Inaccurate computer CD reading?


OK, here's something I never understood, so maybe somebody can enlighten me:

Why do people say that CD's ripped onto a computer using Exact Audio Copy sound better/more accurate than with other software?

How can a computer CD drive be inaccurate? After all, they are used for executable software that must be entirely bit-accurate or else the software may simply crash. Why would it be different for reading audio CD's?

I can give a little info here: First of all, even though both a Computer CD (CD-ROM) and a CD Player play Audio CD's- there is one big difference. The CD-ROM standard uses 'error-correction', as indeed just One misread Bit would 'crash' the program/data. The CD-ROM in your PC has extra electronics/logic to prevent this. You can consider your CD ROM drive 'backward-compatible' with 'RedBook' or Audio CD which came first.

So, therefore, if 1 or 2 bits are misread while just playing back music, you may not even hear the difference.

Nsgarch - so my guess is that when you burn at faster speeds, you may lose more bits, and therefore lose some fidelity. On the Linn website (in their FAQ's when asked whether Linn players can play CD-R, etc.) they talk about the loss of bits when burning a CD-R, but when I play a CD-R on my Linn Classik, I can't hear any 'loss' of fidelity.

Hope this helps.
