Converting DVD-A to MP3
Dec 24, 2003 at 7:09 PM Post #3 of 15
AFAIK you can rip the Dolby Digital or DTS tracks as with normal DVD-Video. However, there is currently no way to rip the Advanced Resolution DVD-Audio (.AOB files). These are protected with CPPM (not CSS) which has not (yet) been cracked.

I don't know if it's kosher to discuss this sort of stuff here, but you can grab the LPCM tracks from the DVD-Video side (with whatever program) and convert that to MP3.

Why!!!!!
Why would you want to turn perfectly good high-res music into low res noise. TO each his own I guess.

Agreed but it sure would be nice to be able to make backups.

I think you could go analog and connect the audio outs of the player to the pc soundard, do a line-in recording and either convert the wav files to audio cd or MP3. Of course, you wont get the same "quality", but keep in mind that you are degrading a high-res format into wavm which is pretty much okay, and then to MP3, which is not so good. In any case, using a high bitrate should give you results that could not be easily discernible from the original in normal quality equiptment.

Because I enjoy music and I don't spend my entire life sitting in front of my home stereo.

I enjoy music on the go, in my car, when traveling, skiing, cycling, and even sometimes when everyone else is watching the TVs and occupying my home stereos. In these cases my mp3 players do a credible job at high bitrates reproducing most music. And without the ability to make mp3s from the DVD-As, it would force me to buy CD versions as well. Seems like this is a fairly big detractor for these digital formats. If I have to record from the line out then I might just as well buy vinyl and start with analog in the first place. One of the big draws of the CD/DVD/SACD format is convenience. Without the convenience the DVD-A and SACD loose some of their luster to me.

With respect to listening to MP3s, I for one can't tell the difference between high bitrate MP3s and CDs on my headphones when I'm on a plane or skiing or just casual listening. The music is what I'm trying to listen to, not any 4th order imperfections.

I would go further to say that in a blind test, you would have an equally difficult time telling the difference.

Backups are another good reason. But portable is an even bigger reason for me. And what portables can play DVD-A or SACD? What would Bear listen to, in his 580s, when on our walks?

Onix, thanks. I've seen this process listed before. I think I need to look at my sound cards capabilities. I have a pretty simple soundcard on my computer but I do know it's 5.1 compatable but not sure how it all works. Hope it can do recording from line in.

Seems like no one knows how to rip these to digital via software. For these companies (sony, et al) to force me to listen to this music ONLY on my large home system and/or force me to buy multiple versions seems like a very user/consumer unfriendly turn of events.

It's not possible to rip a perfect digital DVD-A because it's encrypted with CPPM. Nobody has managed to crack it (unlike CSS which was easily cracked.)

I suggest decrypting the CSS encrypted DVD-V layer (usually has LPCM audio) and converting that to MP3.

I agree ^^

What do you want to rip the high quality version for if you're just going to downsample it to 44Khz / 16 bits? If I'm not mistaken DVD-A's have to have either a PCM or Dolby Digital version which is exactly what you want, 'cos the audio engineers have already optimized the music for that format (frequency and bandwidth).

Just rip that and encode directly to MP3.

If your DVD-As don't have such a format, then you're out of luck as far as digital rips go. You can't even play DVD-As on a computer yet 'cos Sony etc refuse to let any software makers decode the MLP data (scared of piracy).

My recommendation: connect your DVD-A player to the line-in on your sound card and just record it normally. In this case you might as well let the DVD player play the highest quality it can; the sound will equate to the lowest common denominator which will be your soundcard. Record in the same frequency (44.1KHz, probably) that you intend to encode your MP3s in, so you don't have to reprocess the audio any more.

Provided you're not using some onboard piece of junk for your soundcard, the result will be quite transparent for the purposes of portable MP3s.

How about buying a $399 portable 7" DVD player and using the DD layer of the disc. Most DVD-A's come with 5 different ways of playing them, including 2 channel Dolby Digital.
Also, has anyone tried Clone Cd and just copy to CD-R. I do that with my DSD Hybrid SACD's when friends want copies.
Interesting note: I have my headphone amp (RA-1) hooked up to the tape monitor loop, and I can play all my components except what comes out of my universal player, so the theory of copy protection must come into play. If I hook the front left & right discrete outputs directly to the amp, it works fine, but then, I can't use in my speaker set-up, without an a/b switch or constant wire swapping.

There seems to be a way to extract DVD-As and SACDs digitally. Read more here.
Expensive and inconvenient but it should work.

Portable players supporting DVD-A and/or SACD can be found at dvdrhelp.com, e.g. this one.

High resolution playback of DVD-As is possible at least with Creative Audigy 2 soundcards, others might follow. The data is sent encoded/encrypted to the card, decoding is done by the card's DSP AFAIK and only analog output is enabled at high resolution, so there's no way to extract audio digitally here either until someone reverse-engineers the playback software + the DSP.

You're only copying the regular CD (16/44.1) layer, not the SACD layer. If your friends tried to play the copies in a SACD player they'd only get the CD quality playback.

I know, but usually the whole recording is made from DSD equipment, so it's sound quality is better, and then it can be used to make mp3's, which was the basis of this thread. I am not trying to make copies of SACD's which is why I said hybrid SACD's
