what does the number represent after accurate rip in parenthesis

[len bell]

when i rip a track flac uncompressed, after ripping i see accurate(30) or accurate(2), etc...what does the number represent in parenthesis, and does that have anything to do with rip quality, and if so is there an audible difference.

Thanks,

Nothing to do with rip or sound quality. It tells you how many other people in the world ripped the same disk and had the same CRC (i.e., bitperfect match). That's the advantage of accuraterip over simply secure ripping. If you rip the same disk more than once and get matches, there could still (although unlikely) be problems because you are using the SAME disk, SAME diskdrive, etc. But with ACCURATERIP, if you get a match, your rip matches x number of other people ripping a DIFFERENT physical copy of the CD on a different computer with a different disk drive. The odds of you matching their rip when there is a problem is probably trillions to 1 (i.e., effectively impossible).

Having larger numbers (2) vs (30) is not that big a deal. Just means more people have ripped that disk. But even a (1) match is assurance that your rip is bitperfect** (assuming that the single match is not a rip you yourself did in the past that is now in the AR database and therefore you are only matching to yourself).

**EDIT: For example, this AR match of (1) is equivalent to you buying TWO copies of the CD, ripping each of them on DIFFERENT computers, and then comparing the CRCs of the two ripped albums and getting a perfect match. Also note that new CDs (and even slightly obscure older CDs) don't show up in the AR database. Not showing up doesn't mean there is a problem, it is just not there (yet). One can use several tools to check back on AR matches at a future date (useful for new CDs). One is PerfectTunes available here.

garym Thank you for this explanation! I just ripped a cd that is AR (1). This led me to wonder if in this situation ultra-secure would get me closer to being bitperfect. Based on everything I have read along with your comment from 2013, it sounds as though AR (1) is still closer to bitperfect than an ultra-secure rip since AR (1) indicates that there's a match despite two separate CDs being ripped on different computers using different drives. Do I understand that correctly?

Correct. The only issue with AR(1) is if you ripped that same CD before on the same machine/drive and submitted that result to the AR database. In that case, the AR(1) is a match back to your earlier submission. But without this, AR(1) is a great outcome. The odds of that AR(1) not being a perfect rip are about the same as me winning the $1 billion lottery once a month.
