I have just started had to update some ReplayGain values is a number of my older ripped albums/tracks using R128. I then ran an mp3tag action below that I have used for years
$rg2sc(%REPLAYGAIN_TRACK_GAIN%) which updates COMMENT ITUNNORM field.
All fine so far and the value changes (albeit all 10 blocks of 8 hex numbers are the same value, but I understand that is correct from reading elsewhere)
Then I go into iTunes and do Song Info which should reread all the tags, which it does for normal tags but it does not appear to be rereading the COMMENT ITUNNORM tag.
The volume value under the File tab in Song Info does not change.
Seems to be that iTunes only reads this tag when the track is first imported or maybe I am doing something wrong by rerunning the mp3tag action to generate a new soundcheck value.
Does anyone know how to refresh the soundcheck value in iTunes without having to delete and re-import the tracks since I'll lose playcounts/ratings etc
