PROBLEM TO BE SOLVED: To achieve a reproduction device for efficiently performing processing for generating an audio output signal from multiple audio data which are compression-encoded, respectively. SOLUTION: A first DSP 301 includes a decoding function corresponding to multiple types of compression encoding systems, and decodes main audio data compression-encoded by using one arbitrary type among the multiple types of compression encoding systems. A second DSP 302 includes the decoding function corresponding to the multiple types of compression encoding systems, respectively, and decodes sub-audio data compression-encoded by using one arbitrary type among the multiple types of compression encoding systems. A third DSP 303 performs a mixing processing for mixing a digital audio signal output from the first DSP and the digital audio signal output from the second DSP 302 so as to generate a digital audio output signal.
