Wwise SDK 2021.1.14

Use the Wwise occlusion curve for modeling the effect of transmission loss on a sound. The transmission loss factor is applied using the occlusion curve defined in the wwise project settings. Transmission loss is only applied to sounds that have the Enable Diffraction and Transmission box checked in the Positioning tab of the Wwise Property Editor. Transmission loss can also be applied using the transmission loss built-in parameter, mapped to an RTPC (the built-in parameter is populated whether AkSpatialAudioInitSettings::bUseOcclusion is true or false). While the occlusion curve is a global setting for all sounds, using it to simulate transmission loss is preferred over an RTPC, because it provides greater accuracy when modeling both transmission and diffraction. This is due to the fact that RTPCs cannot be applied to individual sound paths, therefore any parameter mapped to a transmission loss RTPC will also affect any potential diffraction paths originating from an emitter.
