Bit field that allows for filtering of reflector surfaces (triangles) for this sound emitter. Setting/or clearing bits that correspond to the same bits set in the reflectorChannelMask of each AkTriangle can be used to filter out specific geometry for specific emitters. An example usage is to disable reflections off the floor for sounds positioned at the camera. When processing the reflections, this bit mask is ANDed with each potential triangle's reflectorChannelMask to determine if the reflector/emitter pair can produce a valid hit.
