Still getting DD+ with the integrated FN in my Roku Premier Plus (I also get DD+ Atmos on this device with VUDU and APV); I believe newer Roku devices no longer have the integrated FN, but rather a standalone FN app, so maybe with those device?

Does it make any difference if it's HRA or MA as long as the bitrate is high enough? Has anyone ever proven they can tell Master-HD MA from Master-HD HRA? I've never seen ONE DBX test to prove anyone could tell 256kbps AAC from the lossless master or 320kbps MP3 even yet the belief goes on they're no good.

24/96, 24/192 sound better...no proof and the science doesn't even support a difference with really good recordings, but people believe they are better too and are willing to put up with copy protection, watermarking, etc. (the latter is typically in the audible signal) to get it yet they're usually not even interested in seeing if they can hear a difference or not first. I guess like sugar pills if it makes you feel better, take 'em anyway.

Probably not.
Or if there is a difference, it is subtle and not revealed under usual listening conditions.
But we humans always want the "best" if it is available even if the difference between the "best" and "good enough" is marginal.

Also, the "best" is an ever-moving target.
Today's "best" is tomorrow "old", "classic", "obsolete" and "I don't want that!".

Well Go USA is only home video label using audio objects on their DTS:X tracks (7.1.4 channels + 5 objects). Their last two home video releases ('Master Z: Ip Man Legacy' and 'Shadow') have Dolby Atmos soundtracks. Make of that what you will.

I don't see how it's funny. I drive a $12k system with a Shield. There's nothing better out there that I know of to run that type of file.

The shield might imply they're breaking copyright laws streaming dumped discs or whatever? Even with the new 8.0 software, the Shield still lags the AppleTV for Atmos in Netflix (now it does 640kbps, they exclaim, the same as some studios!). Yippee. The same as Dolby Digital lossy on BD from a decade ago....

I looked for some DTS streaming titles in Fandango Now, but couldn't locate any on the Shield. I have no idea if any streaming boxes support DTS in Fandango or not, even if they're there.

Or as MagumX says, it's simple high-end snobbery that can't admit that quality only comes with a high-end price.

It reminds me of the excellent Dalite Hipower screen, which was so reasonably priced as to be ignored by many high-enders.

If anything with the "high-end" I'd say price has less and less to do with quality it the further the price goes up and the more it has to do with making apocalyptic levels of profit margins. Even speakers, where the most difference typically occurs starts to get absurd when you cross the $10k threshold, IMO. It shouldn't cost $50k a pair to get good sound, at least not from the speakers. The problem is that even the best speakers can sound bad in a bad room and the room can take +/- 1dB rated speakers and swing them 8-12dB easily in some cases, especially in the bass regions.

One of my favorite brands (PSB) routinely makes speakers rated within their nominal bandwidth in the +/- 1dB range, but getting that in an anechoic chamber and in an actual room are two different things. Room correction can help a lot, but it can't fix giant "holes" in the response (i.e. you can turn down peaks much easier than correcting pits) so bass traps and other treatments might be necessary. But the notion that buying more expensive speakers will make it sound even better is flawed by the room as the same room will cause suck-out in the same bands save perhaps from some speciality speakers (Focal Whispers come to mind) that attempt to foil the room reflections, etc. within reason (even then the bass region can still be an issue). Now are you going to get better room response with $50k speakers? I find it doubtful. There are other measurements, but frequency response is a pretty good indicator of even response to my ears.

But if you have a really nice room, the response can be good even without room correction (I'm lucky to get +/- 5dB overall in my home theater, mostly due to some suckouts in bass where I'll need traps to even it out), but I have no such issues in my music room where the back of the room acts like trap on its own. The Carver AL-IIIs are only rated +/- 3dB to begin with and as you can see from the REW graph, it almost achieves that in the actual room. (red graph is where I actually like the bass set, which gives a smooth downward slope to flat, but I also took measurements with the active crossover set to flat on the green curve). With bass, it's +/- 5dB, but above 200Hz (ribbons only), it's +/- 3dB and without any room correction and those are dipoles. I've only come close with my home theater stereo mode recently after more treatments and room correction, I think it now sounds comparable in 2-channel (+/- 5dB overall, with most within +/- 2.5dB save the 680Hz dip; the graph is "reference" so it slides down over 10kHz, which I prefer to "flat" there).

