    I don't know if it just records louder than the original CD or if it actually isn't a "perfect" recording and for some reason it sounds more harsh. Anyone else ever notice that?

    Steve,
    You're answer is too much gain and compression create a harsh listening experience. :D

    Can you describe how you copy a CD? (on a computer? what program? what settings?)

    An associate here says that if you don't extract a clone and simply record an "analog" copy of the music through your computer's sound card, it would definitely degrade the sound.

    The only things I found harsh were playing HDCDs on a conventional player & any CD/CDR in the recorder bay. OTOH, I do use CD mats to record CDRs. One on the CD & another on the blank. Also, I blacken the blank's edge. I find green may be sufficient for a CD, but insuficient for burning. I've yet to try temporary black just for burning but that may be an option for green lovers.

    Camarillo, would copying a CD by "clone" be the same thing as copying a CD by "image"? I have not noticed any problems by imaging a CD.

    (Yes, Dave, it's *finally* all done - gotta get an envelope to send it to you in! I've made disc images of the MFSL CD "I Robot" and DCC's CD of "Hotel Calif." for testing purposes.) :)

    When they get there, let me know what you think of the "image" CD!

    Theoretically, making a disc image should be a clone. I've never made a disc image for an audio CD before, but for CD-ROM's, it's pretty much an exact match.

    The only downside I've had with making disc images (and this is still just CD-ROM's) is if there is some sort of damage to the disc, like a scratch, the resulting image will have errors on it. I don't know if it will correct any errors it may read from a damaged audio CD, but it should say if there are any (and even if it doesn't, it should be easy to hear them).

    Well there are two ways to make CDRs on my computer. The first is from the CDROM drive directly to the CDR drive. The second is make a disc image from the CDROM drive to the hard drive and then take / copy the image from the hard drive to the CDR drive.

    I've been told (never really compared the two) that the second way (image) creates an exact image and there is no difference between the two CDs.

    The first way - there is a degrade factor in effect. Maybe this is the explanation you are looking for? See if you can get a CD made from a hard drive image - not direct copying from CD to CDR drive. Will you post the results?

    This was argued about in the old board with no real concenus. Then the computer gurus got into various arguments and discussions about copying programs. Made no sense to me at all! I just know where the power button is! ;)

    The excessive limiting/compression used on many modern CDs do indeed make them tiersome to listen to.

    For those of you who want to use a great audio disc copying program, go here.

    What you do, is basically image your CD to your hard drive with a .wav and .cue file. What's great about this program, is with good CD drives, it will image the whole disc, track stops and starts. You can use CDDB (so you can use CD-Text for those of you with capable players) and the program also reports problems with the image as and after it's made it to the hard drive.

    While those of you might like "one button", we all know life doesn't work that way, yet alone CD audio. Also, it becomes quite annoying to know that when your CDrom drive has errors, if you're going direct-to-CDR, the errors get burned in too.

    The good thing about this program is that it does NOT install, you just run it from a folder. Choose to run it in burst mode. for most jobs. Read the documentation on the site on how to use the program to its potential, but really, it's very easy, and a lot less busy than Roxio, Nero and other programs that manipulate the original data quite often.

    The program, as well as other CDR programs will not work on Windows XP unless you use the "force ASPI layer" hacks. If you do, everything works great.

    I won't bore you with how-to's. Inivestigate for yourself. This is the only way to duplicate audio CDRs for human consumption, fellas. Period.

    It also has a CDR burn program built in, some other tools, but Exact Audio Copy is mainly Alt+F7, make it to the HD, and then use either the built in burn program or CDRwin.

    Most of you with CDR drives who make CDRs quite often need to learn this. You will become much more in control. Don't fool with the other garbage, please.

    Oh, and the program isn't shareware, rather freeware with hopes that you send the gent a postcard saying "Hey, I like your code, you is the ****!"

    Fair enough?

    Wow, Sckott! That is pretty amazing software. I was just thinking about some of the very issues that EAC addresses and then you post this URL-- You da MAN!

    Thanks Sckott for mentioning EAC here. It's the recommended way (at least for PC users) of extracting audio in trading/tree circles. There is also a mailing list where users and EAC author Andre Wiethoff discuss the program and answer questions. Andre also takes suggestions and has included features that users have requested.
    What sold me on EAC early on was the trouble I had extracting the last track on a disc using EAC. It kept reporting errors and was taking forever. ECDC had no problem extracting the track and I was curious why. I examined the disc and there was a fingerprint near the edge. I cleaned the disc and then EAC extracted fine. That told me that ECDC was ignoring the errors when it was extracting and very possibly giving me less than an exact copy.

    That shouldn't make a difference in sound. If you use your CD-ROM for extraction in both cases, it won't matter. The only problem with burning direct from CD-ROM to CD-R is that you're a lot more likely to get buffer underrun errors. But the sound itself (assuming it does burn correctly) won't change.

    Hey Luke, do you always DAE before a burn on the Mac? If so, what do you use for DAE? The goofy thing included with Jam/Toast?

    I'd assume you mean do I rip to my hard drive first, and the answer is yes.

    Astarte CD-COPY. Actually saves the pauses, unlike TAE...
