METHOD AND APPARATUS FOR RENDERING SOUND SIGNAL, AND COMPUTER-READABLE RECORDING MEDIUM

摘要

A method of reproducing a multi-channel audio signal including an elevation sound signal in a horizontal layout environment is provided, thereby obtaining a rendering parameter according to a rendering type and configuring a down-mix matrix, and thus effective rendering performance may be obtained with respect to an audio signal that is not suitable for applying virtual rendering. A method of rendering an audio signal includes receiving a multi-channel signal includes a plurality of input channels to be converted into a plurality of output channels; determining a rendering type for elevation rendering based on a parameter determined from a characteristic of the multi-channel signal; and rendering at least one height input channel according to the determined rendering type, wherein the parameter is included in a bitstream of the multi-channel signal.
