Portable Dolby Atmos Studios Could Change How Immersive Rooms Are Built

A new 9.1.4 studio in Austin suggests immersive mixing rooms may not need to be permanent to be predictable.

Immersive audio usually brings to mind a purpose-built room, lots of loudspeakers and a fairly permanent commitment to the building. A new studio in Austin is taking a different approach.

Waterloo Sound has opened a portable 9.1.4 Dolby Atmos studio built around the modular Nu•Studio system, using JBL Professional 708 monitors and Crown amplification. According to ProSoundWeb, the structure is designed to provide a repeatable acoustic environment while hiding much of the technology behind acoustically transparent surfaces.

The interesting part is not simply that it is portable

Portable studios are not new. What makes this project more interesting is the attempt to standardise the room itself.

The Nu•Studio concept uses consistent dimensions, materials and acoustic specifications so that one installation should behave much like another. That is a very different idea from a conventional control room, where every new space comes with its own dimensions, construction, modal behaviour and treatment problems.

Why 9.1.4 raises the acoustic stakes

A 9.1.4 Atmos room surrounds the listener with loudspeakers at ear level and overhead. In Waterloo Sound's setup, the same JBL 708 monitor is used throughout the system.

That consistency is useful because audio objects can move from the front of the room to the sides, rear or overhead. If the loudspeakers or the acoustic conditions change too dramatically from one direction to another, the movement becomes less convincing and the tonal balance can shift as the object travels.

The room therefore has to do more than sound generally pleasant. Reflections, decay, low-frequency behaviour and channel-to-channel consistency all become part of whether the immersive image feels stable.

A modular room is an acoustic idea as much as a construction idea

From an acoustic point of view, one of the biggest advantages of a modular system is predictability.

If a room is repeatedly built to the same dimensions and material specification, the main reflection paths and modal structure become much easier to anticipate. Treatment can then be designed as part of the system rather than added afterwards as a response to whatever the shell happens to do.

That does not remove the need for calibration or measurement, but it potentially reduces the number of surprises.

It is a useful reminder that acoustic treatment works best when it is considered as part of the room design, not simply as decoration applied once the loudspeakers are already in place.

Could this filter down into smaller studios?

Most home studios are not about to install fourteen loudspeakers inside a modular room. But the underlying idea is relevant well beyond Atmos.

Small studios are often built around awkward spare bedrooms, converted garages and rented spaces. That means treatment has to work around doors, windows, furniture and the possibility that the whole setup may need to move later.

Portable bass trapping, freestanding absorbers, ceiling treatment that can be removed, and consistent panel layouts already point in the same direction: creating a monitoring environment that is less dependent on the building itself.

The more modular studio design becomes, the more valuable predictable acoustic treatment becomes alongside it.

What this says about where studios are heading

The wider trend seems to be towards flexibility. Studios are becoming smaller, more hybrid and more likely to serve several purposes at once. Immersive formats add complexity, but projects such as Waterloo Sound suggest the room itself can become more adaptable too.

That does not make acoustics less important. If anything, it pushes room design closer to the centre of the system.

A studio that can be moved is useful. A studio that can be moved and still behaves predictably is much more interesting.
