[everybody's x]

basically a computer models what happens when a signal passes through a particular environment or piece of gear, or signal chain using a brief pulse of white noise.

the difference between the unaffected white noise and the modeled version are subtracted. the result is an "impulse"
theoretically you can then apply this impulse to any signal you want resulting in the signal being affected as if it passed through that particular environment.

this is what "modeling" means or "convolution"
