Something vaguely similar to #82

Describe the solution you'd like
Pass audio to Dynamic surroundings engine to get simple reverberations in caves without all the computational overhead.
I don't know if Dynamic Surroundings has that kind of api, but would be a major step in immersion.

It would not happen that voice could turn the corner, and depending on the implementation block obfuscation per voice/player location would be impossible... (be it, all voices merged into one channel and sent to recipients).

Describe alternatives you've considered
None.

This mod does not use Minecraft's sound engine.
