Abstract
A karaoke sound processor that automatically adjusts to the pitch of the singer's voice is provided. The pitch of the song signal recorded in the accompaniment recording medium for karaoke is detected by a first pitch detecting facility. The pitch of the song signal of the singer entered from the microphone is detected by a second pitch detecting facility. The two song signal pitches are compared in a comparing facility. When the pitches of the two signals are different, the output signal of the accompaniment is automatically changed by a pitch changing facility. The output signal of the pitch changing means and the signal of the microphone are summed up by an adder and produced. Without requring the singer to set the pitch change value, a karaoke sound processor capable of correcting the pitch automatically to a register comfortable for the singer is provided.
