PROBLEM TO BE SOLVED: To change the synthesis ratio of sound, automatically and flexibly and output the synthesized sound, when game sound externally input from a mobile game machine and the music sound of music data replayed by music player function of a mobile phone are synthesized and output.SOLUTION: The timing when sound pressure or tempo of the music sound is changed is a timing of high importance for progression of a game, such as, generation of sound effects for games and generation of game events. COnsequently, when the game sound and the music sound are synthesized and output, change in the tempo and sound pressure of the game sound is detected; when there is no change in the sound pressure and the tempo of the game sound, the game sound and the music sound are synthesized, at the synthesis ratio set by a user, in advance, and output; and when the change of the sound pressure greater than a predetermined sound pressure of the game sound is detected, or when a change in the tempo of the game sound is detected, the synthesis ratio of the game sound is set greater than the synthesis ratio of the music sound and then output is made. |
