um Well it 's this musical noise which is annoying if you d you do some kind of on - line normalization after.
Right.
So. Um. Yeah. Well. Spectral subtraction and on - line normalization don't seem to  to go together very well. I
Or if you do a spectral subtraction  do some spectral subtraction first and then do some on - line normalization then do some more spectral subtraction  I mean , maybe  maybe you can do it layers or something so it doesn't  doesn't hurt too much or something.
