For JeanLuc:
I think that jitter correction is that CDex reads several sectors overlap to the left and to the right. This is to avoid to lose or to repeat some sector.
But I think that jitter problems are easy to appear if you are using other programs (Word, Internet Explorer, Kazaa) at the same time. If you don't use the pc while you rip, there wouldn't must be jitter problems (that is clics in the resultant wav).
Correct me if you don't think than me.
That what is often falsely being referred to as "jitter correction" ...
In fact, this is nothing more than buffered burst mode with overlapped reading (you can adjust the amount of sectors being overlapped) and resync to avoid losing data ...
A sync error will then be reported if the overlapped area does not match (or cannot be aligned properly) for some reason. This option is valid (and thus should be used) with drives that are not capable of delivering an "accurate stream" of audio ... a normal ripper will not benefit that much from using sector-synchronization except for the overlapped area.
"non-accurate" in this sense means that the drive shows inconsistant read offsets over the disc area (which modern drives don't do anymore - with the exception that they get worn out and become non-accurate - my old and now replaced PX-40 showed that kind of behaviour at the end of its "life").
Higher system load during DAE does not cause jitter problems (as stated on the Feurio! homepage which is not entirely correct) since high system load cannot influence hardware specifications ... these problems should be better referred to as "timing problems" since they occur on the IDE/PCI bus and not within the drive ... and timing problems can occur with sector resync as well.
So, summing up you can
1. deactivate sector resync (aka jitter correction) if you own a modern drive
2. use higher rip speeds and keep your system load low
3. rip twice with any given DAE tool (there is a multitude out there)
4. compare the two rips afterwards (aka "Test & Copy" in EAC)
5. be very sure that your rip is free of random & burst errors if both rips match.
