Does anyone know of a program that will compare the CD in my drive to my already ripped files and tell me how accurately ripped they are? Sort of like EAC does, except I dont want to have to rip all my music again, I want to see how could my current rips are and if they need to be re-ripped.

Any help is appriciated,
Phil

EAC has an option "Test selected tracks" - after testing it reports their CRCs. If their CRCs match with the CRCs of your already ripped files then they're fine. The CRC of already ripped WAV you can see by opening it in EAC's wave editor. Probably there are other, automated methods of getting CRCs from your already ripped files, but I don't know them, perhaps somebody else will tell you...

Hmm ok. But my preripped tracks were ripped using iTunes. So how would I get the CRCs of those files?

To what format did you rip?

I ripped in ACC, which I believe is also mp4, but I may be mistaken.

AAC is often put in the MP4 container.

Since you ripped to a lossy format, the CRC's will not match even if the extraction was performed flawlessly.

Hmm ok, I do not fully understand what a container is, but I will read up on that. So if ACC is lossy then what format should I use?

You have a lot of options. You would do well to read the Lossless Comparison Table. Hopefully it will answer your question about which lossless format to use.

And again, it's AAC as in "Advanced Audio Coding".
