BMG Backs Down Over Copy-Protected CD
An anonymous submitter sends in: "As reported by The Register, on the 5th of November, BMG released the UK's first copy-protected CD (more information on Eurorights and Fat Chuck's). It uses Cactus Data Shield by Midbar Tech, which aims to prevent CD to CD or digital CD to Minidisc copying, along with converting to MP3, but may have other bad side effects."
The submitter continues: "There were complaints from fans and many took their CDs back or wrote to the record company and record shops. Their hard work seems to have paid off since Virgin Megastores has responded to a complaint from one of their customers and said that BMG has set up a helpline to allow people who bought the corrupt version, to exchange it for a real one. Virgin and HMV will also be bringing in new stock of uncorrupted CDs. The message was originally posted to the Official Natalie Imbruglia Bulletin Board (free registration required) in the "White Lies" and "Lillies vs Cactus" threads, but several threads containing complaints against Cactus Data Shield have been deleted so the email has been mirrored on the Free-sklyarov-uk mailing list. This is very good news, but more work needs to be done. Hopefully with pressure from the public other retailers will follow Virgin's example. Also record companies need to be made clear that selling copy protected CDs, that infringe on the public's rights, is not acceptable. The battle isn't over until no new CDs are shipped in these formats so if you find a CD that is copy-protected then report it on Eurorights for the UK, or Fat Chucks for elsewhere, take it back to the shop, and let them, and the record company know your feelings on the issue."
I think the recall probably had less to do with consumer feedback and more to do with the fact that they could have been liable for damage caused by copied CDs, especially since fair use law allows you to make copies in certain situations...
Whatever copy protection they invent, there will always be a workaround...
The movie industry has been thinking so long about an "uncrackable" movie format. They really believed it was secure because otherwise they would have never supported it. Only a few months (I guess) after the release, it was already cracked and DVD-rips are floating on the web everywhere...
If we can crack DVD, why wouldn't we be able to crack this new cd-protection?
I read where the Cactus Data Shield works by corrupting the table of contents on the CD so that a PC's CD player software can't play the music, but a standalone CD player can. What's the difference between how the two types of CD players operate that makes this type of copy protection possible?
Still, it is nice to see that they've come up with a "protection" method that pisses off non-geeks. They're the ones with the numbers that'll make returning defective merchandise really hurt.
It takes balls to pretend that they're looking out for the artists. Piracy can't come close to hurting them as much as the RIAA does every day. It doesn't even occur to them that I might want to store my music somewhere usable instead of on a shelf. Bastards.

Copyright protection will never really work out, because those who want to break it, will break it.. and those who follow the law anyways, won't bother with breaking it.
I have some pirated mp3's on my computer, but they are of bands whos cd's I would NEVER purchase. Generally, if I like even two songs off of the same CD, I go out and buy it.. and most other people out there are similar in nature. The RIAA is just shooting itself in the foot with all their crappy attempts at copyright protection.
I mean, the arguements against copyright protection have been posted here so many times, I think we all know the reasons that it will never work out.. I guess all we can really do is crack all of the crappy little attempts RIAA members make, and then laugh at them for dumb things like this.
The result: a CD-R full of noise, not music. Worse, the generated waveform is of kind to which hi-fi and loudspeaker circuitry is particularly sensitive. Play the noise-filled disc back at too high a volume and - bang - your speakers are toast.
SONY says: That'll teach you to pirate music, you little bastards!
Poor Joe Consumer will be so confused he'll be certain this is because he hadn't bought SONY brand speakers along with the SONY brand DTS professional stadium concert decoder.
With the EUCD (European Union Copyright Directive), that is starting the process of getting incorporated into national laws, BMG would have the law on it's side and copying CDs with this kind of protection would be a crime, even if it was under a "fair use" clause. This is the main problem with this law, for the first time any company can restrict how you use its products. Until now copyright law only affected copying, distributing and modifying the product.
In the USA the won't probably do a recall because all this is legal under the DMCA. Providing "fair use" became optional.
The copy protected CDs use phoney error correcting codes. Audio CD players skip over the invalid data, while the CD player in your computer 'corrects' the data for you. The result is crisp clear sound on your stereo, and pops and cracks on your computer.
Software such as cdparanoia can fix the mangled music.
Everything I wrote above was hearsay, originally read on Slashdot. You have been warned!
This however is different. They're trying to rape me over a cheesegrater. I copy my music to OGG so I can have a long playlist (try as a might - I haven't yet found a affordable 200 disc changer and my computer will have to do). I'm not stealing from them. I paid my money. I want to listen to the music in my way. I will get angry, and write stern letters, and not buy CDs that try and restrict me in any way. I'm not a theif - and I don't like being treated as such.
Mac OS X/iMac-DVD: Track 1 doesn't play, rest okay (ripping not tested)
Mac OS 9/iBook-DVD: All tracks play and rip okay
MiniDisk: Refuses to record digitally
PS2: Track 1 won't play, rest okay
Linux: Tried extracting tracks (cdparanoia), disk is not always recognised first time. Out of 12 tracks, only track 3 extracts cleanly - all others hang with read errors (probably work better with a better drive than mine).
Windows: Runs a custom MP3-player from the CD, playing data from a 30Mb data file of unknown format (according to a report I've just had).
This could be a good wake up call for Joe Six-Pack, if only for the PS2 having problems with the disk. If the industrys can pass it off as "Something that only affects Home Hackers", they can keep the attention down. When it starts going wrong in mass produced home appliances that could never be used to copy it, maybe the public will pay attention?
But this has been said before, last time it was about in-car CD players not playing protected disks...We can only hope public intolerance is cumulative, and people will start to vote with their wallets, because that's the only way things like this will stop.
I bought Codename Outbreak last week, and the copy protection on that game doesn't allow my (Original) CD to be read when the game boots...Have to "Hang" the system to kick start it every time. The site's forum is full of people with the same problem. Copy protection in itself I don't mind, if people want to get paid for their efforts I don't see why they shouldn't. But when you can't use the product you just paid for, something's gone awry.
I don't think I'm very happy. I always fall asleep to the sound of my own screams.
Of particular interest is the section:
During duplication the CD encoding circuitry merely sets the P-channel=0 while recording to the data are, and therefore the P-channel setting of portion 60 is ignored. Thus, during playback, the substituted audio data portion 58 is provided to the digital-to-analog converter as normal data, resulting in audio distortion and potentially damaging the output circuitry. (emphasis mine).
They also don't seem to be as confident about audio quality as I would have hoped:
Thus, the substitute audio data portion 58 of FIG. 4B is ignored, and instead an interpolation, substantially equivalent to the original portion 50 of FIG. 4A, is output, thus resulting in little or no net difference in audio quality between the corresponding track port 44 and 52 of FIGS. 4A and 4B (again empahasis mine).
If I buy music, I want the CD to be as close as possible to the real thing, not with any noise added.

