cdparanoia rips slow. Period. That's the way things work. cdparanoia
always strives for a 'perfect' rip. That means that it will correct
errors when it can and only gives up on part of a CD when it is
impossible to read data from it. It also eliminates jitter. Depending
on how well manufactured (i.e., how cheap) your DVD-ROM drive is,
there might be a lot a jitter to correct. One option that I found when
I started using cdparanoia is an increase in speeds when I put my
DVD-ROM drive under IDE-SCSI emulation, as directed in the cdparanoia
documentation. My rip speeds went to 4x instead of 2x with zero jitter
or loss of quality.
Only use cdda2wav if you know your CDs are in perfect quality and don't
mind the occasional 'blemish' in the quality.
