OK, I had it written in the OP but took it out.
The impulse is a sweep, balloon pop, starter pistol used to excite the room, hardware device, speaker.
It gets recorded with a microphone which gets you the sound of the impulse + the mic + the room. A hardware reverb would be recorded direct.
That recording is then "deconvolved" where the original sound is removed from the recording, leaving just the reverb (+ mic) or just the speaker.
The deconvolved file is the impulse response. This sound has an envelope that reacts to transients (giving you sustain or echo) and a frequency curve that is applied to everything going through it.
