1. A method of generating an undisturbed signal out of an audio signal including a disturbing signal, comprising:

  • estimating autocorrelation matrices and cross-correlation vectors of the equation of the Wiener filtering problem;

    calculating the coefficients of the solution vector of the equation of the Wiener filtering problem;

    evaluating the quality of the calculated coefficients;

    controlling the estimation step depending on the quality of the calculated coefficients;

    generating a correction signal out of the disturbing signal depending on the calculated coefficients; and

    correcting the audio signal depending on the correction signal.
