But hidden among the grooves of the fluted pillars lurked an array of invisible loudspeakers, all connected to a bespoke sound system installed by French audio firm L-Acoustics. \u201cAnd some of the speakers that you can\u2019t see in Notre-Dame are the same ones that you can\u2019t see in this room,\u201d says L-Acoustics\u2019 Mary Beth Henson.\u00a0We\u2019re standing in a showroom at the firm\u2019s north-London HQ, and the absence of audio equipment is, as Henson notes, conspicuous. L-Acoustics calls the room a Hyriss \u2013 a Hyperreal Immersive Sound Space: its purpose is to provide the ultimate experience of sound. Behind the bespoke green cloth-covered panelling on the wall sit multiple sets of speakers spaced about a metre and a half apart, with an additional grid of 12 discreetly embedded in the ceiling.Even without music playing, the room itself sounds extraordinary \u2013 sweetly reverberant. This is a space whose every sonic characteristic can be controlled; if you want it to sound like a cathedral, or a bathroom, or a small concert hall, you can. If you want it to function as a cinema room with 5.1 or 7.1 surround sound, a karaoke booth, a sub-bass heavy nightclub or just an acoustically resonant space to sit and play piano in, that can happen with the tap of a button. And this isn\u2019t just a proof of concept; any room larger than 45sq m can be transformed into a Hyriss by L-Acoustics, in consultation with an architect or interior designer (from about \u20ac3,550 per square metre).Christian played some music and said, \u2018I think I\u2019ve just created the world\u2019s best hi-fi system\u2019All the technology behind it, from the engineering of the speakers to the algorithms spreading the sound throughout the room, was forged in the world of live music. As a young man, L-Acoustics\u2019 founder, Christian Heil, was inspired to shift from his background in particle physics into professional audio after attending a Pink Floyd show where the band was experimenting with quadrophonic sound, an early manifestation of spatial audio. By 1992, he and his firm had produced the first line array, a vertically mounted, gently curved arrangement of speakers which is now a familiar sight at arena and festival shows, but back then was revolutionary. In 2016, the firm created L-ISA (pronounced \u201cEliza\u201d), an immersive audio tool that allows artists to create spatial soundscapes.\u00a0\u201cYou\u2019re standing in the room where L-ISA was developed and demonstrated,\u201d says L-Acoustics\u2019 director of home and yacht, Nick Fichte. \u201cChristian played back some music and said, \u2018You know, I think I\u2019ve just created the world\u2019s best hi-fi system\u2019.\u201d While the Hyriss\u2019s extraordinary sound is no surprise, its flexibility is. A Dolby Atmos stream from Tidal is all-enveloping. Chest-thumping bass is a testament to the power of the sound system, but it can also render a John Williams orchestral piece (created using L-ISA) from the conductor\u2019s perspective, with French horns, cellos and glockenspiel all distinct and spatially separated.\u00a0Even music in bog-standard stereo can, with L-Acoustics technology, be spread out across the room, with AI detecting guitars, drums and vocals in real time and giving them their own space. I was briefly indulged and allowed to listen to some music that I\u2019d had a hand in making; hi-fi buffs often make bold claims that certain speakers allow you to hear very specific elements of recorded music with a new clarity, but this was the real deal.Investing in a surround-sound setup is traditionally a gruelling business: buying the elements of a 5.1 or 7.1 system, positioning them in a room, perpetually wondering whether they\u2019re in quite the right place and tweaking the setup accordingly. And all that effort in the service of just one position in the room, the so-called \u201csweet spot\u201d, where everything sounds just right. \u201cHyriss partly came out of Christian\u2019s inability to decide where speakers ought to be placed in a large room in his own house in the south of France,\u201d says Fichte. \u201cHe had a brainwave where he thought, well, if I put speakers everywhere, I can use the room however I like.\u201d There is no single point where Hyriss sounds best. The clarity, the volume, the sense of acoustic space, is evenly and beautifully spread. The sweet spot is everywhere.<\/p>\n","protected":false},"excerpt":{"rendered":"
