I don't want to be arrogant, but the acoustic simulation itself is really 
an implementation of issues that have been published about 10 years ago. 
In the DIVA demo (by us) in Siggraph'97 (Electronic Garden) we 
demonstrated real-time acoustic simulation with interactive listener. The 
novel things in UVAS and UVSRP are that materials and geometry could be 
changed interactively and sound sources can move in real time. However, we 
already implemented (and published) these issues in 1998, but at that time 
they didn't work in real time. The only really new thing academically in 
the Universe Audio part is the geometry reduction.

Yes. Light refracts and sound diffracts.
