Sword-fighting!  

Recommended models: Modal, Banded Waveguide

I think there's a papers on this by 
Kees Van Den Doel and Dinesh Pai (i think).

There's also an awesome paper on synthesizing
the "whoosh" sounds of things swung through air,
from SIGGRAPH a few years ago (maybe 2005 or so??)

Forge ahead!!
