Tag editing problem

[BlueDog]

Sorry, I deleted yesterday's post as I was barking up the wrong tree - no pun intended.

I had the same issue yesterday with a download from 7Digital and, on further investigation, the problem appears to stem from a combination of things.

Firstly, the Vorbis comment block in the downloaded files does not strictly adhere to the spec as there is no vendor string set.

Secondly, updates in dBpoweramp R16.2 cause a new (correct) comment to be created in addition to the existing block if the vendor string is not set.

I'm erring on the side of blaming the download vendor for this one, as the problem wouldn't occur if the vendor string was set correctly in the first place.

The easy fix is to use dBpoweramp converter to 're-encode' the files, this rewrites the existing incorrect tags with the correct structure and allows you to edit to your heart's content afterwards with no problems. Just select all files, right-click and select convert - I keep everything in FLAC level 5 anyway, so I just select that option and let it do its thing.

You can see the difference in the attached screenshots between the 'before and after' files opened in a hex editor. The vendor string in the corrected file is 'reference libFLAC 1.3.1 20141125'.

Yeah, I know, I need to get out more ...
