摘要：PROBLEM TO BE SOLVED: To provide a technology capable of realizing highly realistic reproduction by simplifying complex operation for setting a plurality of parameters in a conventional surround creation, and varying the sound in real time. SOLUTION: The invention relates to a sound field reproducing device comprising a signal input means for inputting an acoustic signal of a sounding body, a means for distributing the acoustic signal of the sounding body inputted by the signal input means into two or more channels of acoustic signals based on the positional coordinates of the sounding body located in a virtual space and a view point position to be set to the virtual space and controlling the level of each acoustic signal, a means for generating a reverberation signal in the virtual space based on the acoustic signals distributed to the two or more channels, a means for generating a reproduction signal for the channels each by synthesizing the reverberation signal and the level-controlled acoustic signal, and a means for reproducing the sound field from the supplied reproduction signal.
