Some of us still remember the days of multichannel music created for Super Audio CD (SACD) or DVD Audio and the fact that even with very specific works designed to be recorded in multiple channels, the final effect could be laughable, not realistic, and sometimes not pleasant at all. But music mixed for Dolby Atmos is a completely different story. Recently, Dolby also developed Dolby Atmos implementations for headphones and smartphones, where an audio processing algorithm is used to convert the Atmos object metadata into a binaural 360° output, or what can also be described as a "virtual immersive experience." The experience is clearly superior to standard stereo reproduction, at least with movie and games soundtracks. Creating a similar experience on a large size soundbar is possible using clever audio processing, but was never achieved from a compact omnidirectional speaker array.Ī promotional representation of a Dolby Atmos soundbar from Sony. And that should be, at minimum, a traditional 7.1 multichannel layout with at least four speakers overhead.

But as home theater enthusiasts have already learned, in order to get a similar experience at home, they need additional speakers to fully be able to reproduce this immersive stage - most importantly, installing ceiling speakers, or at least have speakers with upward-firing drivers.Īt the same time, the audio industry has been experimenting how to generate a similar experience just with soundbars - and apart from the Sennheiser AMBEO soundbar, currently available - many other products available in the market show obvious limitations, not being even close to the impact of having multiple speakers and subwoofers in the room.Īfter all, Dolby Atmos content is generated from at least 128 audio tracks plus associated spatial audio description metadata or object-based audio, which translates the dynamic rendering to the loudspeakers available in the room. To the added dynamic of a larger immersive sound stage, Dolby Atmos adds the impact of height layers to the previous surround multichannel experience. Anyone who has recently watched a movie blockbuster in a modern cinema has certainly experienced and recognized the added emotional impact of a Dolby Atmos soundtrack.
