It's not necessarily remedial, I had also wondered how much audio data
really means how many bits.  Among other things, I wouldn't want to be
62 bytes oversize and only discover it when I've made a coaster out of
some nice bizcard sized blank.  I also wondered all that time ago when I
got started, about the real size of my blanks, and -atip is of course 
the right answer to that.

Roxio has an excellent description of the breakdown:
