Dolby Atmos, which can blast 128 separate channels at a time, marks the first overhaul since the company debuted Dolby Surround 7.1 with "Toy Story 3" in 2010. The company's president, Kevin Yeaman, said Dolby experimented with adding even more channels but decided it needed a way to render sounds in space, not just put more speakers into theaters.
"We are really responding to a pull in the market from creatives and exhibitors," said Yeaman. "When 3-D hit screens, we started getting questions from people like, 'Now that we're having a more emotional visual experience, what can you do with sound to really bring us into that?' When you combine those two elements, that's a really powerful experience."