I just sit back and laugh, personally. Because if it is possible for the medium to be recorded and perceived originally, then it can be again. This is why there will never be an end to forgery, illicit copies and that sort of thing.
On that note, why has the music industry not taken a tip from mints? After all, why don't more people forge money all over the place? Because it is too expensive. (i.e. Printing equipment, speical paper, etc etc.)
Just remember it is not the copying that is the problem, it is the distribtion.
Security through promiscuity is no better than security through obscurity.
All of this has meant that the technology hasn't just been introduced with nobody noticing, or putting up some resistance (as I'm sure the music industry would have loved...) - bringing the damage here to the attention of the public is surely greatly influential in BMG and Virgin's decision to back down somewhat.
This is indeed only the beginning, but at least it's a beginning, before it's too late. Pressure needs to be kept up. At Cato's recent
The Future of Intellectual Property in the Information Age conference, Mitch Glazier, legislative counsel for the RIAA stated (somewhat hypocriticaly, imho):
I can't speak for everybody else, but the RIAA doesn't seem to be anywhere closer to the answer than it was a year ago...
I had a reasonable argument and I backed it up with a reasonable idea. If we all sit around and say that encryption is bad, we are just shooting ourselves in the foot. I think that we need to quit fighting this on an encryption by encryption method and make some real progress. In the end we all want to be able to access music and software and other things online, and in the end this means that there are going to have to be control systems. We should back up, and start fresh with some new inititives that are followed by a wide variety of companies.
Unfortuneately some (like those of us in Los Angeles) can't see it due to weather conditions (what the hell is this? fog? in LA?!?!) and/or the wonderfull joy called Light Pollution (what officer? my headlight's weren't on? are they now? I still can't tell)
I'm out of my mind right now, but feel free to leave a message.....
Also I wholeheartedly agree with Virgin's statement: "As retailers we do support the fight against copyright theft, however this should never be at the expense of the customer."
I have no objection to meaures that prevent only illegal or immoral behaviour, but by preventing digital copying the record companies are preventing the public from making legitimate, legal and moral uses of their CD, such as making a backup copy for safety reasons or transferring to a MP3/Minidisc player. I am also unconvinced that such draconian measures need to be put in place since the availibility of MP3s has not been shown to decrease CD sales, in fact the contrary seems to be the case, as shown in the paper "The Use of Conventional and New Music Media: Implications for Future Technologies" by Brown, Geelhoed and Sellen (2001).
This paper argues that intangible files, such as MP3s will never replace the role of physical objects such as LPs, CDs and casettes since music enthusiasts are collectors, and just the ability to listen to music is not enough, rather a tangible object is desired. Instead of trying to eliminate duplication of Music (which, both historically and technically, can be seen to be impossible), they would be better to use it to their own advantage, which would help them, the artists and the public.

