#94 "ERROR: during analysis (decoding file)"

[Anonymous]

I have a lot of FLAC files that I created using the official encoder. They all play perfectly and "metaflac --list" works fine too.

However, for a majority of the files, "metaflac --add-replay-gain" terminates with "ERROR: during analysis (decoding file)".

I'm running version 1.2.1 of the flac tools.

can you host a problem file somewhere, along with the exact metaflac command you used?

Here's a file:

The command that fails is "metaflac --add-replay-gain [filename]".

the FLAC file is corrupted, so replaygain cannot be calculated:

$ flac -t 01\ Azita\ -\ Better\ end\ in\ time.flac

How can I proceed to figure out why such a large percentage of my FLAC library is similarly corrupted, then? I rip from CD using cdparanoia and flac.

dunno, I've been getting a lot of reports about errors transferring files (not just FLAC) to some bad external HD (usually USB)

These files are all on the same drive they were created on, and the drive tests out healthy.

Is it possible that there could be a way to fix the corrupted files? Since the audio plays fine, with maybe just a faint click at the point of corruption. Or could "metaflac --add-replay-gain" be told to skip over the little error in the same way that the audio players do? I have no desire to re-rip the bad files, since there are thousands of them and they all sound fine.

decoding with the -F option to flac will allow it to skip over errors and decode as much as possible. how audio players handle it depends, some stop on any error, some act skip over errors, some have an option.
