| Re: speaker location and graph help
The scaled down versions of the main energy-time plot you see on the LHS are distortion components, each is due to a single distortion component (2nd harmonic, 3rd, 4th etc). The further to the left you go, the higher the distortion order. You may find these easier to see on the main impulse response graph, the level of each peak on that graph relative to the main shows the level of that distortion component, broadly speaking. It is easiest to see the distortion responses with short sweeps, as the longer the sweep the further into negative time the distortion elements are pushed so fewer harmonics are visible.
Distortion comes from the system, in particular the speakers, not the room.
