AUDIO DEVICE AND AUDIO PROVIDING METHOD Russian patent published in 2019 - IPC H04S5/02 H04R5/02 

FIELD: data processing; physics.

SUBSTANCE: invention relates to means of providing an audio device with audio. Audio signal including a plurality of channels is received. Method includes applying to an audio signal having a channel from a plurality of channels causing a sensation of lifting, a filter in order to form a plurality of virtual audio signals which must be respectively output to a plurality of speakers. Combined amplification values and the delay values to the plurality of virtual audio signals are applied such that a plurality of virtual audio signals respectively output through the plurality of speakers form a sound field having a flat wave. Multiple virtual audio signals are output, to which a combined amplification value and a delay value are applied through a plurality of speakers. Filter processes the audio signal so that it has a sensation of lifting.

EFFECT: technical result is to expand the area in which the virtual audio signal can be listened.
