Audio Extending Unity's Audio System

What audio tools would everyone want to see added to to unity? Personally, I think the spatialization system from something like steam audio would be a great addition to the native unity tools. An impact sound synthesis tool that could handle different materials/geometries would also be great. Lemme know what you guys think!

 

They already integrated Google Resonance audio system which is similar to Steam Audio ... Steam Audio is also available as a Unity plugin package anyway so it's simple to set up and use those!
