Wiener Filter for Noisy Speech Enhancement, implemented as proposed by Scalart 1996. Uses a decision directed method to track the a priori SNR. Note that the first 0.25sec of the signal is used to model the noise, that is, it is assumed that speech starts after that 0.25sec

At this function [output=WienerScalart96(signal,fs,IS)], IS means?
Nice code, it help me a lot. Thanks !
It alters the signal length, making it a little shorter than the original. Why?
I would like to understand this filter, who can explain me, and tell me how to use it on an ECG signal, I'm grateful!
I'm student of department telecommunication electronic
it should be much better..
Very nice demonstration!
I need it, thanks£¡
it works good as far as noise is almost stationary. Performance also depends on how accurately you determine the number of initial silent segments.
