The bass extension is also impressive, not just with obvious effects like tanks and explosions but also with the gunfire. Even though the guns sometimes have suppressors on them, there's still a low-end kick to remind you how powerful the ordinance is and their affect on the human body. However it's the climatic sandstorm that makes American Sniper such a stand-out Atmos soundtrack, as all the speakers and the subs burst into life, completely enveloping you and making the entire sequence remarkably visceral. Having seen Everest at the cinema, we knew we were in for a treat and the Dolby Atmos-encoded Blu-ray certainly didn't disappoint.

The sound designers take full advantage of the object-based capabilities of Atmos to create a completely believable soundstage that really adds to the veracity of the film. Like the narrative itself, the sound design slowly builds creating an utterly believable sense of location that works perfectly with the equally impressive visuals. As the climbers ascend the mountain, so the soundtrack builds, adding more audio cues from the wind constantly moving around the entire soundstage to the footsteps crunching snow to the ice creaking and cracking. However once the storm arrives, the sound design goes into overdrive, utilising all the speakers and totally immersing you in both the environment and the climbers' ordeal. Not only do all the channels get a thorough workout but so will your subwoofer, with plenty of bass extension to rattle your room. However in amongst all this chaos the dialogue remains clear, allowing you to remain engaged with the characters even as the film puts you as close to the summit of Everest as you'll probably ever want to be. Game of Thrones has been breaking records since it was first aired but with the steelbook re-release of the first season on Blu-ray it passed a new milestone by becoming the first TV series ever to be re-mixed in Dolby Atmos. As with the first season, the new Dolby Atmos soundtrack for the second is a revelation, elevating what was already a superb sound design to another level. The added overhead channels and the object-based design of the mix simply give every scene a greater sense of environment, it's as if the walls of the room just disappear and you are standing on the frozen wastes of the north or down in the bustling streets of King's Landing.

The addition of dragons is a sound designer's dream and they take full advantage of the added dimensionality of Dolby Atmos to breathe life into Deanerys's 'children'.
