Even if it is a rare CD with only 1 entry in the database, if it matches the likelihood is extremely high that the rip is accurate - because the chances that the rip in the database, using different hardware and probably different software, made with a different individual disc, had the exact same errors, down to the bit level, are astronomically small. If the rip exactly matches the database, that provides an added level of confidence that the rip is accurate. But then, the secure rippers check with the AccurateRip database. Of course that method is not foolproof by itself. Because the vast majority of ripping errors do not repeat themselves in an identical manner, getting multiple consecutive identical ripping results is, already by itself, a strong indicator that the rip is accurate. The fact is that secure CD ripping like that done by XLD and DBPoweramp, combined with AccurateRip database checking, provides a result that is not statistically 100% guaranteed, but is sufficiently close to 100% that it is not worth worrying about for anyone who - like the OP - is looking for a method that also is easy and convenient.Īs you know, the secure rippers do multiple passes on the disc and they don't move on until they get identical results on more than one pass.

He asked about a method, a workflow, not about scientific or statistical experiments. He asked about the 'best way' to rip CDs to a Mac. The OP did not ask about how to ensure theoretical or statistically certain 100% accurate rips all the time. However, I believe it is you who are missing the point here. I appreciate the info you are providing at your linked page, and I understand the point you are making.
