making backup op copy controlled cd

[Dude]

hi

I have bought a cd with the copy controlled icon (the logo is not the same as this one http://www.prelude-klassiekemuziek.nl/copycontrol.jpg, but also a black circle and it says 'copy controlled') and I want to make a backup of the cd (to WAV) using dbpoweramp reference. It seems this works (dbpoweramp says 'secure' on each track) and I can play all WAV files without any problems. So can I assume that all tracks are ripped correctly when using a CD withe the copy controlled icon?

thx in advance

Yes, the rip was ok. For these type of CDs make sure you have the option to disable the autorun (CD RIpper >> Options).

can you tell me what happens if autorun is enabled?
i noticed e.g. winamp doesn't see the CDDA files so can't play them. But dbpoweramp can do it. So does dbpoweramp cracks the copy protection then or how is it possible ?
I was also wondering if you could tell me how the copy protection works because dbpoweramp doesn't have any problems with ripping.

thx

Some CDs install nasty system altering programs (like Sonys Root kit stuff), that option removes that possibility.

so if I understand it well:

- disabling autorun just doesn't give the CD the chance to run the installer

- copy controlled cd's just contain normal CDDA tracks like non-protected cd's and dbpoweramp just reads these like on normal CD's

Are both sentences correct?

thx

The second one is not necessarily true, Dude. Some CDs employ a method of copy protection that involves putting audio errors into the audio that most CD players filter out, but which computers dutifully copy and therefore the ripped CD sounds horrible. I believe these CDs don't have the "digital audio CD" icon on them, as they are not technically Audio CDs according to the Red Book standard.

So when dbpoweramp can see the audio tracks (like my CD) and can rip them and tells 'secure' for each track, everything is correct and the CD just contains CD audio tracks?
What happens with a cd that behaves like you describe here: will dbpoweramp see the audio tracks and/or can it rip them?

thx

dMC will see the audio tracks and rip them, but they will sound awful with pops, cracks, and hisses in the audio file.

I doubt on such a cd it would be shown as secure.

so nobody has never tried to rip such a CD yet?

I have one of these most undesirable Copy Control CDs - Chimera by Delerium.

dMC rips the tracks fine, although really slowly as it has to "re-rip" a whole load of frames for each track. Some of them show up as Secure with a tick and others and Unsecure with a cross but on listening to the ripped WAVs all the way through it sounds fine - and I'm very familiar with the CD. I'm sure there are some errors but they are too small to audiably detect and since there is no version of this CD in another region that doesn't have copy control it is the best I will get from it, I think.

to the developers of dbpoweramp: can I assume that dbpoweramp doesn't crack the copy protection on that kind of CD's or am I wrong?

thx

If the CD has the "inserted noise" copy protection, that kind of protection cannot be cracked as the CD itself is deliberately made defective.

and all other protections are cracked (so like the CD I ripped and gave good results (all secure))?

[LtData]

I would hesitate to say "all" other protections are "cracked", or more appropriately, bypassed, but some of them can still be ripped by dMC and be secure.

To clarify: dbpa doesn't crack audio-cd protection. What it can do is disable autoplay, which is how the irresponsible music companies are able to automatically install software onto your machine with (or without) your permission, and one of the side effects of some of this software is to automatically prevent you from ripping the CD then (or at any later time, since the software monitors your computer for the registered CDs from that point forward.

You can do this yourself without dbpa (by holding down shift before, during and for 30 seconds after inserting a CD). That tells windows not to blindly run software found on the CD.

Anyone who knows that and still calls that cracking is a silly person! :)

Tell that to the company that sued the one uni researcher that told people they could bypass one form of copy protection with the shift key. ;)

Very silly people, indeed.

but what can I use as an indication then to see if the tracks were ripped correctly? If dbpoweramp says 'secure' for each track, can I assume then everything is ripped correctly or do you always have to listen to the tracks after ripping a copy controlled CD to hear the difference in the music?

thx

secure means tracks ripped without errors during the rip process.

if those tracks are deliberately defective, then secure simply means that the bad tracks are ripped perfectly.

in other words, garbage in, garbage out.

if the tracks were not 'secure' that means that errors/problems happened during the rip process, in which case garbage in, garbage out still applies.

do you always have to listen to the tracks after ripping a copy controlled CD to hear the difference in the music?

short answer, Yes.