I'm really confused when it come to setting up our Yamaha AMP A3050. Now the question I would like to ask is When you set up your Amp speakers for DTX or DTS Neural X do you set them up as HEIGHTS NOT OVERHEADS (overheads the one cut through the Ceiling) and on Dolby Atmos you set your speakers on OVERHEADS (Ceiling) not heights Is that true.


Thanks

Yes, what you describe is by consensus the optimal way to setup the Yammys.

If you read carefully you can see that they do not mention ANY source AT ALL - no Blu-ray player, no STB, no streamer, no HTPC, nothing - only the components used for getting the image and audio in the demo room.

DD+ is nothing like lossy DD from DVD.

It's "NOTHING" like it? That's a bold statement when we're talking about two different LOSSY compression formats. An update to the compression protocol hardly makes it night and day different. It's STILL a lossy compression format. It's purpose is to save bandwidth (money) in transmission. Even poor quality compression protocols sound good if you give them enough bits, after all. Until Netflix updated their server end transmission, it mattered not. I'm not downplaying Netflix's higher quality audio transmissions they now offer. My POINT was that the Shield has not updated the App to something the AppleTV 4K has had now for many months, which is not only DD+ underneath (The ATV converts it to PCM internally first), but Dolby Atmos support for shows like Altered Carbon. I probably should not have used the term "DVD" there as most DVDs had very low bandwidth Dolby Digital on them, where you could potentially hear a quality difference. With the Blu-Ray DD rate of 640kbps, however, I cannot tell the lossless track from the lossy track in casual listening, certainly not to where it bothers me.

However, I'd LOVE to see someone do an A/B/C style 3-way comparison between 640kbps DD and a similar streaming rate of DD+ and the LOSSLESS version (which is present on most Blu-Rays and so it's easy to get a signal to compare. It's hard to get a DD+ version from one of these discs since they mostly use DD, but you can easily make a DD+ track using software tools). The bandwidth is neither here not there to the consumer that has enough of it. The question is whether the consumer can HEAR a difference between 640kbps DD, DD+ (at whatever rate you want since I maintain 640kbps is transparent) and the lossless version. I'm not saying someone can't tell the difference (I've certainly never heard one at the 640kbps DD rate at any rate; I'd be less sure of lower rates, but that was no my original point).

My original point was not to compare compression ratios, but to point out that the update to the Shield does NOT include Dolby Atmos support from any major app like the AppleTV has and thus it's INFERIOR (no matter how high the bitrate) to the AppleTV's capability when watching the same Movies Anywhere movies or even Netflix. If I watch Altered Carbon on the AppleTV 4K, I get Dolby Atmos (with a DD+ carrier converted to PCM). With the Shield I get 5.1 (not even 7.1) with DD+. THAT is what I'd call "nothing like" (actually I wouldn't use THOSE words even there as of course they're "something alike", just less rendered channels). In fact, until I got my newer Marantz 7010 AVR to replace my 2006 AVR, I could not even get more than stereo from the Shield as unlike the FireTV, it does not convert DD+ back to DD for older equipment leaving me with 2-channel sound. Why? Its saved NVidia a few cents per unit in licensing costs to convert to the older DD. I can blame Dolby. I can blame Nvidia. Either way, I had 2-channel sound until I upgraded the AVR.

In other words, I don't care about the Shield update changes because I'm not going to choose 5.1 over Atmos (when I have both devices present) and thus the Shield apps will NEVER get used.

Dolby has said in the past (during the HD DVD/BD wars) the performance of DD+ and DD @640k bps is the same for all intents and purposes.

The main purpose of using DD+ is to get better 5.1 performance at lower bitrates (perfect for streaming) than standard DD and to remove the max 5.1 channel limitation.

So I've been testing my new Samsung Q90R soundbar on a bunch of DTS X and Atmos 4k Blurays. My findings are DTS X movies (Jurassic World, Fallen Kingdom) for examples are notably quieter than all my other Atmos movies like Kong Skull Island, Pacific Rim, Ready Player One etc. I had to turn up the master volume 4+ on DTS X movies just to roughly equalize the Dolby Atmos movies. Is this what everyone's been getting?

I found that the Harry Potter 4K BD discs with DTS:X had very good audio at my normal listening levels. Then the recent release of Stand By Me in 4K BD with Atmos had a lower volume level than normal for me. It appears that this probably varies with titles and studios, but never out of easy adjustment range with my setup. It will be interesting to see what others have experienced.

I start at a general baseline MV level. Then adjust/optimize the MV level for each movie, concert or documentary to my liking as I experience it.

