<p>An audio signal processing device includes a digital stream signal processing device which outputs a multi channel surround sound stereo signal as an FL-FR stream signal which includes front L and R signal components and an SL-SR stream signal which includes surround L and R signal components. Moreover, this audio signal processing device includes a selector circuit which selects and outputs either one of the FL-FR stream signal and the MIXL-MIXR stream signal, based upon a two channel sound / multi channel sound changeover signal. And this audio signal processing device also includes a D/A converter which outputs the output of the selector circuit as front L and R analog signals.
