AUDIO PROCESSOR AND METHOD FOR PROVISION OF LOUDSPEAKER SIGNALS Russian patent published in 2023 - IPC H04S7/00 H04R27/00 

FIELD: audio processing.

SUBSTANCE: invention relates, in general, to audio processors for rendering of audio, in which a sound follows a listener. The audio processor for provision of a set of loudspeaker signals or supply of a sound to loudspeakers based on a set of input signals, such as channel signals and/or object signals, is made with the possibility of reception of information relatively to a position of a listener and a position of a set of loudspeakers or sound converters, which can be placed in the same compartment, for example in a sound bar. The audio processor is additionally made with the possibility of dynamic adaptation of isolation of objects, and/or channel objects, and/or adapted signals, such as adapted channel signals, extracted from input loudspeaker signals, such as channel signals or channel objects or such as signals mixed with an increase or mixed with a decrease. Adaptation of location depends on information relatively to the position of the listener and on information relatively to positions of loudspeakers. In other words, the audio processor determines, which loudspeakers should be used in rendering of different channel objects or adapted signals. The audio signal processor is additionally made with the possibility of rendering of objects, and/or channel objects, and/or adapted signals extracted from input signals, depending on information relatively to the position of the listener, on information relatively to positions of loudspeakers, and depending on the mentioned isolation, to obtain loudspeaker signals in such a way that a rendered sound follows the listener.

EFFECT: optimization of audio playback and audio signal rendering for formation of reliable and pleasant auditory impression of a listener.
