摘要：
The present invention relates to an audio signal output device for outputting based on a digital audio signal. A judging unit judges the frequency of reversals in polarity of the digital audio signal. A selecting unit switches an output of the audio signal output device between an output based on a first interpolated digital audio signal obtained by interpolating the digital audio signal by way of a first interpolation processing and another output based on a second interpolated digital audio signal obtained by interpolating the digital audio signal by way of a second interpolation processing in response to a judgment result made by the judging unit.