The money comparison is a great one! If I wanted to copy mony for my own purposes (i.e. to extend the available funds in my Monopoly board game or for use as a gag gift for a friend) it would be absolutely no problem whatsoever...I could put a bill on a photocopy machine, or if I wanted to make it a little fancier I could use a color one or my scanner and printer. However, if I wanted to use it illegally (outside my rights) and therebye distribute it, things would get difficult. I don't think my local Quick-E-Mart cashier will take my black and white one hundred dollar bills printed on cheap bond paper.
Before someone gripes, yes I know that it is illegal to copy US money without resizing it to make it obviously not legal tender...but thats not the point...copying for personal use is not an issue whatsoever because distribution is nigh impossible.
I'm out of my mind right now, but feel free to leave a message.....
So, they can only currupt the data under certain conditions. Perhaps someone could determine under what conditions the errors are correctable, and use that knowlege to manually correct for the them? By only chosing particular blocks, the protection is giving the cracker clues as to how it works.
Do the maths and work out what the loss of one section of each frame is over a complete CD - its a reasonable portion of one track that is effectively missing.
Nothing is said about the fact you are buying a faulty product either, nor that chunks of it have not been supplied.
I guy at AudioT in High wycombe (Excellent HiFi chain in the UK) who is quite knowledgeable about HiFi electronics told me that some copy protection systems can blow some high end audio kit due to the noise at frequencies not normally present being transmitted through to the speakers.
Apparently the out of normal frequency range signals can bust the tweeters and crossovers.
Has the copy protection system been throughly tested in this regard? I doubt it.
Also how long before someone developes a way of gettign round the copy protection, has the record industry learned nothing from the digital watermarking debarcle.
Modern definition of an expert: Someone who comes from far away with a powerpoint presentation.
First up, this is pure hunch, so flame on if I'm wrong. There seems to be two pieces to this problem:
1) The TOC appears to be nailed so that many players looking for data can't find it. Stereo components look for the lead in track - not the TOC, so they are unaffected. PS2s and PCs look for the TOC - hence are affected.
2) If your player overcomes the TOC issue, then the data itself is full of errors that can be fixed by a domestic D-A converter, but not by blindly accepting the data (as PCs tend to do if the CRCs stack up). The algorithms in the domestic D-A converters are well known.
Neither of these problems seem impossible to resolve. I give it 3 months before all rippers have a check box labelled "rip as domestic CD player" or similar. This is not an "encryption challenge". It is a challenge of emulating a domestic CD player's D-A converter in software. This is the achilles heel: they have to maintain compatability with the huge installed base of CD players out there.
"instead an interpolation, substantially equivalent to the original portion 50"
It means that the already-ripped track image can be processed in similar way giving the result equivalent to the audio player's one.
The record companys are going to be just as effective at alienating thier own customers as Microsoft and that is what will bring about real change. I am all for it go ahead copy protect CD for players that were NEVER designed to have that done. I promise it will not affect my music listening habits on bit. Wait ... who's there? The FBI! Sorry gotta go.

What happens when a company sells a product that nobody wants? Um, let's see, that can't be hard to figure out.
They're killing the format. Plain and simple. And forcing people to think of alternatives, big time.
We are lucky that people^H^H^H^H^H^H geniuses like P.Diddy and eminem grace us and allow us to listen to their music. If they so wished, they could keep the music to themselves, but they choose to share.
These people are practically gods in my view. They could out-perform the likes of Beethoven and Vivaldi with their eyes shut. Infact, i would go as far as to say that Mr. Diddy invented most forms of musical notation, and Mozart simply finished it off.
Along with mathematical super-minds like Bill Gates, these people are the ones that drive civilization forward, unlike hippies such as Torvalds who think everything should be free and open "Ohh yeah, lets dance around in a free open world where sunflowers grow and where there arn't any bad people." I for one, think eminem should get all my money, I would actually work as the great mans slave - simply paying all my money to him.
This post is not flaimbait, trolling, offtopic or even sarcasm, it is my actual real view into the troubled world of copyright and IP.

Ok, this copy protection stuff has been talked about for a while, and I can tell you, it's here weather we like it or not. Why do I say this? Because, every law is on the record companies side aganist piracy, the only thing that might go against the DMCA is the Home Recording Act which was implemented in 1992 when the MiniDisc came out. It clearly states what's fair use, and many laws allow making backup copies and some even go as far as to say copy protection is illegal. But, are these CD's totally uncopyable? No. As many have pointed out programs like CloneDisc and Nero are capeable of making 1:1 copies of audio CD's if your hardware supports it. So, you make a perfect 1:1 copy of a copy protected CD, theoritcally, it should play fine. The biggest problem is ripping to (crappy) formats like MP3 or (even worse) OGG. (I'm a MpegPlus man myself). The CDFS.VXD ripping program uses burst mode copying, and therefore doesn't auctually use any error correction, but, it can recover from errors better than using say, EAC's Secure mode. My G.F. bought the new Michael Jackson CD and brought it over to my house saying it wouldn't play in her car or her DVD player. So, I popped it in my Apex AD-3201 and nothing, it wouldn't play it. It showed up as an audio CD, but both the analog and digital outputs lost sync. Popped it in my Sharp player, and it played fine, my MD deck even recorded from it (as most CD player's digital out's aren't RAW data, they're error corrected PCM). So, after some reading I found it was copy protected. I put it in my drive, and tried to rip it, alas, nothing. I then switched EAC over to burst (XP Pro doesn't support CDFS.XVD to my knowledge) and granted it ripped at 3.4x, it ripped (my DVD drive usually gets about 8x) They say the protection won't affect audio quality as much, bull. If you have good ears, you can tell the audio lacks a certin oomph (same oomph missing on CD that's on Vinyl, it's not really noticeable, but, it's there) Also, let's not forget HDCD, HDCD is dependant on a good audio stream, if they corrupt part of it, theorically, AFAIK, HDCD won't function.
Given that one of the so-called anti-piracy systems has been bypassed, according to this link, I wonder why the companies even bother. Also, these work-arounds are more likely to be used by bona fid pirates than someone unhappy that they have a CD they can't make their MP3s from ( yes, I know its a generalization, but the general point remains ).
Jumpstart the tartan drive.
I still stand by the idea that copywrite protection laws are the first casualty in the war between geeks and corporations that will eventually end in the anarchistic Geek-governed utopia, which is simply a slight variation on Socrates'/Plato's Utopia.
All I know is that I'm keeping my DNRC card handy.
(Please save all flames saying I'm a moron for believing this. I know I'm being delusional, but heck... a man has to dream...)

