PROBLEM TO BE SOLVED: To enjoy a more interesting chorus that a conventional KARAOKE(a recorded orchestral accompaniment) device does not have when a song is sung by using plural microphones. SOLUTION: Changeover switches SW1-SW4 are switched associatively according to respective operation modes M1-M3. In the mode M1, a vocal sound collected by the microphone 1b is outputted as it is and a vocal sound collected by the microphone 1a is converted into a chorus sound constituting a consonance with the vocal sound and outputted. In the mode M2, the vocal sound collected by the microphone 1a is outputted as it is and the vocal sound collected by the microphone 1b is converted into the chorus sound constituting the consonance with the vocal sound and outputted. In the mode M3, the vocal sounds collected by the microphones 1a and 1b are mixed, the chorus sound is added to the mixed sound, and the resulting sound is outputted. |
