Abstract:
1. An audio signal processing device for generating audio signals by arranging objects in a virtual three-dimensional space and performing, at a prescribed listening position, audio simulation to sounds produced from a prescribed sounding position; wherein said audio signal processing device comprises audio signal processing means for performing said audio simulation by structuring a sound field space, which is subject to said audio simulation, by combining spatial objects; wherein said audio signal processing means generates said audio signals by dividing said audio simulation into direct sound, primary reflected sound, high-order reflected sound, and respectively performing simulation thereto; wherein said audio signal processing means generates audio signals of said direct sound pursuant to distance data between said sounding position and listening position, and said medium parameter; and wherein, when the sounding position moves relatively to the listening position in the sound field space composed of a plurality of spatial objects connected to each other, said audio signal processing means generates audio signals of said direct sound by:
