But there are digital sources other than RedBook CD?
DAT, MO, ...
To my way of thinking DAT and MO were formats/media
were *designed* to be recovered digitally whereas audio
CD (as contrasted with CD-ROM) was never designed to
be used to reproduce the exact digital sample stream. The
minimalist error detection/recovery methodology used in
the RedBook format would appear to support this theory.
Which "minimalist error detection/recovery methodology" would
that be. Red bnook audio CD's use several rather sophisticated
error encoding/detection and recovery algorithms, including EFM
encoding, CIRC (Cross-Interleaved Reed-SOlomon Coding), etc..
Typically, the raw bit error rate on a CD is on the order of 1
bit in 10^5 or 10^6, but after CIRC error correction, this is
reduced to 1 bit in 10^11 or less. I have routinely seen discs
play the entire way through without a single uncorrected error.
