METHOD, NON-VOLATILE MACHINE-READABLE MEDIUM AND MPEG-H 3D AUDIO DECODER FOR EXTENDING THREE DEGREES OF FREEDOM OF MPEG-H 3D AUDIO Russian patent published in 2024 - IPC H04S7/00 

FIELD: means for processing information on the position of an audio object.

SUBSTANCE: information on the orientation of the head of the listener is obtained. Information on the displacement of the head of the listener relative to the nominal listening position is obtained through the input interface of MPEG-H 3D Audio decoder. Position information contains an indication of the distance from the audio object to the nominal listening position. Position of the object is modified based on the information on the displacement of the listener by applying a translational movement to the position of the object. Modified position of the object is additionally modified based on the information on the orientation of the listener. When the information on the displacement of the listener indicates a slight displacement of the head of the listener, distance between the position of the audio object and the listening position after the displacement of the listener’s head is equal to the distance between the modified position of the audio object and the nominal listening position.

EFFECT: high efficiency of processing information on the position of an audio object.
