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.
