An impulse response is just a /very/ large FIR filter, one way they can be
created is by a physical analysis, but thay can also be generated
synthetically. With an IR impulse its possible to capture and recreate any
linear (ie. non- non-linear) process, within reason.
I see what your saying about reverb and so on v's having a good room in
the first place, but not all audio has an acoustic source.