I use the comment section within the bluray.com app within the media title to keep track of the final MV level and DSP mode applied. It makes it easy the next time you enjoy the media title. Just dial up to the MV level and the DSP mode if any and enjoy. It also increases the enjoyment for ALL involved.

No need to serve cheese with the whine Because your not tweaking things.

That has not been my finding at all. Disney titles 7.1/Atmos are usually the quietest movies I come across. AppleTV 4K titles often seem much lower volume than discs as well, but there have been a few exceptions in both directions. I haven't noticed Atmos/X being louder or quieter on an overall average at all. Most movies sound best here at -9 to -6dB. Some older titles like Raiders of the Lost Ark (THX BD) sound good at 0dB (reference). Sometimes it's volume, but other times it's harshness at higher levels that ruins reference levels. It's hard to tell what they're doing sometimes as some studios remix for home theaters while others (Paramount?) keep their cinema mixes the same at home. I prefer the latter (and oddly the Indiana Jones movies are all Paramount and scale to reference just fine). One example is the Matrix. The home version doesn't have anywhere near the dynamic sound effect levels of the cinema version (DTS original soundtrack from a cinema DTS disc). Disney tones them down even more. You can turn The Matrix Atmos/Dolby home version up, but your dialog goes up with it too. There is no way to maintain louder sound effects without cranking the dialog to extremely loud levels. I really wish the the studios would offer cinema soundtracks as an option. With all those foreign language soundtracks they include for the wrong markets, they could easily offer both cinema and home versions of the soundtracks on the same disc....

Thanks for the inputs guys, looks like it could be a case by case scenario after all. I definitely have more Atmos discs than DTS X so it would be impossible for me to tell.

An interesting article at Forbes - Xbox And Windows Gaming Has Evolved: DTS Reveals All About Its Game-Changing New Tech - they talk mainly about the new DTS Sound Unbound that will bing DTS:X and DTS Headphone:X support first to Windows 10 PC's, then to the Xbox, followed by further home theater integration.

Quote:
In terms of object support, DTS Sound Unbound supports 32 dynamic and 16 static objects (8.1.4.4) concurrently on both PC and Xbox. ......Object-based, or spatial audio, allows sounds to come from anywhere in a sphere so sounds can come from Above, Below, or Close to you. I call it ‘The ABC of spatial sound.’ This ability to place sound anywhere more closely mimics reality, and so can increase engagement and precision in a game.
What layout is 8.1.4.4? The eighth bed speaker can be the Center Height, but the additional 4?
Below speakers?
Close speakers?

Some more informations:

Microsoft Spatial Sound
Quote:
Windows Sonic is Microsoft’s platform-level solution for spatial sound support on Xbox and Windows, enabling both surround and elevation (above or below the listener) audio cues. Spatial sound can be leveraged by Windows desktop (Win32) apps as well as Universal Windows Platform (UWP) apps on both Windows and Xbox One. The spatial sound APIs allow developers to create audio objects that emit audio from positions in 3D space. Dynamic audio objects allow you to emit audio from an arbitrary position in space, which can change over time. You can also specify that audio objects emit sound from one of 17 pre-defined static channels (8.1.4.4) that can represent real or virtualized speakers. The actual output format is selected by the user, and can be abstracted from Windows Sonic implementations; audio will be presented to existing speakers, headphones, and home theater receivers without needing any code or content changes. The platform fully supports real-time Dolby Atmos encoding for both HDMI and stereo headphone output, as well as Windows Sonic for Headphones encoding for stereo headphones. Finally, Windows Sonic apps abide by the system mixing policy, and their audio will also be mixed with non-spatially aware apps. Windows Sonic support is also integrated into Media Foundation; apps that use media foundation can successfully play Dolby Atmos content with no additional implementation.

Spatial sound with Windows Sonic supports TVs, home theaters, and sound bars that support Dolby Atmos. Spatial sound can also be used with any pair of headphones the consumer may own, with audio rendered by the platform using Windows Sonic for Headphones or Dolby Atmos for Headphones.
It seems a lot like Sony's 360 Reality Audio - an arbitrary layout with virtual speakers below and above if the physical speakers are missing.

The eighth floor speaker might be Centre Rear. The DTS:X speaker layout has 3 Below speakers (not 4) but no "Close" speakers. Since they're talking about headphone virtualization, the speakers could be at any virtual location and might not follow the DTS:X speaker layout that we are used to.
