Pre-emphasis (during CD mastering) is essentially turning up the treble with a very specific EQ curve. There is a bit in the data stream from the CD that indicates it the treble has been so boosted when the disc was recorded so that the CD player can automatically apply the complementary treble cut when the disc is played back to restore the original sound. iTunes does this automatically when ripping such a disc so the resulting files will sound right. Exact Audio Copy does not, so I apply the treble cut to the WAV files using an audio editor program called Cool Edit.
Why do record companies occasionally go through and cause listeners all this potential hassle? Well, CD emphasis can reduce the already low hiss level of a CD a little bit further. Most popular recordings come nowhere near to utilizing the low hiss level CD is capable of, though, so very few producers bother with emphasis. -- Timothy Stockman ------------------------------------------------------------------------ Timothy Stockman's Profile: http://forums.slimdevices.com/member.php?userid=8867 View this thread: http://forums.slimdevices.com/showthread.php?t=43910 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
