PURPOSE: To obtain a duet effect having a higher consonancy and a feeling of separation by mixing sound converted into a musical interval by microphone input voices and a setting means so that they have a difference in voice volumes and a fixed difference in the sound images. CONSTITUTION: A voice volume difference is provided for an attenuation circuit 16 before a microphone input voice and another microphone input voice are mixed at an addition circuit 4 through an interval conversion circuit 3 converting a musical interval by an interval conversion setting means 15 capable of setting an interval conversion volume to asinger. Also, the output of the interval conversion circuit 3 is set to a level by another attenuation circuit 17 before a fixed sound image difference is made by mixing the output only with Rch sound output at the addition circuit 9. An echo component of an output from a delay circuit 5 is attenuated to a certain volume or lower at a delay control circuit 19 and added, and thereby a duet effect with a higher consonancy and a feeling of separation can be obtained. |
