Re: digital errors?

["Mr. Tough" <electricfriends@hotmail.com>]

When you made multiple copies of the CD, did you create them all from your 
hard drive? Or did you create a 'master' CD and then copy them from that?

I have Adaptec Easy CD Creator. I also have a program called CD Copier 
deluxe. Sometimes the latter program produces the errors that you 
described, 
so instead, I use Easy CD Creator for copying. I just pull the tracks from 
drive D (my CD rom) instead of my hard drive.

Sometimes you can get that kind of digital error if you have the incorrect 
file types. My CD's come from .wav files on my hard drive and turn into 
.cda 
files on my CD's. A friend had problems when the CD burning program turned 
the .wav files into some different file type. Sorry, but I don't know much 
more about this.

Sometimes bad processing programs can produce these errors too. Try a 
before 
& after listen when running tracks through normalizers, noise reducers, or 
clip correction programs.

You're right, when you're copying CD's, duplicates should sound exactly 
like 
the master, regardless of the quality of the CDR. You might want to make 
sure your CD copying program isn't trying to "correct" the audio between 
CD1 
and CD2(by running a normalizer or something). CDR quality supposedly 
reflects 2 aspects: 1) How long the CD lasts, since CDR's are made with 
organic burnable material. 2)The percentage of CD's that are 'duds', or 
aren't recordable at all. I've been using the cheapest CD's with impunity. 
Who knows if my masters are going to degrade in 2 years or 10 years 
though. 
(Anyone know how long CDR's are supposed to last?)
