That sounds quite a bit like pure nonsense. Perhaps the term "jitter correction" isn't exactly hard science?

What I can say: long reads are used, that are 2352 bytes per sector ( 98 frames * 24 bytes ), ignoring the extra sub-channel byte - which is pretty useless for CDDA, since the 96 bits [12 bytes] of subchannel Q (the only one defined by the standard ) give no extra information. Reading error statistics ( which might give some info about the disk quality ) isn't implemented.
