Here's a great article on why computer audio potentially gives the sonic "who's your daddy" to CDs. Steve Nugent of Empirical Audio, maker of the Off-Ramp and Freeway USB transports we covered earlier, explains why jitter (the little picture) makes CDs ultimately inferior. If you've ever wondered why a medium based on 1s and 0s has so many problems then this article is for you.
Computer Audio Takes Aim at CDs
by Josh Ray on December 02 '05
Simply, CDs not only contain the music information, but also the way the music should be played back. Jitter messes with the timing of the playback, causing all kinds of smearing and other nastiness. Jitter happens when the laser reads the CD as well as in the various digital to analog conversion processes that happen along the way.
Computer ripper programs like iTunes take the music off the CDs and bypass the jitter issues, extracting the information in multiple passes to make sure it all matches up correctly. Hard drives access the information in a much cleaner fashion and computer handling of the music is potentially vastly superior over traditional CD transports.
