Any new developments in CD format?

How do you get 5 channels?
What is red book layer and dsd layer?

You are kidding right?

Red Book is what you get at 33 1/3 RPM. DSD is what you get at 45 RPM. I believe you need 78 RPM for surround, but I don't have 78 RPM.

BTW, that's a Pearl 2 on the rack.. ;-)

I can get DSD over PCM (DoP?) from SACD's via this box using an Oppo BD103 as a source.

My digital pre-amp indicates a 88.2kHz sample rate.

With DVD-A's I get 96kHz if the data is encoded at that rate. I think I might have one DVD-A or Blu-Ray Audio disc that provides 192kHz.

Of course none of this matters if the original material was recorded in 44.1kHz/16 bits which I assume much of the 80's stuff was.

I think for some of these releases in high bit rate formats it's the remastering (like what Steven Wilson does in KC, Yes and Tull) that makes most of the difference.

I only listen in stereo. That's one of the things I like about SACD's. You can set the players' default to only play stereo layer for SACD's whereas with DVD-A's you have to go into a menu at the time of playing and pick the stereo option meaning that you now need a display attached to your stereo.

Funny, I have one DVD-A disc (ELP Brain Salad Surgery) that is supposed to have a high res stereo layer on it but it does not. Must have been a mastering goof.

Ripping SACD's can be done with an Oppo 103/105 assuming that its SW wasn't updated to prevent that. You have to get the player to run some different software via its USB port, connect a PC and the PC will see the player as a drive. You then need some SW on your PC to properly format and save the resulting data. I have never done this but I do have the files needed.

To bridge the earlier portions of this thread with the latter, multichannel and hi res music has primarily moved to Blu Ray or file-only formats (online distribution). Music had been released in Atmos and probably DTS X formats. Pearl Jam put out an Atmos mix of their recent Gigaton. They also did a 5 or 7 channel remix of Temple of the Dog. Anyway, there's probably a thread on AVS Forum with a listing of immersive audio releases if you want a listing that's not exclusive to Stone Gossard's bands.
 
My question remaines unanswered...that cd disk i posted image of in the first post clearly states its recorded in 5 channels. Or 5.1 assuming plus sub. If cd player has only left and right out, how do you obtain those other three?

I do have old dolby pro-logic receiver, but that was for movies, and i never bothered with it, terrible sound quality when applied to music.

Definitely not atmos dolby, they would put that crap logo on it.

Besides, from that video posted, atmos is bs.
 
There are simultaneously two and 5.1 channel format available on the disc (and sometimes more) and you select which one you want via your player/menu. This can coexist with a red book CD layer as well. If you only have a stereo setup, even if you pick the 5.1; you'd only get the front two channels of a 5.1mix.

That's my understanding.
 
Right. From the image, the disc in question is a hybrid SACD with a redbook (CD) layer, and a second containing a 2.0 stereo and a 5.1 DSD (SACD) mix, like many others did -'many' of course being relative when it comes to SACD and DSD files. 😉

It's a pity that nobody ever utilised the redbook format's built-in 4-channel facility, but I digress.
 
SACD players have been around for quite a while. I've had my Pioneer DV-575AK DVD-video-, DVD-audio-, SACD- and CD-player for at least a decade, probably longer. I never listened to all five channels, as I wouldn't know where to put all the loudspeakers.
