(open source) SpatDIF project: http://redmine.spatdif.org/

Interestingly enough, also see these links on 3D Audio Alliance (3DAA), which 
describes itself as: 

> The 3D Audio Alliance (3DAA) is a new, member-funded industry alliance 
> dedicated to advancing the state of the art of 3D audio throughout the entire 
> electronic entertainment ecosystem.
