    Abstract: When a channel signal, such as a 22.2 channel signal, is rendered into a 5.1 channel signal, a three-dimensional (3D) audio may be reproduced by using a two-dimensional (2D) output channel, however, when an elevation angle of an input channel is different from a standard elevation angle, if elevation rendering parameters according to the standard elevation angle are used, distortion may occur in a sound image. In order to solve the aforementioned problem according to the related art and to prevent front-back confusion due to a surround output channel, an embodiment of the present invention provides a method of rendering an audio signal, the method including receiving a multichannel signal including a plurality of input channels to be converted to a plurality of output channels; adding a preset delay to a frontal height input channel so as to allow each of the plurality of output channels to provide a sound image having an elevation at a reference elevation angle; changing, based on the added delay, an elevation rendering parameter with respect to the frontal height input channel; and preventing front-back confusion by generating, based on the changed elevation rendering parameter, an elevation-rendered surround output channel delayed with respect to the frontal height input channel.

    Abstract: An audio apparatus and an audio providing method thereof are provided. The audio providing method includes receiving an audio signal including a plurality of channels, applying an audio signal having a channel, from among the plurality of channels, giving a sense of elevation to a filter to generate a plurality of virtual audio signals to be respectively output to a plurality of speakers, applying a combination gain value and a delay value to the plurality of virtual audio signals so that the plurality of virtual audio signals respectively output through the plurality of speakers form a sound field having a plane wave, and respectively outputting the plurality of virtual audio signals, to which the combination gain value and the delay value are applied, through the plurality of speakers. The filter processes the audio signal to have a sense of elevation.
