PROBLEM TO BE SOLVED: To control reproduced sounds so that the reproduced sounds can be delivered only to an operator at all the time even when the position of the operator is changed. SOLUTION: Based on the position information of an operator 1 detected by a sensor part 2 for detecting the position of the operator 1 in real time, a directivity characteristic calculating part 3 calculates directivity characteristics required for delivering the reproduced sounds only to the operator 1. According to the instruction of the directivity characteristic calculating part 3, a signal processing part 4 adds the directivity characteristics to regenerative signals by performing signal processing. A part 5 is a reproducing part for reproducing the regenerative signals processed by the signal processing part 4. Thus, the audio processor can be provided so that the reproduced sounds can be delivered only to the operator by changing the directivity of reproduced sounds while following up a change even when the position of the operator is changed. |
