What's the best free Unix tool[0] for doing this?
Sure, I know about dd and
cdparanoia, but those only extract data and CDDA respectively, and I'd
prefer produce an actual image complete with TOC, subchannels, etc. To *use* the
data, I can always transcode from that into something lossier such as FLAC :) but
the reverse transformation is not possible.
My (possibly superficial and incomplete) understanding was that the
best process for exact duplication of mixed-type CD-ROMs is to rip the
data/audio portions separately using programs best suited for those
tasks, and then have a "cue" file that describes how to recreate the
TOC of the original disc.
You already mentioned cdparanoia, which can give you the raw PCM for
audio tracks -- but I did want to add that I've had good luck
preserving data tracks with "ddrescue", which is essentially "dd"
with
much better error handling, including the ability to map out which
sectors were recovered successfully and which are missing (and
sophisticated read retrying).
I don't know of any free tool that wraps all of this up into a single
package, however.
