Cool. Do you wanna go , Stephane ?
Uh , yeah. So ,  I 've been , uh , working still on the spectral subtraction. Um , So to r to remind you   a little bit of  of what I did before , is just  to apply some spectral subtraction with an overestimation factor also to get , um , an estimate of the noise , uh , spectrum , and subtract this estimation of the noise spectrum from the , uh , signal spectrum ,  but subtracting more when the SNR is  is , uh , low , which is a technique that it 's often used.
" Subtracting more " , meaning  ?
So you overestimate the noise spectrum. You multiply the noise spectrum by a factor , uh , which depends on the SNR.
