Music game system, computer program of same, and method of generating sound effect data

Abstract

A music game system ( 1 ) is provided with a sound input device ( 9 ) which inputs sound, a speaker ( 8 ) which outputs game sound, and a external storage device ( 20 ) which stores sound effect data ( 27 ) to cause the speaker to output each of sound effects of different musical intervals and sequence data ( 29 ) in which a relationship between a player's operation and the sound effect to be output correspondingly is described. The music game system determines the musical interval representing an input sound based on sound data of the sound input by the sound input device ( 9 ), generates multiple tone data which have different music interval from the sound data respectively based on the musical interval determination result so as to form the musical scale, and stores a set of multiple tone data as at least a part of the sound effect data ( 27 ).

1 . A music game system comprising:
 a sound input device which inputs sound;   an audio output device which outputs game sound;   a sound effect data storage device which stores sound effect data to cause the audio output device to output each of sound effects of different musical intervals;   a sequence data storage device which stores sequence data in which a relationship between a player's operation and the sound effect to be output correspondingly is described;   a musical interval determination device which determines the musical interval representing an input sound based on sound data of the sound input by the sound input device;   a musical scale generating device which generates multiple tone data which have different music interval from the sound data respectively based on a musical interval determination result of the musical interval determination device so as to form the musical scale; and   a sound effect data storage control device which causes the sound effect data storage device to store the multiple tone data generated by the musical scale generating device as at least a part of the sound effect data.   
     
     
         2 . The music game system of  claim 1 , wherein
 the musical interval determination device determines the musical interval of the sound by identifying a frequency representing the sound data of the sound input by the sound input device.   
     
     
         3 . The music game system of  claim 1 , wherein
 the musical scale generating device generates the musical scale of at least one octave or more.   
     
     
         4 . The music game system of  claim 1 , further comprising:
 an input device which has at least one operating device; wherein   the sound effect following a description of the sequence data is played by the audio output device based on operations of the player through the input device.   
     
     
         5 . A storage medium storing a computer program for a music game system comprising:
 a sound input device which inputs sound;   an audio output device which outputs game sound;   a sound effect data storage device which stores sound effect data to cause the audio output device to output each of sound effects of different musical intervals;   a sequence data storage device which stores sequence data in which a relationship between a player's operation and the sound effect to output correspondingly is described; wherein   the computer program causes the music game system to function as:   a musical interval determination device which determines the musical interval representing an input sound based on sound data of the sound input by the sound input device;   a musical scale generating device which generates multiple tone data which have different music interval from the sound data respectively based on a musical interval determination result of the musical interval determination device so as to form the musical scale; and   a sound effect data storage control device which causes the sound effect data storage device to store the multiple tone data generated by the musical scale generating device as at least a part of the sound effect data.   
     
     
         6 . A method of generating sound effect data comprising:
 a musical interval determination step which determines the musical interval representing an input sound based on sound data of the sound input by a sound input device;   a musical scale generating step which generates multiple tone data which have different music interval from the sound data respectively based on a musical interval determination result of the musical interval determination step so as to form the musical scale; and   a storing step which causes a storage device to store the multiple tone data generated by the musical scale generating step as sound effect data for outputting from an audio output device.
