so to playback the Hi-Res 5.1 from a DVDA in Foobar, do you just drag over the AUDIO_TS file and copy it to your hard drive? and away you go..?!?

The AUDIO_TS file is the Dolby Digital layer NOT the DVD-A MLP. If you want to rip encrypted DVD-A files, there is a lengthy procedure requiring a few programs at least one of which is no longer available as they were forced to remove the DVD-A capability and then you take the MLP and strip the 6 HI-REZ wav files. I forget the program it is on my old DVD-A ripping laptop from years ago along with the other obscure programs. But SACD I have not been able to do other than taking the individual analogue outs to a cd recorder then making an MLP with Surcode and burning them to DVD-A
 
The AUDIO_TS file is the Dolby Digital layer NOT the DVD-A MLP

AUDIO_TS actually a directory on the disc, with lossless streams, either stereo or surround or both.
all of the rest of stuff, such like HiRez (PCM 96/24) or 48KHz stereo, lossy surround, video streams, photo gallery
located in VIDEO_TS directory.
lossless HiRes are the files with extension .AOB in AUDIO_TS and yes, can be directly played or extracted
to HDD by foobar. doesn't need anything else.
 
FYI - I've used foobar2000 to do the things listed above, and used it as a upnp/DLNA renderer to my Oppo 83SE. But - I could not get it to play full hi-rez 5.1 streams in 96/24 on my Oppo - I had to decode to PCM with a bit depth of 16 bit... if I went to 24 bit it didn't work :(. Anyone got this Working on a Oppo 83 (or 93)?

As a player in itself it seems to work well.

Also (as stated above) really useful for:
  • converting to wav from PS3 ripped SACD-Rs... (I've made some compliations with sacd & dvd-A tracks via this method)
  • ripping MLP from DVD-Audio (I usually use DVDA Explorer though)..
  • removing DVD-A watermarks

Back on topic - Can't wait to hear ELP & Tarkus (if they ever get released this year!!!!)
 
yeap, in any configuration - mono, stereo, 4.0, 5.1, as separate tracks or merged to single, .wav, flac, aac, etc.
as i said above - it's very flexible and works through those donated add-ons.




you may use physical disc, ripp AUDIO_TS folder to HDD, ripp DVDA to .iso, extract and save MLP streams from disc to HDD...
in any case foobar will plays.

perhaps we went too far off topic.

i discovered there is a Mac equivalent to Foobar, called "Decibel" (formerly "ayre wave" apparently) but it won't do a thing with either the Audio_TS files on a DVDA disc, or the files after you've ripped them to your hard drive. or at least i couldn't make it work!

maybe time to get "Parallels" for Mac and run Foobar 2000 in an emulated situ..!?
 
that's right, die drei K - Kinder, Kuche, Kirche :)
how's your conversions progresses?
i hope stove not yet involved :)

perhaps Jon or any other moderator should move all this stuff about foobar and mac adaptation to separate topic.

I feel bad for steering off topic but when the flow of Convo heads that way, as I have no other people to ask about how to convert/Foobar with DVDA, etc apart from you QQ guys, I leap on these (off) topics as I'm desperate to legitimately back up my DVDAs (and SACDs but I realise that's a whole different ball game).

I am still wondering if this Foobar can actually rip the DVD-A tracks to 6 individual wav files. The way I have done it over the years is labor intensive to say the least. Being able to play a DVD-A disc with Foobar and making a copy of the disc is not important as I can do that. And doing the same fro SACD would be my final goal!
 
Mr. Wilkes:

You may have misunderstood my post of July 8th in this thread.

I respect your position as a member of the profession. I also greatly appreciate that you are continuing to work towards getting more surround sound music released. There are far too few people in the music business that seem to care about what I see as the ultimate recorded musical art form. I thank you for those efforts.

I have been collecting surround sound music since I was in my teens, when quad started it all. I had a JVC DVDA player when the format was less than 3 months old. I had a Sony SACD player as soon as I could buy one. I am the quintessential early adapter. In my life, I have spent at least 80% of my disposable income on this hobby.

In your reply you said
to blame it all on the end users not wanting bonus content is pure bollocks.

I agree... that would be bullocks!

For the record, when DVDA first came out, I saw plenty of reviews of hardware in the A/V press that cast a negative light on the use of menus on what the reviewers saw as a high resolution audio format, not a DVD. This was often cited as a reason for the preference by the reviewer for SACD as a format. I didn't agree with much of the reviewers' often politically motivated positions, but this may have been a factor that hurt the success of DVDA.

