Orlando, FL—February 2020… Acclaimed audio engineer and sound designer Dan Scott has helped create Emmy award-winning television programs, as well as films, rides, and Broadway-caliber theater shows in venues around the world. A member of the Orlando-based Ty Fy Studios team since 2007, Scott has worked for such elite clients as LucasFilm, Cartoon Network, Fox, Walt Disney Entertainment, and Walt Disney Imagineering. Since 2016, he has relied on FLUX:: Immersive’s Spat Revolution real-time 3D audio mixing software to create realistic immersive virtual audio environments.
“The first show that I used Spat Revolution on was for a cruise line,” recalls Scott. “The ship had a new, large-scale theater show with a lot of immersive technologies. They were putting time and money into making the show look brilliant, with a ton of new video technology. They used small set pieces and a giant 6K-resolution curved LED video wall with shading and mapping that tracked the set, so the video reacted to what was happening onstage. There were projections on the floor and on the walls, and the scenes were dynamic and changing. They did a great job of changing the feel of the room for every scene. It was really beautiful.”
Scott wanted to scale up the show’s audio technology to complement the high-end video but the theater had a conventional audio infrastructure. ”With Spat I was able to use every individual speaker to create a virtual room instead of just panning between matrixed speaker clusters. I used Spat to spatialize dialog, effects, and music without any additional hardware.”
In theme park and cruise line productions, setting the mood is crucial to the experience, Scott observes. “From the moment they walk into the venue, you need to take the guests away from the thousands of people they’ve been surrounded by all day and transport them into the story you’re telling. The preshow walk-in for this specific show was an ambient soundscape to put the audience inside a craftsman’s workshop, including torches projected on the walls along the aisles, conveniently right on top of the speakers,” he describes. “Those were my favorite ambient elements of the scene. With Spat I was able to put different subtle crackling on every torch, and as you walked by each one you heard the torches’ sound go by. Spat gave us the ability to make it truly immersive and different for each person in the audience.”
During the walk-in, Scott was able to give audience members the effect of some elements coming from outside the walls of the workshop, in addition to the sounds coming from within, before the actor arrived onstage. “You hear him get up and walk, his chair scrapes, and it sounds as if he were backstage, even though we’re just using normal line array speakers up front,” Scott observes. “Spat Revolution placed everything so well that it sounded like he walked across the stage, wound a music box, and listened to a song play for a few moments; then he’d walk the other way and try one of his other music boxes. When the show started, we placed the sound right where the actor came up on a lift holding one of the music boxes we had just heard.”
Panning audio in a multi-speaker system is not new, Scott points out, “but Spat glues everything together so it doesn’t feel like you’re just panning from speaker to speaker. The virtual room adds reflections, and you’re localizing sources in the room by using every individual speaker to help create the environment, instead of just changing the volume percentage across the speakers.”
“I love that Spat automation is controlled by, and saved directly within, our Pro Tools sessions,” Scott continues. “We’ve used it in shows set outdoors in the countryside, dungeons, race tracks, you name it. It’s awesome to create what we want each space to sound like and grab automation snapshots to recall through the timeline of the show. Then anything we throw into that room feels like it’s in the right space for the scene. And it’s not just a sound coming from a speaker. You’re virtualizing the entire environment and utilizing every speaker in the system.”
Spat Revolution also enables the Ty Fy team to develop abnormal room layouts. “That’s big in theme parks,” Scott adds. “I worked on a Halloween attraction in Hong Kong where there were segments with multiple connected rooms, and I was able to easily move sounds realistically between them. The main sound source was placed in one room but you would hear the ambience in the next room over, so you get a sense of what’s coming. This was all set in a giant castle that was made of styrofoam and wire, so it didn’t have a natural acoustic ambience that matched the visual—but we could create an ambience that made the space feel much bigger than it actually was. It’s a lot more realistic with Spat than with previous methods, and it’s a lot more achievable because it’s faster and less expensive.”
