Uh , but  but , you know , that 'll  uh , it 's clear that we , uh  we are not  with the real case that we 're looking at , we can't just look at reverberation in isolation because the interaction between that and noise is  is considerable. And that 's I mean , in the past we 've looked at , uh , and this is hard enough , the interaction between channel effects and  and , uh  and additive noise , uh , so convolutional effects and  and additive effects. And that 's hard enough. I mean , I don't think we really  I mean , we 're trying to deal with that. In a sense that 's what we 're trying to deal with in this Aurora task. And we have , uh , the , uh , uh , LDA stuff that in principle is doing something about convolutional effects. And we have the noise suppression that 's doing something about noise. Uh , even that 's hard enough. And  and the on - line normalization as well , in that s category. i i There 's all these interactions between these two and that 's part of why these guys had to work so hard on  on juggling everything around. But now when you throw in the reverberation , it 's even worse , because not only do you have these effects , but you also have some long time effects. And , um , so Dave has something which , uh , is doing some nice things under some conditions with  with long time effects but when it 's  when there 's noise there too , it 's  it 's  it 's pretty hard. So we have to start  Since any  almost any real situation is gonna have  uh , where you have the microphone distant , is going to have both things , we  we actually have to think about both at the same time.
Hmm.
So , um  So there 's this noise suppression thing , which is sort of worked out and then , uh , maybe you should just continue telling what  what else is in the  the form we have.
Yeah , well ,  the , um , the other parts of the system are the  the blocks that were already present before and that we did not modify a lot.