Actually, I have personally owned a few DVDA discs which were either poorly authored, or did not work with the firmware of my specific DVDA player. These discs did not default to play, nor did they go to the top menu. In fact, without a monitor attached, in some cases I could not play a disc because I had to be able to see the menu items to get to play, which was not always the top selection in the top menu. Also, with some discs, there are various streams with stereo, 5.1 compressed, and 5.1 uncompressed tracks. Without a monitor attached to see where these selections are on the menu, you sometimes can only get the stereo stream. For me, personally, I didn't care. I always have had a monitor attached, so it was not a problem.

Ultimately, had the labels and hardware companies agreed on one format and marketed it properly, as they did with compact disc, we might have seen a different result.

I look forward to the ELP releases on August 14th. I'll be buying them both. I can now even enjoy them a bit more knowing I've had the pleasure to converse through this forum with the engineer who authored the discs.

Then that was down to the reviewer - DVD-A is definitely DVD.....and again it seems that we have a case of "damned if you do & damned if you don't" when it comes to onscreen menus etc. I don't see any other way of doing these so that things are easily accessible unless the content is solely one album, with absolutely no value added content (aka bonus material) at all. We'd certainly never have got the King Crimson or Porcupine Tree titles on SACD as it's not possible to put that much content on the disc, and video is simply not an option at all.
Of all the "reasons" given as to why SACD was "better" by some reviewers the one that still makes my blood boil is the "you must have special hardware to play these" one, as if you don't need specialist hardware for DSD playback. But I digress.....

Whilst I see your point here, what would you propose as an alternative? The only options we have available as authors here is to start playback of title domain or Audio Manager domain (album or menu system). We've experimented with autoplay of title domain (PT's "Stupid Dream" works in this manner) and it has irritated some people, pleased others & the vast majority don't seem to care either way. I'll put my proposal at the end of this....but I agree with you - there are some pretty poor efforts out there, as well as some superbly thought out ones. One of the reasons (I think) for the variations is that a lot of the screen designs are made by graphic designers who are thinking computers & mouseover access and have no idea what you can & more importantly cannot do with hardware players, leaving poor saps like me to try & make it work somehow.

Glad to hear it - you'll not be disappointed with the quality, I can assure you of that. Thanks also need to go to Steven for the work he has done, and for talking Sony into taking this leap of faith & trusting him when he said we could get the job done for them. It's almost impossible to understate what (to quote Steven) is such a huge leap of faith on their part.

As far as standardization goes, it will be close to impossible as everyone does these things in a different way. That being said, we try to get as close as possible and the way these discs have been set up is so that the initial splash screen goes to the main title page and will never be seen again and the default selected button is PLAY.
Audio_TS is defaulted to the 5.1 stream, Video_TS is defaulted to the stereo stream (I figured most surround heads will likely as not have DVD-A access set to 5.1, and the bulk of people using the Video_TS will probably be after the high res stereo streams - plus it's not a great plan to default playback to DTS either.
To my way of thinking, I'd love to see BD-Audio take off but the costs are still prohibitive and the player penetration is still a heck of a lot smaller than DVD.
There are well over 500,000,000 DVD players out there, all of which can play this disc in at least High Res stereo mode.
If we count PS3 sales as "BD Players" (even though 95% of them are being used exclusively as games consoles) we have around 15,000,000 out there.
So the labels have options as follows:
1 - BD-Audio type discs as standalone discs.
Pros - prime content only available on BD might drive sales.
Cons - Only available on BD will almost certainly cost lost sales, as not everyone has a BD player. No CD content. No in-car players. expensive to produce & replicate
2 - DVD-A type discs as standalone discs
Pros - same audio quality as BD in general (nobody is really doing 7.1 or 24/192 5.1)
Cons - requiring an audio-capable player to access content will cost lost sales (same argument as against BD standalone). No CD content
3 - DVD-AV/BD double pack.
Pros - everyone is happy
Cons - price (expensive to produce, expensive to replicate). No CD content. DVD must be a DVDA or in-car players will struggle a lot of the time.
4 - CD/DVD-AV double pack
Pros - everyone's a winner.
Cons - limited to SD video, but most BD "bonus" video is usually SD anyway. (concert titles are another matter altogether and should always be DVD/BD packs).

The trick, which was ignored completely by the nay-sayers 10 years ago, is to make sure you also put a decent Video_TS title set in there as well as the Audio_TS.
and by decent, I mean LPCM stereo & DTS 5.1, leaving Dolby Digital well out of the whole picture as it has no place in a music title. Such a disc is universal, and moreover gives you the exact same quality as BD.

