Does some have an example of what a Wiener filter (that can be used directly with
scipy.signal.wiener) can be useful for, in sound processing (it seems that such adaptive filters can be useful for noise reduction, etc.) ?
I tried with various (noisy + sinusoids) soundfiles (read into an array
x) with the command
y = wiener(x)
But it doesn't give such great result... (Normal : I cannot expect something magical with just a simple function that doesn't take any parameter!)
I just wondered what this function could be useful for (sound processing).
