Abstract
A playback device includes a first generator, a second generator and a combiner. The first generator processes main audio data to output first audio data. The second generator processes additional audio data to output second audio data. The combiner combines the first audio data with the second audio data. While a sampling frequency of the main audio data is different from a sampling frequency of the additional audio data, the second generator generates the second audio data to adjust a playback speed of the additional audio data based on the sampling frequency of the main audio data.
