How Avengers: Age of Ultron's Skull-Crunching Sounds Were Made

By Mario Aguilar on at

Avengers: Age of Ultron is the kaboom, smash, crunch action movie of the moment. Check out this short documentary about how the sonic magic was made.

The new SoundWorks Collection doc goes deep with Ultron’s Supervising Sound Editor and Sound Designer Christopher Boyes, of legendary Skywalker Sound. Boyes elaborates how he and his team evolved the Hulk’s groaning roars to sound more confused, as well as how Ultron’s sounds were created using layers upon layers of rolling ball-bearing recordings. Plus, for the nerds out there, it’s fun to watch a Pro Tools timeline play with all the tracks stacked up on a screen.

Boyes’s choicest observation concerns the challenge of using the Dolby’s latest and greatest sound technology to try to augment the visual onslaught of the film: “A Marvel Film presents us with a massive amount of visual information, he says, “So it’s not hard to find justification for using the immersive format. But given that there’s so much going on, it’s hard for that immersive format to make a major statement.”
