As you can see here some tracks are "(12/12) Accurately ripped" and some are "(11/12) Accurately ripped"
I am not sure what these numbers mean.

I also did a audio checker test:

I got an error occurred at track 6. I don't know why...

My questions would be:
- is 11/12 an accurate rip?
and
- if 11/12 is an accurate rip why does the audio checker report an error at track 6 ?
( i also used auCDtect test on the same files and again had an error at track 6 )

Thank you :D

Sounds like 11 out of 12 people produced identical rips to yours. And the CRC match means that everyone had the same ripping error on that track. Sounds like it was intentional.

Slightly off topic but shouldn't "Defeat audio cache: No" be set to yes?

I'm still learning about configuration myself so maybe your drive supports this.

Enabling the cache bypass makes ripping very slow. Secure ripping features are largely irrelevant when you can verify the output with AccurateRip. If you had a bad CD that failed to be ripped properly you could enable all re-read options and cache bypassings and try to get better results.

Thank you for clearing this up! I still do not understand why only track 6 had an "error" while other 11/12 tracks did not. I listened to the track itself and it is flawless to my ear.

To my surprise, my CD/DVD drive does not have that option, unlike most drives...

As my CD does not have "Defeat audio cache" feature does that mean that the ripped content is lesser quality? Could this be the reason I got an error at track 6 and no errors in EAC log?

What is it that you think audiochecker does?

Re: is 11/12 an accurate rip?

- if 11/12 is an accurate rip why does the audio checker report an error at track 6 ?
Because it tries to check file "06 - Slovo o covjeku.flac" while its real name is "06 - Slovo o čovjeku.flac".
Apparently it doesn't work well with non-ANSI characters.

I have no idea. I think it has got something to do with checking if data is cd quality.

- if 11/12 is an accurate rip why does the audio checker report an error at track 6 ?
Because it tries to check file "06 - Slovo o covjeku.flac" while its real name is "06 - Slovo o čovjeku.flac".

Very nice observation! This may be it!

I just changed č to c in the filename and there were no reported errors. I thought filename did not matter ::)

Incidentally, that CDDA probability checker is mostly useless, you can fool it by applying noise shaped dithering to the signal.
