Yeah. The main thing that struck me in looking at those two spectrograms was the difference in the high frequencies. It looked like  for the one that was farther away , you know , it really  everything was attenuated
Right.
and  I mean that was the main visual thing that I noticed.
Right. But it 's  it 's uh  So. Yeah. So there are  clearly are spectral effects. Since you 're getting all this indirect energy , then a lot of it does have  have uh  reduced high frequencies. But um the other thing is the temporal courses of things really are changed , and   and uh we want to show that , in some obvious way. The reason I put the wave forms in there was because  uh they  they do look quite different. Uh. And so I thought " Oh , this is good. " but I   I just uh  After  after uh they were put in there I didn't really look at them anymore , cuz I just  they were different. So  I want something that has a  is a more interesting explanation for why they 're different. Um.