I'm allowed to make copies of my music for my own personal use.
I'm allowed to lend an original CD to a friend.
That friend can copy it for their personal use.
I am NOT allowed to make a copy and give it to a friend.
If I make a legal copy of the music (say for my own mix CD) and it damages my equipment, you'd bet I'm going to go after the music companies. We don't have the RIAA here.
You can accomplish anything you set your mind to. The impossible just takes a little longer.
I don't think the record companies understand that ripping a cd isn't the only way to pirate the music.
Increasingly, the MP3's being traded online don't come from CD, but from television. Nowadays, with digital cable and Sat TV all over the place, the quality of the audio coming in over your TV is as good as any CD. Digital audio out to the PC, a little record and waveform edit later (to get rid o fthe beginning and ending you messed up), and boom, perfect track.
All they are doing with these stupid schemees are annying people. They are not solving anything.
I haven't really read all of working of this, but from what I understand is that they won't play on computers, but will on normal CD Players. SO! All you need to do is to play the CD on your stereo, and plug the recording output (I've got 3 on my JVC amp, 2 on my JVC cd changer) into your audio input of your computer. With this, you can record it on your computer with the sound recorder, or download one. Sure it's a very roundabout route, but won't it work? Because this way is more or less sticking a microphone infront of the speakers, but with much higher quality. I'm not too sure, but thats my $0.02
If you sell a copy-protected CD that makes it next to impossible to rip, it may well prevent 99% of people out there from ripping it.
Those 99%, as well as all the people who don't want to buy the CD because of its damaged nature, will get on their favorite file-sharing service and search for the songs.
Care to guess how long it will take for the cat to be totally and irretrevely out of the bag? Remember the proportion of MP3's out there that were recorded live, which is also exceptionally difficult to do.
It will make an interesting test case when a punter sues Sony for blowing up their loudspeakers after playing an allegedly pirate CD...
Why is The Register calling my backups, pirate CDs?
It looks to me like the record companies are shooting themselves in the foot. If word spreads that CDs are being crippled in this way surely it will discourage people from buying CDs in the first place? Why spend money on something that has been crippled when you could just download the album from a file share somewhere...
Judging by everything I've read, not just here, these copy protected CDs won't work in my Sony car CD/MP3 player, even as a CD. I bet there are alot of other car cd players out there that they won't work in either. Stupid stupid stupid.
Ah well, it's not about the little people anyway. It's all about greed and control...
Isn't that always how it works though? The last steinberg product I ever bought was a copy of LM4 -- it had this *whacky* copy protection that was incompatible with win2k (the installer always detected a pirated copy in win2k, and we're only talking about a 60$ program here) ... So I ended up having to use the pirate version anyways ... Steinberg! listen up! I'll start buying your products again when you grow the fuck up.

It was overcast where I was- thank you so very much for reminding me about that fact!
Thanks for making me see the light! Why would I want to support a band who doesn't want me to listen to their music? I really mean it.
For some reason, this issue WAS pissing me off, but now I see so clearly that if I let the RIAA tell me what to listen to, then I am clearly part of the problem.
Grumble, Grumble
From the Register article, and from the patent filing that another reader posted, it sounds as if the speaker damage might have been a design goal, or at least a side-effect that they are using to pitch the technique as "punishment" for "pirates." "You copy our CD, will ya? Let's see how you enjoy it when you play it on your blown speakers?!?" Well, let's see how many CD I continue to purchase to play on my blown speakers.
There ain't no rules here; we're trying to accomplish something.
The main reason for this was that the distributors only let us return opened product at a penalty, if they let us return it at all. We'd replace defectives for the same title, but that was the limit of our liability.
Of course, now that the labels are sending out intentionally defective product, I'm glad I'm no longer in the business. These are the same labels that promised us that cd's would be less than $10 within a few years after the arrival of the format.
Thing is, one of the ugly side effects pointed out in the letter is the fact that the fallout from this whole thing unfairly places Mr. Retailer right in the middle. The label doesn't have to listen to consumers' complaints. Grr...

I can't see the point in investing in these elaborate copy protection technologies in the first place. There's always going to be a workaround as long as there are stereos with audio outputs and PCs with audio inputs. It just means that you need a stereo and an audio cable and an extra 2 minutes to hook them up. As someone already noted this will deter Joe Sixpack, but not serious music 'pirates'.
It doesn't matter how difficult it is to copy the music, because once it's copied it can spread illegaly as much as any other song through filesharing systems. Only now people are forced to use the mp3 if they want to listen on their computers, and casual listeners can't easily copy the music to mp3 for personal fair use. Schemes like this will hardly affect music 'piracy' at all, if anything they'll make it more rampant by marginalising PC listeners.

