The present invention executes control of a sound field by controlling respective virtual sound source positions of ambient sound sources and a primary sound source, which are separated audio signalsacquired from an input sound source, in accordance with the change of the speed or the traveling direction of an automobile. This audio signal processing device has: a speed information acquisition unit that acquires speed information of a moving device; a steering information acquisition unit that acquires steering information of the moving device; and an audio control unit that controls output sounds from speakers arranged at a plurality of different positions in the moving device. The audio control unit executes control of the sound field by controlling the virtual sound source positions ofthe ambient sound sources and the primary sound source, which are separated audio signals acquired from the input sound source in accordance with the speed information acquired by the speed information acquisition unit and the steering information acquired by the steering information acquisition unit.
本发明根据汽车的速度或行进方向的变化,通过控制作为从输入声源获取的分离音频信号的环境声源和主声源的各个虚拟声源位置来执行对声场的控制。该音频信号处理装置具有:获取移动设备的速度信息的速度信息获取单元;获取移动设备的转向信息的转向信息获取单元;以及控制来自被布置在移动设备中的多个不同位置处的扬声器的输出声音的音频控制单元。音频控制单元根据由速度信息获取单元获取的速度信息和由转向信息获取单元获取的转向信息,通过控制作为从输入声源获取的分离音频信号的环境声源和主声源的虚拟声源位置来执行对声场的控制。
