Dolby’s modern codecs are much more advanced than conveyed by simply dividing the bitrate by channel count (768kbps/11 channels ≈ 128kbps stereo).Care to Elaborate?
Ok, so still probably roughly equivalent to a 320kbps MP3 then? Still quite a difference from studio grade 48/24.Dolby’s modern codecs are much more advanced than conveyed by simply dividing the bitrate by channel count (768kbps/11 channels ≈ 128kbps stereo).
Most of the channels have little activity, and EAC-3 is smart enough to allocate its finite bitrate where it matters most. EAC-3 is a contemporary of AAC and other second generation codecs anyway, much improved from basic AC-3 and MP3 (first generation codecs).
Yes lossless is still great when available, but it is a misnomer to assume EAC-3 works like each channel has a fixed bandwidth allocation. That would suck. I’ve been able to pass compressed audio tests before, but never for moderate bitrate EAC-3, it’s pretty good.
I have compared back to back Apple streams with BluRay audio files and... perhaps its my ears, but the difference is not always apparent. Perhaps if I had some training I might be able to hear something?Ok, so still probably roughly equivalent to a 320kbps MP3 then? Still quite a difference from studio grade 48/24.
Better qualityIs there a reason to buy these Blu-Rays over streaming the Dolby Atmos mixes on Apple Music or some other streaming service?
EVERY SINGLE TIME!Better quality
I picked up Best of the Doors and Tres Hombres and found the stereo mixes to be great. For Tres Hombres it is the original version with the correct drums, not the awful redone stuff they did for the 80's CD release. The surround mixes on those are worth a listen though. Tres Hombres in quadraphonic was quite good. For clarity, the stereo mix on the blu-ray Best of the Doors is a new one by Bruce Botnick. It is very similar in dynamics to the 80's two CD release but is a different mix. I personally have no preference. Both are enjoyable and fairly similar.Tonight I ordered The Best of the Doors on Atmos and No Jacket Required on BD, and was so desperate for more that I even ordered a Quadio BD version of Tres Hombres, and I rarely care for quadrophonic mixes where each instrument has it's own channel. It's also my understanding that the original source tapes were not "available"
But I can just about guarantee that I will find them to be a superior listening experience than listening to the cd.
Stereo is nice, I listen to it a lot, but the inclusion of a center channel only makes sense, both conceptually and in real world listening
Objectively Atmos on blu ray blows away the streaming audio versions. Streaming Atmos is lossy Dolby Digital + at 768 kbits/sec whereas the blu ray disc audio is lossless at 7000 to 10,000 kbits/sec.I have compared back to back Apple streams with BluRay audio files and... perhaps its my ears, but the difference is not always apparent.

Is there a thread on here specifically for blu ray / spatial audio album releases?
I'm well aware of the stats and my MiniDSP + Genelec + Sub setup is certainly revealing.Objectively Atmos on blu ray blows away the streaming audio versions. Streaming Atmos is lossy Dolby Digital + at 768 kbits/sec whereas the blu ray disc audio is lossless at 7000 to 10,000 kbits/sec.
Whether or not you hear a difference and it matters is personal for you to decide. I had one of those free three month accounts for Apple music. I listened to some Atmos recordings and after the initial pleasure of those mixes, with concentrated critical listening, the streaming versions became tiresome for my listening, and I cancelled the subscription. By contrast, concentrated critical listening to the blu ray versions is, for me, consistently a pleasure. I have had formal music training, perhaps that makes a difference, perhaps not, but I am trained to listen critically. Superficially, the streaming versions sound okay, but after spending time I notice the loss of detail and lack of precision.
Unfortunately the selection available on blu ray is more limited, and are often released in limited editions. However, because I have found the streaming Atmos releases to be painful, other than as background music, and since I don't listen to music in the background, streaming is, for me, useless.
This Dire Straits - Brothers in Arms album. For my part, I've listened to it too much. Maybe that's why I find these from Dire Straits better these days:Hello,
More than a year ago, article titled "Blu-ray “pure” audio: a format for the future?" raised the inquiry regarding whether Blu-ray represents the future format for audio..
When is it today?
View attachment 439287
For a start, announcements of forthcoming releases are on the increase, with flagship albums such as :
Dire Straits - Brothers in Arms
Elton John and Brandi Carlile - Who Believes In Angels
Roxy Music / Avalon
Prince and the Revolution - Purple Rain
In just over a year, more and more albums have been released in Blu-ray format, featuring the Dolby Atmos track in Lossless Dolby Digital TrueHD format.
But also, by offering a stereo track without dynamic compression, as with Tears For Fears' “Songs for a Nervous Planet” or Ultravox's “Lament”, thus proposing an audiophile approach to this medium.
Also worthy of note is the superb Steven Wilson - The overview, a reference in terms of Dolby Atmos mixing.
Often in special, limited editions from SDE, or more and more widely distributed editions (Pink Floyd, The Rolling Stone…).

