For tagging and other track management, i use Media Monkey. Not the best software in the world, but it’s the only tool I know that saves the ‘Album Artist’ data in a wav-file. Even if I would ditch Media Monkey’s database, I would be able to build a new database by reading metadata from the wav-files.
Apparently, it writes the Album Artist information in the [iaar] property.
See About Media File Properties - MediaMonkey Wiki
Does Audirvāna use the [iaar] property to read the ‘Album Artist’ value?
