PROBLEM TO BE SOLVED: To reduce the processed amount of sound signals by performing virtual sound image orienting processing on composite sound source signals obtained by compositing sound source signals with each other. SOLUTION: M (M: a plural) pieces of sound source signals T1, T2, T3, and T4, each having at least one piece of information selected from among three pieces of information regarding position, movement, and orientation are composited into sound source signals SL and SR of a number smaller than that (M) of the signals T1, T2, T3, and T4 based on the information, and at the same time, the pieces of information corresponding to the composited sound source signals SL and SR are composited. Then the virtual sound image orienting processing is performed on the N pieces of composited sound source signals SL and SR having composited information. |
