None. The audio is extracted [via a ripper like cdparanoia] from the CD
directly to a file on your disk, it never crosses the sound card. The mp3
encoder (something like blade enc 8hz-mp3, et al) reads that data (usualy
raw wav data) and encodes it (compresses it, loosing some of the quality)
into mp3 format.

64bit is better quality than my ear can detect. If I were to listen
to a 5 second clip from a CD, and then hear the same 5 second clip from
an mp3, I could tell the differnce, but while just listening to the mp3,
the quality isn't usualy an issue for most music -- some classical might
show more of the degradation.

Actualy I think that this is the same set of issues regardless of the
operating system you use to either rip the audio data, or compress it
into an mp3.
