Please implement the missing XAudio 2 functions

[GoogleCodeExporter]

The functions XAudio2CreateReverb, ReverbConvertI3DL2ToNative and so on(see 
http://msdn.microsoft.com/en-us/library/ee415905%28v=vs.85%29.aspx ) are not 
implemented yet. 
They are needed for creating the reverb effect caused by 3D sound sources in 
combination with the X3DAudio API. 
An example of the usage of this functions may be found in the 'XAudio2Sound3D' 
example of the DirectX SDK (version june 2010). 

Kind regards, 
trick
