Not sure about being "official" but Auralization is at least a term
used in academic discussion and acoustics consultation for some years
(maybe 15-20 years at least now?), meaning the scientific simulation
of sound sources in real space with real acoustics.
where you can find some publications, also some software and other
... that said, in audio engineering, it'd be a down-mix that you're
after - and that can be done however you feel like it!
