Hello all

This is a question for computer rather than hi-fi enthusiasts.

I want to copy individual tracks for safekeeping from audio CDs onto my
hard disk,
and then copy selected tracks from there onto my own CDs.

What are the methods, formats, etc available
The names MP3, WAV, AAC don't mean much to me.
Can someone explain the advantages / drawbacks ?

What is the best
a) to ensure quality rather than space-saving ?
b) more with space-saving in mind ?

Best regards, from Ray
