Computers do not read CDs according to the RedBook standard. They 'extract' the data. Once upon a time it was a big deal, now all the drives have it built into their firmware to all extraction automagically. The RedBook is not designed with computer processing in mind. when it was invented, CPUs were expensive. There is a fair amount of data correction in the spec with the data permuted to be resistant to some kinds of errors and ECC to fix some classes of error. The Redbook spec tells how to fake out music to cover dropouts so that most people can't tell. This is not what computer extraction is about. -- Pat http://www.pfarrell.com/music/slimserver/slimsoftware.html _______________________________________________ ripping mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/ripping
