    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.
