FIELD: radio engineering. ^ SUBSTANCE: invention relates to device and method of multi-channel noise signal processing and, particularly, to the method compatible with stereosonic method. Device is proposed where output signal and additional parametrical information is used. Besides, input signal includes input channel 1 and 2, derived from initial multi-channel signal. Additional parametrical information describing interactions between channels of initial multi-channel signal use main channel for synthesizing (324) output channels 1 and 2 from the one side of assumed listener disposition. Output channels differ from each other by coherence criterion. Coherence between main channels (for example, left and left restored channel of environmental sound) will decrease due to calculation (322) of the main channel for one of those channels by means of input signals combination. In addition, combination is determined by coherence criterion. ^ EFFECT: effective restoration of multi-channel signal due to reduction of distortions. ^ 25 cl, 25 dwg |
