METHOD FOR PROCESSING AUDIO SIGNAL

摘要

According to the present invention, an audio signal processing method includes the steps of: receiving a channel signal; receiving the input location information of a pre-installed speaker; setting the location of a target speaker to be the location of an absent speaker; arranging a virtual speaker in the location of the absent speaker on the same layer as the target speaker based on the location information of the pre-installed speaker; rendering a channel signal corresponding to the location of the target speaker based on the virtual speaker arranged in the previous step; and down-mixing the rendered channel signal and another channel signal corresponding to the pre-installed speaker. The channel signal includes another channel signal corresponding to the absent speaker.
