Ripping Strategy
Ripping Strategy
OK , I finally dusted off my OmniGraffle skills and created the flowcharts illustrating how Rip's audio extraction engine works: http://sbooth.org/Rip/details.html

Re: Ripping Strategy
Thanks Stephen, this is interesting indeed. I am excited, the strategy seems to make sense to my naive thinking anyway
So, if I understand you correctly, you feel that this strategy is superior to a strategy that is based purely on AccurateRip??? Do you use cdparanoia anywhere in the new strategy, or is it entirely based on the new comparison ripper and Accurate Rip? I may be confusing things here, but set me straight if you would.
Thanks again, very excited to get ripping and testing!

Re: Ripping Strategy
There is no cdparanoia in Rip- I think that drives have come a long way since that code was written and that grinding away on individual sectors isn't the best way to go. In my testing (although only on 4 different drives) my strategy seems to be generally successful. So all the ripping code is my own.
Rip isn't 100% based on AccurateRip for two reasons:
Rip isn't 100% based on AccurateRip for two reasons:
- Not all discs are present in the AR database
- Some discs may contain errors that would prevent AR verification, but users may still want to extract the audio
Re: Ripping Strategy
No paranoia. Stephen is on record saying he questions the efficacy of paranoia's demands on drives.
Now, as to what the "engine" behind the comparison ripper is, well, I can't recall from the lengthy thread on secure ripping. I think it's pretty much a "Finder copy" relying on C2 error technology. The big thing here is AR, best I can tell.
C2 + AR + matching cheksums = secure rip?
Once things settle and initial Rip bugs are worked out perhaps then Stephen can take time to flesh out the chart for us.

Got it, thanks guys...I look forward to testing.