Won't this hurt Sony's interests in producing portable players? I'm sure they thought of that, so there's probably a back-door designed specifically for Sony software to rip a sony CD, in a "sony format" for sony's new portable sony player.
I thought it was legal to rip MP3's for personal use, such as playing them in car stereos, or using a hard drive as a CD storage device. In fact, I think there is a whole industry who believes this...
Any portable electronics made in any other country? It's time to demand a tarif on Japanese electronics, because they harm the interests of other electronics companies. (Yea, I know it's just sony, but can most countries tarif a specific manufacturer)
Ok, I'll admit I am not a l337 |-|4X0R, but seeing as the "corrupted disks" contain a player for the tracks on the computer (if I read that right) would it not be possible to correct the errors on the cd?
Exactly like the DeCSS key were obtained, in a way, one company (Xing in DeCSS's example) does not protect the keys in the app enough and one person discovers this.
Or, compare the data track to the pre-ripped mp3's for a higher quality rip (say 320K vs 128K) by using the ripping routines compared to the data extraction routines.
I'll probably wind up repeating myself (developers, developers...) but the mp3 codec is not "bad/illegal" in and of itself but it seems as if the 'use of' is being villified or "circumveted" (ins't that illegal under the DMCA?).
Sometimes I really, really wonder what the MPAA/RIAA et al hope to accomplish with these so called "technologies", but all too often it is over looked that your rights of "fair use/space/time shifting" are not at issue but the excercising of those rights are.
Trying to legislate morality, humm, deja vu, all over again.
If it is not on fire, it is a software problem.
Why does this prevent ripping? You can rip to WAV (ignore the p-blocks which a CD-reader does)? It only explots the fact that CDR specs has a "fault" on it when you directly pass them bit for bit data it just doesn't flag the control data at all.
I mean (not to violate DMCA or anything), there could potentially be software that would strip these p-blocks out of the read stream before passing it to the CDR drive since the p-blocks are just "potentially circuitry damaging" signals and don't contribute to anything to the positive CD-features.
In British Columbia (as well as other areas, I'm sure)if a theif slips on some ice while breaking into your home, he can sue for damages. In the 80's a theif successfully sued a car owner for putting razor blades on his car stereo and caused the theif to loose 2 fingers.
Blowing up your speakers (which couls also do damage to whatever they're hooked up to) as well as inconvienence, trama (from the 'explosion), public embarasment (if it happens while you're hosting a party or blowing someone else's system if you lend the CD to someone)could equal a very large and nasty lawsuit.
If you can sue for your coffee being too hot, why not go for the gusto?
The GEEK shall inherit the earth...
I think that recording industries making deliberatly damaged cd will :-)
upset not only consumers, but also AV electronics manufacturers.
In a mall or in an household appliances show, the devices you could
find are DVD players, CD recorders, AV amplifiers (with digital inputs),
and ghetto blasters or similar small CD/Tape/Tuner combo.
Separate power amplifiers, tape decks or tuners are a rarity in these
shops, not to mention turntables. If you will buy one of these, you have
to resort in a specialized hi-fi shop, and even in one of these you
can find more CD writers or DVD players than cassette recorders, and
anyway a decent dual tape deck costs more than a CD/CD-RW combo.
The average consumer, having to buy some appliances, is easy that
will buy a DVD player plus an AV digital amplifier rather than a
standard CD player. And these damaged discs will not play, either because
the DVD player got confused by the wrong TOC or because the DAC into
the AV amplifer doesn't recognise the damaged signal from the Toslink
input.
If the consumer goes into an hi-fi shop to buy a new CD player, is
possible that will have similar problems: newer ones that will read
both CDR and CDRW, can also handle multi session audio CD. I think that
a person that buys, say, a 900 euro Marantz CD 6000 KIS, or a 2400 euro
Teac VRDS-25X could become a bit upset if can't listen most of the new
CD has just bought.
Maybe will tell what happened to one of his friends, that will stick
to the older CD player and instead will buy a 1000 Euro Thorens TD 166
and a 600 euro Ortofon MC 20, a decent soundcard, and then will make
mp3 of all new 33 rpms he bought.
When I buy a CD I pay for 100% of the music. When a record company deliberately puts errors on the CD so my player is in error concealment when I'm playing a pristine CD, they are robbing me of my $$ and MY MUSIC! Unlike error correction, error concealment TAKES AWAY DATA (read: MUSIC) THAT CAN NOT BE RECOVERED!! Now, let's say that I get a scratch on my (formerly pristine) CD. NOW there are NEW errors in addition to the ones PUT THERE by the record company. NOW my CD won't play at all...but a CD without THEIR (added) errors would. Therefore, the math is this: I pay 18 bucks for a CD and get about half of the data that's supposed to be on said CD. Also, I'm getting a CD that isn't nearly as tolerant of scratches as the older ones. Also, I'm getting a CD whose songs I can't put on my Rio...or play at my computer..or on the DVD player in my living room...I can only play it on the stereo in the den... Finally, I'm getting a CD that just might blow up the amp and/or speakers of said stereo in my den.... In other (simpler) words, I'm being RIPPED OFF!
Ruri put it best: "They're all idiots."
Ok, so Sony, who cowed my college into banning downloading of "copyrighted information" (not just Sony's, mind you, but everything, which, because of current common law, actually does include everything, even copylefted stuff), is going to create CDs that, when copied, destroy other people's real property.
gah
Ok, let me get this straight: I can play the original, because it is read. But, magically, I can't play a burned copy? Ok, if this works with traditional copy methods, why not just instead ignore distinctions between all kinds of data on the cd, control, audio, digital, etc., and just copy an exact replica? Correct me if I'm wrong, but if it can be read, it can be written. Anything else would mean that it couldn't be read in the first place.

Counterfeit music stores were everywhere. Racks and racks of cheap, unlabled tapes housed in cheap covers with questionable artwork (side note: artwork blacked out "excessive" female skin in accordance with local laws but Madonna's erotica-laddened lyrics went unscathed). The recordings themselves were suitable enough. The tapes made use of extra space by including a few tracks from simular artists (kind of a bonus). And the product, while cheap, was inexpensive.
One would expect that legitimate music products couldn't exist in this environment. One would be wrong.
First - at the time, it seems that CDs were too expensive to create (CD burners weren't as inexpensive then). Legitimate CDs were sold on racks right accross from the counterfeit tapes. Which kind of makes sense - the product was too expensive to create and sell cheaply, yet there was added value in this format. There was a market for them.
I was very suprised to find legitimate tapes at a store in Kuwait City. Most of the music stores I had seen were, frankly, low-budget affairs. This particular store would have been at home in any mall in the US. It was chock full of CDs, listening stations, stereo equipment, conterfeit tapes, and a wide selection of legitimate tapes. Prominent over the legitimate tape selection was a (I believe Sony) sign extolling the high quality of legitimate tape music products.
And the legitimate tapes were selling.
The price for the legit tapes were a bit more than the conterfeit tapes. But they had obvious advantages in quality. That combination of a reasonable price and better quality tape offered a competitive product to cheap knock-offs.
Its interesting to watch the music industry now. Their control over distribution is crumbling. The market they're used to is being eroded by the free flow of data (legitimate or not). Its got to be stressful to watch your industry's business plan evaporate.
But all's not lost for them. They've competed in this kind of market with the Middle East. It all comes down to a competative product. Provide something of value at a reasonable price. The music industry has the resources to create a great product at a price point that would be difficult for conterfeiters to compete with - and may even make it worth the public's time to purchase rather than try and copy/pirate.
All COTS cd players have a DAC. Acheiving perfect digital reproduction is a simple matter of intercepting the clock, channel, and data lines going to the DAC. The cd player control circuitry has already made the error correction, and this data is ready to be converted to analog. The data will almost always be in I2C format (I squared C). Some professional equipment uses this format and can accept it directly. There are commonly available chips to convert i2c to sp/dif (this is how you can upgrade your old analog output cd changer to a analog + digital for cheap). There is also the possibility to build a usb interface for ripping. If you do that you might as well hook into your cd player's control buttons and make a computer controled cd changer.
Would be a fun project for some EE student.
and if you don't, at least read the damn post
they have a US bill with "You are not a slave" on it in what looks like red texta.
But there are also other reasons to copy money. If you are trying to convey the meaning of money without text, a picture is the obvious way to go.
I would also like to add that in "my" opinion, the problem isn't the illegal copying, the problem is the overpriced CDs.
Here in Sweden, most CDs cost more than $15 and an empty CD cost less than $1. Considering that the music companies probably don't even pay anything near $1/CD when pressing them, you'll wonder where all the money goes?
Yes, they do have marketing costs, recording costs and salaries, but do the really need a $10(?) margin for every CD sold? And IIRC, LPs cost around $6 to $10. Don't try to tell me that it would be more expensive pressing CDs than LPs. Guess they noticed that ppl would still buy CDs at a much higher price even after they reduced the manufacturing costs.
I don't think most people would go through the hassle of downloading and burning CDs if they could get an original press for, let's say, 6 to 8 dollars?
But I guess it is easier for them to sell 5 CDs than 15 and still make the same amount of money. Logistic costs and stuff like that.

