Hmm. It's been a while since the last time I mounted an audio CD on a
computer (I have stereo systems and a portable DVD player for that), but
as I recall, whenever I did, the tracks simply showed up as .aiff files.
And on the rare occasions when I've actually needed to convert them for
some other purpose (scoring a video, or creating a ringtone for my
cellular phone), I was always able to find something to do it.
As to going the other way, I have a CD-R machine in my stereo system for
that, along with plenty of blanks that are coded to work in it. Along
with various CD-burning software.
