<P>PROBLEM TO BE SOLVED: To enhance a feeling of playing a sound by a player himself/herself by acoustically dividing a pseudo backtrack sound from a player's input sound. <P>SOLUTION: This game device is provided with backtrack sound data 61, player's input sound data 72 which are music sound data 62 and reproduced according to the input of the player, and the pseudo backtrack sound data 72 which are the music sound data 62 and excluded from the player's input sound data 71. The device stores sound volume change rate information formed by linking types of musical instruments corresponding to the music sound data 62 with the change rate of the reproduction sound volume. The device determines the type of the corresponding musical instruments based on the player's input sound data 71 or the pseudo backtrack sound data 72 and determines the change rate of the reproduction sound volume of either one of the player's input sound data 71 or the pseudo backtrack sound data 72 based on the determined type of the musical instrument and the sound volume change rate information. The game device reproduces the player's input sound data 71 or the pseudo backtrack sound data 72 at the appropriate sound volume. <P>COPYRIGHT: (C)2004,JPO |
