Many of the same considerations discussed in Cinematic VR apply to Auxiliary Busses used for environmental Effects. The RoomVerb and AK Convolution Reverb Effects support ambisonics natively, however Matrix Reverb does not. You can use them on a stereo, 4.0, or greater bus, whether you want to use the front-back delays or not, and route them to ambisonic busses. Their output will be encoded to ambisonics following the same rules that apply to 2D sounds. While you can do the same with RoomVerb, you can also use it directly on ambisonic busses. The directional channels will consist of decorrelated signals, similar to standard multichannel configurations. The higher orders result in more decorrelated channels and will, therefore, require more processing. We encourage you to experiment to find the desired balance between quality and performance.
