but  Hmm.
I 'm trying to understand what it means when you do the spectral subtraction and you get a negative. It means that at that particular frequency range you subtracted more energy than there was actually
That means that  Mm - hmm. Yeah. So  so yeah , you have an  an estimation of the noise spectrum , but sometimes , of course , it 's  as the noise is not perfectly stationary , sometimes this estimation can be , uh , too small , so you don't subtract enough. But sometimes it can be too large also. If  if the noise , uh , energy in this particular frequency band drops for some reason.
Mm - hmm. Mm - hmm.
