It happened few times that I had corrupted FLACs, probably 3-4 files in my entire library. One day I converted them to WAV then reconverted back to FLAC, the audio CRC ended up to be the same but the FLAC was no longer corrupted. Is this a real way to fix the corrupted FLAC? Why wasn't the WAV corrupted like the FLAC originally was?

I managed to reproduce your error. I have a file which for reasons unknown to me has had corruption for a few years, maybe ever since ripping.


MD5: 3D344C869031CB7EF4D771F44448EE94
CRC32: D78996C2
Warning: Reported length is inaccurate : 4:48.120000 vs 4:47.597551 decoded
Error: Corrupted FLAC stream
Error: MD5 mismatch

Converted to .wav and back to .flac:

MD5: 3D344C869031CB7EF4D771F44448EE94
CRC32: D78996C2
No problems found.

As you can see, foo_verifier displays what the checksums were calculated to during decoding (which is of course identical to what the new copy has), not what they should have been.
