Such a tool would have to 'know' how something is supposed to
sound, i.e. what the expected average spectrum should be, and
then decide if a file is too bright or not. Apart from that,
once the CD is converted to a file there is no other way. So
you'll have to listen.
Anyway rather few CDs will have pre-emphasis, it is mainly
a thing from the early days when many players were limited
to 14 bits.
