Burn a DVD-AC3 Compatible CD-R

What does AC-3 have to do with DVD-Audio? DVD-Audio uses Meridian Lossless Packing, not Dolby Digital. The DVD-Audio disc may also have an AC-3 or (preferably) DTS track for backward compatibility, but the main mode is MLP.

At this point, where everyone with a computer and a CD burner are considered potential thieves, I don't think it changes the light in which anti-piracy advocates view computer users. It couldn't possibly get any worse!
Calm down, it's *only* ones and zeroes.
Whee...just another thing for the MPAA/RIAA/Government to put DRM and copy-protection type things in. Yippee, a DVD player that won't play old-style DVD-Audio, but only new-style. Without CD-R support, or backwards compatibility. I just can't wait.
ok, so when does DVD flop and movies start coming on 2 CD's, one for video and one for audio? My CD changer becomes my movie player..
I find that the easiest surround sound is a nice pair of Sennheisers.

Then we have the comment from chrisd:

Yeah, finding new ways to easily pirate software is a step in the right direction. Wrong. Getting the manufactures and owners of such technology to start believing that not all people are theives and they can allow open standards to exist to allow copying for backups, personal use such as having a copy of said music in my car player; while in my house; or at work is a step in the right direction. All this will do is piss off the RIAA/MPAA, they'll lobby for stricter laws, and we're back here again.
..There's a-dooin's a-transpirin'
I think I've been downloading DivX files with AC-3 audio well over a year now. In fact, I remember all the confusion on the 'net when AC3 audio DVDRips started floating around and people had no clue what audio codec to use.
Hey, news flash...you can also burn MPEG-2 video files to a CD, just like a DVD!
From the article:
Dolby has officially advised me that this CD-AC3 disc should not be used as a master for CD duplication or public distribution since there's no safeguards against someone playing it back in an audio CD player. But it's a great method for making one-off test mixes. I've considered added a standard audio disclaimer on track 1 that says something like "This disc contains Dolby Digital data. Do not play in a standard CD player or speaker damage can result".
Could you think of a better gift for those you don't love?

And for this the RIAA will devise the ultimate copyright solution: The Sharpie Marker.
Go to a friend's house who has an annoyingly loud car stereo that he keeps cranked at 11 all of the time booming some bass. Slip your "Phat bass remix" into his DVD player and show him the good stuff. Then say "you can keep the CD" next thing you know, he slides it into his (clarion/kenwood/eclipse whatever) car stereo that cost more than his car. And blows his eardrums with straight undecoded ac3. Just like he blows your eardrums with his bass while you are in his car.

This is way cool. I took my roomate's Dave Matthews DVD, popped it through this program, and out came a burned CD in either DTS-CD, DD5.1, or regular CD. Way cool, and perfectly legal as far as I'm concerned. I'm making a backup and/or transfering the media to a different format.

Better than that, you can burn mini-dvd's on to a CD. There are several programs that will burn the ISO DVD directory structure on to a regular CD. This comes in handy for say, when I took my roomate's NIN DVD in DTS, and extracted the DTS track, and burned that onto a dvd-cd. The DTS track is a perfect 550mb. How cool is that. Also good for burning DD5.1/THX trailers onto a CD to take to the home theater shops to test out their systems. You can get full blown

Remember that even the MPEG2 format that DVD video vobs are stored in is lossy, although at such a high bitrate that, on a good DVD, it's close to impossible to tell.
DivX and other Mpeg4 codecs may be unbearably noisy at lower levels you've seen, but when you raise the bitrate up to where a 1:30:00 movie will just fit on a CD-R, it's very nearly indistinguishable from DVD video. This goes double for animation. Many of the anime fansubs that show up on IRC and Usenet are encoded in such a way that a 200mb file is more than high enough quality to tape and share with your friends.
The next Slashdot story will be ready soon, but subscribers can beat the rush and slashdot the links early!
High quality audio is not surround sound. Nobody listens to music on a surround sound rig and expects quality. Surround sound is good for movies, where you don't need good fidelity, but most surround sound systems suck if you're trying to listen to music. Audiophiles don't like subwoofer-satellite systems (because it's a cost-saving compromise that causes lots of problems), and a high-quality surround-sound system with 5 real high-end speakers and amplifiers would be prohibitively expensive ($20,000+). Anything cheaper, and it sounds like crap, because it's low-end.
Besides, when you're at a concert, you don't sit in the middle of the stage, so the only source of sound is from the front. That would mean that there is exactly no point in recording surround-sound audio CDs. It's a marketing measure, if anything.
And to the poor shmucks who listen to music on a satellite-subwoofer combo: I hope you don't ever come near a high-end audio system. If you do, you will probably realize that your system totally sucks, and will have to replace at least two of those speakers (and probably the amp). There is quite a bit of very tangible difference. Sort of like the difference between a 128k MP3 and the real uncompressed file.
..encoding into ogg format and burning it.
Doesn't ogg support multiple channels ?
What am I missing ?
http://www.doom9.org contains lots of information and tools to work with AC3 plus DVD, MP3 etc. The tools are mainly for expert users as they are mostly commandline only. Althought some of them come with GUI wrappers, I am not sure if they are much help as they are perfect examples of GUI from hell (no offends!). They will get the job done if you are willing to commit quite a bit of time.
Of course if you don't have a good decoder/speakers don't waste your time on AC3.

