Whether or not the portal is active/enabled. For example, this parameter may be used to simulate open/closed doors. Portal diffraction is simulated when at least one portal exists and is active between an emitter and the listener. To simulate a door that opens or closes gradually, use AK::SpatialAudio::SetPortalObstructionAndOcclusion to apply occlusion to a portal, according to the door's opening amount.
