It 's very similar.
Yeah. But again , you 're  you 're more or less doing what they were doing , right ?
It 's  it 's different in a sense like I 'm actually cleaning up the cleaned up spectrum which they 're not doing. They 're d what they 're doing is , they have two stage  stages of estimating the Wiener filter , but  the final filter , what they do is they  they take it to their time domain by doing an inverse Fourier transform.
