How to use random 3D position while using diffraction and transmission for Ak Rooms and Portals?

Question

Hello guys,

I'm building a ambience system for an RPG with Wwise and Unity. I use the AkRoom and AkRoomPortal scripts to create obstruction and occlusion in houses.

 

To create a dynamic ambience I would usually create a stereo layer with basic ambient sound and add randomised oneshots to create variation. For the oneshot I usually use (in Wwise) positioning/3D Position/Emitter with Automation. If you choose this option Wwise cant use the Diffraction and Transmission anymore.

 

I am looking for a way to use randomised 3D positioning in combination with AkRooms and Portals. (or something similar)

 

I'd like to discuss your ideas and workarounds.

Answer 1

It seems to be Wwise is having limitation for Diffraction and Automation.
My work around is making the sample source have some different panning L/R or making 2 Mono into one Stereo, and then make use of "SPREAD" inside Attenuation.
For 3D Spatialization, you can choose Position or Position + Orientation base on your preference, which ever outcome you would prefer. But I'll recommend using Position + Orientation.

Below is the example Wwise had at their Youtube channel
