Let‘s explore the pinnacle achievements transforming both the listening and viewing experience from audio-visual pioneers Dolby.
Dolby Atmos: The Third Dimension of Lifelike Sound
Object-based 3D sound takes movie atmosphere to new heights – literally! While surround sound already envelops listeners, Atmos adds speakers above and around the room. Sophisticated rendering precisely maps audio to 3D coordinates, enabling pinpoint accurate placement and motion overhead. Jets roar directly above; lightning cracks from rear to front; dialogue stays locked to characters onscreen. This mimics how sounds occur naturally better than ever, bringing a thrilling new dimension of immersion.
Atmos doesn‘t just add height channels; it creates audio "objects" with specific positional metadata relative to listener space. Elaborate algorithms encode this for various speaker layouts for life-like precision mapping cinema rigs up to 64 channels or home surround systems to 11 channels and beyond. This lets you fully experience sounds exactly where mixers place them in the scene rather than chasing channels. Discrete data feeds for floor and ceiling speakers maintain seamlessness as effects move around 16-foot bubbles of ambient audio in true 3D.
Engineers call this "adaptive" rather than "immersive" sound since it adapts objects metadata to any system instead of just immersing via fixed channels. This makes Atmos infinitely more scalable across everything from theaters to soundbars to headphones by rendering appropriate speaker/binaural outputs. The ability to properly manifest 3D audio perspectives with such variety remains unprecedented.
The Quest for Immersive Sound‘s Summit
Atmos launched commercially in 2012 with Pixar‘s animated film Brave. Back then under 300 US theaters supported Atmos, but its obvious breakthroughs ensuring lifelike sound movement through 3D space sparked swift adoption. Today over 6,000 global cinemas boast Atmos systems, while leading Hollywood studios uniformly mix using it.
On the home front, Dolby now counts hundreds of Atmos-enabled models across major AV receiver, speaker, soundbar and TV brands. Every Xbox and PlayStation console outputs Atmos too as do Roku devices and Apple TV 4K. Blu-ray films featured immersive tracks as early as 2014 with Atmos streaming following on Netflix & Amazon Prime by 2016.
The Experts‘ Verdict: Euphoria & Envelopment
From cinema to home theater enthusiasts, Atmos wows all exposed through unprecedented envelopment. "It develops a 3 dimensional sound bubble all around you…sound effects zip clearly over your head, dialogue stays focused on action below.
