This is really weird: all kinds of different errors, but indeed all in the last few percent. The small part you send looks fine: there's probably a corruption somewhere, but it's not obvious. The strange thing is that the frame it happened is actually the frame of the fade-out: all previous frames contain audio, the frames that follow it are all zero. There is no (feasible) way to fix this, unfortunately. If tried to find the cause of the problem, but I can't be conclusive. First: in the changelog for FLAC 1.1.3 there is this entry: > Fixed a bug where sync error at end-of-stream of truncated files was > not being caught It might be that your ripper produced not properly terminated files which 'silently chrashed' FLAC. It might be k3b (if you indeed used that program as for ripping) as it has had some issues with FLAC encoding and decoding in the past (I've had some of those problems myself) see here: https://bugs.kde.org/buglist.cgi?bug_status=__all__&product=k3b&content=flac I think this is the only possible explanation: this can't be failing storage media or file transfer methods, it's just too regular, so this problem has to have occurred at encoding them. > I wrote a little script checking my whole collection for corrupt files using > > flac -wst "$1" 2>/dev/null || printf '%3d %s\n' "$?"

Anyway, I'll send this case to the developers, they might find a cause, but I think your files can't be fixed, you'll have to re-rip them or re-encode them without the last tenths of a second of the file. _______________________________________________ Flac mailing list [email protected] http://lists.xiph.org/mailman/listinfo/flac
