Right ? I mean maybe there 's something about the variance that 's  that 's not enough or maybe there 's something else that  that one could use , but I think that , for me , the thing that  that struck me was that uh you wanna get something back here , so here 's  here 's an idea. uh What about it you skip all the  all the really clever things , and just fed the log magnitude spectrum into this ?
Ah  I 'm sorry.
This is f You have the log magnitude spectrum , and you were looking at that and the difference between the filter bank and  and c c computing the variance.
Yeah. Mm - hmm.
