Interview with Julien Laval on Ambiance, L-ISA, and the Future of Acoustic Design

1

The use of immersive audio in modern productions, installations, and performance venues is growing rapidly, driving a new focus on adaptable acoustic environments. At the forefront of this evolution is Ambiance, the virtual acoustics system from L-Acoustics, powered by L-ISA.

Ambiance combines high-resolution L-Acoustics loudspeakers, strategically placed reference microphones, and the L-ISA Processor II running a real-time 3D Room Engine.

This integrated system enables venue operators and sound designers to dynamically shape a room’s acoustics — from the clarity required for spoken word to the enveloping reverberation of a full-scale concert — without altering a single element of the physical architecture.

At Audio Visual Days in Riga, we had the pleasure of speaking with Julien Laval, Application Project Engineer at L-Acoustics, shortly after his live demonstration of the Ambiance Virtual Acoustics System.

A key highlight of the Riga installation was the ceiling design, which showcased how Ambiance can be seamlessly integrated into virtually any space. The ceiling-mounted microphones and loudspeakers perfectly illustrated that immersive acoustics are no longer limited by room geometry — Ambiance brings flexibility and precision to every environment.

In our conversation, Julien explained how spatial audio is redefining the relationship between architecture and sound — and why the future of acoustics begins much earlier in the design process than most people realize.

Why is Ambiance such a game-changer for architectural spaces?

It’s not just a sound system — Ambiance is a tool for shaping the acoustic identity of a space. With a network of microphones and loudspeakers, it creates a dynamic acoustic environment that can adapt in real time. For venues like theaters, concert halls, or even museums, that means no more compromise between visual design and optimal acoustics.

What do architects need to understand about spatial audio today?

That sound is architecture. It’s not just about aesthetics or form, it’s also about how a space feels. With Ambiance, we can offer architects and engineers a way to co-design the soundscape alongside the building itself — using digital tools and L-ISA processing to switch between acoustic presets instantly.

How does Ambiance improve collaboration between disciplines?

Traditionally, acoustic treatments come late in the project. But with Ambiance and L-ISA, we can involve sound design early on. That helps venues become more flexible — you can move from a spoken word event to a classical concert without physical changes to the room.

What’s your key message to the professionals who joined us in Riga?

Don't separate sound from space. Technology now allows us to integrate them — and create more meaningful, emotional, and inclusive experiences in every venue.

Designed for architects, consultants, and creatives alike, Ambiance transforms the way acoustic design is approached, reconnecting space and sound in a programmable and artistic way.
