I recently asked a few questions on the SACD forum, and need a little info on DVD-A. Are there DVD-A 2 channel stereo mix on a DVD-A ? I'm just trying to figure which way to go on a DVD player, especially since I may be staying with my 2 channel setup for now. I know all SACD's have a 2 channel stereo mix, and wondered about DVD-A. Trying to figure if a universal player maybe the way to go, and have both formats and video, even if I only stay 2 channel for now ?
Follow Ups:
Actually, DVD-A started out emphasizing 5-channel but some labels are starting to pay attention to the quality of the 2-channel mixes (in contrast, SACD started out emphasizing 2-channel and relatively recently opted for increased emphasis on multichannel). At the moment, it appears to me there is not enough "quality" 2-channel DVD-A software to warrant DVD-A adoption solely on the basis of 2-channel music, YMMV.OTOH, I have heard some good stuff on multichannel (e.g. DSOTM) so I see some value to having a MC setup. Still my adoption of DVD-A at the moment depends on "piggyback" onto a DVD-V upgrade. This could change if the DVD-A/CD hybrids actually pan out and the major labels push the format as a result. Unfortunately, I HATE the idea of "flipper" discs but this may not stop the major labels...
you can fit in a DVD-A disc, and more if you use MLP
If you are using dual layer discs, that number goes up of courseBest
1) Most do at the moment
2) Many may not in the future if the format catches onDVD-A is focussed soley on a 5.1 future, since people with DVD's will normally be hooked up to a hometheatre system.
What's wrong with you?You should refrain from posting these "Accurate" and "Unbiased" answers, you obviously don't understand jack about this.
DVD-A allows for 2CH, and any combination of multi-channel (3, 4, 5, and 5.1). Stereo 2CH is available as long as publishers include a stereo section on their titles. It's also the only way to get the full 24/192kHz stereo.
So, Yes, DVD-A allows stereo, except for one publisher (Silverline), which probably doesn't own the rights to the stereo version of the titles they publish. And Yes, a universal player will work with a stereo system. The issues are exactly the same with SACD. The only difference is that on a DVD-A title, if you play on purpose the 5.1 version, your player may downmix the track to stereo, but you can also listen to the front 2 channels of your 5.1 mix if you want to.
And No, DVD-A is not "focused" on anything, it's not "aiming" at anything, it doesn't do anything, it has no life of its own.
DVD-A is an authoring format designed to enable authoring audio content on a DVD, with the widest possible format compatibility, including legacy CD at 16/44.1 all the way to high resolution 24/192.
Only publishers and their marketing people are "focused" on specific formats for their releases. Whether they decide to go MCH only is pure speculation at this point.
Do some homework.
YES or NO Eric...... you posted half a page of nonsense and avoid the question again.
Read the original post, and you will see that the question was not whether a stereo track is mandatory in the DVD-A specs.
The answer provided by Oscar was factually correct and comprehensive enough, I think.The response to your own personal question was in my post: No, it is left to the publisher to decide what version he wants to publish (and perhaps, which version he has the rights to publish). There are mandatory specs and others are optional in the DVD-A specs, as you could see in the post from Minnetonka yeterday. I think there were additional recommendations or guidelines regarding stereo tracks, but I'm not sure.
Since you know there are DVD-A titles available in MCH only and downmix stereo, I wonder why you ask that question.
Best
I have no confidence that stereo mixes will be kept if DVD-A becomes a mainstream format.

Hi Wayne,DVD-A often has a 2C mix in addition to a MC mix. On older disks these are 'groups' that you need to be able to switch to the group you want. The player will make that easier or more difficult – sometimes to the requirement of viewing a connected screen to change the group through the menus. For the players, I can only speak to the Meridian 598 which makes it easy. Unfortunately, most disks will default to MC – an annoyance to me.
All MC disks should be able to downmix into 2C. This, I believe, is configurable within the player (such as the Meridian 598) but maybe someone else with more experience with other setups will answer. The downmix of MC into 2C is not as good as the pure 2C mix to my ear.
Finally, the DVD-A recording standard (?) is suppose to be changing from using the groups. What this means is that you will be able to change from MC to 2C using the ‘Audio’ button on the player. This is the same as when viewing movies with multiple audio tracks where you can toggle through them.
A very nice DVD-A site:

A multi-format machine would be desirable as the material available on each format is different. You may want to sample material in each format to see if the 'format war' applies to you (don't like one of the formats). Multi-format players will likely have a compromise in one of the formats (CD, SACD, DVD-A, DVD-V) so research and listening will be in order.
BTW. I enjoy both DVDA and SACD equally. Both sound great, sometimes, and bad others..
I just wish that there had been a 384/24 spec. heh.
> > I just wish that there had been a 384/24 spec. heh. < <Did you mean 384kHz/32bit? That sort of spec is mainly of real benefit only within the recording chain itself (i.e. during mixing & DSP processing) to minimise any mathematical errors so there is insignificant signal degradation to the final 24bit output which the consumer hears.
but it didn't happen with the DVD forum?
Samsung suggested 24/384 instead of 24/192. I wish the DVD forum would have took them up on this. I also wish they would have adopted "no watermarks" as well. Oh the mistakes they have made. Would have, could have, should have...
There are some who believe that 58kHz/20-bit is enough to attain audible transparency. I'll let one of them explain:http://www.meridian-audio.com/w_paper/Coding2.PDF
There is some justification for 96kHz but beyond is more likely marketing then need.
Rdh,Sort of.
The paper defines the MINIMUM requirements for delivery of high quality audio to the end user.
Utilization of higher sampling depths and rates is encouraged to allow for any and all required processing without compromising the quality of the delivered channel to the end user.
The point to be made is that increasing the sample rate beyond 96kHz (to answer the threads question of a 384kHz standard) seems to be more of a marketing feature then a requirement of the delivery mechanism for the consumer.From the same paper we have the quote:
"Although there is a small lobby that suggests even higher sample rates should be used – like 192kHz– the author disputes this; preferring to point out that when 96kHz channels have been correctly designed in terms of transmission, filtering, etc, that higher rates simply will not offer any benefit."(So maybe Robert Stuart doesn't know what he is talking about but both you & I seem to enjoy some of the products he has a hand in.)
I would rather see the existing standard be used to create recordings for me to use. As the standard does allow for 192kHz we appear to have enough headroom already.
Working with higher resolutions while in the process of creating the consumer product does make sense.
You reach a point where the diminishing returns become essentially nil, and IMO, it's somewhere between 96 and 192K.Then again, Meridian puts their money where their mouth is, since they are 24/96K enabled across their entire product line, nothing higher for the present.
There is also a practical issue that 96ks is exactly twice the sample rate of 48kHz which is used in many DVD Video and many recording studio's.
