This invention provides an audio reproducing apparatus which reproduces plural digital audio signals and synchronizes them with each other. The audio reproducing apparatus includes a synchronization setting unit 11 which synchronizes the plural audio signals by allocating, on a time axis, plural pieces of audio reproduction time information of the audio signals and in a manner which maintains a difference between reproduction times indicated by adjacent pieces of the audio reproduction time information of each of the audio signals, and an audio synthesis unit 6 which synthesizes the plural audio signals using the plural pieces of the audio reproduction time information allocated on the time axis.
