Uh.
Yeah. So we 'll see what happen with this. And  Yeah. So what happened since , um ,  last week is  well , from OGI , these experiments on  putting VAD on the baseline. And these experiments also are using , uh , some kind of noise compensation , so spectral subtraction , and putting on - line normalization , um , just after this. So I think spectral subtraction , LDA filtering , and on - line normalization , so which is similar to  the pro proposal - one , but with  spectral subtraction in addition , and it seems that on - line normalization doesn't help further when you have spectral subtraction.
Is this related to the issue that you brought up a couple of meetings ago with the  the  musical tones
and  ?
