Copy protected cds?
It has been some time since i first heard about those supposedly uncopiable cds, but it is just recently that i have been in enough luck to aactually getting my hands laid on one.
Basically the cd is not recognised as an audio cd by the computer, thus it is not playable on pc, let alone rippable. My guess (I could be wrong) is that is uses some multisession to hide the audio tracks behind some data session, a bit like what kyu did some time ago with his cool hybrid invisible CDs jutsu (Lol if you follow that link to read about the invisible cds, you have to scroll to find that one, it is at the end of the post).
Anyway, for info, our respected hack master has solved the problem in such a short time, and with such a method that i have come to ask myself wether all the copy protection on audio materials today have any sense at all. Of course i will try to describe the method kyu has used with as much accuracy as i can.
First of all, the basic idea is that the cd, protected as it is, will have to be playable by some device. if that device has an earphone or line out jack port, you are done.
indeed, If you have ever bothered tto look at the back panel of your computer, you might have noticed something siimilar to this (Without the captions of course! 
)
Now, using cables such as
For head phone jack entry,
or
for stereo entry, connect your sound source (cd playing device) to the mic (pink) or line in (blue) audio entries of your sound card.
Using an audio editing software (Audacity is kind of pretty good) and after setting your recording options to the appropriate sound input (mic/line in) you can start recording the track(s) which interest you. of course, at first some trials and errors will be necessary to get the perfect volume etc… but the real key here is real sync in pressing play and clicking record
What amazes me here is that this is a real demo of the concept that
Viewable media = downloadable media
Which kyu had adopted for his motto. indeed, this is applicable for mp3 players, cds, even analogue cassettes, it sure is not perfect, especially in the rendering of analogue cassettes, but then, its better than nothing!
The quality obtained with cds are more than descent. Plus, if you finetune the volume factor, The differences in quality for audio tapes arent that great anyway.
So, protected audio content huh? ^_^
@ shallow, first i would like to congratulate you for at least typing a nickname, normally that`s kind of unusual for people who do not agree with me
now now, let us see your questions. What motivates me? i would say its more of a quest for knowledge than anything else.
Also, am doing nothing illegal there. really, it is these people who are infringing my rights. i BOUGHT that ORIGINAL cd, and they limit the way in which i can listen to it. WTF not on me pc? why?? what if my hi-fi stereo player is not in me room?
Also, are you implying i cannot rip it either? nandayo desu ka? what if i want to listen to the music on my mp3 player? oh, mp3s are bad now? since when? go tell that to all the vendors of mp3 players out there, baka na…
And i see u are pro-drm as well. very rare indeed. should i point out something to you? well, this concept might sound new to people like you, but what is the use in BUYING media if we do not OWN it afterwards? because what drm does is not only trying to fight piracy (even that is debatable) but it limits the legitimate honest buyer to enjoy what he/she bought.
I mean come on, interoperability is greatly hindered by drm, so then you want a hardware monopoly as well? not good i say. beit apple / microsoft / sony / whatever, if i buy music, i should be able to play it anywhere i like.
drm does NOT prevent piracy. far from that. all it does is hinder honest people from fair use of their media. possible outcome of all this if drm is implemented:
Sounds good to you? then sorry, you really must be, erm… well, shallow. and btw, i repeat it, this by NO WAY prevents piracy, just read the article above with the new info you`ll get my point
and yeah, am not sure if you realise it but your comment sounds kinda hostile towards me, when i didn`t even do something illegal (and even if i did it would have been none of your business), i just thought i`d let you know
kthxbye then.

hack? my arse! what motivates you to do things like this? You damned pirates!
its because of fucktards like you all that soon DRMised content will be the only thing available. and guess what? it is a very good thing if it indeed manages to keep your mouths shut…
omg, i am utterly disgusted now………

May 8th, 2007 at 8:18 ambeware! anybody who gets caught will ass-teleported straight to scotland!!!
lol nah, just that if you infringe it you will be sent to scotland to receive capital punishment
May 7th, 2007 at 3:16 pmout of curiosity, given zat the jurisdiction for your creative commons is scotland, does that mean anybody outside scotland can do anything he/she wants with your blog content?
May 6th, 2007 at 7:18 amwe will soon have to report you to the authorities!
May 6th, 2007 at 7:09 am@@ leo yup…. in fact i have never used this
except at that time. practically it can be real time consuming and requires your attention during the whole process…
@@ Neha true, but imagine that tommorrow some company decide to release a player with the cable for headphones inbuilt (ie without audio output jack, this would be useless…
May 5th, 2007 at 6:40 amanyway i am for interoperability, (lol @ the guy who is against it to [rp,pte his own hardware
Cool, so as long as you have output from somewhere you are in
Therefore, stretching this concept, the same can be said about protected video cds, as long as there is an output from somewhere, and a way to input it to your pc it is not really protected…
I kind of love this perspective, but it is scary too. imagine that because of such things DRMs get adopted worldwide, (But then again data might be rippable from those special players…)
By the way did you hear the story that in some countries it is illegal to watch dvds using open source software?
