Cdparanoia does not modify the data as handed back by the CDROM drive (and the
CDROM drive would not be undoing preemphasis). Preemphasis removal is not part
of my cdparanoia mandate; I have enough other CDROM quirks left to solve before
I could move on to such things.
(Note that currently cdparanoia also does not look for preemphasis in subQ. It
only checks the TOC and reports that).

I'm not sure how many MPEG encoders/decoders know how to deal with preemphasis.
I'd guess that the most reliable way to do it is have a util like sox (or a
feature in the encoder) to remove preemphasis and only encode mp3s with no
preemphasis. CDs with preemphasis are somewhat rare (and preemphasis was a
hack to begin with...)
