revolutionise the immersive audio experience, with
'next-generation' audio technology delivering crystal-clear, concert-grade sound to each seat in Sphere through3D Audio-Beamforming and
Wave Field Synthesis

Sphere Entertainment Co has unveiled Sphere Immersive Sound, powered by HOLOPLOT, the world’s most advanced audio system, which provides “crystal-clear”, individualised sound to every seat in Sphere, a next generation entertainment medium opening in Las Vegas this autumn. Sphere Studios, which develops groundbreaking technologies and content, partnered with HOLOPLOT, a global leader in 3D audio technology, to create Sphere Immersive Sound – the world’s largest, fully integrated concert-grade audio system that is said to revolutionise immersive audio experiences.

“Sphere Immersive Sound is a cornerstone of the custom-designed technology that will make Sphere unlike any venue, anywhere in the world, providing audio with unmatched clarity and precision to every guest, no matter where they are seated,” said David Dibble, CEO, MSG Ventures, a division of Sphere Entertainment. “Creating this experience required us to go far beyond existing audio technology, and in HOLOPLOT we found a partner at the forefront of innovation to help achieve our vision and truly transform what is possible with audio.”

Roman Sick, CEO, HOLOPLOT, added: “From the beginning, HOLOPLOT has been focused on radically transforming audio technology, rethinking the underlying physics of sound reproduction as we know it. Working alongside Sphere Studios on Sphere Immersive Sound has been a truly thrilling opportunity for our team – challenging us to extend the boundaries of our technology at an unparalleled scale and create a revolutionary listening experience.”

Sphere Immersive Sound is the world’s largest concert-grade audio system and was specifically developed for Sphere’s unique curved interior. The system consists of approximately 1,600 permanently installed and 300 mobile HOLOPLOT X1 Matrix Array loudspeaker modules and includes a total of 167,000 individually amplified loudspeaker drivers. The system utilises HOLOPLOT’s next-generation 3D Audio-Beamforming and Wave Field Synthesis technology to transform how audio is delivered in large-scale venues. This results in controlled, consistent, and crystal-clear concert-grade audio for audiences of up to 20,000 people, providing each audience member with a truly exceptional and personalised listening experience. The entire sound system is completely hidden behind Sphere’s 160,000 square foot interior LED display plane. Any audio transmission losses are fully compensated for by HOLOPLOT’s algorithms in the optimisation engine, resulting in clear, full-range sound with virtually no coloration and a completely unobstructed visual LED surface – which wraps up, over and around the audience and combines with Sphere Immersive Sound to create a fully immersive environment.

Traditional loudspeaker technology in large-scale venues can result in audio quality that diminishes as distance from the speakers increases, due to the uncontrolled nature of sound wave propagation. HOLOPLOT’s patented 3D Audio-Beamforming technology uses intelligent software algorithms to create unique, highly controlled, and more efficient soundwaves than conventional speakers, ensuring that levels and quality remain consistent from point of origin to destination – even over large distances. HOLOPLOT’s propriety beamforming technology can also simultaneously send unique audio content to specific locations in the venue, creating the possibility for different sections to hear completely different content – such as languages, music, or sound effects – offering limitless opportunities for truly customised and immersive audio experiences.

Sphere Immersive Sound will additionally utilise HOLOPLOT’s unique Wave Field Synthesis capabilities, a spatial audio rendering technique that leverages virtual acoustic environments. With conventional audio technology, the perceived origin of a sound has traditionally been the location of the loudspeaker. Using Wave Field Synthesis, sound designers can create a virtual point of origin, which can then be placed in a precise spatial location. This enables audio to be directed to the listener so that it sounds close, even though the source is far away – for example, an audience member could hear a whisper that sounds like someone is talking directly in their ear.

Sphere will open its doors on September 29 with the first of U2’s 25 performances of “U2:UV Achtung Baby Live At Sphere,” and the Darren Aronofsky-directed Sphere Experience, Postcard from Earth, will debut on October 6. Tickets are currently on sale at

U2’s The Edge concluded: “The beauty of Sphere is not only the ground-breaking technology that will make it so unique, with the world’s most advanced audio system integrated into a structure which is designed with sound quality as a priority; it’s also the possibilities around immersive experiences in real and imaginary landscapes. In short, it’s a canvas of an unparalleled scale and image resolution, and a once-in-a-generation opportunity. We all thought about it and decided we’d be mad not to accept the invitation.”
