FIELD: physics.
SUBSTANCE: device includes a downmixer for downmixing one or more audio objects to produce one or more raw downmix signals, a processing unit for processing one or more raw downmix signals to produce one or more processed downmix signals, a signal calculating unit for calculating one or more additional signals, the signal calculating unit being configured to calculate each from one or more additional signals based on the difference between one of the one or more processed downmixed signals and one of one or more raw downmixed signals, an object information generator for generating parametric information of audio objects for one or more audio objects and parametric additional information for the additional signal.
EFFECT: improving the playback quality of target audio scenes.
