If those rates are per bit, 10^{-11} would be something like one single

that single bit errors will be totally inaudible.

Yes, I have seen this discussed elsewhere as well.
I thought the OP's question was a good one - how to get those bits off
the CD onto the the HD with the minimum of errors. I suspect the answer
is mainly about using EAC or equivalent because getting the bits off the

I'd like to point out why extracting audio data from RedBook CDs is

Timothy - toally agree and what you call DAE jitter was certainly a
problem in the early days of digital audio extraction (early 90's)
using CD rom drives.
However, AccurateRip results from a vast user/disc population are
showing high consistency in extract processes, so I'd go out on a limb

I could go further and suggest (flameproof suit on) that ripping is more
accurate than reading a red book cd using the old fashioned (spiral
tracing, one bite of the cherry) method.
In fact aren't most CD players these days actually using some form of

You've got a common terminology problem.
You don't use a codec to pull data off an audio CD.
I ask this because a friend in the hi-fi, home theatre and studio
equipment manufacturing and design business seemed a little skeptical
about the results of burning CDs to a hard drive on a computer and
ending up with a high fidelity result. He has the experiential and

Use the program Exact Audio Copy (EAC) in secure mode. The USB
interface will not affect the bits from the CD to the hard drive.
What you thinking about is a USB sound card. USB nomally does not use
any flow control with USB audio output, therefore the computer
