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.
Claims8
An audio device comprising:
- a signal input interface configured to input an audio signal;
- a first output interface;
- a second output interface;
- at least one processing circuit configured as a buffer control portion;
- and
- at least one memory configured to store the audio signal and instructions that, when executed by the at least one processing circuit, wherein:
- the buffer control portion sets a first reading position being a reading position of the audio signal stored in the memory with respect to the first output interface, and a second reading position being a reading position of the audio signal stored in the memory with respect to the second output interface and being a position that precedes the first reading position by delay time;
- and
- the buffer control portion, when starting output of the audio signal, writes silent data for the delay time in the memory with respect to the first output interface and sets the first reading position at a head of the silent data.
A synchronous reproduction method comprising:
- inputting an audio signal;
- storing an input audio signal;
- and
- when starting output by reading a temporarily stored audio signal from a first reading position and a second reading position, writing silent data for delay time in front of the temporarily stored audio signal, setting the first reading position at the head of the silent data, and setting the second reading position at a position that precedes the first reading position by the delay time.
