For the first release of FAudio we focused on what FNA and XACT needed, but now that this is looking to go into a whole lot more games we should look at the rest of the X3DAudio features.

The stubs are here:

https://github.com/FNA-XNA/FAudio/blob/master/src/F3DAudio.c#L1538

Don't expect a whole lot of information out there - the MSDN docs are completely useless and many months of looking for existing research on this turned up completely and entirely empty. If you're working on this, it's because you REALLY know what you're doing (I certainly don't).
