Hi all !

Hope you’re doing well, and nice to meet those I don’t know ! I wanted to start this groups with some discussion ?

Don’t know the starting point of this discussion ?

With Terence Briand, Gael Martinet from Flux and 360Prod we start to write something as generic speaker implantation, to separate different types of immersive set-up, how separate technic and artistic around spatial audio, etc.

Can we start discussion with our last linkedin post ?

We’re continuing the conversation: our illustrations of immersion

A proposal from 360Prod

The term immersive is everywhere, yet it doesn’t always describe the same reality.

Terence’s article, followed by Gaël’s, reminded us of something obvious: we need a clear and practical vocabulary — usable by artists, venues, and technicians alike.

We support the 5 proposed labels:

Frontal Localized · Extended · 360° · Dome · 360° Central

A simple, concrete foundation that already clarifies many situations.

Our contribution:

• visual illustrations to make these labels immediately understandable,

• and a few recommendations drawn from our artistic needs and real-world experience.

Because in our 360° creations, what matters most is not the number of loudspeakers or the algorithm:

it’s listening coherence.

7 proposed recommendations:

Valid for all configurations: frontal, extended, 360°, dome, or central.

1️⃣ Every loudspeaker must cover the entire audience

No dead zones, no overly dominant spots.

2️⃣ Loudspeakers must overlap

The audience should never be “between” two beams.

3️⃣ Distances and levels must be balanced

We aim for a single sound field, not a mosaic.

4️⃣ The spectrum must remain consistent everywhere

Same timbre = natural immersion.

5️⃣ The system grid must be dense enough

A regular network = a stable soundstage.

6️⃣ Loudspeakers must be properly positioned (height/distance)

Too close = fragmentation.

Too high = disconnection.

7️⃣ Ultimately: perceived uniformity

If 80% of the audience is within ±3 dB and the timbre is stable, the system is coherent.

These are not constraints:

They are the minimum conditions for a spatial creation to truly exist.

Why are we responding today?

Because we’re preparing today’s JTSE round table (1:45–3:15 PM) with Terence Briand, and we want to contribute to this movement with a clear, visual, and immediately useful tool.

A shared language means enabling:

• artists to understand what a venue truly allows,

• venues to highlight their installations,

• audiences to experience coherent immersion.

Looking forward to hearing how the discussion continues!

😊
