PROBLEM TO BE SOLVED: To provide an audio encoding device that can improve encoding efficiency without lowering sound quality. ! SOLUTION: An audio encoding device includes a calculation section that calculates the similarity of phases of a first channel signal and a second channel signal included in a plurality of channels of an audio signal. In addition, the audio encoding device includes a selection section that selects, on the basis of the similarity, a first output that outputs one of the first channel signal and the second channel signal, or a second output that outputs both of the first channel signal and the second channel signal. !
