Abstract
A decoding device includes a decoder configured to separate a first signal obtained by performing down-mix on original signals of a plurality of channels, a residual signal representing a component of a difference between the original signals and the first signal, and spatial information representing the relationship among the original signals of the plurality of channels from an input signal which is obtained by multiplexing the first signal, the residual signal, and the spatial information and decode the separated encoded first signal, the encoded residual signal, and the encoded spatial information; a decorrelation signal generation unit configured to generate a decorrelation signal as decorrelation of the first signal decoded by the decoder; a residual signal determination unit configured to determine whether a level of the residual signal decoded by the decoder is equal to or smaller than a predetermined residual threshold value; a second-signal generation unit.
