Wiener Filter for Noisy Speech Enhancement

File Information

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

MATLAB release MATLAB 7.0.1 (R14SP1)

it works good as far as noise is almost stationary. Performance also depends on how accurately you determine the number of initial silent segments.
