IMMERSIVE AUDIO STEREO SYSTEM Russian patent published in 2024 - IPC G10K15/00 

FIELD: acoustics.

SUBSTANCE: invention, in the form of an acoustic stereo system, relates to surround sound transmission systems. More specifically to immersive audio systems, which enable to form an acoustic image at any point in space around the listener. This method can be used both in cinemas and at home. An acoustic stereo system in the form of two loudspeakers with wideband high-accuracy radiators is placed on the same line on the left and right lateral sides and at the same level from the listener’s head, deployed by the radiators at right angles so that the listener is in the acoustic focus area. It is also allowed to use a separate low-frequency loudspeaker in any place of the room. A stereo signal in the form of a binaural phonogram obtained by recording onto binaural microphones, in which the head transfer function is fully involved, is transmitted from a Hi-Fi reproduction device to loudspeakers, through a wire or wireless transmission channel, and the quality of the phonogram must not be lower than the Audio CD standard.

EFFECT: providing accurate spatial localization of sound objects around a listener from any direction.
