I don't actually know exactly how to set these, but I have tried a few combinations to try and make it work.
I thought that setting Read: to ID3v2.3 and APE and Write: to ID3v2.3 and APEv2 would work.
When I do this, it allows me to see and edit the APE tag.
But then I run this Action: Remove fields: "REPLAYGAIN_ALBUM_GAIN; REPLAYGAIN_ALBUM_PEAK; REPLAYGAIN_TRACK_GAIN; REPLAYGAIN_TRACK_PEAK", it does what I want to the APE tag, but wipes all of my ID3 tags clean.
I want to preserve all the info in the ID3 tags and remove those four fields in the first post
I have thought about it a bit, and I basically want to save those 3 MP3Gain fields found in the APE tag, into the ID3v2.3 tag and delete the APE tag altogether.
How would I achieve this (without wiping my ID3v2.3 tags)?
And also, how would I reverse this in the future (without wiping my ID3v2.3 tags?
I did try this, but it doesn't merge the APE tag info with the ID3v2.3 tag info, it simply copies and pastes over top of the ID3v2.3 tag, leaving all the fields blank again...
AFAIK are the ***gain fields only available in the APE tags but not as MP3 fields.
So, the idea to convert the APE-only fields to MP3 fields will not work.
But you can write TXXX frames in ID3v2 tags. You can, for instance, manually write a TXXX/MP3GAIN_ALBUM_MINMAX field in an ID3v2 tag. So is there some way to copy an APE field to a TXXX frame of the same name? I'm guessing that the genuinely oddball implementation of the read/write settings for different types of tags in Mp3 files precludes doing this.
