I'm in the process of backing up 500 CD-DA discs in FLAC format (using EAC). I ran a shell script to test (flac.exe -t; flac version 1.1.1) the 4000 FLAC files on my hard drive so far and found that flac.exe reported errors for 36 files. All errors are the same:

<filename>: *** Got error code 0:FLAC__STREAM_DECODER_ERROR_STATUS_LOST_SYNC

The files decompress fine, but now I'm not sure if I got the exact WAVs back. What does this error message mean, and how severe is the error? Moreover, is there a way to avoid it when compressing WAVs to FLAC in EAC?

OK, found the problem. it is a decoder bug that is exposed when there is an id3 tag at the end of the file AND the last frame of the audio stream has a certain blocksize. integrity of the audio is not affected but the sync error is annoying. no need to re-encode either.

it's fixed in CVS and will be in the next release.

interesting. yea it has happened to me a bunch, and i just decoded and reencoded (which stripped the id3 tag, i guess). i did it because foobar always pops up a message and i wanted it to go away smile.gif

so a fix would be to set EAC to not "add ID3 tag", huh? in fact, the ID3 tag really does nothing and has no place/purpose in a flac file, cuz it uses a different tagging system?
