Le Dernier Panache, Puy du Fou, France, May 2016

The L‑ISA multichannel platform is ideally suited to bringing immersive hyperreal sound into experiential venues and events such as theme parks, museums, houses of worship, clubs and marketing activations.

The L‑ISA Creative Ecosystem provides the sound designer with both the 3D-modeling and implementation resources to create a multidimensional audio landscape – and to manage it live. Our solutions deliver spatialized sound through L‑Acoustics’ industry-leading loudspeaker systems, proprietary processing hardware and software-based audio tools to wow audiences like never before.

Spatialized Creative Sound Design

A qualified L‑ISA Creative solution is the output of a comprehensive methodology that begins with an early collaboration between sound, visual and scenography experts. To ensure the best results, projects are modeled with our sound design software, pre-mixed in studio on our object-based platform and finally performed over the most suitable L‑Acoustics professional speakers.

L‑ISA Creative solutions can be adapted to venues of any size and provide the mixing engineer with the ability to place and move sound objects in 3-dimensional space while immersing the audience in an extraordinary experience.

L‑ISA Creative Sound Design Principles

Unlike L‑ISA Live designs, L‑ISA Creative solutions combine audio and visuals without reference to an onstage performing zone. They use a combination of 2- and 3-dimensional sound designs and incorporate frontal, fill, surround and overhead systems to achieve the specific design vision for the production.

Given that all L‑ISA Creative events are unique, the principal sound design challenge is to translate the vision of the creators into pertinent audio parameters which then form the basis for a qualified solution.

Creative Design Qualification

In order to assess the capabilities of a sound design to meet the standards required of an L‑ISA Creative solution, features have been added to L‑Acoustics Soundvision to assess designs against a protocol that evaluates and scores their acoustic performance as well as the qualitative elements that impact the audience’s perception of the audio.

Eight different parameters, which can be continuously adjusted and optimized in response to the project’s design requirements, contribute to the score of the sound design project, including:

  • Coverage performance, graded according to SPL Max, SPL Distribution and Time
  • Hyperrealism, scored according to Spatial Resolution and Horizontal and Vertical Localization
  • Immersion, graded for Panorama and Envelopment

The Benefits

Multidimensional Creative Mixing

Better than any other multichannel platform, L‑ISA provides an extraordinarily intuitive 3D-mixing environment that makes the process of multidimensional mixing as straightforward as possible, supporting the production of immersive content and unleashing imagination and creativity while still retaining extremely high reliability and sound quality.

The properties of each sound object are defined independently from the loudspeaker layout – so the entire mix can be faithfully scaled from the studio to a wide variety of venue and system configurations.

An object-based mix provides:

  • Precision, clarity and detail for every sound
  • The ability to adjust the perceived width and depth of any sound object
  • Separation in the system for concurrent sources without heavy equalization and compression
  • The ability to assign and transport each sound object to any location

Object-based Creative Mixing

The L‑ISA Creative Ecosystem interfaces seamlessly with Digital Audio Workstations and provides simple controls to manipulate every sound object in a 3-dimensional space. Parameters are stored in synchronization with audio tracks and can be recalled as snapshots, triggered through time code, modified from sensor inputs, etc.

The L‑ISA Processor provides five parameters to the mixing engineer for each sound object:


controls horizontal location


controls breadth


controls proximity


controls vertical location

Acoustic Enhancement: Virtual Acoustics for Added Creativity

Virtual Acoustics for All Scales

The proprietary L‑ISA room engine has been developed specifically for object-based audio and variable spatial configurations with an innovative approach to in-line convolution processing.

Automatic direct sound precedence control (patent pending) ensures localization across the entire audience for all scales without the need for fixed delays in the speaker system. Now engineers can create amazing acoustic spaces for all object positions – left, right, front, back, below or above!

Creative Controls Without the Complexity

Sound designers need tremendous flexibility to design unique spaces. The L‑ISA room engine provides advanced reverberation controls to create virtual acoustic spaces from small rooms to cathedrals. And no matter the audio objects in the space, patent-pending precedence control ensures proper localization for the entire audience regardless of venue size.

