    Came across this article on the bbc.


    This is the best part:



    Seems like another effort on making some money off placebo.

    This?
     
     
    I guess they could start by stopping the loudness war and producing tracks that are more than just mush and walls of noise. After that they could sell all albums as FLACs/ALACs digitally. This has to be cheaper than the CDs.
     
    Once that is achieved they can start trying to sell the more expensive "high-res" stuff.

    Again, I feel it totally depends on the mastering.  I've got the 2011 Dark Side Of The Moon on Blu Ray audio with the Immersion Set.  I still think my Black Triangle CD sounds better for the stereo mix.  
     
    It just proves to me, time and time again, that CD is perfectly capable of excellent sound quality if the mastering is done properly.

    Well, one interesting observation was that the masters for some of these releases are the analog recordings.
    So I'm not sure how many bits of resolution is actually possible.
    If they're just up sampling or doing some conversion then whats the point.

    There is the advantage of multichannel sound. SACD is a pretty niche product. DVD and Blu-Ray have much better penetration into the market. The only problem is that most people with 5:1 systems haven't fine tuned them for music playback. They goose things for the boom boom bass of modern special effects movies. My system is 5:1 and is set up for music first and foremost, but I think I am the exception, not the rule.

    Also depends on what 5.1 setup are we talking about. Most off the shelf 5.1 are 'home theater' systems.

    Which is a shame, because 5:1 for music is as big an improvement over stereo as stereo was over mono.

    I wonder how many of these Blu-ray releases will be in 5.1? A man can only dream, I guess.
     
    I'm assuming this will be similar to some 24-bit releases - Maybe a re-master, with a little more dynamic range for analytical listening, and less studio-compression than the originals?

    Well, I doubt whether re-mastering can add some dynamic range.
     
    Compression yes, but AFAIK, there's no need to do any processing of any kind. Just issue the master's digital copy, there should be plenty of space on these discs.

    If it isn't 5:1, there isn't much point.

    And 5:1 audio is like video 3D. For effects, ok,. For main delivery of music, wonky. If the material was designed with 5 main channels in mind, it might have some value but this re-mixing of existing material has been a failure for all but the minority.

    http://en.wikipedia.org/wiki/Timeline_of_audio_formats

    There are more than a few people who still insist a technology invented in 1948 is better than the best offered today.

    The only material that can benefit from new formats would be new capture. Working with the material that has already been captured will only be as good as it's format. Since the majority of desired material was made during the analog age, it is what it is and that is mostly tape.

    IMO, format advancement is an industry trying to reinvent itself to convince the buyer it's a rewarding effort worth spending a buttload of money on. I've bought enough copies of Dark Side of the Moon to say, no no no. But new material is a different animal. Just not very much of it is to my taste.

    That ain't so. I have a decidedly non-wonky 5:1 system. It's more work to set up properly, but the improvement of multichannel over stereo is as great as stereo over mono.
     
    Also, DSPs make even 2 channel audio sound much, much better with a clearer, more dimensional soundstage.

    Maybe I'm missing something, but 5.1 puts two speakers behind the listener right? That would feel like sitting in the centre of a performance.
    Is that the intended goal?

    No. The center channel allows you to separate the front for a wider soundstage, and the rears mesh with the mains to create an ambience that pulls the front soundstage toward the listening position a bit, giving it depth and a slight ambience in the rear that creates the feeling of a larger room. It's a phase thing. The room isn't dead behind you. If fills in just enough to feel present, but not enough to shift the front stage.
     
    My Yamaha AV receiver has a 7:1 Stereo DSP that takes stereo recordings and maintains the front stage and stereo placement, but opens it out to fill the room. Hard to describe, but if you cup your hands behind your ears while you listen to two channel, you'll sort of get the idea.
     
    When you switch from mono to stereo on a 2 channel system the stage stays the same, but the phase fills in and opens it up. It's like that except all around you.
