Claim Text:
1. Arrangement for mixing at least two audio signals, comprising: inputs for receiving the at least two audio signals, a first unit for deriving a first power signal, which first power signal is a measure for the power of the first audio signal, a second unit for deriving a second power signal, which second power signal is a measure for the power of the second audio signal, a cross-correlation unit for deriving a cross-correlation signal, which is a measure of the cross-correlation between the first and second audio signal, a unit for deriving at least one multiplication parameter from the first and second power signals and the cross-correlation signal, a multiplication and combination unit for carrying out a signal processing on the first and second audio signals, which is equivalent to: wherein the unit for deriving a multiplication parameter is provided with a combination unit for deriving a combination signal which is a measure for the combination of the first and second power signals and the cross-correlation signal, and provided with a scaling unit for scaling a signal component in the unit for deriving a multiplication parameter with a scaling signal, that the scaling signal (D[k]) has a frequency characteristic which is substantially constant in a frequency range below a first frequency value (k
