<P>PROBLEM TO BE SOLVED: To make sound by correcting off-key of a tone pitch and a volume of a singer by making a sound signal which is output from a microphone, closer to the sound signal of a reference of accompaniment music used as a model. <P>SOLUTION: A central processing unit (CPU) and a digital signal processor (DSP) extract a parameter of a sound signal which is input from the microphone, and inputs the parameter of the sound signal of the reference as a musical instrument digital interface (MIDI) data, and calculates weighing of a combination ratio of values of the extracted parameter and the input parameter. According to the value of the extracted parameter based on the calculated weighting, and the value of the input parameter, corresponding sound is synthesized and transmitted to a sound system. <P>COPYRIGHT: (C)2007,JPO&INPIT |
