View Full Version : Music Cd copies creating tons of noise in signal, guess its not a copy
01-25-2003, 10:50 AM
i have been copying music cd's from people for quite some time and, as far as i thought , there was a direct copy of ones and zeros, scratches aside , to the copied cd, so in essence there would be no difference in the sound quality of the original and the copied cd since its just data, but when i took music cd's which i copied and work without error and played them on the Hifi system of that belongs to this girls dad i know, there was a ton of static on the cd-r copies, the oringinal cd's worked great, but any burned cd had a ton of noise in the signal which could be minimized by drowning out the high frequency band, so if anyone could shed a little light on this issue, i didn't think the copy would mkae a difference since its just reading ones and zeros so how would this noise signal get into the cd, the interesting part is that it only shows up on really high quality sound systems, wehre the rest just miss out on it, all comments welcome, sinc. lurch

What method are you using to create your copied music CD's?
I usually convert the cda tracks on the CD to WAV files first, onto the HDD, then use Nero to burn them. Haven't experienced any problems so far, have played these CD's on systems costing in excess of £2000.00 (not mine :) ) and they sound OK.
For those CD's with multimedia on, I use Clone CD, haven't played these CD's on any top end systems though.
I use dbPower Amp for the cda to WAV conversion, seems OK to me.
My own system is a Kenwood 50W x 2 amp; Marantz CD player and KEF speakers, don't consider it top end, but it's not too shabby.

Here is a piece from another message board. It kinda stuck in my mind as I was of the same opinion as you.
I used to use the Ripper that came with EasyCD5 until I actually started to listen to the MP3 that I was encoding - They were, for more of a better word, crap. The program was encoding them at 128 but of a real bad quality. You can normally tell this by the way it semi-pans across both channels, and also by the quality of the sound of a cymbal.
From that it would appear, all Ripping and Recording software are not equal in reproducing quality sound.

All I can say is I have a high end sound system inside and a pretty stout one in my truck as well and I can't tell any difference between my masters and the copies I made for the truck.
I burned them using Nero and all I do is insert the master and a blank then I click on "copy" in the wizard. :)

Lurch, I usually convert the CD tracks into WAV files using MusicMatch, and then burn those WAV files. I haven't had a problem on a friend's $4,000 hi-fi setup...yet.

are all the CD-r's you tried that caused the problem the same brand - if so that could be where it lies

well i'll have to check, the program which i had used at the time was sony cdextreme, using disc copy, it took 5:30 to copy the whole cd on the fly, which is why i did not feel that tthere was anythin going on to change the data while i was copying it, as changes would slow the process, also the cd sounded perfect on my machine, but there was a distinct signal of noise produced when i listened to "No Doubt" newest album, which i got from her, with my copy of it right next to her original, cd brand is something i didn't think of, they are AT&T surplus cd's , but the part that struck me is that for a lower end sound system the noise is not reproduced, thx for all of the feedback, i'll do some more checking when i get a chance,

I don't convert formats for my backup music CDROMs. Most are *.cda format.
What I do is copy CD using Nero 5.5.x. The trick is NOT to copy the original nor the CD being written to very fast. My units can go as high as 48X, but I still keep the CDROM copies in the low single digets. The quality for our CDROM players is well worth the extra time which is usually not all that long anyway.
Nero 5.5.x select slow copy and write speeds. IF possible, I make the write speed about half the copy speed. Then select COPY CD and Nero does the job. :IAdj:

I do the same thing Nelda,I copied some yesterday at 4x,just to make sure they were as clear as the original,they were :D

Agreed, I usually copy upto 16X for good results..
Anything above 24X has 'damaged' sound.
