Vocal effects are techniques used to modify or enhance the sound of a person's voice. These effects can be achieved through various methods, including digital processing, vocal techniques, and the use of equipment like microphones and mixers. Common vocal effects include reverb, echo, and pitch shifting, which can create a unique sound or atmosphere in music and performances. In music production, artists often use vocal effects to add depth and character to their recordings. For example, auto-tune is a popular effect that corrects pitch inaccuracies, while distortion can give a voice a gritty texture. These effects are widely used in genres like pop, rock, and electronic music.
