    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: In cases of rendering a multichannel signal such as a 22.2 channel signal as a 5.1 channel signal, a three dimensional (3D) audio signal may be reproduced using a two dimensional (2D) output channel, but rendered audio signals are sensitively affected by a layout of speakers and may cause distortion of a sound image when the layout of arranged speakers is different from a standard layout. The present invention may solve the aforementioned problem of the prior art. The audio signal rendering method for reducing distortion of a sound image even when the layout of the arranged speakers is different from the standard layout, according to one embodiment of the present invention, includes: receiving a multi-channel signal including a plurality of input channels that are to be converted to a plurality of output channels; obtaining deviation information about at least one output channel, from a location of a speaker and a standard location corresponding to each of the plurality of output channels; and modifying a panning gain from a height channel included in the plurality of input channels to the output channel having the deviation information, based on obtained deviation information.
