How do I get spatialization data into my custom Wwise plugin?

Question

Hi,

I have experience writing VST plugins for DAWs, and I am learning to write plugins for Wwise.
I have written a VST spatializer plugin, that renders mono and ambisonic audio (B-format) audio to a binaural, with a scene rotator that can be controller via head tracker.
I would like to adapt the code into a Wwise plugin that I would like to run on the Oculus Quest2.

I have noticed in the IAkPlugin header that there are virtual interfaces for performing spatial audio-related processes like `virtual AKRESULT ComputeSpeakerVolumesDirect()` and `virtual AKRESULT Compute3DPositioning()`, so there are clearly interfaces in place for making plugins that perform spatial rendering operations etc.

What I would like to know is what interfaces I am need to implement and what settings macros I need to set in order to start performing ambisonic rendering.
Can anyone please tell me what I need, or point me to the appropriate documentation?

Thanks,
Simon

Hi Simon,

You can look at the documentation for Object Processors, which are a superset of effects that are aware of audio objects, to implement your binauralizer as an Out-of-Place Object Processor that aggregates all its incoming streams into a stereo output object stream.

Software Binauralizer example in the documentation: https://www.audiokinetic.com/library/edge/?source=SDK&id=soundengine_plugins_objectprocessor.html#soundengine_plugins_objectprocessor_outofplace_binauralizer.

That looks like exactly the documentation I need at this stage, thank you so much!
