CHORUS EFFECTOR WITH NATURAL FLUCTUATION IMPORTED FROM SINGING VOICE

摘要

A chorus apparatus is constructed for creating a chorus sound toaccompany a vocal sound which is sung by a singer. In the chorus apparatus, aproviding device provides music information including reference pitchinformation which indicates a regular variation of an actual pitch of the vocalsound and harmony pitch information which determines a harmony pitch of thechorus sound. A detecting device detects the actual pitch of the vocal soundcontaining the regular variation and an irregular fluctuation which overlaps theregular variation. A controlling device extracts the irregular fluctuation of theactual pitch from the vocal sound according to the reference pitch information,and modifies the harmony pitch information to impart thereto a desiredfluctuation corresponding to the irregular fluctuation extracted from the vocalsound. A generating device operates according to the modified harmony pitchinformation for generating the chorus sound containing the desired fluctuationover the harmony pitch. A mixing device mixes the vocal sound and the chorussound with each other.
