<p>In an application system requiring real time performance, an audio processing system is provided whereby the hardware cost is reduced, the burden of developing control programs is reduced, the problems associated with performance degradation and so forth are minimized, and the signal processor keeps track of the output status of the data. The audio processing device (100) comprises an additional information superimposition unit (113) which superimposes, as the additional information onto the audio data, control information which is different from audio information; and an additional information detection unit (150), connected to a data bus connecting a memory (120) and the audio data output circuit (140), which detects the additional information (200) added to the audio data. The additional information detection unit (150) outputs the additional information (200) that is detected to the output control unit (111) of the signal processor (110) through an additional information detection status readout channel (117). The output control unit (111) controls the output of audio data on the basis of the additional information (200) detected by the additional information detection unit (150).</p> |
