The Squelchy, Messy Art of Video Game Sound Effects

"Step into my office," says Joanna Fang. OK, but to the untrained eye it's a kleptomaniac's hoard: rolls of Astroturf, mud and moss, wooden planks, violin bows, smashed keyboards, plastic boxes brimming with shoes, a full armory of axes and swords, a sand pit, a bamboo fence, rocks, half a bike, smashed iPhones, a boat's anchor chain, a grimy car door. "Never trust a clean foley stage," she says. Fang is a senior foley artist at Sony PlayStation. Her job is to put sound to video games.
