CONCEPT FOR COMBINATION OF MULTIPLE PARAMETRICALLY CODED AUDIO SOURCES Russian patent published in 2010 - IPC H04S5/00 G10L19/00 

FIELD: information technologies.

SUBSTANCE: multiple parametrically coded audio signals are combined using generator (100) of audio signal, which generates output audio signal (120) by combination of channels (110a, 112a) of step-down mixing and related parametres (110b, 112b) of audio signals directly within the limits of parametre values areas, i.e. without reconstruction or decoding of separate input audio signals prior to formation of output audio signal (120). It is achieved by direct mixing of related channels (110a, 112a) of step-down mixing of separate input signals. One of key criteria of the present invention consists in the fact that combination of channels (110a, 112a) of step-down mixing is achieved by simple computational efficient arithmetic operations.

EFFECT: possibility of efficient combination of transmitted audio flows.
