PROBLEM TO BE SOLVED: To achieve an information processing unit that provides information that a user can intuitively understand that what pseudo reflected sound is generated.SOLUTION: In a space having a hearing position G as an original point, a voice analyzing section 201 uses, as a distance D, a delay time from a direct sound included in sound field effect information, and displays an image of a pseudo reflected sound in a position determined by a direction from the hearing position G. The size L of the image of a pseudo reflected sound is changed according to the ratio of the level of reflected sound to the level of direct sound. Using input of a predetermined level or higher as direct sound, the voice analyzing section 201 calculates the display position of pseudo reflected sound, and generates an image of the pseudo reflected sound in a calculated display position. For example, if an R channel, L channel, and C channel for an input audio signal simultaneously receive input of a predetermined level or higher, a display position calculated from these direct sounds and the image 501 of a pseudo reflected sound corresponding to the level are generated. |
