When is a corrupt file not a corrupt file?

This doesn’t warrant a support ticket, as it’s not actually causing an issue, but I have 1 track (FLAC) on an album i’ve just imported that has a red “corrupt” above the title. But the track plays fine? There doesn’t appear to be anything wrong with it. Does anyone know if there’s a specific way to identify what Roon sees as the issue?

Usually in my experience it is bad header information in the file. Some players ignore header errors and play the file, Roon does not. I correct it by using a program to save the flac as flac and that will re-write the header information.

I use the flac --test option, and if there is an error, re-encoding sorts most issues. AFAIK, Roon is using the checksum.

I’ve not tried this online test, but it looks like it does the same.

And worth noting that a bit flip in a single least-significant bit would make it fail the test but would of course be completely inaudible

I use a free program - AudioTester - but unfortunately it looks like the creator’s website, www.vuplayer.com, no longer exists.

yeah, this. There’s nothing noticeably wrong with the file, just the red “corrupt” glaring at me.

I’ve tried converting FLAC > FLAC using XLD, but that didn’t seem to make a difference to the file being flagged as corrupt. oh well, it’ doesn’t affect playback so i’ll just cope with it!
