SOUND PROCESSING DEVICE AND METHOD, AND PROGRAM THEREFOR Russian patent published in 2019 - IPC H04S5/02 H04R1/20 

FIELD: data processing.

SUBSTANCE: invention relates to audio processing. Listening position information of the user is received, which indicates the user's listening position where the sound from the sound source is listened. Sound source first position information is received, which indicates the first position of the sound source relative to the standard listening position. Based on the first position of the sound source and the listening position of the user, the sound source second position information is calculated, which indicates the second position of the sound source relative to the listening position of the user. First position information and second position information of the sound source are expressed by spherical coordinates. Frequency response of the analogue signal of the sound source is adjusted based on a first distance, which is greater than a second distance, wherein the first distance is the distance between the second position of the sound source and the listening position of the user, and the second distance is the distance between the first position of the sound source and the standard listening position.

EFFECT: improved quality of sound reproduction.
