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.
Oh. So maybe we can just substitute one of these wave forms and um  then do some kind of zoom in on the spectrogram on an interesting area.
Something like that. Yeah.
Uh - huh.
