You have to differentiate between the ID3 tags and the MP3 info tag.
Lame, for example, describes the MP3 info tag as far as I know and stores Econder information there (Lame header). But this is not a tag that you can edit with MP3Tag.
Some info tools display this data stored in the file, e.g. B. "Media Info."

Mp3Tag shows some of this information if you right-click on a file in MP3Tag and select Properties.
In addition, there are ID3V2 tag fields that can also contain such information. They can be edited with MP3Tag, e.g. the ENCODERSETTINGS tag field.
