Abstract
This encoding device comprises: a downmix circuit that switches mixing processing according to the characteristic of an input stereo signal to generate either a first stereo signal or a second stereo signal obtained by mixing processing of a left channel signal and a right channel signal; a first encoding circuit that encodes the first stereo signal; and a second encoding circuit that encodes two signals included in the second stereo signal. The second encoding circuit performs monaural encoding on the basis of the encoding mode of the first encoding circuit in a first section in which switching from the first stereo signal to the second stereo signal is performed and/or a second section in which switching from the second stereo signal to the first stereo signal is performed.
