Doha, Qatar – October 2020

Even in a skyline as futuristic as Qatar’s, the new National Museum of Qatar stands out as visually stunning. Designed by renowned architect Jean Nouvel, the museum’s modernistic exterior, adorned with 539 massive disks that lend it an almost other-worldly character, is home to more than 86,000 square feet of state-of-the-art exhibit space, with multiple interconnected galleries offering towering walls of video and immersive, multi-dimensional audio created using Flux::Immersive’s Spat Revolution.

The museum’s groundbreaking immersive audio design was created by Basel, Switzerland-based Idee und Klang, a pioneering multimedia agency acclaimed for their unique approach for integrating sound scenography with immersive audio design. The company has been working in immersive audio for more than 15 years, and as company founder Ramon De Marco explains, the Qatar project was unique on many levels.

“The museum itself is a very large and unusual space, with each of the galleries having its own architectural and acoustical character,” he offers.

“Each gallery has its own theme, with different video presentations and of course, different audio accompanying that, each one created by different composers and sound designers.”

With multi-channel sound and essential aspect of each gallery’s presentation, the complexities of producing and mixing multiple channels of audio for each space was just the beginning.

“We specified 64 channels for each gallery – almost 700 speakers in all,” reports audio scenographer and designer Daniel Teige. Meyer Sound provided the loudspeakers for the project, which was mixed using Spat Revolution.

Placement of the loudspeakers was also an issue, adds De Marco.

“The architects were adamant that they did not want to see any speakers. They originally wanted speakers only on the ceiling, which was about 20 meters high. Achieving any kind of directionality would have been pretty much impossible, and eventually we were able to lobby for locating some speakers at the bottom of the walls, where we had about eight centimeters of clearance. Meyer Sound had a compact speaker, the UP4slim, that we were able to implement in that limited space.”

Creating an immersive audio experience for even a single space can be a challenge, but creating multiple environments for adjoining spaces is an order of magnitude more complex.

“A lot of sound scenography is about understanding spaces, and how sound behaves in a space,” Teige observes.

“Using Spat, we were able to create a concept of how to deal with the sound, and adapt it to the theme of each gallery.”

” We compared several different immersive software programs, and Spat was really the most intuitive, as well as the best sonic quality. It’s far more than just a surround panner – it’s a room simulation tool that offers many opportunities to choose different algorithms ”

In addition to the sonic issues of overlap from adjacent galleries, De Marco points to the project’s sheer diversity as another challenge.

“We worked with each of the composers to create style guides, determine what sounds they would use, and how it would all be configured,” he observes.

“Most of the composers were more experienced in composing for TV documentaries, and not necessarily accustomed to creating for multichannel immersive environments. We worked with them not only in terms of what kind of sounds they would use, but also the material they would deliver, so we were able to adapt it to 50 or 60 channel mixes. Instead of receiving one or two WAV files, we were getting 50 or 60 files to orchestrate into a space.”

Consistency was also a factor, he adds. “We received everything from perfectly assembled multichannel sessions to some rather challenging ones. In some cases, we did a big part of the sound design ourselves, because the material we received was simply not enough.”

Composer Stratis Skandalakis has a long history of creating immersive compositions for exhibitions, including travelling globally to gather field recordings for his work. Skandalakis worked with a wide array of composers and circumstances, mixing each of the projects using Spat Revolution.

“It was pretty challenging at times,” he reports.

“Some of the composers had no previous experience with multichannel mixing, and were not accustomed to having a conversation about for example, where to place a sound in a 360-degree space. Often I would be working with a director on my left, and a sound designer on my right, and dealing with a very complex mix with maybe 50 channels, explaining why it takes time for the additional sound design.”

Skandalakis points to working with Spat as key to addressing the widely diverse range of material the team had to work with.

“It was a first for me to work with multiple formats at the same time,” he observes.

“With Spat we were able to take stereo, mono, ambisonic, 5.1, and throw them all together. It was a great tool for sound design and for special effects as well. You can make very fast movements, really play with the object based mixing.”

Particularly with the compressed timeframe, there was not a lot of opportunity for long involved mixing sessions. Staging and designing the systems in advance was key to making it work, and much of the planning and acoustic modeling was begun at the Idee und Klang studios in Basel.

Working with Spat Revolution was a tremendous time-saver, says Teige, enabling the team to create the initial sound design quickly and efficiently before taking it to the actual galleries for fine tuning.

“You have an idea and you want to implement it quickly,” says Teige.

“Spat’s object based mixing is really intuitive to work with, and that enabled us to stay in the creative space and work fast and efficiently.”

For De Marco and the Idee und Klang team, this was their first experience working with Spat Revolution.

“We compared several different immersive software programs, and Spat was really the most intuitive, as well as the best sonic quality,” he observes.

“It’s far more than just a surround panner – it’s a room simulation tool that offers many opportunities to choose different algorithms. And the people at Flux were great to work with. Gaël and the others were really supportive. Any time we ran into an issue, we would call and right away, we would have a new update. Spat is really the only software I would choose for a project like this one.”

Jinan, China – October 2020

When China’s Jinan Olympic Center Donghe Stadium opened its doors to the public on September 16, the Ministry of Culture and Tourism and the Shandong Provincial People’s Government co-sponsored a remarkable symphonic presentation, treating the audience of 2000 to the region’s first immersive orchestral performance.

