Abstract: An audio device includes a signal input interface, a first output interface, a second output interface, at least one processing circuit configured as a buffer control portion, at least one memory configured to store an audio signal. The buffer control portion sets a second reading position at a position that precedes a first reading position of the first output interface by delay time, and, when starting output of the audio signal, writes silent data for the delay time in the memory and sets the first reading position at the head of the silent data.

Abstract: An output control device includes a signal input unit configured to receive an audio signal; a first output unit configured to output the audio signal to a first reproducing device; a second output unit configured to output the audio signal to a second reproducing device via communication in which a delay of a first delay time period occurs; and a buffer unit configured to temporarily store the audio signal, to read the temporarily-stored signal, and to output the read signal to the first and the second output units. The buffer unit is configured to advance a second read position, which is a read position in the buffer unit of a buffer signal to be output to the second output unit, by the first delay time period ahead of a first read position, which is a read position of a buffer signal to be output to the first output unit.