Scott just finished a 360-degree film that was mixed in Dolby Atmos. “We were using the Dolby setup but I knew I could achieve some elements better in Spat because I could virtualize the entire space,” he notes. “Atmos is great and gives you access to a large number of speakers but it’s only discrete panning; it’s not filtering or adding ambience. It’s so great to be able take my sources into Spat, quickly design a room layout using either a CAD drawing or some quick laser measurements for accurate speaker locations, and source the outputs through the Atmos system. With Spat it was easier and faster to get more believable sounding movements.”
Scott has used Spat so successfully that clients specifically ask for it. “The reaction has been unanimously positive,” he reports. “Spat gives us more options and frees us. It opens up the creative process.”

Spat Revolution is a software engine running on standard computer hardware, dedicated to offline show content creation workflows and real time live applications.Computer Hardware
Running on generic hardware means that a vast pool of audio interfaces (e.g., MADI, network AVB, or Dante / AES67 virtual audio entities), and a wide range of sample rate options (from 44.1Khz – 384Khz), are available for the system device setup. Low latency can be achieved with low block size software options (starting at 16 block size), the appropriate choice of audio interface, and most importantly, a computer sufficiently resourced and optimized for real time audio. The actual Spat setup (number of sources, rooms and such) has no impact on latency, which is predictable, fixed, and can be easily defined in accordance with the user’s hardware setup.
Simultaneous output systems (virtual spaces called rooms) with more than 32 channels of networked 48Khz audio, or hardware dedicated as a real-time audio engine , typically requires specific validation.
In most application scenarios, a dedicated computer is preferred. While memory (RAM) resources are not critical, multiple core CPU processing power is critical, as parallel processing is used to treat the actual source in the software. Because the software offers 3D control areas, an efficient graphics with at least 4-8 Gb of memory is also required. Appropriate e optimization of the computer will then achieve optimal system performance.
For those not inclined to DYI system design, hardware can be specified (and provided) by integrators or via the FLUX::Immersive Consulting Group, offering a range of services for system deployment and integration. Channel count, sample rate, audio distribution method, and any required third party control integration , are basic parameters when defining proper system design elements.Live production, Immersive technical services, and consultancy
To support live production deployments, technical services are available from FLUX:: Immersive Consulting Group, ranging from fully configured hardware/software system packages based on specific project requirements, to pre-design, guidelines, deployments, system tuning, commissioning, and training.
To support Live production, new software options will be available in 2020 offering live application-specific feature sets:
With content creation workflow a critical part of the live production process, Spat Revolution’s ability to run on generic hardware offers the sound designer an opportunity to start an offline conception on a local computer (without the need for specific hardware). Spat Revolution seamlessly integrates with a variety of DAWs and Playback systems, allowing for local inter-application audio transport and automation. Compatible third party systems include Ableton Live, Nuendo, Pro Tools, Reaper, QLab, and many others. Spat Revolution’s production suite includes three plugins (AU, AAX and VST):Spat Send, Spat Return and Spat Room. The user can build automation network cues, write automation of an immersive mix to a timeline or to cues, preview the results (binaurally or on smaller scale speaker arrangement), and build a show that is ready to move to dedicated live playback systems and Spat Revolution Live Computer engine.
From creation to delivery!
The creation phase can be managed on a single computer, and easily migrated to a network of show controllers, audio playback, mixing desks and Immersive audio engines.Real Time Software Engine
Working in a live, real-time engine mode requires the ability for control via a variety of third party systems over the network. This integration is accomplished via the Spat OSC (Open Sound Control) dictionary, or via the presence of Spat plugins on the network from the DAW or Playback system. Live console integrates the ability to provide encoder control for each source in Spat Revolution, and take advantage of mixing desk snapshot capability to create automation with timing interpolation parameters. This integration is currently offered with Avid S6L Live Sound console via Spat Send plugin or using generic OSC commands with mixing console offering OSC control, such as the Digico SD series. The power of OSC means that any third party system with this capability can potentially be part of the immersive audio control. Also on the subject of real time, Spat Revolution offers support for real time tracking systems such as BlackTrax (RTTrPM procoll support), Zactrack and Stagetracker, which can be integrated in this real time immersive audio package.Redundancy
Redundancy and the need for a complete fail over being critical in live production, the Spat Revolution immersive system can operate in redundant mode, with the secondary system simultaneously outputting discrete audio channels as back-up output, routed to a loudspeaker management system or back to the audio mixing system. For this, two Spat Revolution systems (Spat license includes two activations) can be deployed and simultaneously receive audio feed and automation. While the Spat Send plugin allows for dual OSC output, each targeting the systems in parallel, other controllers (Lemur Ipad controllers, OSC Network cues, etc.) can target both systems as well . Audio is output from both the primary and secondary systems, providing redundant sources to the diffusion loudspeaker system.
