Auto-tuning allows Finn to modulate his voice in a musical way by raising or lowering notes. He gained this ability by swallowing a little computer in an unspecified moment earlier in his life. It was first used in "The Jiggler," in which Finn used it to sing "Baby" to Stanley and a Jiggler. He also used it without singing when he said "Let's get this party started!" to Jake and when he said "Get down!!!" in the same episode.
Episodes used
- "The Jiggler"
- "Freak City"
- "Another Way"
- "Incendium"
- "Dream of Love" (briefly)
- "Davey" (briefly)
Trivia
- Finn can choose whether or not he uses auto-tuning; he sings without it in numerous episodes. However, in "Davey," he rubs his stomach to use auto-tune.
- He can also use auto-tune not only to sing, but to modify his voice, turning it an octave higher or lower, as seen in "Davey."
