Two questions about EAC rip AccurateRip verify
I was wondering if someone could explain this rip? It seems to rip fine but doesn't match anything in the AccurateRip database when verifying it with CUETools. I tried it on a few drives and there's no errors when ripping with EAC. Is it saying there's not a single submission that matches the CD in the AccurateRip database? Did I rip it incorrectly or missing something?

Also a second non-related question I noticed in the EAC log file that I see this "error" where it prints the ...has been confirmed... message twice in the log randomly but regularly. It seems to happen when the PC sleeps. Often I start a CD and walk away. When I come back I hit the space bar, click ok and that's whats in the log file. It doesn't seem to affect anything but I was just curious if after it wakes up it's a snafu that it goes online and verifies the rip again or something along those lines?

The pressing of the CD you have may not be in the AR database yet. Your rip is likely fine.
There is a limit to the offset that CUETools can check for alternate pressings. An alternate pressing of your CD could be in the AR database but out of range for CUETools to show.

The second question has been asked before but I can't say why it is happening.

Thanks Korth, I know you answered some other questions I had when I started this last November. You mean for example CUETools can check for a 2700 sample maximum offset but the CD is offset by 2800 samples or something like that?

Quote
An alternate pressing of your CD could be in the AR database but out of range for CUETools to show.

Is this similar to above meaning it's just out of the max range offset tested? Is sample offset based on a zero offset CD? Out of curiousity how is the zero offset CD determined, the first CD entered in the database?

Looking at the jacket it shows the copyright and print year to be 1999. It's 18 years old and it doesn't look like a new pressing. Does that mean, if I understand it correctly, it is outside the max offset tested it should never be able to be verified with CUETools?

Is it possible, with enough entries, eventually it will be with AccurateRip or is EAC with AccurateRip based on the same limitation of CUETools with a max offset checked/tested?

I did find that thread and saw it was asked but didn't see the answer. I appreciate it Korth. I didn't think it was a big deal by no means as CUETools shows them as being fine but worth asking. It does seem to be somehow related to when the PC sleeps/wakes though.

Something like that.

It was a continuation of the above.

The read offset correction is to make sure each rip starts reading the CD from at the same point (you could call that point zero). For each release or pressing, the actual audio may start playing at a different position. If the audio is identical but starts at different positions then one release or pressing is offset from the other. Zero would be the rip of the CD you have and the offset would be the other one found in the AR database. Each offset, release or pressing with the same layout are grouped separately by CRC match and stored side by side by side under the same ID in the AR database. To keep it simple, CUETools tests your rip at different offsets for matches in each group.

When they repress a CD that doesn't mean the label or packaging has to change.

Once your rip is submitted to the AR database, there will be at least one pending entry for each track of your pressing (and would get stored along side of the others). Future submissions could follow.

Ok, I think I understand and I do appreciate your patience. That completely changes my reference point of view. I didn't know the CD being ripped was the zero offset. I am still missing a piece (probably several of the big picture). So when it can't be verified it's saying I found a matching layout but no matching offset. Using the example above of the Detroit Rock City soundtrack it shows only one offset and it's not my matching offset, so what is that one? It's roughly 80 submissions (00+00/80) of AR1 and AR2 of only one offset?

It seems every rip has a zero offset whether it matches something or not. I guess the part I don't understand is when it's not matching like above. It's saying it's a matching layout but all the CRC's are incorrect?

Ah, that makes sense. I wondered about that. It seems some CD's that seem to old for the ISRC information are suddenly filled in, I think.

Yes but that doesn't mean there's anything wrong with your rip. As it states in the EAC extraction logfile, "You may have a different pressing from the one(s) in the database"

Note: This is just for fun to demonstrate. You won't need to do this again as it doesn't give accurate results.
For fun, if you want to see if there are other results just out of CUETools' range you could put a high value in the 'offset' box of CUETools and Verify (verify won't change the audio in your files). Try 2900 then -2900. Other results may show up or have matches but the first or last track may NOT have a match because you'll be shifting the audio further than the number of samples AR ignores. Make sure you set the 'offset' box back to zero when you're done playing.

Hey Korth this was interesting and helped a lot. Shifting -2900 yielded no change (except the peak range shows it's off every time) but shifting +2900 I received 2 hits. Even more interesting (or not ;)) is all tracks were verified as accurate with an offset of like 1482 and 2353 (something close to those numbers). Can you keep shifting the offset until it's zero?

So if I can take another stab at it. The pressing I have is now entered into the AR database but it will be "queued off to the side" until at least one more(?) pressing is entered/uploaded that matches?

CUETools really has nothing to do with the AR database or does it? I am still struggling with the CUETools offset range used for testing. If let's say for example that same pressing all of the sudden has 25 entries in the database and can be AR verified would CUETools use that new offset pressing as a valid range for testing for lack of better words? If not it would never be verifiable with CUETools as it sits. I mean does CUETools know there are say for example 5 different offsets for a particular pressing and will test a range around all 5 offset pressings or only one range that covers the largest portion of offsets? I guess what I am asking if what is the criteria for the CUETools range offset if that makes sense?

1) 2900+1482=4382

2) It will likely be placed in limbo until confirmed by another rip.

Read the track CRC records (multiple CRCs from different pressings are saved in the same file, walk the list until one matches)

Advanced Usage: Offset finding CRC

The offset CRC is a drive offset finding CRC, it is an AccurateRip CRC calculation 450 frames in and is calculated with one frames data. This can be used when offset adjusted for the drive to find the matching CRCs of other possible pressings, finding their offset. When the offset of a pressing is known an additional CRC can be calculated using data which is offsetted by the pressing amount (using data from the adjacent tracks). The maximum offset can be +-5 frames, otherwise the first or last track would fail to verify against the pressing.
5 frames = 2940 samples

Korth, I truly appreciate all the help in understanding the process and how it works a little better. You sir are a scholar and a gentlemen and I do hope you have a wonderful weekend. Thank you. :)
