AUDIO PROCESSOR AND METHOD TAKING INTO ACCOUNT ACOUSTIC BARRIERS, PROVIDING LOUDSPEAKER SIGNALS Russian patent published in 2023 - IPC H04S7/00 H04R27/00 

FIELD: audio processing.

SUBSTANCE: invention relates to audio processors 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. The audio processor is made with the possibility of reception of information relatively to a listener’s position, as well as relatively to a position of a set of loudspeakers or electroacoustic sound converters, which can be placed in the same compartment, for example in a sound panel. The audio processor is additionally made with the possibility of selection of one or more loudspeakers for rendering of objects, and/or channel objects, and/or adapted signals extracted from input signals, such as channel signals or channel objects, or such as mixed-up or mixed-down signals. Selection of one or more loudspeakers depends on information relatively to the listener’s position, on information relatively to positions of loudspeakers, and it takes into account information relatively to one or more acoustic barriers. In other words, the audio processor determines, which loudspeakers should be used in rendering of different channel objects or adapted signals, taking into account sound attenuation between the loudspeaker and the listener or elongation of an acoustic tract between the loudspeaker and the listener due to barrier properties. 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 listener’s position and depending on information relatively to positions of loudspeakers for reception of loudspeaker signals in such a way that a rendered sound follows the listener.

EFFECT: provision of the best compromise between complexity of sound processing and listener’s audio perception.
