Release Notes

New Features

New SPAT Send Plugin with UI

Welcome a complete user interface to the SPAT integration plugin, SPAT Send. This new plugin version features the SPAT Source object parameters on a beautifully crafted interface that can be focused on the basic positional parameters or expanded to include advanced parameters. The UI size is now customizable like all other FLUX plugins and the Configuration for LAP (Local Audio Path) and OSC is streamlined together with RX (Receive) and TX (Transmit) data indication. 

New deep snapshot recall scope and safe matrix.

While previous version of SPAT Revolution allowed a user to scope the parameter category (source, room and masters) for each snapshot recall, this new deep snapshot advancement allows the user for a deeper scope of recall with a deeper level of parameter granularity that can be applied global or per snapshot. The new global recall safe can allow the same level of granularity, but specific to specific parameters to never be recalled.

Sum/Delay/Gain/Polarity in Master and Transcoder Matrix

Beyond a fresh look for any matrix in SPAT Revolution, the Master and Transcoder block module now allows for a complete summing, delay, gain and polarity control on the input to output routing making it the most practical tool for summing channels together, or routing a spatial “speaker pan” position output to multiple physical loudspeaker outputs at different delay and gain values. 

Additional New Features

• 3D View preference restructure
  3D view is the main environment window, looking at the source object soundscape. The view preference options have drastically increased over the development of SPAT Revolution. This major improvement restructure Source, Speaker, Nebula visualization and other generic view preferences in 4 distinctive panels.
  
  
• Advanced parameters for metering, with peak hold and meters control, as well as improved UI for high channel count
  
  
• New UI for input/output matrix
  
  
• Import of snapshots from other sessions 
  
  
• New option to copy the reverb parameter from one room to another with right click 

Improvements

• Add KNN parameters – Exponential for distance and max distance
  
  
• Snapshot page – Revamp of some controls on version history and inspector panel 
  
  
• SPAT Send – Enable OSC automation with LAP
  
  
• Source – Source radius is no longer supported 
  

In addition to this the 25.12 update provides maintenance and bug fix updates, more information available in the Release Notes.

As one of Lisbon’s most respected cultural institutions, Culturgest sought to expand the creative potential of its flagship Emílio Rui Vilar Auditorium, a 612-seat performance space known for its detailed wood architecture and refined acoustics. The venue, located in the Caixa Geral de Depósitos headquarters, already featured a high-quality cinema surround speaker system, but its engineering team aimed to evolve that infrastructure into a flexible, immersive audio environment capable of supporting live concerts, theatrical productions and experimental performances.

In collaboration with Audium and FLUX::, Culturgest became the first venue in Portugal to implement a fully immersive live sound system using FLUX:: SPAT Revolution. The system integrates a SPAT Revolution engine running up to 64 channels from the mixing console, routed via Dante and AES67 to the house speaker systems. Thirty-six surround speakers from the existing setup were reconfigured to handle rear, top and side channels, while the LR system used for traditional events was integrated into the immersive configuration. The entire setup was tonally matched to ensure transparent performance and cohesion between operation modes.

FLUX:: engineers worked closely with Audium and Culturgest’s in-house team to commission the system and provide extensive onsite training. The configuration supports multiple modes for live productions, including up to 32 active audio objects or reverberation-only simulations for acoustic performances. “Culturgest asked for an immersive system, and after a thorough analysis of the available options, FLUX:: SPAT Revolution was the main choice for this demanding venue,” said Tiago Laires of Audium. “In the end, and although we had a high level of expectation for SPAT, both Culturgest and I were blown away by the impressive result.”

The integration of SPAT Revolution has transformed Culturgest’s live production capabilities, allowing artists and engineers to explore new spatial soundscapes and audience experiences. “The expectations were high, but I can say that, after almost a year using SPAT Revolution, the expectations were largely exceeded,” said Ricardo Guerreiro, Culturgest’s In-House Sound Engineer.

Since installation, Culturgest has hosted a range of performances using the immersive setup—from orchestral concerts to experimental electroacoustic works. Artist and Composer Suse Ribeiro credited SPAT Revolution with unlocking new artistic freedom, noting that it allowed her to move beyond her initial design concepts to achieve exceptional technical and creative results.

