Spatial Audio - Diffraction for one source sound in a room with multiple portals

Question

I set a source sound in a cube room with 6 portals in Unity(the front and left side with one portal, the back and right side with two portals). When the listener is in the outside of the room and in the middle of different direction of portals( one X direction, one Y direction), there is clipping sometimes. Is there a way to figure it out?

Answer 1

Hey Jalo,

Sounds strange.

What version of the Wwise Unity Integration do you use? Also, do you mean clipping like signal overdrive or that it cuts off?
Actually, any way you can record this and put a link for the video here?

Otherwise, I would use the Voice Inspector to see what happens to the specific sounds signal flow.

Hey Mads! I used the Unity 2018.4.0f1 version and the Wwise 2019.2.5 version. And actually I wanna design a room with a live music background ambience. When the listener is in the room, the spread will be 100%. When the listener is outside the room, the sound will be diffracted and transmitted by the portals. What I did is I set the live music event in the room component or set it in the room tone of ak room. And you can check the portal and room design from the below link.If the volume is too low, you can increase the monitor value a little bit.

As you can see, there are 6 portals with 1 room. And the front portal with a wood entrance which has a ak surface reflector with it. When the listener stand in font of the wood entrane. The sound will be cilpping, and if I set the surface reflector uncheck in unity, it will be okay.The below is the video to show the problem.

What's more, when the listener is near the portal(window), the sound will be gone suddenly, if I totate the camera, it will be back. The problem is showed below the link.

If I uncheck the ak surface reflector on the room, the sound will be played in a right way. Can it be said the ak room can not be set with the ak surface reflector at the same game object?? But I see you set the reflector with room in the Wwise up on air. Or I did it in a wrong way. The link below is the video to show the problem.