Innovative Features

With this revolutionary engine architecture comes a set of controls that has never been seen before. Gain Shaping controls how acoustic enhancement behaves in space according to the location and direction of the direct sound. Delay Shaping controls the propagation of the late components of the acoustic field to create a more natural sounding diffuse field. And distance simulation can be controlled with level attenuation and dry/wet ratios. All of these controls can be stored in presets for real-time recall during a performance.

Fully Adjustable




Precedence Safeguard

The L‑ISA Creative Ecosystem

The comprehensive L‑ISA Creative Ecosystem offers designers and engineers predictability, consistency and a sound design process that is easy to manage and simple to replicate, and which makes switching from traditional mono / stereo / LCR configurations to an L‑ISA design as straightforward as possible.

L‑ISA Source Control Plugin

The L‑ISA Source Control Plugin is designed for the live playback of object-based sequences created in DAWs. It allows for the storage and recall of object properties in the timeline, in synchronization with playback. The Plugin allows for spatialized studio post-mixing by recording a show and storing the object properties. It also ensures audio synchronization with other application components such as video, machinery, etc.

L‑ISA Processor

For extreme reliability, the L‑ISA Processor focuses solely on spatial audio processing, offering panning and room simulation for up to 96 audio objects based on defined speaker positioning information and mixing parameters (pan, width, distance, elevation, aux send) and creating up to 32 outputs.

L‑ISA Controller

The L‑ISA Controller offers, on a single screen, a visualization of all sound objects in the 3D mixing space for live monitoring and user interaction in Windows and Mac OS environments and transmits control information to the Processor for selected parameters (pan, width, distance, elevation, aux send) for each sound object.


Soundvision is L‑Acoustics’ proprietary acoustical and mechanical simulation program and is first 3D program capable of operating in real time. It calculates SPL coverage, SPL mapping and delay coverage (or mapping) for complex sound system and venue configurations. It now features advanced parameters to qualify and certify multichannel sound designs.

LA Network Manager 2

Supporting Windows and Mac OS X operating systems, the LA Network Manager 2 remote control software provides control and monitoring of up to 253 L‑Acoustics amplified controllers within the L‑Acoustics L‑NET Ethernet network.

“We wanted to offer something unique in the world with Le Dernier Panace. “The L‑ISA sound system gives the show not just originality, but more importantly, an exceptional and memorable experience to our visitors.”

— Nicolas de Villiers, president at Puy du Fou

Project Description

Le dernier Panache is the most daring show ever created at Puy du Fou – Theme Park – and it is only enhanced by the setting. The show was an immediate success, garnering the industry-recognized Thea Award for Outstanding achievement this year.

Sound Design Solution

L‑Acoustics and the Puy du Fou designed and installed an L‑ISA multi-channel immersive system that plunges spectators into the heart of the story, with realistic sound coming from the moving sources and not just from either side of the stage.

  • 24 clusters of two ARCS Focus and one ARCS Wide line source elements are arranged in a circle at angles of 15 degrees each
  • 8 Clusters of two SB18 for the low-frequency extension
  • 4 SB28 underneath the tribune for sub-frequency effects
  • A Front-fill of 13 x 5XT to cover the first rows of the audience

L-Acoustics has been working with Le Puy du Fou since 2000 when the first L‑Acoustics sound system was installed for the Gallo-roman stadium. Today, the manufacturer’s systems are featured throughout the park. When Le Puy du Fou shared the idea for Le Dernier Panache with their longtime partner, the answer was simple: we have a solution that is as ambitious as your idea: L‑ISA.

“It is fitting that Le Puy du Fou features the first permanent installment of our new L-ISA hyperrealistic sound solution,” said Christian Heil, chief executive officer at L‑Acoustics. “The long relationship between our companies allowed us to propose an ambitious – some people would say crazy – and the best thing is that Le Puy du Fou had the confidence and daring to say yes!”
