Sorry to beat a dead horse.
I'm not rationalizing the eq'ing of reflections, rather looking at the frequency of the particular reflection to ensure that the treatment is sufficient to handle the content. I realize as well, that these areas of reflection are not necessarily a spot, but a series of spots...a zone if you will.
Given the etc plot shows spikes at points in time... and this particular point in time points us to the directions of where these are coming; could we not superimpose that same point in time on the waterfall, and deduce the frequency content of the reflection(s)? For example, it would tell us how thick the absorption needs to be at this particular reflection, or if a combination of absorption...again how thick, and what depth our diffusor on top of the absorption should be to achieve successfully diffusing the reflection.
If this isn't a clarification of my intent I apologize, but perhaps I need a dumbed down explanation of why I may be wrong.
