GameSetWatch received a press release today from Audiobrain, which is the sound design company, headed by long-time gameLab composer Michael Sweet, behind the built-in sounds for the Xbox 360.

The release handily explains of Xbox 360's epic opening swooooosh: "The startup [noise], created with several layers of clear and consistent sound design, both organic and architectural in nature, starts with a rumble representing the enormous size of the world appearing over the horizon, then a swoosh for the energy and a shimmer with lower sounds colliding at the visual impact and form the X in the world, creating the sense of duality and searing, impactful energy." Yep, it sounds better in Dubly, especially after that explanation - the specially composed Xbox 360 soundtrack for the console's E3 appearance also plays on the Audiobrain homepage.