Just take a look at some of the titles released since June 2023 to see the diversity and the presence of some very well-known singers and bands:
- Pet Shop Boys “Nonetheless”
- With The Pineapple Thief “It Leads To This”, we realized that bluray was the most audiophile medium, offering the best audio quality.
- Pink Floyd “Animals”
- Paul Young “No Parlez”
- Mark Knopfler “One Deep River”
- John Williams "John Williams in Tokyo"
- Alphaville’s “Forever Young”
- David Gilmour “Luck and Strange”
- Steven Wilson “The Harmony Codex”
- Pink Floyd “The Dark Side Of The Moon”
- The Rolling Stones “Hackney Diamonds”
- Peter Gabriel “i/o”
- Mike Oldfield “Tubular Bells”
- Serge Gainsbourg “L’homme à tête de chou”
- The Alan Parsons Project “Pyramid”
- Ultravox “Lament “
- The Cure “Songs of A Lost World”
- Simple Minds “New Gold Dream (81–82–83–84)”
- ...
This is not the case for all albums, but the trend continues.
In parallel, there is also an alternative distribution of the Dolby Atmos track in the Lossless Dolby Digital TrueHD format, with dematerialized music sales sites such as:
https://shop.2l.no, https://immersiveaudioalbum.com, https://www.nativedsd.com
For example
The Tsuyoshi Yamamoto Trio is back with a new album, “A Shade Of Blue”.
Madeleine Peyroux - Let's Walk
The big winner is the Dolby Digital TrueHD Atmos format, and some editions also feature an uncompressed dynamic stereo track, providing the audiophile quality required for stereo and Atmos music reproduction.
We're still a long way from widespread distribution, but we can only hope that the spread of Dolby Atmos in Lossless and stereo without loudness war continues to develop, whether in physical Blu-ray or dematerialized formats.
And who knows, maybe one day a streaming service will be available with the Dolby Atmos TrueHD format. And for stereo with or without loudness war!
Enjoy listening,
Jean-François


Private Investigations has always sounded so, so good. Agree - I too have possibly heard Brothers in Arms a few too many times! Still....This Dire Straits - Brothers in Arms album. For my part, I've listened to it too much. Maybe that's why I find these from Dire Straits better these days:

probably as simple as low demand for lossless Atmos. there would be negligible difference on the overwhelming majority of consumer setups. great performing and huge 4K HDR TVs are dirt cheap now, but the audio equivalent is just not as accessible. streamers probably tell themselves the few enthusiasts who care will just buy blu rays.It’s bizarre that we can stream 4k movies at 25000 kbps and 192/24 at 9000kbps but Atmos somehow has to be compressed to allow for a reasonable bitrate.
You mean the difference is more negligible than 44.1 vs 96khz “hires” that they decided was worth the effort? Why would “Hires” ATMOS garner less interest than hires stereo? To me it would seem like a no-brainer for tidal to pursue in an attempt to differentiate from apple. Maybe in cooperation with ROON.probably as simple as low demand for lossless Atmos. there would be negligible difference on the overwhelming majority of consumer setups. great performing and huge 4K HDR TVs are dirt cheap now, but the audio equivalent is just not as accessible. streamers probably tell themselves the few enthusiasts who care will just buy blu rays.
got me there, audio marketing is good at upselling. wonder then if the TrueHD license is prohibitively expensive?You mean the difference is more negligible than 44.1 vs 96khz “hires” that they decided was worth the effort? Why would “Hires” ATMOS garner less interest than hires stereo?
Yes it is completely different. As the aphorism goes, you are mixing up apples with oranges. Sample rate refers to frequency response, so that a 96kHz sample rate has a frequency response up to 48kHz, whereas a 44.1 kHz sample frequency response is limited to 22.5 kHz; which is fine because human beings cannot hear anything between around 20 kHz (or lower as you age) and 48 kHz, (therefore irrelevant unless you are producing music for bats or dogs). Thus, high sample rate files are a marketing gimmick more than anything else.You mean the difference is more negligible than 44.1 vs 96khz “hires” that they decided was worth the effort?
