This is one area where hardware accelerated ray-tracing has me excited. I like the idea of walking sound sources to the observer. Unlike light, you need to account for the speed of sound through mediums, which adds an extra layer of cool imo. You also don't need to update at the audio sample rate, since most objects will not be moving very fast (unless you want trans sonic simulations, which would be exotic and cool).
Forget all of the little hacks. Sound processing is cheap. In 2020 it is unnecessary to select from a set of pre-baked filters and applying them to some predefined volume (ie this room is echoey, this room is absorbant, etc.)
This is one area where software has regressed then stagnated [0]. It doesn't make any sense, other than it wasn't prioritized. I think it's only a matter of time before engines go back and finally complete the audio simulation problem.