Two minutes from now the crack will be out.
If you want to refer to violation of copyright law, then please call it what it is.
I've done a considerable amount of testing 5.1 formats on CD-R and DVD-R (and variations). Yes, AC3 can be WAV-padded to look like a PCM audio file and subsequently put onto a red book CD-DA disc, but I've found that most older AC3 decoders don't understand the reverse bit-order format.
On the flip side, WAV-padded DTS does work on all DTS decoders, as it was included in the format from the beginning.
Additionally, DTS is a better format because it is fixed-rate 4:1 compression, as opposed to AC3's variable 12:1.

Ok, how many DVDs do you have in your library? You own them, right? For the most part, this isn't really disputed. Those DVD have all the music associated with the movie. In effect, I'd like to argue that you own the soundtrack to that movie. So since I effectively own the music to the movie on DVD, I should be able to download it off the internet without violating any copyrights. Unless the version were vastly different from the one I already paid for on DVD (and yes, I did pay for every track used in the movie, since all that production cost is wrapped up in the price of the DVD), there is no reason why I should have to pay for a totally seperate audio CD I paid for the music and movie once, and now I have to pay just as much for only the music? How does this make sense again? Don't worry, it's just how they expect you to pay full price when you switch to a new format even though you already have the song in a previous format. Why am I paying for another licence when I should only be paying for the price of the new media itself? Because they are just as big a pirate as they claim we are.

I can't wait for iPod support of AC-3 so that I can go about wearing two pairs of headphones and looking like a total jackass. Oh, wait, I don't need my 'pod for that. Nevermind, move along, nothing to see here.

Obviously you can't get that many minutes of video on a CD with reasonable compression, but that's OK. They're a useful way of shipping little video clips and demo reels around. I want to put my own computer animation demos on them, rather than having VHS tapes duplicated in bulk.
I know, not all DVD players will play them. Anybody have a current list of which ones will?
It's called "Bondo". Have a blast... Texas Style!! Hmmm.. I gotta stop that.

If you have a CD player with a digital output, and that is connected to a surround-decoding amplifier, chances are that'll play it back just fine. I burned a CD with various bitrate AC-3 tracks mixed with DTS tracks (CD-Text too), and stuck it in my 300-disc Sony CD jukebox. The signal was piped into my Yamaha surround receiver, and played it back perfectly - even scrolled the filenames by on the CD player's display. Very cool, listening to surround sound from a standard CD player.
That got me thinking - perhaps I could encode all my CDs down to 192 Kbps 2-channel AC-3 files, and squeeze much more music onto each CD. Load up the jukebox & get 7 weeks of uninterrupted audio...
'Cept it didn't work, of course - in order to play back on a standard CD player, the compressed AC-3 file has to be padded out to ordinary redbook audio rates - it takes the same amount of disc space. Still only ~80 minutes of audio, regardless of encoding.
Never mind - I'll encode my whole MP3 collection into AC-3 files, then burn a standard DVD (with still images & a lot of music) on my nifty DVD+RW drive. I can still fit many hundreds of hours on a single disc that way. Too bad I don't have a jukebox DVD player...
And, of course, I can still rip my Luc Besson - Atlantis DVD's soundtrack onto a DTS surround CD, and replace the humble 2-channel CD soundtrack I have in the jukebox with full 5.1 audio

