better. But still solid overall.

PQ: I think PQ of COTBP is very good, but not nearly as awesome as “Dead Men Tell No Tales” (DMTNT). COTBP was shot on analog films, while DMTNT was shot using 4K Digital Cameras.

Pirates - On Stranger Tides (OST) was shot using 5K digital cameras, so I look forward to the 4K Atmos release of OST.

9dbs is a lot.

I bought all 3 of the new ones on 4K for the audio. None of them are great films, but I enjoyed the audio on all of them

Definitely no award winners lol. I still have a 1080 plasma. But since these have the Atmos tracks on regular BD, and it was a three for one, I couldn’t resist. I have purchased other 4K disks when that’s the only way to get the Atmos track. Got lucky with these. Definitely fun popcorn flicks.

Why don't you have a UHD display by now?