To this extent, Spat Revolution can be deployed strictly as a remote control (no audio processing), targeting commands to two Spat computer engines dedicated to audio processing via OSC commands.Immersive Audio Spatialization Techniques
Spat Revolution addresses panning over multi-channel immersive audio systems without the requirement of a closed framework, adapting easily to speaker design arrangements for various productions with spatial audio techniques and panning methods to suit different applications (Binaural, High order ambisonic HOA or 2D/3D Channels based with WFS, VPAB, DBAP, KNN, SPCAP and more panning methods). Multiple virtual spaces in the software engine called “Rooms” allow you to deliver to multiple diffusion systems (virtual spaces using all or partial speaker arrangement setups) and offer extensive flexibility in creating custom 2D or 3D speaker arrangements. This allows addressing unconventional stage setups where 5, 7 or more speaker hangs are spread across the stage with somewhat equal separation between each, or having an arrangement of multiple loudspeakers in arbitrary locations. It is important to note that these virtual spaces each include acoustic simulations (reverb engines) to generate early reflections localized with each source, along with a reverb tail end that is diffused at the outputs, thus creating a sense of depth and reality!
On the subject of multiple virtual rooms in Spat revolution, it is important to mention that in the creation phase or studio style scenario, delivering simultaneous output streams is created by recording multiple stream formats of the same immersive mix in the DAW.. For example, a sound designer can create a binaural output preview on headphones while on a plane, and a surround speaker arrangement for studio work, while simultaneously creating content for multi-speaker arrangements of the actual show itself which may have speakers by the dozen!
Spat Revolution also offers advanced virtual source parameters from the simple (basic radiation control of azimuth, effective 360 degree pan, and basic source distance) to very complex situations where multiple perceptual factors are being controlledSoftware engineering and technology
FLUX:: has been a software development partner with French research institute IRCAM (www.ircam.fr), since 2008, and Spat Revolution is the result of decades of research and achievements. Many of these technologies have been successfully deployed in live sound installations with products including Spat in MaxMSP, Panoramix, with the legacy unique Spat audio plugin, and most recently with Spat Revolution.
The FLUX:: and IRCAM cooperation offers a variety of spatial audio techniques to users and designers, sharing a vision of open development. Behind these various spatialization and audio panning techniques is the desire to offer creativity, flexibility and the ability to adapt to each application and creative challenge, whether sweet spot-centric , live performance, or and installation-based, and regardless of where the audience may be distributed.

Saskatoon, Canada—December 2019… When indie-rock trio Close Talker launched its
new LP, How Do We Stay Here?, they didn’t want to introduce it with a typical live show.
The band wanted people to truly listen to the music, with no distractions, and they sought
a fresh approach that would set them apart. The multi-instrumentalist trio of Matt
Kopperud, Will Quiring, and Christopher Morien and front-of-house engineer Kellan
Thackeray considered a listening party, with the band playing live and the audience
wearing headphones. It was a good start but they wanted to deliver something
more—say, an immersive, 3D experience. But how?
While they were mulling the possibilities, Thackeray met LS Media’s Hugo Larin and
Benoit Favreau, who were offering demos of the AVID S6L live mixing console. The LS
Media team also showed FLUX:: Spat Revolution real-time 3D audio mixing
software—and Thackeray realized he might have found the solution for Close Talker’s
The result of a partnership between French software developer FLUX:: and the French
research institute IRCAM, Spat Revolution lets you assign incoming audio to a practically
unlimited number of source objects in a virtual space. Each source object has an
extensive set of parameters controlling all aspects of the source in the space, including
real-time changes in position and much more, enabling the creation of complex, real-
time, immersive audio experiences.
