FIELD: information technologies.
SUBSTANCE: device to modify a sweet spot of a spatial M-channel audio signal comprises a receiver (201) to receive an N-channel audio signal, N<M, a parametric facility (203) to detect spatial parameters of step-up mixing, connecting the N-channel audio signal with the spatial M-channel audio signal, a modifying facility (207) to modify the sweet spot of the spatial M-channel audio signal by modification of at least one of spatial parameters of step-up mixing; a facility of generation (205) to generate a spatial M-channel audio signal by step-up mixing of an N-channel audio signal using at least one modified spatial parameter of step-up mixing.
EFFECT: possibility to manipulate a sweet spot with less complexity.
