Hi all. I have downloaded Mtallica black album from internet in lossless format, and I´ve burn it in EAC with all read and write offset corrected and I overwrited lead-in and lead-out. But AR doesn´t recognise this CD when I try to rip it. I have compare the Original downloaded wav file with one ripped from the burned CD, and the wav is the same (Without error). Why AR doesn´t recognize it?? I guess that i t doesn´t recognize because the downloaded album is not a perfect RIP, Am I wrong?
Thanks

(Once I have burned the CD I use AR because I want to know if that album downloaded from the internet is the same that AR has in his Database)
Thanks and sorry for my english, I´m Spanish.

Ripping burned CD and them then appearing in AR has never worked, to my knowledge. One problem, of many, resides in the fact that the original CD drive that ripped the songs applies its offset to the first track and then when the CD is burned, this is not compensated for. You would have to know the CD the file was originally ripped from to have a hope of getting this right.

But when I opened the log file included in the download file I saw that reading offset correction is applied. Theoretically there isn´t any error from the original ripping (all the song were accuratelly ripped). And if I´ve applied correctly my drive´s offset, where could be the mistake?
Thanks for answering.

And how do you know that the person that ripped it, ripped it with the correct offset?

The downloaded file has a log, in which I saw that the person applied the correct offset of her drive.
Do you mean that he could be wrong or he modified the log? If so, You are absolutely right.
Anyway, if the person that ripped the original CD has ripped it well, I would have a perfect copy, without error, right? (Assuming that when I burn the downloaded file, I applied offset correction and ussing overwritting lead-in and lead-out)

Post the log.

Another problem might be that since your offset and their offset are different, especially if their offset is large and yours is small, then you are missing audio data which would result in the disc having different checksums.

That is the log. I have colorized some areas that I think that are suspicious in this log. Could be that the reason? If so, What do I expect from the log to have a perfect copy? Thanks again, and sorry for the delay. :smile2:

1. Only the first track has the pre-length gap listed. It looks like the ripper did not calculate gaps. Each track in the log should look like:


Track 3
Filename D:\MR\Al Stewart - The Best Of Al Stewart- Songs From The Radio\03 - Delia's Gone.wav

Pre-gap length 0:00:00.53

Peak level 97.6 %
Test CRC 7E7101E0
Copy CRC 7E7101E0
Copy OK

2. Do you have a cue file? To burn a precise duplicate you need to use the detailed pre and post gap information in the cue file.


TRACK 03 AUDIO
TITLE "03 - Delia's Gone"
PERFORMER "Al Stewart"
INDEX 00 04:16:10
FILE "03 - Delia's Gone.wav" WAVE
INDEX 01 00:00:00

3. Without the above gap info (the INDEX numbers) you can still burn an exact duplicate of the music, which is the most important thing after all. But you cannot burn an exact duplicate of the disc. Keep in mind that even different pressings of the same disc usually result in different Accuraterip checksums.

EAC extraction logfile from 25. November 2006, 20:36 for CD
<SNIP>

Drive offsets and gaps have nothing to do with disc identification.
If the CD was extracted correctly and burned with the appropriate cue file then it will be recognized by Accuraterip assuming of course that it is in the database.

If it is in the database but not ripped and burned with the correct drive offsets Accuraterip will report the rip as a “different pressing”.

Might it be that the log file is from a ripping of the Amelie soundtrack and not Metallica's black album which was the album you said you downloaded?

Yes, you are right but it doesn´t matter. I have the same problems with both albums. I have been researching those days and the problem is the cue sheet, as you said. The only way to have a perfect bit per bit copy of an original disc is making a cue sheet and not splitting the wav file (and detecting previously the gaps). It seems that if I split the wav file (with medieval CUEsplitter for example) some information is lost. Thanks to all for helping me. :thumbup::thumbup:
