摘要： A spatial sound generation device including a storage (106) and a controller (102) and connected to a plurality of speakers (116) is provided. In the spatial sound generation device, referring to information indicating a movable sounding body, the controller varies a transfer characteristic for each time in accordance with movement of the sounding body and applies an inverse filtering to calculate a plurality of input signals for the respective speakers from a sound source signal indicating a sound emitted by the sounding body. The inverse filtering outputs the input signals into the speakers to form a three-dimensional acoustic wave front under boundary surface control in accordance with a transfer characteristic for a space in which the plurality of speakers are arranged.
