I am using the command line version of mp3gain which first calculates the gain values and THEN applies them to the data. During the application stage it writes an extra tag called "mp3gain_undo" which contains the number of 1.5dB steps it has adjusted the data by. The track gain field then contains remaining adjustment needed for perfect normalisation (after the whole number of 1.5dB step adjustments). Therefore, for the mp3 file, if I do:
total gain = (mp3gain undo)*1.5 + track gain then this almost exactly equals the value in the flac tag. I haven't quite figured out what's happening with the album tags yet. I presume that the application of the gain to the data itself (as done by mp3gain) only applies to the track gain. The album gain is only stored in the tags I presume....? In any case, I figure I need to only calculate the tag values and not do anything to the data itself. Presumably this can only be done via the GUI version of mp3gain...?
