PROBLEM TO BE SOLVED: To provide a technique for reducing a load of processing for evaluating singing in Karaoke. SOLUTION: In a microphone device 15, a plurality of microphones 150 execute sound pickup of singing sound and generate sound signals in respectively different frequency band ranges. The plurality of sound signals are analyzed, and the characteristic of each frequency component is extracted in a characteristic information extraction part 154. The plurality of sound signals are mixed in a mixing part 157 and the sound signal representing original singing sound is generated, and a modulation wave modulated based on the characteristic information is superimposed on the mixed sound signal in a superimposition part 158.
