IMPROVED METHOD FOR CODING AND PARAMETRIC PRESENTATION OF CODING MULTICHANNEL OBJECT AFTER DOWNMIXING Russian patent published in 2011 - IPC G10L19/00 

FIELD: information technology.

SUBSTANCE: audio object encoder is designed to generate coded signals of audio objects using a plurality of audio objects, where the plurality of audio objects includes a stereo object represented by two audio objects having a defined non-zero correlation, and includes a downmixing information generator (96) for generating downmixing information which reflects the order of distribution of the plurality of audio objects at least between two downmixing channels, an object parameter generator (94) for generating object parameters for audio objects, where object parameters include object energy approximation for the plurality of audio objects and correlation data for the stereo object, and an output interface (98) for generating the coded signal of the audio object using downmixing characteristics and parameters of the object.

EFFECT: possibility of flexible quality control when differentiating objects depending on application requirements and operational properties of the transmission system.
