Mmm. You Yeah. We are playing  we are also playing , trying to put other spectral subtraction mmm , in the code. Um , it would be a very simple spectral subtraction , on the um , mel energies which I already tested but without the um frame dropping actually , and I think it 's important to have frame dropping if you use spectral subtraction.
Is it  is spectral subtraction typically done on the  after the mel , uh , scaling or is it done on the FFT bins ?
Um ,
Does it matter , or  ?
