[MAC] iTunes Replay Gain (iTunNORM tags) support

Please extend the replay gain support now in xbmc to read the iTunNORM tag from alac and aac files.

please stop using bastardized, nonstandard tags.

xbmchead, not only those tags are non standard, as spiff points out, but replaygain support in iTunes is partial at best. The iTunNORM tag is equivalent to the song replaygain value and does nothing for albums.

What logic of implementation could one adopt to have it work in a worthwile manner? If you play only random playlists... fine. Otherwise, you could have a 9db jump in volume when switching from random playlists to albums.

Unless you consider a valid approach playing back albums applying songs replaygain values, which leads to ridiculous results when playing back gapless albums.

I'm talking about alac files mind you, not mp3 files.

What is the standard tag for volume normalization in alac files?

As far as I know there is ONLY iTunNORM as replaygain is not supported in alac files. One can use the replaygain ALGORITHM to write to to the iTunNORM tag as iVolume does, thus providing replay gain support as well as the ability to replaygain by album or track, but only in iTunes, not xbmc, because it won't read iTunNORM.

Yes, I do use randomize all the time.

How should I volume normalize my alac music collection?
