Depends on the speed of the MP3. MP3 at 192K upward is pretty good. Hard =

tell it from a real CD. But as a general principle I'd minimize the =

lossy
formats like mp3 and stick to .wav so much the better. MP3 and other
compressed formats can make a right dogs dinner of a recording that has =

Not so -> .wav is the windows default audio format and .aiff is the Mac =
one.
Actual audio CD's, as opposed to data CD's, have neither .wav or .aiff =
on
them. I forget the ISO standard number that actually defines the layout =
of
an audio CD, but its nothing like and pre-dates data CD's.
