title: Deconvolution of a signal by using Wiener filter
body: <p>Could anybody explian how to use Wiener filter to revocer the audio signal from low-pass filter in Matlab?
  I filtered the signal, after that I used simple deconvolution by dividing filtered signal with frequency response of the LPF, but it didnt give me any result. I didnt get restoration at all. I have checked the LPF, it works correct. I need some information about using Wiener filter for audio files, but there are only answers about deblurring images. Thank you in Advance!</p>
