Parameters

TInt & aRMin The source-to-listener distance below which the sound level is constant
TInt & aRMax The source-to-listener distance above which the sound level is constant or zero
TBool & aMuteAfterMax Indicate if the sound is muted beyond RMax
TUint & aRollOffFactor Multiplier factor to source-to-listener distance
TUint & aRoomRollOffFactor Multiplier factor to source-to-listener distance for Room effect.

RollOffFactorMax(TUint &)
