THREE-DIMENSIONAL (3D) AUDIO CONTENT SAOC STEP-DOWN MIXING IMPLEMENTATION DEVICE AND METHOD Russian patent published in 2018 - IPC G10L19/08 H04S3/00 

FIELD: electrical communication equipment.

SUBSTANCE: invention relates to the three-dimensional audio content SAOC step-down mixing implementation means. Receiving the transport audio signal consisting of two or more audio object mixed signals. Number of transport audio channels is less than the number of audio object signals. Transport audio signal depends on the first mixing rule and the second mixing rule. First mixing rule indicates how to mix two or more audio object signals to produce plurality of pre-mixed channels. Second mixing rule indicates how to mix plurality of pre-mixed channels to produce the transport audio signal one or more transport audio channels. Receiving information about the second mixing rule. Calculating the output channel mixing information depending on the number of audio objects, the number of pre-mixed channels and information on the second mixing rule. Generating one or more audio output channels from the transport audio signal depending on the output channel mixing information.

EFFECT: increase in the audio content step-down mixing efficiency.
