Wwise SDK 2018.1.11

The maximum number of paths to the listener that the sound can take around obstacles. Applies only to geometric diffraction, and not sound propagation. Diffraction paths map directly to virtual sound positions. Setting diffractionMaxPaths limits the number sound positions that are rendered for the game object. Setting diffractionMaxPaths to 0 effectively disables geometric diffraction for this sound emitter.