When I first read this argument on the FSF website, I was quite taken by it. Since then, I have learned that it is quite mistaken.
The word "piracy" has been applied to plagiarism and copyright violation for over two hundred years. Edward Gibbon uses it in this sense in his Memoirs of My Life, first published in 1796:Please allow me humbly to suggest that, when a meaning has been in common usage for hundreds years, it is the people who try to remove this meaning that are guilty of revising the English language for their own purposes.
Despite what the title says, it's not restricted to just VCD information. It has a LOT of information about damn near any DVD player out on the market now. Has a section that compares which DVD players can do what. Might be worth a look.
I'm not sure he was talking about VCD. Isn't "MiniDVD" something different? It's supposed to be DVD quality for 18 minutes or so. Where VCD is longer, but has poorer quality.
"..Will this technology usher a new type of online piracy when DVD-Audio and surround sound systems become more commonplace?" While this is only audio, it is a good step in the right direction
Yeah, new types of piracy is the 'right' direction, alright. Bet you cant wait to load up yer Gene6 ftps and hop onto irc with yer warez buddies. Too bad it wasnt video too, huh?
I don't need no instructions to know how to rock!!!!
Huh? You have a very wacked-out idea of the way computers work with sound. Let me clear this up for you: Ogg is a binary data stream. AC3 is also a binary data stream. In fact every digital audio format ever invented is a binary data stream (as in, a long string of the numbers 0 and 1 in a particular order). AC3 is encoded sound. Ogg is also encoded sound, it is just encoded in a different incompatible way. AC3 and Ogg are different ways of encoding sound into binary data streams. The difference between AC3 and Ogg is that some consumer audio equipment can decode AC3 into sounds, but no consumer audio equipment is equipped to handle Ogg (though it could be, no reason why not). You could burn Ogg onto a CD and put it into your CD player and get static out too. That just means that the CD player is misunderstanding the audio encoding.
... which is saving money for the artists by letting them distributed high-quality samples of their music on a cheap CD(-R,-RW). An average consumer can use the same method to make remixes of their Audio DVDs. As for pirates, they generally don't care that much about top quality, so anyway they won't go and buy an Audio DVD and get an MP3. If someone just released every song as a 32MHz/Mono MP3, sales would go way up because non-pirates will discover and buy what they like and pirates wouldn't bother making higher quality tracks easily available.
Besides, when you're at a concert, you don't sit in the middle of the stage, so the only source of sound is from the front.
Not everyone sits at concerts.
The first thing I thought about when reading this was setting up a 5 channel dance party. I'm not sure what you'd do for mixers and varispeed decks though. I know a bloke who's done performances on eight speakers, with the audience in the middle, but he had to write his own software for it.

So play the audio off of one drive and the video off another. Would it be hard or impossible to synch the two?
http://www.apachez.net/purpleman/dtscd.html
I have thought about how the future will handle DVD-Audio streams.
It took a while of awkward solutionds before we easily could make a copy of a DVD-Video. Merely because the encryption is lame. From what I've read the creators of DVD-Audio have learned (or adapted in Borg terms) and the encryption used in DVD-Audio disks are much heavier and thus to be able to rip the stream one would have to get the keys out of the disk much like a standalone player does because brute-forcing a DVD-audio with todays computers would take too long and the creators know it.
So I think when someone has made effort to actually read DVD Audio-discs in all it's gallore when the keys are found they will probably be published on hackers sites.
But noone can tell until we are here. Hopefully the DVD audio discs will be priced like todays music CDs and ordinary people can build a collection of original legal DVD audio discs. Who would prefer to have about two songs per CD instead everything on one disc.
I haven't tried DVD audio discs yet but I hope that they play just like a CD audio disc and not like a DVD video disk with menus and stuff like that because when I want to play music I just want to throw the disc in an listen, not fiddle around with FBI warnings, menus and stuff like that.

Most 5.1 channel mixes are done using simple pairwise panning between two adjacent speakers to place the sound sources around you. This may be OK for movie effects but not for capturing the spatial nuances of a recording venue.
Ambisonics is a true 3D audio recording format. It is composed of 4 components: X, Y, Z and W that may be captured by the Soundfield Microphone or synthesized by audio ray tracing of the virtual venue.
The four components of the Ambisonics B format are a mathematical decomposition of the 3D sound wavefront at a point in space and are not directly related to any particular speaker placement. It may be decoded using simple linear operations into any speaker configuration. The 3D fidelity of the playback will depend on the number and placement of the speakers.
Note that 5.1 audio is still just 2D. The equivalent Ambisonics format would require only the W, X and Y components. With an additional top speaker you could feel the height of the concert hall in an Ambisonics recording.
One of the problems with Ambisonics is the chicken-and-egg problem - lack of enough media and playback equipment.
The significance of this is that AC3 on CD-R could let more people experiment with Ambisonics - the W, X and Y channels will be pre-decoded to a typical 5.1 speaker placement configuration. The AC3 should probably be recorded at the maximum quality setting of 640kbps. The resulting disk can be played back on any home theater system.
The Z channel can be somehow also stored on the disk so an Ambisonics-aware decoder could get full 3D audio. 3 of the 5 channels can be linearly combined to get back the W, X and Y channel and together with the Z channel you can decode it to any speaker configuration.
There is one particular speaker configuration that makes Ambisonics much easier to understand: imagine 8 speakers at the points of a cube. The W channel is fed to all speakers in the same polarity. The X channel is fed to the 4 right speakers with positive polarity and 4 left speakers with negative polarity. The Y channel is fed to the 4 front speakers with positive polarity and 4 back speakers with negative polarity. By now you can probably guess how the Z channel is connected.

but how many DVD players have DivX encoding?
No current DVD players have MPEG-4 support, not even early DVD players from Circuit City called "DIVX". The early "DIVX" referred to a pay-per-view program that has since been terminated.
To get a DVD player with MPEG-4 support, buy a Dell laptop computer (no, a fellow can't currently build his own laptop to my knowledge) and download and install the DivX codec. Then connect its S-Video and headphone outputs to a regular TV, or connect its VGA and headphone outputs to a compatible HDTV.

