OK , so the Wiener filter , it 's  it 's like  it 's like you try to minimize  I mean , so the basic principle of Wiener filter is like you try to minimize the , uh , d uh , difference between the noisy signal and the clean signal if you have two channels. Like let 's say you have a clean t signal and you have an additional channel where you know what is the noisy signal.

And then you try to minimize the error between these two.
Mm - hmm.
