FIELD: computer engineering.
SUBSTANCE: technical result is achieved due to the fact that a processed audio scene is formed using a set of parameters and information relative to the transport signal, wherein generation comprises a step of generating a raw representation of two or more channels using a set of parameters and a transport signal, multichannel forming an enhancing representation of two or more channels using a transport signal, wherein multichannel generation comprises a step of generating an enhancing transport signal, upmixing and multichannel filling are performed to generate an enhancing representation of two or more channels using an enhancing transport signal and at least one parameter from a set of parameters, and combining the raw representation of the two or more channels and the enhancing representation of the two or more channels to obtain a processed audio scene.
EFFECT: high accuracy of processing an encoded audio scene.
