Remarks
Retrieves the actual EAX effect's reverb parameters for the given output device.
EAX effects can be applied/retrieved only if the IsEAXAvailable method returns TRUE. You can change the current EAX settings through a call to the SetEAXEffectParams method.
See the How to apply special effects to a playing sound section for further details.

fReverbVolume
|
Reference that, on return from the method call, will contain a floating point value representing the volume of the reverb's effect.
The value is expressed in percentage and can assume values from 0 to 100.
|
fReverbDecayTime
|
Reference that, on return from the method call, will contain a floating point value representing the time, expressed in seconds, for reverb to fade to -60 dB.
Supported values can range from 0.1 to 20
|
fReverbDecayHFRatio
|
Reference that, on return from the method call, will contain a floating point value representing the reverb's decay HF Ratio.
The value is expressed in percentage and can assume values from -100 to 100 with the following meaning:
-100 = high frequencies decay quickest
0 = low and high frequencies decay equally
100 = low frequencies decays quickest
