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. - Steve
