Tuner is a tool that enables the user to manipulate audio to put it in a certain key or note. It can be run as an auto turner, or select audio can be modified in specific parts manually. For this project, I selected A Major as the key, to which the effect blacked out the notes that did not pertain to that scale, which allowed me to draw blue lines on my audio lines to adjust them to the note I wanted to hit instead.
Tuner was applied to the forward vocals track.
