how to copy all metadata/tags from source to destination?

2024-07-14 11:55:56

as a test, I ran the command below

wavpack --allow-huge-tags --import-id3 -h "my-dsf-file-here.dsf"

And most of the tags were copied across except for custom ones (example: COMPOSERSORT, various MusicBrainz tags and etc)

How can I make sure all metadata are copied across? I looked at the available options (from https://www.wavpack.com/wavpack_doc.html) and didn't find anything else required.

Thanks!

The issue here is that there isn't, as far as I know, a universal tag mapping between ID3v2 and APEv2 tag fields. In my code I put in all the ones I found at one point, and you can look at the list  here in my code.

Obviously I'm missing TSOC (ComposerSort) and I could easily add that, but that doesn't mean that it's a recognized APEv2 tag or that any software will actually use it, but at least it will be in there. I'm happy to put in any others you find/need, but obviously the same caveats apply.

You could also use a program like Mp3tag which, being a dedicated tagging program, has better support for the more obscure tags. It's free and can easily copy tags from DSF to WavPack files.

A lot of MusicBrainz tags will be TXXX of which there can be multiple. What fun...



Oh. and they are named differently in id3/m4a vs vorbis/ape.

Note the spaces vs _ differences. It makes no sense at all. 

edit: I just realised I posted a very contradictory and maybe confusing screenshot. I'm using a tagger that completely ignores their standards. While that is an mp3 file, I'm following the naming standard for vorbis comments.

I added the TSOC (ComposerSort) to the list of tags I import. Like I said, I'm happy to add anything else that's missing to the list.

As for the TXXX tags, I do import them but I just use the supplied custom field name verbatim. I did not know about those crazy translations with the spaces and underscores. What a nightmare; this is why maintaining a tag utility is a full time job!

fb2k has never done any of that mapping either so I really wouldn't bother. Obviously lossless to lossy via conversion is the most common route but copying tags is also supported...

Your suggestion of using mp3tag might do the job but I'm too lazy to test it.