SACD for me is a non starter. It's again expensive to produce (although relatively easy to put together), and you are limited heavily in terms of content. Putting the same content we crammed onto some of the Crimson titles would have taken 4 or 5 SACD discs to duplicate.
 
https://www.quadraphonicquad.com/fo...n-5-1-Surround&p=155332&viewfull=1#post155332

you have put it very nicely and detailed. one thing i cannot agree is a first play/splash which in fact quite annoying thing.
why do not build DVDA without it? or it is mandatory?

+1

Personally, I can't stand that audio blurb that plays at the start of every Crimson disc. Even if it came straight from Fripp himself, it's super annoying.

Would also prefer that when playing the disc the extra tracks follow in sequence without having to go back to some menu to play them, the idea being hitting play ONCE and hearing everything on the disc in sequence.

Great post
Thanks for your insight.
 
totally agree with you, Neil..! I've heard that garbage too many times about the need for extra hardware for DVDA!

I can't think of one hybrid SACD I own (still modest by a lot of QQ-ers & SA-CD.net-ers' standards.. tho' i've over 100 rock & pop SACDs now) where the redbook layer is any good.. and then there's the single layer discs.. what can you do with them without an SACD player!?

Plus, at least with DVDA you can enjoy surround in some form on ANY DVD player and we all have one of those!

Without an SACD-capable player, SACDs (whether hybrid or not, the redbooks so shoddily mastered every time!) are pretty much useless and the argument against DVDA is, imo, totally void!
 
Back to Mono is also the title of Phil Spector's box set.

His next box set will be titled Back to Jail.

His version of Nutrocker is more authentic than ELP's!!

My old DVD-Audio player I had in my cars autoplayed all DVD-A discs while my newer DVD-A players in my cars have a video screen and I have to select from the on-screen menu to start play. And isn't there a menu in some home players that can be set to autoplay?
 
My old DVD-Audio player I had in my cars autoplayed all DVD-A discs while my newer DVD-A players in my cars have a video screen and I have to select from the on-screen menu to start play.

Probably because in-car players use the SAMG component of a DVD-A (Simple Audio ManaGer) as opposed to the regular AMGM_DOM menu system (Audio ManaGer Menu Domain). Only simple (ie, "non smart") players use this - all players capable of outputting video, or Universal players, will never use the SAMG file (Audio_PP.IFO) and as a result, such players will output just the audio in a similar manner to CD.
The other problem with AutoPlay is how do you set up the defaults - stereo or surround? If you default to surround, then unless there is a downmix also encoded into the 5.1 then anyone with a stereo only system will just get L/R, or a so-called S.M.A.R.T. downmix (if the player even supports this) instead of the intended 5.1 mix. Okay, it is also possible to author in PGC Block mode (which is how we do them) but again, something needs to be set as the primary stream in the group (PGC Block authoring uses a single group for both surround & stereo streams, enabling them to share ASV and ASVU assets) or you will always run the risk of the disc not outputting what you expect.
This is why we create ours to default to 5.1, and as soon as the Root Menu appears you can just hit PLAY and get the 5.1 mix of Group 1.

And isn't there a menu in some home players that can be set to autoplay?

Depends on the firmware in the player, and this can never be predicted. All players vary, and some vary wildly.


An earlier reply said it would be preferable for all content to play through, one group after the other - this is not possible because of the grouping system. Once a group is entered in playback, it will play through until the end of that group after which it will always return to the top menu. You can set "traps" in the Pre-Command area of the top menu to make it fall through to the menu that called the last tracks you played though by assigning a GPRM to each section. I've not yet worked out any way to play all content, one group after another, without interruptions - it is probably possible but would be compex to encode.

This is getting wildly off-topic - I think it should maybe get pruned & all non-relevant posts transferred to the DVD-A authoring forum, maybe?
 
Another thought to toss out there for speculation - Pictures At An Exhibition. We think of that album of being that piece of music (plus Nutrocker of course) but it's a live show. If they've got the multis for a 5.1 mix will the bonus tracks be the rest of the concert? Yes, we've seen and heard the dvd PaaE but that's a different concert...getting the rest of this particular show could be awesome!

This 5.1 thing has me going. Why does everyone refer to DVD-Audio as 5.1? As I understand it, the ".1" is any sub frequencies sent to the subwoofer by your sound processor. A DVD-Audio disc has SIX distinct channels with the Sub/LFE being the sixth channel...at least that is the way I have understood it. So 5.1 and DVD-A are not the same thing...am I wrong there Neil? It just makes me wonder why anyone calls DVD-A 5.1. Anyone else have input on this?

Well, I can send that .1 to my subs and mains if I want, so it is not a distinct channel IMO. I actually prefer 4.0, and then I can still send the low bass signals to my mains and subs. The center channel is valuable in the right hands (like Steven Wilson) or more often than not does more harm than good (again IMO).