For that reason, the name 'Cactus Data Shield' is very appropriate: when ripped it is full of 'spikes' ruining the music, when perfectly interpolated it may possibly be sample-for-sample identical (assuming the substituted samples are ONLY those where surrounding samples interpolated will return the exact, precise amount- I'm not at all sure this is a safe assumption), but when imperfectly interpolated the _best_ output still has traces of the 'cactus spines'- like stubs :)
On a CD player with inferior interpolation it is probably slightly more sonic degradation than you get from DVD-A watermarking because watermarking is bandlimited to avoid the more sensitive areas of hearing, and this 'residual cactus spikes' effect will reach into the highs and spit out artifacts on steep wave slopes.
I know that in debugging azumith-correction algorithms I could hear high-frequency artifacts of just one sample duration when they were of this nature- a departure from the even slope of a waveform. I would respectfully suggest that the dangers of inadequate error correction are more severe and audible than the CDS guys are ready to admit, and that on many CD players traces of high frequency crackling and grunge will still be audible even after 'interpolation'...
As an indie music maven and audio tool coder I have to say I am just tickled by all this. How nice of the music industry cartel to ruin the quality of their products FOR me, thus making it easier for people in basements and dorm rooms to produce music that's actually better than the cartel makes. A few more years of that and they'll have done serious damage to the former popular opinion that industry music is more professional than unsigned music :)
> I have no objection to meaures that prevent only illegal or immoral behaviour
I don't know such a thing, nor can I imagine one.
My conclusion: All "copy protection" is evil, only more or less so.
(BTW: My personal, *absolutely minimal* requirements for "fair use":
I own the work for my personal use and that of my household. I can do with it whatever I want as long as I don't give it to other people (or those of my household).
Most importantly:
- I can copy it, with full quality, any number of times, for backups, my car, my mp3man etc.
- I can use it fully with standard software (i.e. complying to open standards, implemented by open-source software)
- (Implied by the last requirement:) No one controls or watches the *use* (play etc.) of the work.
Any copy protection violating any of that is unproportionally deprives me of my rights and is thus IMO unconstitutional (even if written into a law).
Aah, but that's just it. Most good hi-fi audio amplifiers are broadband amplifiers. For example, my NAD 2200 power amplifier uses 25mhz transistors, resulting in bandwidth far exceeding the audiable spectrum. The unit has two sets of inputs, one of which has subsonics and hypersonics filtered and one which does not. If you're using a pre-amp and CD player which you trust not to induce its own junk into the audio path, you use the unfiltered lab inputs. If not, you use the filtered inputs to avoid wasting capacity amplifing signals that may potentially waste amplifier capacity and damage your speakers. In an unfiltered configuration, you could in theory damage your speakers by playing a CD with lots of subsonics and hypersonics just like the poster describes.
This sounds wacky, but I think it's true. I got a bunch of MP3s of Primus. I had heard the odd Primus song before and after hearing a whole bunch of MP3s I realised I liked them.
Now I could have just burnt their songs onto CD-R and be done with it. I only listen to CDs on a discman these days anyway, so I don't care too much about sound quality. 128kbps MP3 is good enough for me.
Instead I went and bought every Primus album I could find. I'm not sure why. It would have only cost me $5 to put all the MP3s onto CD-R, print off the album covers, and I'd have something not half-bad without the effort. Buying the CDs was a relatively difficult thing to do!
your speakers are not designed for this. your crossovers (if you have any... real high end is tri-amped with active DSP systems shaping the audio for each driver.) will dump to ground anything over 50Khz and dampen the low frequencies.
Low end, the worst thing possible is DC, and your amp and crossiver will not allow that in.
High end... >50Khz will do nothing to a tweeter... it cannot make it past the inductance that is the speaker coil, let alone the components.
It's just basic electronic theory.. capacatance, resistance and inductance. then in speakers acouatical engineering comes in... but that has nothing to do with the audio source just reproduction of the audio.
Do not look at laser with remaining good eye.
The picture cycled from clear, to grey, then back again. Hum. Checked the user manual, and it was due to copy protection! The DVD player had to be plugged directly to the TV or it wouldn't work. But I wanted to play the sound through my good speakers, not the TV's speakers. I tried plugging it into the amplifier. Now the video was clear, but the sound was distorted. User manual says, copy protection: it's supposed to be that way. OK, so I hooked it directly to the TV. Now I could play DVDs. But now the VCR wasn't plugged in. Perhaps I could hook the VCR through the DVD player? No, no terminals for that. Perhaps the TV had two sets of video terminals? It did!
I still don't have the DVD playing through my good speakers. I haven't exhausted all combinations of terminals though. Perhaps there's an audio output from the TV that can be routed to the good speakers, without turning on the copy protection noise or the video distortion.
If the TV didn't have the spare set of video inputs, I'd send the DVD player back because the copyright protection measures would prevent me from using a VCR. But the TV did have a spare set of video terminals. Not being able to play the DVD through good speakers isn't annoying enough to be worth the effort of returning it.
I will not be participating in the DVD "revolution", and I stopped buying music, cold turkey, last year after Napster was shut down, and two reports came out : 1) record profits for the music industry *despite* napster, 2) admitting they'd been grossly overcharging for CD's for 18 YEARS!!!!!!! Forget 'em, I won't fund their greed any more. Use the money you'd be donating to these obnoxious pigs and spend it on a high speed net connection, large hard disk, CDRW setup. It's payback time.
I don't know about you, but my cable system has a lot of pure music-only channels - I don't think he was talking about grabbing the audio off of music videos.
That sound stream may be equally compressed, but I don't know of the details offhand.

Oh so I get it an audio CD player is analog but a CDROM is digital... Bzzzt.
Well, you're right, but you've missed what's going on:
The audio standard (for CDs) trades longer playing time for reduced ability to absolutely correct errors. (There's less redundant data.) The digital standard (for CD-ROMs) includes more check-data with lower absolute capacity. (You can't get a CD's worth of .WAV files on a CD-ROM.)
The playback/reading methods are also different. When you load a music CD and press play, the resulting digital datastream is routed to an onboard decoder chip which converts the digital audio data to analog and sends it to the drive's audio outputs. The decoding process designed to tolerate all but the most severe errors: First it corrects any errors that it can, then attempts to conceal any errors that it can't correct. Only if the concealment doesn't work does it fail, and then only for a limited time. (A 1/2-second burp on a 79-minute disc shouldn't prevent the rest of the disc from playing.)
When you're reading a data disc, (or when you're using a rip program that reads the audio CD as digital data), you use the drive's internal data-validation routines. With data, you (usually) don't want errors that can't be fixed to be quietly concealed (think tax tables with wrong numbers in them, or a one-byte error in an .EXE), so the drive is set up to choke if it runs into an error that it can't correct.
What the Cactus and related systems try to do is add just enough bad bits to the data stream that CD-ROM drives will choke when reading the disc as data, without adding "detectable" degredation when the same data is processed as digital audio through the audio decoder chip. Problem is, that assumes that all players have the same tolerance for bad data (unlikely), that the all players will react to bad data in the same way (so you can predict what corruption is "safe"), and that all listeners have the same standards for what's "undetectable" (don't make me laugh). Plus the fact that intentionally corrupting the data makes a less robust disc; one more likely to fail if things like fingerprints, scratches, or dirty laser lenses further degrade the signal. Not pretty!
Yes, there should be a way around this. IIRC, cdparanoia does something like what you suggest. I don't think you'd want to implement this at the driver level, though, unless it was coded to allow you to switch the correction routine on and off. Because, as noted above, there are times you need to know that the data's bad and can't be fixed (or has been fudged).

