FIELD: acoustics.
SUBSTANCE: invention relates to devices for providing upmix signal representation based on downmix signal representation. Device includes distortion limiter formed to obtain modified imaging matrix using user-defined imaging matrix linear combination and specified imaging matrix depending on linear combination parameter. Device also includes signal processor, generated, to obtain upmix signal representation based on downmix signal representation and associated with parametric information object using modified imaging matrix.
EFFECT: technical result consists in provision of high sound quality even in case of audio encoding matrix user selection while maintaining low level of computational efficiency on audio encoder side.
