I'm not so sure about this - cliveb mentioned he obtained identical SPDIF bitstreams from an original CD and a CDR copy, which means there was zero interpolation in both cases. Also in my own CD ripping I often get perfect rips at 5x speeds or so - so again, no uncorrectable errors. Of course I don't know how many correctable errors there were, so it's hard to compare. Another point is that without redundancy (which by the way for CDs is 33% - one error checking byte for every three data bytes), it would be difficult to know if there had been an error at all - that's part of the purpose. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=24957 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
