とを特徴とする音程制御装置。WRITE CLOCK writes the singer's voice as its original sound to the memory device in a constant state, and then outputs the WRI signal at the beginning of the song.
READ CLO with the same frequency as TE CLOCK
CK is read out, the frequency of the read signal output and the reference music are compared in a phase comparator circuit, a READ CLOCK with a frequency controlled by the comparison error voltage is created, and the next audio output is read out using this controlled READ CLOCK. By comparing the frequency of the audio output of , and the reference music using a phase comparator circuit, reading out the audio output of the audio, and repeating the same operation, the frequency of the reference music and the frequency of the singer's voice are always matched. A pitch control device characterized by controlling.
