PROBLEM TO BE SOLVED: To eliminate a delay between the output timing of the performance sound of music and the output timing of the input singing voice.SOLUTION: A performance control part 16 generates a performance sound of music. A headphone amplifier 19 causes the generated performance sound to be output from a headphone 12 used by a singer. A speaker amplifier 20 causes the generated performance sound and the singing voice input by a voice control part 14 to be output from a speaker 13 capable of being heard by a listener. A point rating control part 15 specifies a delay time between the timing of the generated performance sound and the timing of the singing voice corresponding to the performance sound. A performance delay control part 18 calculates an addition time Tx for delaying the performance sound based on the delay time specified by the point rating control part 15. The performance delay control part 18 delays the performance sound generated with the performance control part 16 by the addition time Tx so as to be output to the speaker amplifier 20 and outputted from the speaker 13.SELECTED DRAWING: Figure 1 |
