Yeah. Mm - hmm.
And uh uh , given  you know , given that , uh  you could uh uh come up with some kind of estimate of how much of the low frequency energy was  was explained by   by uh uh those harmonics.
Mm - hmm.
Uh. It 's uh a variant on what you 're s what you 're doing. The  I mean , the  the  the mel does give a smooth thing. But as you say it 's not that smooth here. And  and so if you   if you just you know subtracted off uh your guess of the harmonics then something like this would end up with  quite a bit lower energy in the first fifteen hundred hertz or so and  and our first kilohertz , even.
