it sounds like a man with a sore throat is singing the song instead of a lady, there are skips or there is significant noise
If the source is a CD in good condition, that shouldn’t happen.
If you have those problems, it’s more likely due to playing issues. I mean, the data in the CDR is correct, but the player is not able to read well enough… this can happen if your player is “picky” or if the media is not very good quality or has poor compatibility, or a bit of everything…
To know if the errors are in the data, you can see if those errors are present exactly with every reader you have… (CDROM, CDRW, audio players)
would doing a binary file compare on the wave files ripped from both the original/backup
Use “Compare WAVs” tool in EAC.
The backup should be equal to the original (except offsets). Anyway, even with “equal” data in both CDs, the reader can play the CDs differently if it isn’t able to read a CD properly. Audio players interpolate (“guess”) missing data instead of muting if there are small errors.
Don’t use CloneCD for anything about audio.
a given fact that the copies will almost never be perfect 1-to-1 copies
Audio copies with modern drives are perfect (except for offsets) if the ripping process was successful. And the ripping process is usually perfect if the CD is good.
You can use Secure Mode in EAC to be sure. EAC extracts every sector twice and compares them. If they’re equal, it’s supposed that block is OK.
You can also do a “Test Device” in Feurio, but most modern drives have no problem with that test. (Program Parameters -> Test Device). It repeats a ripping 10 times, and also tries to provoke jitter errors.
If your drive returns C2 pointers (that test also show it), you can be sure that extraction was perfect if the C2-error detection layer didn’t have to correct any error.
EAC can use C2 pointers to speed up extraction and Feurio can report C2 errors.