Spat Revolution source objects appear in a virtual room and can be assigned to multiple
virtual rooms with different acoustic simulations and multiple different output destinations.
The results can be delivered in several formats, including as a binaural mix. Spat
Revolution also can integrate, locally and over a network, with DAWs, control devices,
and real-time tracking systems.
After consulting with Larin, Thackeray and the band realized this meant they could
deliver the concert they dreamt of, in which audience members listened on headphones
to an immersive binaural mix of the band’s real-time performance. “An ‘immersive
binaural mix’ is a nerdy way of saying you’re in the middle of the band, and the
instruments are around you, as opposed to shooting at you,” translates Close Talker’s
Kopperud. “We learned that it really does add value and depth to the experience. What’s
unique about it is our ability to put instruments around your head and not just in fixed
positions, and we can move the instruments around your head live, in real time. What’s
impressive on the tech end is that we’re able to process 3D movements around the
subject in real time without latency. So it’s putting the audience in the center of the music
and allowing the music to really engulf them.”
What began as one listening party turned into Close Talker’s trans-Canada “Immersion”
tour. Each venue accommodates up to 64 audience members listening on Audio-
Technica PRO5X headphones, which are fed by four 16-channel headphone distribution
amps. Since delivery is on headphones, “Immersion” concerts can be held in venues that
normally would not accommodate a live show.
“The AVID S6L console is processing all of the inputs, and we have two MADI cards in
the S6L engine, so the direct outs are patched out to two MADI interfaces that are
connected to two Mac mini computers running Spat,” Thackeray reveals. “It’s a fully
redundant system: The minis are running in parallel, so if one fails, I can very easily
switch to my backup system, which is always following all of my snapshots. The
integration of the AVID with Spat Revolution is fantastic.”
In Spat Revolution, Thackeray and Close Talker spatialize the audio streams in two
virtual rooms, one binaural and one stereo. Instruments they want to move around and
play with are assigned to the binaural room. Kick drum, bass synth, and bass guitar are
usually in the stereo room to provide a more traditional impact, although they could be
processed in the binaural room for effect. Depending on placement and movement within
the virtual rooms, the software generates the appropriate early reflections, clusters and
tail from acoustic simulation, creating a sense of depth and reality. The
outputs of the two virtual rooms are then returned to the console, summed, and sent via
the left/right main bus to the headphone distribution system. An AVID Pro Tools system
handles the recording of every show and enables virtual soundchecks for refining the
“The artistic intent of making these shows a communal experience, and knowing I had
the technology to do this, got me hooked right away on the project,” Thackeray
declares. “Like anything new, the question was how it would integrate into the creation-
to-delivery workflow. The possibility was given to the band to start creating in their DAW
environment, experiment, and prepare some rough spatial mix concepts positioning and
setting properties of sources as objects in the virtual space. This was done as they were
monitoring in various formats or with different binaural HRTFs.”
The result is a unique and intimate concert experience that achieves everything the band
hoped for. “Immersion’ is us trying to create an experience for the audience that’s
different from anything they’ve experienced before,” Quiring observes. “This is the most
intimate setting we could create to showcase our album exactly as we intended,” agrees
Kopperud. “The philosophy of our new album and the philosophy of this project have
merged at the perfect time. The whole album is an effort to describe something
indescribable. It’s us wrestling of this idea of trying to define what makes something
special, special. It would have been easier to just have left this as an idea that we dreamt
up in the van, like, ‘some band should do this someday.’ It’s pretty cool to look back and
reflect that we’re that band.”

Close Talker, an Indie Rock band from Saskatchewan in Canada, virtually places their audience in the center of the stage with their silent binaural show Immersive.
The pre-production, live performance and recording of the show was created with the AVID S6L, Pro Tools and the Spat Revolution Immersive Audio Engine, using binaural audio and headphones for the audience.
