The audio lure is a mechanic that came from Five Nights at Freddy's 3 in the form of BB's voice as a way to trick Springtrap into thinking a lonely child is there and that it'll be easier to kill instead ad is also used in FNAF 6 to lure the animatronics in the vents from room to room in the main gameplay while in Ultimate Custom Night they hold the Mediocre Melodies in place. They are referenced in the end by being a "Labrynth."

The Audio Lure can attract all audio duct animatronics, however, in Ultimate Custom Night, it has a 50% chance to fool Nedd Bear and a 10% chance to fool Orville Elephant. Even so, these animatronics can also be repelled using the Heater, at the expense of others being enraged.
