Comparing CD ripper outputs ?

[Gidorra]

For the past "30 years" or thereabouts, I ripped with CDeX. It was only recently that I started ripping with EAC - and now I am wondering whether I have to re-rip my entire collection for peace of mind Have you guys ever checkummed the rips and compared? Is there an easy way to compare the rips of e.g. 20 CDs to get an idea whether my entire past efforts were rubbish, or what shall I do? I am guessing ca 700-1000 CDs total here, so I would not do that light-heartedly...

I ripped 1300 CdS with EAC. My only regret is I did not spend more time up front cleaning up the metadata. I used freedb, which is user supported, and not consistent.

I think the most efficient way is to use a fast rip, and only use the slower methods if a rip fails CRC. I believe dbpoweramp has the same features, but easier to use.

I insta paid 7 bucks for that GD3 database for EAC because the reason I switched to begin with is because CDeX seemingly would not connect to the free databases anymore, and punching in the details for some 300 CDs was not an option... I would recommend paying that for lifetime access. I am just ripping the 330 CD Karajan Box and so far all the CDs were in the GD3 database after I am ca 70% done here.

If it sounds OK it's OK. There could be some inaudible errors but I wouldn't worry about it. If you have clicks, pops, or skips you can re-rip (and hope they come-out OK the 2nd time). I've had a few occasions where EAC reported errors but it sounds OK. It didn't take long to forget which CDs had errors.

If you have WAV (or FLAC) files you MIGHT be able to check them with CueTools and AccurateRip.

EAC supports AccurateRip but I've only used it while ripping and I'm not sure if it works on previously ripped files.

Is there an easy way to compare the rips of e.g. 20 CDs

foobar2000 bas a bit compare feature and I[m pretty sure it only checks the audio data and ignores metadata.

FLAC by default writes a checksum to the files it creates. You can verify checksums using foobar2000:

To verify FLAC checksums in foobar2000, use the built-in "File Integrity Verifier". Highlight your FLAC files, right-click, select Utilities, and then Verify integrity to check for audio corruption, which compares the embedded MD5 checksum against the decoded audio.

If there was anything really wrong, you'd probably hear it. It would not be something like a subtle EQ change

 

[kemmler3D]

Agree that if you can't hear any problems, you shouldn't borrow trouble. Passing CRC with every bit in its place is something people who are aiming for something like archival use care about. Ironically from what I've seen, mostly pirates who intend for their illegal copy to be a truly perfect one.

OK.. Friday night, innit... lonely hearts I just ripped a CD with CDEX and EAC, compared the md5s with MD5Checker for Windows, and only 1 track came up with the same checksum

MD5Checker

Probably not a good idea. It is the MD5 of the entire file not the audio part. Rippers might reserve some space in the header to avoid rewriting the whole file if you changes a tag. If one uses PADDING=100 and the other PADDING=101 you sure get a different MD5.

Better do what DVDdoug suggested. Use the Foobar binary comparator, it compares the audio part only, not the tags.

I second the recommendation of cuetools. You can have it check the entire collection against the cuetools database and also the AccurateRip database, and in some cases it can even repair rips.
