1. A method for headphone reproduction of at least two input channel signals, said method comprising for each pair of input channel signals from said at least two input channel signals:
determining a common component, an estimated desired position corresponding to said common component, and two residual components corresponding to two input channel signals in said pair of input channel signals, the determining being based on said pair of said input channel signals, whereby each of said residual components is derived from its corresponding input channel signal by subtracting a contribution of the common component, said contribution being related to the estimated desired position of the common component, synthesizing in the frequency or time domain a main virtual source comprising said common component at the estimated desired position, wherein said synthesized main virtual source is provided as a first output for use in a headphone reproduction system, synthesizing in the frequency or time domain two further virtual sources each comprising a respective one of said residual components at respective first and second predetermined positions, wherein said two further virtual sources are provided as respective second and third outputs for use in said headphone reproduction system, and wherein the estimated desired position represents a spatial position perceived by a user in the headphone reproduction system, the spatial position perceived to be between the two predetermined positions corresponding to said first and second predetermined positions in the headphone reproduction system, wherein the estimated desired position corresponding to the common component is determined depending on power parameters of the corresponding input channel signal, and wherein for a pair of input channel signals said power parameters comprise: a left channel power Pl, a right channel power Pr, and a cross-power Px. |
