Ever wonder how video games get their sound effects? We go behind the scenes of Halo, one of the world's most popular video games, to find out how the game builds everything from its weapon sound effects to its sci-fi environment. Creating the sound effects for the latest release, Halo Infinite, required creative foley and field recording techniques to capture and distort real-world sounds that they can then use out of context in the game. Halo Infinite's lead sound designer Kyle Fraser and senior sound designers Robbie Elias and Jomo Kangethe break down the techniques used in destinations as far-flung as Tasmania, an airport runway, and a vintage farm machinery heritage site. They walk us through the sound effects for vehicles, weapons, and destruction in the game, along with the detailed ambiance and environmental sound for the multiplayer maps.—Anonymous
