First post so be gentle ... Been using mp3tag for a while and not given too much thought to tag types. As long as my mp3 player of choice picks everything up that's not been a problem and I've left the tag types in the Options > mpeg section to defaults (I'll just add that I'm only interested in mp3 files here). The issue of tag types came up recently in relation to car head units and the fact that they sometimes don't support all that they should. Mine only gives track number and elapsed time though just after a factory reset it did give artist/track etc briefly. Anyhow ...... the issue is not the HU but I was after creating some tracks with specific tag types to test this out. Turns out that a lot of my mp3 files come from various sources that aren't too fussy about tag types. And, to be honest, all I do is add missing ones and edit existing ones to my satisfaction.
So, to get to the point after all thatr preamble, I'm looking for a way to read in all existings tags of all types from an mp3 file but rewrite them ALL as one specific type. For example, read in all APE, ID3v1 and ID3v2 tags but write the lot as ID3v2. I've found some hints in other sites and this one but no reproducible way to do this.
Which brings me to a secondary issue and that's not knowing exactly how the Options > mpeg > R/W/D work. I assume that the 'Read' happens at file read time? When you point mp3tag at a folder? And it only reads those tag types that are 'checked'? So the other(s) is/are ignored?
The 'write' happens on a CNTL-S? And only writes the tag type(s) that is/are 'checked'? But ..... does that mean that a tag of type X is only written IF that tag type X is checked? Or does it mean that all tags of type X and Y and Z are written but only as tag type X (if X is write-checked)?
And at what stage does a tag 'delete' occur? When you do a CNTL-S or when the file is initially read?
And how are these options releated to the contect menu 'tag cut/copy/paste' etc?
Right, I know I've probably asked some questions that have obvious answers to some, just not to me. I just need to get my head around exactly how these things work and then I should be fine.
All comments appreciated.
