This video provides a behind-the-scenes look at how the sound effects for the video game Halo 3 were created. The sound designers explain and demonstrate their process, which often involves recording real-world objects and then manipulating the audio.

Here are some of the examples shown:

• Water Footsteps: A sound designer recorded the sound of footsteps in water by running along a beach in Mexico with a stereo microphone, much to the confusion of other beachgoers.
• Warthog Hubcap Sound: Foley artists are shown smashing rocks and hitting metal objects with a hammer in a studio to create the sound effect for the Warthog's hubcap.
• Covenant Force Field Door: The sound of a Subaru hatchback opening was recorded. Its rising pitch was then manipulated to create the futuristic sound of the Covenant force field doors in the game.
• Mongoose ATV Engine: The team recorded the distinct engine sound of a Pontiac Fiero with a modified dual exhaust. This recording was then mixed with a two-stroke engine sound to create the final engine noise for the Mongoose ATV vehicle in the game.
