I used EAC to rip a scratched CD, CUETools to repair it, and have some questions about the information contained in the log files.
One of the ripped tracks had errors. Here is an excerpt from the EAC log file:
Track 3
Filename D:\Music\Agnus Dei\EAC WAV rip\03 - Missa Papae Marcelli- Kyrie.wav
Suspicious position 0:03:49 - 0:04:00
Suspicious position 0:04:12 - 0:04:15
Peak level 53.7 %
Extraction speed 0.5 X
Track quality 95.6 %
Copy CRC 19B0A8D4
Cannot be verified as accurate (confidence 86) [74FB864A], AccurateRip returned [CAB8C6DE] (AR v2)
Copy finished
Question: does "confidence 86" mean this track has been ripped and reported by 86 other people to the CUETools Database?
The CUETools plugin report section of the EAC log file says the following:
---- CUETools DB Plugin V2.1.6
[CTDB TOCID: d5HwBKwowk4Nt1TvLjTIVWSUdww-] found
Submit result: d5HwBKwowk4Nt1TvLjTIVWSUdww- has been submitted
Track | CTDB Status
1 | (211/460) Accurately ripped
2 | (215/460) Accurately ripped
3 | (182/460) Differs in 14737 samples @03:49:08-03:49:50,03:50:02-03:50:72,03:51:23-03:51:52,03:52:04-04:01:05,04:12:38,04:13:32-04:13:46,04:14:54
Question 1: What are the 2 numbers in the "CTDB Status" column?
Question 2: The CUETools analysis is apparently able to determine that the above ripped track differs from the "reference" by 14737 samples. What is the maximum number of different samples that can be detected? I assume the CTDB doesn't contain *all* samples for a track, as that would simply allow someone to download all samples and create the file without owning an original copy, which would be a copyright violation. Is that correct?
After seeing the EAC report, I was able to repair the incorrect track above using CUETools (instructions taken from tij's post in this thread: https://yabb.jriver.com/interact/index.php?topic=122218.0). When I reviewed that log file, I found the following:

What do the ( 1/461) and (182/461) mean, and why are two sets of numbers reported here whereas EAC only reported one set (182/460)?
Then there is this section of the CUETools log file:

What exactly is going on here? It looks like CUETools is trying a lot of different offsets to all tracks to see if one particular offset causes all tracks to match the "consensus" found in the CTDB. Is that correct?
