摘要

An audio signal processing apparatus, an audio signal processing method, an audio signal processing program, an audio signal processing system and a photographing apparatus are provided which can appropriately recognize the speech to be observed.An image from a camera (10) photographed from a predetermined position in the observation object area is displayed on a display (112).The position of the observation object is set by accepting the designation of the position in the picture displayed on the display (112).The positional relationship between the set observation object and the plurality of microphones (mij) arranged discretely in the observation object area is calculated.Based on the result of the calculation, the arrival time up to the arrival of each microphone (mij) from the observation object is calculated.On the basis of the result of the calculation, the audio signals from the respective microphones (mij) are simultaneously multiplexed and superimposed, and outputted from the speaker 114.
