Can I ask just a  a high level question ? Can you just say like one or two sentences about Wiener filtering and why  why are people doing that ?
Hmm.
What 's  what 's the deal with that ?
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.
