    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.

    摘要： The object of the present invention is to provide multi-channel reproducing apparatuses and multi-channel reproducing loudspeaker apparatuses that can be easily connected to one another. In the multi-channel reproducing apparatus 1, a DSP 6 converts an inputted audio signal to audio signals for a plurality of channels, adds channel identification information to each audio signal and multiplexes the audio signals to generate a multi-channel reproducing signal. The DSP 6 supplies the multi-channel reproducing signal to a plurality of multi-channel reproducing loudspeaker apparatuses 20 1 to 20 n that are dispersedly arranged. These multi-channel reproducing loudspeaker apparatuses 20 1 to 20 n input the multi-channel reproducing signal from an input terminal 20a and output the signal to outside from an output terminal 20b. Each loudspeaker apparatuses 20 1 to 20 n extracts and reproduces the audio signal of the channel assigned thereto from among the multi-channel reproducing signals inputted from a decoder 11 and outputs audio sound from a loudspeaker 16.