1.. If the player can read the original, then so can a copier - I don't see how the data can be magically readable by one device and not by another when both devices predate the format.
2.. I hope this doesn't catch on - I don't want to go back to furtling around though boxes of 5 inch plastic disks to find the track I'm after - making you keep the distribution media is like having to keep all the packaging from everything you ever bought.
This is not the way to go - ownership needs to be registered somewhere (or "right to listen/watch etc"). Thats the way software license mostly work - physically posessing the distribution CD does not mean you have the right to use it - this is dealth with elsewhere - the disk is irrelavent. Just as having a brick in your hand does not give you the *right* to chuck it through a shop window and rob the place. This crypto CD plan is like trying to invent a brick that will only allow itself to be used for wall building - "Powered by stoopid" will be the logo no doubt.. (or "idiot outside".)
In the name of Digital Rights Management, corporations prevent you from editing or copying stuff they have published to you. This is odd, and at at odds with the spirit of Copyright.
No-one can tell you how much of their book to read, or the order you can read it in. Why do they presume to do so with sound or video? Why must I look at a green FBI notice for 15 seconds at the start of a DVD?
It is the act of re-publishing where the potential copyright violation occurs, not the act of viewing or editing.
Reject uneditable content and say why. Rights are for people, not digits or management.
- Put cd in regular CD player.
- Cable from line-out of CD player to line-in jack of sound-card
- Start sound-to-wav converter and CD player.
- Encode wav to mp3.
wavrec and bladeenc work good under linux for steps 3 and 4, but there has to be something similar for windoze.It's easier to rip straight from the CD, but the quality difference probably isn't noticeable after MP3 encoding (this is a guess). This method guarantees that there will be MP3 on the net of any decent tracks 20 minutes after the CD hits the shelf. And once the first one's out, that's all she wrote baby. Eat my dust, RIAA!
But while we're doing this, don't forget to oppose the SSSCA absolutely and to agitate for the repeal of DMCA. The real danger lies in the next generation of hardware and formats, where more protection is built into the hardware.

Many color photocopiers implement copy protection (seriously!). They will detect that you're trying to copy money, and screw up the colors so it looks fake (unless you resize it). Try it sometime. I'm not sure if color printers have the same "feature".
I doubt a any real high end audio buff would admit to having a DSP anywhere near his/her system.
Some high end and not so high end amps have NO DC protection.
whatever, if you dont have DC protection then you bought crap... Ever hear of Fuses? only the crappiest amps dont fuse the outputs.
all these posts to the effect of "cant i just plug my 20$ stereo into my 5$ sound card and encode the resulting wav with my latest eleet hax0r copy of XING/FHG/whatever..." perfectly illustrates why i stopped collecting music retrieved from the internet a long, long time ago. If its good enough to listen to, its good enough to either own the cd or acquire the cd from someone who does and rip it yourself, if you give half a shit about quality.
"Small Claims Court". Small suits like this are what small claims court is all about. A lawyer is not required (but it helps to talk to one first) -- the procedures are steamlined and are designed so that non-lawyers have a fighting chance, even if up against a real lawyer. There's a statutory cap on the damages you can claim ($2500 in Maryland, IIRC), but other than that there are few restrictions. It's about the only venue left where an ordinary person can get justice against a megacorp -- frequently they will accept a judgement without a fight, because it would cost them more to send a lawyer then it would to pay off the claim. The downside is it can take a very long time to get a court date, because of the tremendous backlog, and you do have to pay a bunch of fees and do a lot of paperwork yourself.
Why is it that the proponents of "one nation under God" are so eager to get rid of "liberty and justice for all"?
A similar thing happened here in Oxford - a student was found to have downloaded four (yes, four!) MP3s of Sony material. Suspended, I believe.
The Taliban had an effective method of preventing people from copying cd's... Unfortunately it also meant never listening to CD's (or tapes or radio or TV) ever again.

Ah, yes. I still have a scar on my finger from an incident with my Dynaco Stereo 400. While DJ'ing a gig, I noticed that the sound had stopped from the left channel. Upon investigation, I found that a metal buckle had fallen across the output jacks. I reached over and pulled it off--Damm! it was nearly red hot. Even more impressive was that the sound immediately resumed. Back then 200 Watts a channel meant (FTC rules) 200 Watts RMS from each channel, all channels driven, basically all day long (I think the test was an hour, but anything that could make it through the test could do it forever). Unfortunatly, consumer electronics companies bought a majority share in the FTC, so the "400W" amp in the store today couldn't sustain 400W if it was on fire.
All I was saying was that the RIAA can (and does) affect people in other countries. I know and listen to plenty of stuff from Scandinavia, England, and elsewhere. It still sounds like you have gone through the RIAA to get about 20 of your CD's.
