PROBLEM TO BE SOLVED: To provide a playback apparatus, capable of improving an S/N characteristic of a one-bit audio signal. SOLUTION: The playback apparatus detects data array section, showing silence from the one-bit audio signal of an original data and sums an analog data into which the data reversed from that in the detected section has been D/A converted, so that an analog data, into which the one-bit audio signal of the original data has been D/A converted, attenuate with the amplitude being a half.
