By design a bit perfect copy is not guaranteed.
This is inherent to the CD audio standard (Redbook).
At design time, they decided to maximize capacity at the expense of bit perfect reading.
An audio CD uses all 2352 bytes per block for sound samples.
A CD-ROM (bit perfect reading guaranteed) only 2048 bytes. The remainder is used for error correction code.
A 15% reduction in capacity compared with the audio CD.
So most of the time the rip will be right as CD's are pretty reliable.
Occasionally is will be wrong and that is where dBpoweramp comes in.
Instead of interpolating will will try to re-read troublesome sectors.
As bit perfect reading is not guaranteed, that is where AccurateRip comes in. If your rip matches those of others, it is likely a correct rip.
