It's funny to see this now because I've been for a couple weeks looking into audio spacialization. After a lot of research and even trying to write my own spatializer plugin, I found that Game Engines have probably the most complete toolset to do this task. (Specifically I'm using Godot with https://valvesoftware.github.io/steam-audio/).

Steam audio is pretty awesome in that regards because it supports HRTF and all the physical based goodies like occlusion/reflection and sound propagation. So you can get really really immersive spatial audio.

The only downside with this solution is that you can't do offline rendering. So my question is:

can Audiocube do offline rendering? seems like it would be one killer feature for my use case.