An Avid S6L console with 2 stage remote I/O’s are handling the inputs and channel processing, while each input channel is sent post fader direct out to two computers (Main and Backup) running the Spat Revolution Immersive Audio Engine.
With Spat Revolution the mixing engineer creates the Spatial scene, the 3D location of the sources, Reverberation, Effects, and generate a binaural spatial audio mix which in the end is returned to the mixing desk and distributed to the audience’s headphones.
The S6L integrates the Spat Revolution using a plugin that allows for all the source parameters (each individual source / object going into the software) to be accessible on the encoders on the console and to be used in snapshots (show automation).
Kellan Thackeray, FOH for Close Talker, had a vision of where he wanted to bring this, and had been experimenting with some technologies to get there.
“Think silent disco but the audience headphone mix is processed with Spat Revolution to give the mix that extra push – this is a seated hardwired show to minimize latency and noise. The artistic intent of making these shows a communal experience, and knowing I had the technology and a way to do this, got me hooked right away on the project.”
The audience’s headphone mix is created with cutting edge binaural mixing technology, live in real time. The sound fully immerses the audience with instrumentation and voices orbiting and swirling around them on all axes, increasing the impact and depth of the band’s already acclaimed live show.
“Like anything new, the question was how it would Integrate in the creation to delivery workflow that became key. The possibility was given to the band to start the creation in their DAW environment, experiment and prepare some rough spatial mix concepts positioning and setting properties of source / objects in the space. This was done as they were monitoring in various formats or with different binaural HRTFs. “
As the time arrived for the actual pre-production and band rehearsal, the source / object parameters were captured with the snapshots of the S6L system as a starting point, then the programming of show snapshots was done. A Pro Tools system handles the recording of every show, and the ability to do a virtual production (virtual soundcheck) for refining the mixes.

Skylight – Notes from a Logbook: smarturl.it/d0hwty
Composer, Sound engineer, owner of St. Mary’s Space, recording studio and arts space in the magical West Highlands of Scotland.
My work happens at the intersection between experimentalism, improvisation and left-field rock and pop, which has allowed me to collaborate with many amazing artists, musicians, filmmakers, dancers and performers, including Akram Khan, Gavin Bryars, Kathryn Joseph and Misterlee.
For the last few years I have been working almost exclusively ambisonically, that is to say, recording, synthesizing and mainly authoring into a spherical soundfield, which in the end is decoded for the required speaker layout.
There are very few tools for this kind of pioneering work, allowing for the 16 channel wide tracks required by Third Order Ambisonic, Evo Channel is one of the best, allowing easy manipulation of several key components of a sound source; EQ, dynamics, and maintaining the vital phase relationship between channels, in one simple to use interface.
I use Evo Channel a lot and I am generally impressed with the sound quality and workflow, it’s been invaluable for me on my current project, ‘Notes from a Tremulous Hand’, a sonic novel full of grotesque characters and mysterious sonic anomalies, ‘pataphysics’ and the long neglected theories of Marconi -listen out.
Notes from a Tremulous Hand is available soon across several formats including an immersive binaural version (with or without head-tracking).Read More
Iconic audio designer Andrew Roth of San Francisco based Roth Audio Design has been creating immersive sound experiences for over two decades. His work runs the audio gamut. Working hand in hand with museums and theme parks, he designs, builds and installs immersive systems that create a life-changing audio experience. He also creates, records and mixes the audio content for these attractions. Beyond the museum and theme park work, he is often involved in audio work for film, television, radio, games, and web media where he often finds himself working in the rapidly growing field of immersive 3D audio experiences including interactive AR (augmented reality) and VR (virtual reality) as well as object oriented mixing. He provides sound design and mix services for all audio configurations including stereo, binaural, Ambisonic, 5.1, 7.1, and 7.1.4. With such a wide variety of audio work, it’s no surprise that SPAT Revolution is an integral part of his workflow.
SPAT Revolution, currently the most comprehensive real-time 3D-audio mixing engine available, provides its users the ability to control the position and add room effects to an audio-source in a three-dimensional sonic atmosphere. The results can be sent to a loudspeaker configuration or a pair of normal stereophonic headphones or the results can be exported as audio stems to be used within other audio engines such as Pro Tools or Cubase.
