How to grab DVD-Audio? Options

[grug]

Question: PPCMripper says it won't extract multichannel audio, that the disc must be decrypted first.  Could anyone describe how to get the multichannel audio from these discs?

What I did was rip the video portion of my disc with DVD Decrypter, rip the DVD-Audio portion with dvdaripper.exe, made an ISO out of it, and mounted it.

Since the "disc" is protection free PPCMripper should have no problems.

[unfortunateson]

But DVDaripper changes the large AOBs to tracks of MLP files, and WinDVD only can playback AOBs through IFO files, so how exactly does it work?

[grug]

I don't know what you were doing with DVDAripper, but I ended up with a directory full of unprotected AOBs.

DVDAExplorer is what changes them to MLPs.

[unfortunateson]

Oops, sorry for the mixup.

I don't believe this DVD-A im trying to rip is CPPM protected, there is no DVDAUDIO.MKB in the Audio_TS directory, and the few tries I've done with dvdaripper have been unsuccessful, but ppcmripper rips 2ch waves just fine.

Next Question...

When you convert a Multichannel wav file to Nero AAC using foobar and foo_nero, does it have the correct channel order?

Edit: On another note, I just went to three different music stores. None stock DVD-Audio or SACD. I guess that says alot about the long term future of these formats.

[grug]

I´ve read that the Creative Audigy 4 supports DVD-A up to 192KHz -> so there will be no need to remove the creativeDVD-A driver as adviced, am I right? 

No, you'll probably have to. The Audigy 4 and Audigy 2 ZS are identical except for the DACs.

I was able to rip an entire retail DVD-Audio to 5.1 WAV and transcode them to FLAC. Metallica - Metallica (Black Album) if anyone was wondering which album.

Edit: Here is a grab from Audition of Enter Sandman...



And here is Sad But True...

Here's a Slashdot comment linking to this thread. I had to link back to it. It was just too priceless. Yay for massive recursive linkfesting.

Oh bugger

EDIT: That was my post on slashdot btw...

So, what are folks using to burn the AUDIO_TS directory?

Above, someone made an ISO with the VIDEO_TS and AUDIO_TS directory; I know Nero doesn't recognize AUDIO_TS -- is there anything that anyone else has been successful with besides Gear Pro?

Anyhoo:

I'm starting to wonder about watermarks. I wonder what'll happen if I re-watermark the watermarked audio. (I do have access to the Verance embedder.) This may cause an audible change, though I don't think we're going to be able to get rid of the watermark without screwing with the audio. The whole Verance thing is unfortunate.

At least for stereo 24/96, what you can do is create an LPCM DVD-V; most modern DVD-V players support this, and it sounds quite nice. (Even 192/24 'half sampled'). The watermark muting doesn't seem to engage: YMMV. (Even if your DVD-V player has a 192/24 dac -- some do now -- I believe the 192/24 LPCM rate is above the maximum data rate for the DVD-V spec anyways.)

Anyone have any other ideas about playback methods or venues? I could certainly see, after Creative releases their x.Fi, or using one of the other 192/24 cards on the market, you could make one hell of a high rez 'hard drive music server' out of a stack of DVD-A's.

Of course, that is, if 1) they keep producing DVD-A's after this and 2) any new versions of WinDVD become compromised and the big one 3)if the Recording Industry doesn't come down on InterVideo with the force of five thousand gods and the fire of a million suns.

I believe that #3 will occur, and it'll be so loud and violent you'll be able to hear it from space.

I actually used Gear Pro Mastering Edition, and saved the disc to HD. Mounted the .DV1 file using Daemon Tools and ripped from there using PPCMRipper.

seanyseansean: If you linked to RW directly, you would have had my design slashdotted (and Dibroms CSS goodness of course), that would have been cool.

Well, it's still up. Fantastic!

Haha. So here is the HomeBoy guy. Hello, IceDragon.

I'm starting to wonder about watermarks.  I wonder what'll happen if I re-watermark the watermarked audio. (I do have access to the Verance embedder.) This may cause an audible change, though I don't think we're going to be able to get rid of the watermark without screwing with the audio. The whole Verance thing is unfortunate.

The dude that proposed that I host these tools at RW told me he can actually hear the watermark clumps in the middle of the music. So, if you rewatermark them, it's likely you'll only make quality worse :-P

At least for stereo 24/96, what you can do is create an LPCM DVD-V; most modern DVD-V players support this, and it sounds quite nice. (Even 192/24 'half sampled').  The watermark muting doesn't seem to engage: YMMV. (Even if your DVD-V player has a 192/24 dac -- some do now -- I believe the 192/24 LPCM rate is above the maximum data rate for the DVD-V spec anyways.)

Yes, that's indeed a good idea. I'm pretty sure DVD-V players can't detect Verance watermarking. (maybe DVD-a/DVD-v hybrids can?)

Of course, that is, if 1) they keep producing DVD-A's after this

Thei invested millions of dollars on DVD-A already. It would be easier and cheaper to make an scapegoat out of me and skin me alive.

2) any new versions of WinDVD become compromised and the big one

Even if Intervideo makes their player unpatcheable, you can always count on old versions. The only risk is that discs being pressed from now on might refuse WinDVD's decrypting key.

3)if the Recording Industry doesn't come down on InterVideo with the force of five thousand gods and the fire of a million suns.

Unlikely. What's Intervideo's fault if some russian hacker (always russians! These guys rock) managed to reverse engineer parts of their code? It's not like encrypting their code would be of much help if the guy is a professional hacker (and, considering the stunt he pulled, I would suppose he is)

I believe that #3 will occur, and it'll be so loud and violent you'll be able to hear it from space.

I don't know... I can't see why IV must be punished because of this whole mess. And I don't see how could they have avoided it either.

Several articles are linking directly to RareWares. No worries, man

Excellent, lets distribute these from our free countries.

Hehe. Well, I'm not confident on brazilian freedom that much these days. Standing up against Dolby regarding patents is one thing. Standing up against the RIAA regarding copy protection circumvention is another one, and much more serious.

If I receive a C&D letter, I'll immediately comply and take the binaries down. After all, I have nothing to gain being stubborn, and the files have been spread enough by now...

Identifying the exact timing and location of these would be ... interesting. For one, to hear it. For another, to see what we could do with them.

Hmm. Any chance of any further/newer versions before that happens?

I'm not the developer, dude. Let's wait and see if he gifts us with another version soon.

[Sgt_Strider]

So let me guess, the only way to rip this is to have a Audigy 2 card?

Nope, the soundcard is irrelevant.

[icedragon]

Working on this now. I have to run the Verance embedder in VMWare, since it actually is from a few years ago, and only likes to function under NT4, so it's kind of a bitch. But the first step here is to subtract watermarked audio from its original PCM, and see if we can find some sort of pattern.

The embedder has about five levels from weak to strong, so am starting at strong; not sure if this alters frequency or actual 'convolution', or what.

I'm not the developer, dude. Let's wait and see if he gifts us with another version soon.

I know you aren't Wise too, to make that very clear