Through precise integration, advanced networking and deep collaboration between FLUX:: and Audium, Culturgest has emerged as a leader in immersive live audio in Portugal, setting a new standard for how technology and artistry converge in contemporary performance venues.

HO CHI MINH CITY, VIETNAM — HARMAN Professional Solutions, in collaboration with AV integration partner Ba Sao Audio, recently deployed one of the region’s first large-scale spatial audio deployments for live theater. The production CHÀO celebrates Vietnamese heritage through traditional music, narrative design and immersive technologies, all powered by a fully integrated HARMAN Professional Solutions system across the brand portfolio, including JBL Professional, FLUX::, BSS, and others.

Conceived by Nguyễn Khắc Anh, CEO of Ba Sao Investment, with technical direction by Vũ Hữu Thắng, CHÀO reimagines Vietnamese heritage through a compelling fusion of traditional music, dynamic visuals, and immersive sound design. The performance features an original orchestral suite with 30 traditional Vietnamese instruments, supported by a massive 150-square-meter LED screen and synchronized lighting.

From a technical standpoint, CHÀO posed a unique challenge. The performers and the audience occupy a shared acoustic environment, with no stage monitors or in-ear systems. This required precise spatial mixing and system tuning to maintain instrument fidelity while avoiding feedback. Ba Sao Audio deployed a 20.4-channel immersive sound system to deliver a fully three-dimensional sound experience, anchored by FLUX:: SPAT Revolution to provide precise spatial positioning and real-time control of sound sources throughout the venue.

“This collaboration has enabled us to create a powerful and engaging experience for audiences,” said Vũ Hữu Thắng, Technical Director, Ba Sao Audio. “Working with HARMAN’s integrated solutions allowed us to meet the technical demands of the production while supporting its creative goals.”

The immersive system was supported by 20 JBL AC18/95 loudspeakers for full-range coverage and four JBL STX818S subwoofers for powerful, well-controlled low-frequency response. Crown CDi Drivecore 4|600 and MA9000i amplifiers handled power and system control while 49 AKG microphones, including the C214, C519M, C411PP and C451B models, were chosen for their ability to capture the detail and texture of traditional Vietnamese instruments. Mixing and routing were managed using a Soundcraft Vi2000 digital mixing console paired with a 64-channel Dante stagebox. System processing and spatial audio rendering were handled by BSS Soundweb BLU-806 and BLU-BOB2 processors together with the SPAT Revolution real-time Immersive audio engine.

“This project exemplifies how our end-to-end solutions can elevate cultural storytelling,” said Amar Subash, VP & GM, Professional Solutions, APAC, “CHÀO is a model for how immersive technologies can preserve and amplify tradition in a way that’s both modern and moving.”

The result was a seamless fusion of tradition and innovation, setting a new benchmark for immersive cultural performance through integrated AV systems. Audiences were fully enveloped in sound and story, experiencing Vietnamese culture in a way that was both emotionally resonant and technologically groundbreaking.

Absolute vs. Relative OSC messages

Traditionally, OSC messages require users to specify the desired value for a parameter. This approach is ideal for scenarios like setting precise trajectory values. For example, to set a parameter to a specific value, we historically used an Absolute OSC message:

/room/1/gain/ -10

In contrast, Relative OSC messages allow users to define an offset rather than a specific value. This means you can adjust parameters incrementally, such as increasing room gain by +3dB or decreasing source distance by -2m. This flexibility is amplified when you don’t have bidirectional integration, as the parameter current value is unknown, and can simplify the interaction with SPAT Revolution.

How Relative OSC messages work

Relative OSC messages follow the same structure as standard OSC messages, with the addition of a path keyword. For instance, to offset the room gain by +3db, you would use:

/room/1/relative/gain 3

This consistency ensures that the OSC path structure remains unchanged, allowing users to utilize wildcards to target multiple objects or add interpolation timing. For example, to offset the distance of all sources by 2 meters over 5 seconds, you would use:

/source/*/relative/dist 2.0 5.0

Getting started with Relative OSC messages

To assist you in leveraging this new feature, we provide a QLab5 template with examples of Relative OSC messages. This resource will guide you through your initial steps and help you explore the full potential of Relative OSC.

You can find all available controls in the updated OSC table, which includes all available OSC commands in SPAT Revolution.
