What is currently the best way to rip scratched audio cds under Linux?

What I find complicated, is that there are several tools available but it is not clear if one tool has better error correction features than the other.

I mean, there are at least:

  • cdparanoia
  • cdda2waw
  • cdrdao

cdparanoia is designed specifically to handle damaged media, with a wide variety of strategies ranging from re-reading sectors to interpolating lost data using FFT.

I've had the greatest success with cdparanoia over the various other unix tools I've tried. Note that the newness of the reader (both vintage and dirt/wear) makes a big difference. Now I'm looking for a ripper that can extract cleanly from music CDs that were in the car in the sun and have holes in the polycarbonate layer you can see daylight through ;) – msw Sep 26 '10 at 13:18

If you have holes in the disc, no ripper is going to give you a 100% extraction, the data is literally gone. – Casey Jun 6 '11 at 10:22

I use the windows freeware exactaudiocopy under wine, which has its emphasis exactly on error correction. This works very nicely (see its entry on winehq). If you want to stay natively you might want to have a look at rubyripper.

This does not really answer my question. A lot of projects claim they have 'emphasis on error correction'. But the question is: What tools are superior in doing error correction? And why? And btw, rubyripper looks like a frontend to cdparanoia. – maxschlepzig Sep 26 '10 at 10:39

Well, all I can say is that whenever the topic of error correcting ripping is discussed, exactaudiocopy is what people recommend. Whenever there is a possible uncorrected error, it will tell you the position in the file. That means you can check if those are corrected by an other program. – fschmitt Sep 26 '10 at 11:17
fschmidt, is absolutely correct EAC is the best tool for ripping CD's. I used to use it on Windows all the time. I haven't had to rip anything on Linux recently, but when the time came I was going to try EAC under wine, and if that did not work, would have added it to an XP VM. – HandyGandy Sep 26 '10 at 21:21
@HandyGandy Could you add some reasoning why EAC in your opinion would be superior to e.g. cdparanoia? – maxschlepzig Sep 27 '10 at 10:18
@max What do you want me to say? That it use the superior Ghirkov-Schmidt reduction algorithm to do it's error correcting. so it works well? Well I can't do that. I can only say that when visiting serious technical audiophile site or talking to such EAC always comes up as the best for ripping badly damaged CDs. That and the fact that it has done a good job on every CD, no matter how bad, I fed to it. You don't think that's right? Go see for yoruself. Google it and read. – HandyGandy Sep 30 '10 at 2:57
