    Wiener Filter description

    This is a MATLAB implementation of the Wiener Filter for Noisy Speech Enhancement

    It uses a decision directed method to track the a priori SNR signal.

    Requirements:

    · MATLAB 7.0.1 or higher

    Limitations:

    · 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