"And like that
This achieves full surround playback at somewhat reduced fidelity due to the 256 kbps data rate, but at a size of only 2 Megabytes per minute of 5.1 audio.
I'll repeat that-
"somewhat reduced fidelity"
That was the problem with the original Quadraphonics back in the '70s. The problem was for equal fidelity, you had to spend more than twice as much, since you needed two of everything except the power supply, and it needed to be beefed up.
The bottom line was that a $1000 stereo sounded pretty damned good, but a $1000 quadraphonic setup sounded like the cheap crap it had to be. Fidelitywise, a $1000 quad system sounded the same as a $250 mono system.
They've partly gotten eround the problem two ways- first, the speakers are the biggest expnse, and woofers the biggest of THAT expense. So they got rid of all but one woofer on the mistaken grounds that you can't tell the direction of a bass tone, and renemed all the drivers, calling a woofer a "subwoofer" and a midrange driver a "woofer".
It's still a stupid concept. Twisting my head in a theater because a sound came from behind me spoils the immersion. And with music, I have yet to attend any show where I was surrounded by the band.
Maybe next time they'll get it right- a speaker at each corner of the screen, so you could have up and down movement as well as right and left.
But putting speakers behind you, except in the car with its horrible acoustics, is as stipid in 1992 as it was in 1972.
Quadrophonic "surround sound" is for ignorant people with a lot of money.

Besides, when you're at a concert, you don't sit in the middle of the stage, so the only source of sound is from the front.
Have you ever been to a concert? There's ALWAYS some asshole behind you talking loudly to his buddy while you're trying to enjoy the music.
With surround-sound audio, that experience can be accurately recreated!
What's the point of stereo, anyway? All the sound is coming from a single point -- the stage! Maybe there's a PA system with a big speaker at each end of the stage, but chances are the same signal (or close to it) is coming out of both speakers, so that the balance is the same no matter where in the venue you're seated.
The sole purpose of recorded audio should NOT be to accurately reproduce the experience of being at a concert (what ever that is).
And to the poor shmucks who listen to music on a satellite-subwoofer combo: I hope you don't
ever come near a high-end audio system.
I hope so too, because it would probably mean I would have to get a lecture on fidelity from the insufferable asshole that owns the system.
Our "low-end" systems are good enough for us "poor shmucks". We're happy. Leave us alone.
Sure it's usually edited. But the the producers had to commision the artists to produce the entire song, which is factored into the movie production budget whose cost in it's entirety is passed on through the DVD, distrubted via 100,000s of copies. This cost is also defrayed by movie-goers at the theaters, who's primary job is not to sell you tickets, but popcorn and condiments. In fact, that is the entire reason hollywood exists-- To sell you food. And you think I'm joking. Nope. In any case, since all that cost is a package deal with the DVD I bought, I own the soundtrack to that DVD. Why pay for it twice when you've already paid for it once? And believe me, you have paid for it.

You can get good surround effects from conventional stereo by placing your speakers to your left and right, where your ears are, not in front of you, where your eyes are. After all, we listen to sounds, we don't look at them. Try it sometime. Maybe you won't need to make Dolby AC3 CDs.

Can break bones -- all kids are taught that lesson / rhyme at a very early age!
The author says:
"But be aware that the AC-3 file on a DVD is recorded at 48 kHz. rather than the 44.1 kHz needed for playback from a CD player. And I don't know of any way to convert one from 48 to 44.1 without going through a lengthy decode/sample-rate-convert/encode process which would suffer a lot of fidelity loss."
Resampling is a solved problem. One can do it with any desired fidelity by lengthening the filters to reduce aliasing distortion, although once you get below the least significant bit further improvements become academic.
SSE or Altivec (vector math instructions for Pentium III and Motorola G4 respectively) would absolutely shine in this application - you could probably get resampling rates an order of magnitude better than real-time, modulo some assembly code and a custom app for the job.

Is ushering in an era of newfound piracy capabilities the "right direction"? Is that the official position of Slashdot? Wow... I can't believe this site, recently I've been totally turned off.
Over 70% of the audio in a movie will be in the center channel. Less than 5% (unless you are watching ID4) comes from the rears.
Given this, why does it make sense to treat all channels equally? If the center channel is 70% of the experience, then alloting more data to it will allow the format to maximize the fidelity of the experience.
On a personal note, I have to say that given identical source material, I can't tell the difference between DTS and AC3, nor SDDS for that matter.
