Questions About CTDB Plugin in EAC, Does it work alongside the AccurateRip database?

With the CTDB plugin installed and enabled, does EAC check both CTDB and AccurateRip after a rip, or does it only check one database? Is there a way to get EAC to check both? (Though as I understand it, one match in any database should be enough verification as long as it is not a previous submission from when you ripped the same CD in the past.)

After I ripped one of my tracks, the EAC log says "Accurately ripped (confidence 5) [6489E204] (AR v2)".
I assume "AR v2" is AccurateRip, but how will I know whether CTDB has been checked?

If CTDB finds an error, will I be prompted to use its error-correction feature, or do I have to do something manually in EAC?

Thanks.

Thanks for looking into that for me. I just want to make sure I understand what you said about the pregap. Is the only difference (or only apparent difference) between my rip and the previous rip simply in the way EAC appended the gaps, and there just aren't any other records yet for people who ripped the same album and handled the gaps the same way as I did? That would make sense, because I have EAC set to append gaps at the end of the previous track, so the missing gap at the beginning of the first track would explain the difference between my rip and the other record.

To clarify things for me: do the "Start" and "End" columns in the database records refer to the positions on the CD where the ripped tracks begin/end?

Based on the understanding I explained above, I am confused about a few things. First: Why is the length of Track 1 the same in both records? Track 1 starts 32 frames later in my rip, which makes sense if the pregap was omitted, but why does it also end 32 frames later?
My initial explanation (which I now don't think is right) was that it is because the gap of the next track is appended on the end, adding to the length, and the gaps for all the tracks happen to be exactly 32 frames.

But that leads me to my next question: Why is the length of the last track the same in both records? Wouldn't the last track be shorter due to not having any gap appended to it? I expected the last track to end on the same frame in both records, regardless of how the gaps were appended.


BUT, to confuse me even more: I ended up reading this CD's cue sheet, and after reading this page ( http://wiki.hydrogenaudio.org/index.php?ti..._and_Cue_Sheets ) and learning how to interpret EAC cue sheets, I came to believe that this particular CD actually has NO gaps except for the pregap in Track 1. In the cue sheet: the first track has a "PREGAP 00:00:32" line which would cause silence to be written for 32 frames to account for the missing Track 1 pregap, but none of the other tracks have any "PREGAP" or "INDEX 00" lines, which I interpret to mean they just didn't have any gaps on the CD.


This raises a couple more questions:

-- So we know that my rip starts 32 frames later due to the omitted pregap; but how is it possible that all of the tracks other than Track 1 start and end on different frames if there really are no gaps between any of the tracks? Is there something technical about the way CTDB works that I'm not aware of?

-- If none of them had any gaps to speak of, why weren't all the tracks other than Track 1 "Accurately ripped"? And some of them were "Accurately ripped", so.... is it possible that the other guy actually had a bunch of badly ripped tracks? Mine were all verified by AccurateRip.


(....Or, from an entirely different angle: Could the difference between the two rips have something to do with the fact that I didn't configure EAC to overread into the lead-in and lead-out? My drive is supposedly only 6 frames off, though, not 32.)


Oy. Sorry to ask a bunch of possibly dumb questions. Thanks, korth, for your very informative help thus far.
