FIELD: physics.
SUBSTANCE: invention relates to computer equipment for audio processing. Technical result is achieved by collecting metadata containing position information indicating position of audio object, and sound image information made of a two-dimensional or more vector and representing the length of the audio image when viewed from said position; computing, based on the angle in the horizontal direction and the angle in the vertical direction, the region representing the length of the audio image, the determined sound image information, the spread vector indicating the position in the region; and calculating, based on the spread vector, the gain of each of the audio signals supplied to the two or more audio output units located near the position indicated by the position information.
EFFECT: technical result consists in improvement of accuracy of audio processing to produce sound of high quality.
