Audio apparatus and audio providing method thereof

摘要

An audio apparatus and an audio providing method thereof are provided. The audio providing method of the audio apparatus comprises: receiving an audio signal including a plurality of channels; generating a plurality of virtual audio signals to be output to a plurality of speakers by applying an audio signal including a channel having a sense of elevation, among the plurality of channels, to a filter for processing the audio signal to enable the audio signal to have the sense of elevation; applying a synthetic gain value and a delay value to the plurality of virtual audio signals in order to form a sound field in which the plurality of virtual audio signals output through the plurality of speakers have a plane wave; and outputting the plurality of virtual audio signals to which the synthetic gain value and the delay value are applied, through the plurality of speakers.
