Hi. Can someone please help me understand the syntax for non-standard MP3 tags.
By experiment I found that I can add my own tag to a file (eg XBOB). I can see it in the extended tags pane as XBOB and its value. I can also display it as a custom column in the filelist by entering %XBOB%.
However, for standard tags the syntax is different. In the extended tags pane I see ARTIST and not TPE1 which is the actual name of the frame. And I have to put %ARTIST% for the name of the column. If I put %TPE1% as the custom column it does not work. So MP3tag uses its own internal names to represent the actual frame names.
So far, so good. It is more convenient to use an internal name like ARTIST rather than something like TPE1.
But here is where I'm getting confused. A program like Media Monkey inserts custom tags that are similar, but not identical, to standard tags. Something like "COMM:Songs-DB_Custom1". I'm not sure exactly what MM is writing. MP3tag displays it as "COMMENT SONGS-DB_CUSTOM1" but this is not the actual name of the frame. Where can I see the exact frame name as stored in the file?
I'm having a similar problem with Replay Gain. Something gets inserted in the file and MP3tag displays it as REPLAYGAIN_TRACK_GAIN. But what is actually written? Is it a RVA2 tag or an RGAD tag or a TXXX?
You may think it's not necessary to dig down to this level of detail. But I feel that this is the only way to understand properly what's happening in complex situations. So can anyone please show me how to access the actual frame names directly?
