First off, i'd like to say that CTDB is probably the most useful and amazing tool i've seen since i started doing DAE a few months ago. Thankyou so much for creating something that can repair bad rips or essentially .. damaged CDs.

I've started using the CTDB repair function and i'm absolutely loving it. I'm struggling with a certain feature of it right now though.

Some of the albums I want to repair are showing up in the CTDB but when I attempt to verify them, it says for example " AR: offset 112, rip not accurate (0/116), CTDB: could not be verified ".

Now this seems to be happening pretty much only for albums where the accuraterip log shows matches for multiple offsets and the CTDB repair function won't activate and encode my files because it doesnt know which offset to use. I tried telling cuetools what offset to use in order to force the encode, but it wouldnt do it. I tried fixing the offset of the files just incase that was causing it, but that wouldnt do it either. Now I know the repair function can only repair a certain amount of errors, but for these albums i dont think the error count would be that high. I think the CTDB just gets stuck when it doesnt know which offset to use..... which is weird, because if you look at the bold text above, cuetools + AR is able to figure out the right offset. Is there a way of telling the CTDB to use the offset that AR is seeing and then repairing the damaged tracks? This situation doesnt happen in all cases with multiple offsets, but just mostly when there is a large number of offsets or the confidence for track matches are quite similar for each of the offsets
Again, this DB is awsome. If you have the time to populate it with your verified albums then please do so, because everyone benefits in the end.

How so exactly?

Just like you said Greg uses AR2 to accept submission, so no AR no CTDB simply.
Without AR2 there would be no way to dismiss noise (scratched submission) from CTDB.

I think it would technically be possible to create an independent CTDB, by comparing submissions, but it would be hard for Gregory for no gain as AR already does that. To be short if Greg would have made CTDB independent he would have needed to reinvent the wheel ... the wheel being AR.

Edit:
You were faster:

Must there be a record in the AR database for something to be in the CT database?

Yes AR2 in AR database before being accepted in CTDB ... I learned something to Greynol ! unbelievable wink.gif

A confidence of one that vanished is really no better than a confidence of one that did not vanish, or any better than a confidence of two provided it was not your previous submission.

I am not sure that I get what you meant but a confidence of 2 no matter if one is your own "precious" submission is better than a confidence of 1 because a confidence of 1 is almost like no confidence at all for me ... as it can disapear. To trust AR1 you have to keep records of what you submitted to the database which is insane in the long time.
