An AV receiver and surround sound speaker setup.A speaker system with upfiring drivers and Dolby Atmos processing, such as:.There is a chain of elements you need to have in place before you can properly experience Dolby Atmos, and the good news is that probably already have the makings of a system. What do you need to experience Dolby Atmos? However, it is a bit more flexible in that it doesn’t require overhead speakers for it to work. Like Dolby Atmos, DTS:X uses object-based sound to calculate which speaker needs to get what amount of sound to accurately convey the location of an object in space and create the most realistic experience possible. In a 5.1 setup, this is limited to just two zones – left and right – making it very difficult to pinpoint sounds in a scene. In contrast, conventional surround sound is channel-based, whereby sound effects are confined to a general zone. This means that specific objects within a scene, whether it be the clink of silverware in a quiet restaurant scene or a bullet whizzing by in your favourite action flick, can be represented by any speaker in the room at any given time, independently or together.įor example, if a helicopter flies overhead and to the right, the sound will start in the back of the room, move overhead, and disappear off to the right side. With a Dolby Atmos mix, individual on-screen elements are assigned their own audio track that can be positioned in a three-dimensional listening space, taking it beyond the bounds of traditional 5.1 or 7.1 surround sound channels. However, it’s not just the addition of height channels that makes Dolby Atmos so darn immersive over regular surround sound. Dolby Atmos creates overhead effects to give the sensation of being inside a dome of sound. We would express this as 5.1.2 and 5.1.4 or 7.1.2 and 7.1.4 with the end number denoting the number of height speakers installed. In a home theatre speaker system setup, this would mean adding either two or four speakers to the ceiling to an existing 5.1 or 7.1 setup. The addition of height information means that a sound like rain., for example, will actually sound like it’s coming from above you, and flying objects from overhead will actually sound like they’re moving around the room. Dolby Atmos is an object-based surround sound technology that expands beyond the single horizontal plane of conventional surround sound systems with the inclusion of ‘height’ channels. In many ways, Dolby Atmos is what surround sound always should’ve been. Making its way from commercial movie theatres to our living rooms, Dolby Atmos provides the biggest leap in cinema audio since surround sound. But what makes it so immersive, why should you care and what do you need to experience it at home? What is Dolby Atmos?
