Yes, interesting feedback. Theres three models I've got atm. The Wright
Mendorp and N-Wave model are expensive so I can only render with a certain
density. To get close ups with a proper BANG! you need a lot of density.
Where I fill in with noise based models (cheating) it loses the detail.

But the aftershocks and late reflections are sounding okay I think. 
I'm trying two ways, one with a giant multi-tap and filters, which is
like a monster FIR filter, and another using convolution in Csound.
Not sure which is best yet. Definitely not real-time models, but they
could possibly be simplified for real-time execution.

Nice one!! Good find Marius. Obviously pdfs are good because I can
copy and paste refs and search, but thanks for finding me A.A Few.
Will read this one tonight.
