Remarks
Sets parameters related to the Interactive 3D Level 2 Reverb effect. The current parameters for the chosen effect can be retrieved using the Effects.DirectXEffectParamsGetL2Reverb method.
DirectX effects requires the availability of DirectX version 8 or higher on the target system and can be applied only if the IsDirectX8Available method returns TRUE.
See the How to apply special effects to a playing sound section for further details.
