<P>PROBLEM TO BE SOLVED: To achieve further simplification and reduction of costs of a circuit configuration in comparison with conventional D/A converters. Ž<P>SOLUTION: A digital audio signal is inputted, first audio data A(T) and second audio data A(-T) delaying the first audio data just by one sampling time are generated, the first audio data A(T) are separated into data L(T) for Lch and data R(T) for Rch, and a first analog signal L(t) and a second analog signal R(t) are generated by performing D/A conversion. The second audio data A(-T) are separated into data L(-T) for Lch and data R(-T) for Rch, and a third analog signal L(-t) and a fourth analog signal R(-t) are generated by performing D/A conversion. An analog signal connecting signal levels between sampling points using the first analog signal L(t) and the third analog signal L(-t) and an analog signal formed from the second analog signal R(t) and the fourth analog signal R(-t) are generated.