In discussing his current work, Mr. Roth explains, “It’s all over the map. There’s a lot of post-production. I’m in a studio where, you know, I do a lot of film and television. I used to do more games and things like that but I’ve gotten a lot more into installation work like theme parks, exhibits, museums and a lot into the binaural world as well which I’ve been interested in at least twenty years.” Roth actually began using an early version of SPAT back in the 90’s when a computer that was considered state of the art at the time had to struggle to keep up with the software application.
After pouring his heart into an audio design project making sure that every sound is exactly right and the mix has been meticulously tweaked, it only makes sense that he sees the project through the installation ensuring that there is no compromise made along the way even if that means disguising speakers in plants and/or burying cables in the installation. “While I like the comfort of the studio and the family life it affords me, I’ve found myself enjoying getting down and dirty. Some of the places I’ve been doing exhibits involve plants and dirt, you know, in the ground kind of cable running so that’s a nice change from the clean studio.” He continues, “With installations, one thing I found is when I would do audio for say a small theme park or something, I didn’t have any say in what I was designing for. They would say well this is the equipment, this is where the speakers are, these are the limitations. I’m still the sound designer at heart, but I like being able to bring the hardware installation as well because I can put in exactly what I know I want from beginning to end.”
Mr. Roth’s lifelong love of audio began as a child. He explains, “I’ve been interested in audio and sound in some form since before I was ten years old. There was a reel-to-reel machine in our house, in the basement, that was unused with a bunch of tape that was unused, stuff my father had bought before he had a kid and it had just been abandoned in the basement. So when I was nine or ten years old I started playing with that. I guess the immersive part just led me into the natural sounds world. I would stick friends and family members in a self-made sound chamber out of a tent and blankets with multiple speakers and I would play things like natural environments on records and cassettes and pump in music and just try to create environments in the dark.”
College paved the way for Mr. Roth’s passion for audio to expand, “It’s funny because I went to college at Oberlin, which is a conservatory and a regular liberal arts college in the Midwest so I could be near music and I studied eco-musicology and history and stuff like that. Sound was always just something I was sort of doing. I didn’t study it specifically.” A college internship at Earwax Productions (a sound design studio) eventually led to full time employment. Mr. Roth remained on board with Earwax for about five years until the dot com bust in 2001 or so and that was the birthing point of Roth Audio Design.
SPAT has become a necessity for Mr. Roth’s workflow as it allows him to audition his work in progress before actual installation has even begun. Wearing headphones for extended lengths of time can become fatiguing. SPAT resolves this by allowing Mr. Roth to recreate a binaural sound space in his 7.1.4 room recreating the binaural experience without wearing headphones allowing him to accurately mix for a binaural experience with or without headphones.
Mr. Roth is currently working on an installation in Golden Gate Park for the holidays that incorporates over seventy independent channels of audio across six rooms. SPAT allows Mr. Roth to virtually build each of the six rooms to utilize during the design process. “I can set up each of these rooms and can demo the design as it comes along. I can bring in the director of the museum and they can come to the studio and get an idea about the sound before it’s finished.” He goes on to say, “In those places where I recreate rainforests there are speakers in the ceiling, there are speakers in the floor for frogs and in the floor and birds in the ceiling and things around the horizon level. So I can demo that in the studio.”
Mr. Roth describes his utilization of SPAT Revolution, “What I’ve been hired to do a lot of is to do these immersive, very detailed and accurate historical recreations. I call them ‘audio-archaeology,’ where I try to take all the elements and put them together into a 3-D environment and I’ve done that with other binaural programs over the years. One thing that’s really cool about working with SPAT, and I’m about to do this for a museum in Sydney, Australia, is that it’s not bound to binaural. If I create a really detailed 3D recreation of say, San Francisco in 1906 with cable cars and all that, in the past it was a real pain to try and take that session then say remix it for a multichannel installation. Whereas now I kind of have this 3D environment and it’s not bound to its end mix. I can repurpose it much more easily.”The Enchanted Domain
