Document Type and Number:
WIPO Patent Application WO/2012/169808
Kind Code:
A3
Abstract:
An audio signal processing method includes the steps of: when a first plurality of input channels are down-mixed to a second plurality of output channels, comparing locations of the first plurality of input channels with locations of the second plurality of output channels; down-mixing channels having the same locations as those of the second plurality of output channels from among the first plurality of input channels to channels at the same locations from among the second plurality of output channels; searching for at least one adjacent channel with respect to each of the remaining channels from among the first plurality of input channels; determining a weight for the searched adjacent channel by considering at least one of a distance between channels, a signal correlation, and an error in restoration; and down-mixing each of the remaining channels of the first plurality of input channels to the adjacent channel on the basis of the determined weight.
