Method for separating a mixture of source signals to regain said source signals, said method being based on measured signals. The method being characterized in, that every measured signal is brought to a separation structure comprising cross connected linear filters and subsequent adders, that cross correlation functions between the signals after said adders are calculated for delays k between a first delay K1 and a last delay K2, that a criterion function is used to determine how the linear filters comprised in said separation structure will be designed in every real situation, that said criterion function is formulated as a sum of terms where the addition is extended to all possible cross correlation functions between the output signals of separation structure at all possible delays (k) between K1 and K2, and that each term in said sum has a weight factor and another factor consisting of an even function, f, of a specific cross correlation function at a specific delay.
