To give voices to the frightening monsters in movies, TV shows, and video games, sound designers often start with animal noises, then apply all kinds of creative processing. But other times, these sounds begin with human voice actors, who absolutely shred their vocal cords for our entertainment. In this episode, we learn the tricks of the terrifying trade. Featuring voice actors DB Cooper and Michael Schwalbe, and sound designer/composer Jordan Chin. Follow the show on Twitter, Facebook, & Reddit. Subscribe to our Youtube channel here.
