IMPROVED METHOD FOR CODING AND PARAMETRIC PRESENTATION OF CODING MULTICHANNEL OBJECT AFTER DOWNMIXING Russian patent published in 2013 - IPC G10L19/00 

FIELD: information technology.

SUBSTANCE: audio object encoder, designed to generate encoded object signals using a plurality of audio objects, which includes a downmixing data generator which generates downmixing parameters, having indications for the order of distribution of the plurality of audio objects on at least two downmixing channels, an audio object parameter generator which generates audio object parameters, and an output interface which generates an imported output audio signal using downmixing data and object parameters. An audio synthesiser, which uses downmixing data to generate output data, used to form a plurality of output channels for reproducing an audio signal of a given configuration.

EFFECT: facilitating upmixing on all downmixing channels.