The “Yellow River Flowing Into the Sea” concert featured an orchestra of nearly 160 pieces, as well as an 800-person chorus and guest appearances by nearly a dozen famous singers. The massive event utilized the power of Flux:: Immersive Spat Revolution to bring the audience inside the music.

FOH engineer Yong Xu mixed the show on an SSL L500 with L100 sidecar, integrated with dual Spat Revolution workstations running dedicated 8-core i9 computers, while OB engineer Wenzhao Ma ran a DiGiCo SD7 Quantum, also using dual Spat Revolution system. MADI connectivity via MGB devices ensured full redundancy.

“We used Spat on both the live and OB production,” reports systems engineer Wenzhao Ma.

“We divided the orchestra into 15 stereo stems and one mono stem to the FOH desk, and then flowed it into Spat using MADI. For the OB mix, I tried to put all the inputs into Spat, including functional channels like background music, ambient and audience mics. I did not use reverb tails on those elements, but but I used the acoustic simulation in Spat’s room effect to leave a little bit of early reflections, to give a sense of space.”

” We divided the orchestra into 15 stereo stems and one mono stem to the FOH desk, and then flowed it into Spat using MADI. ”

The object-based FOH mix consisted of more than 20 stems from the SSL console, with Spat Revolution rendering the mix to the LCR system to provide imaging and acoustic simulation. At the OB position, a mix of 21 stereo stems and two mono stems from the DiGiCo console utilized Spat to render stereo, 5.1 surround, and full binaural synthesis mixes.

For Wenzhao, the show was his first experience working with Spat, and he was more than impressed.

“The functions are powerful, and the sound is amazing,” he enthuses.

“I really like the flexibility to be able to work in any configuration, even on headphones. Immersive and spatial audio is more than just a technical ‘trick’ – it enables us to improve and enhance the sound and the performance by adding dimension. Spat gives me the flexibility to show the composers what surprises are possible with their creations.”

As Wenzhao explains, the stadium required a fair amount of preparation for the event.

“The Jinan Donghe Stadium is a normal sporting venue, not really designed for music events. We had to build a stage and create special rigs to hang the LCR loudspeaker system from a wire.”

Each column comprised six d&b Audiotechnik GLS8 and two GSL12 boxes. Twelve SL-SUBs were stacked in front of the stage.

“We really wanted to hang the subs as well, to avoid too much low-frequency build-up in the front rows, but the weight restrictions prevented us from doing that,” adds Wenzhao.

Two groups of sidefills utilizing SE Audiotechnik M-F3a units were processed in mono.

” I will be presenting this recording to some of our clients, and I will be changing it to a 5.1 or 7 channel mix. With Spat, that is so easy to accomplish. ”

The live recording of the event also added to the challenges, Wenzhao reports.

“The event was being recorded for Blu-Ray, and the recording engineer Mr. Jakob Handel had specified using DPA4099 mics on the strings. We were a bit concerned about capturing a good sound on the strings, as the mics also picked up much of the sound of the brass. But then we found that using Spat to add some natural depth and dimension to the strings solved the problem perfectly; I didn’t even need to any EQ to the strings.”

Wenzhao also gives high marks to the Flux:: Immersive team for their support.

“I think I have read almost an entire e-book from Mr. Hugo Larin and the rest of the team,” he quips. “They really helped us a lot through a challenging setup.”. “One thing that I love about Spat is the ability to easily reconfigure the channel setup,” observes Wenzhao.

“I will be presenting this recording to some of our clients, and I will be changing it to a 5.1 or 7 channel mix. With Spat, that is so easy to accomplish.”, “The show was a great success,” reports Wenzhao.

“I will most certainly be using Spat Revolution for future projects. Our team had the first application of Spat in China, and it is just the beginning. We have a studio in Beijing, and we will create a Spat setup there. I have plans to use it for many upcoming projects.”

Milan, Italy – September 2020

To say that Sabino Cannone is a busy man is like calling the Nile River a small stream. Cannone likely has more entries in his calendar in a typical week than most of us have in several months. He moves seamlessly from engineering to mixing and mastering, sound design, consulting, and a dizzying range of other projects, clearly loving every minute of his busy schedule.

Cannone is also no stranger to new technology, including being an early adopter of immersive audio.

“I started with the first 5.1-compatible version of Pro Tools, 20 years ago,” he reveals.

“I mixed the show Pinocchio in Italy, which was the first musical in Europe to use surround. It was a big show – we did a 6.1 mix, as well as a live band – in a large theater; it was a very complex production. The show is still running, and still using the music I did 20 years ago. They did a run on Broadway three years ago, and I also mixed the soundtrack recording in 5.1 surround.”

Several other musicals in surround would follow, as well as a number of installations for visual artists in Italy, Portugal, and Spain. As immersive audio evolved to encompass an ever-widening realm of potential formats, Cannone continued to dive deeper, dabbling in soundscapes for movies, games, and exhibitions. Recently this has included a number of projects using Spat Revolution from Flux:: Immersive.

Cannone’s introduction to Spat Revolution came at the tail end of a project with long-time collaborator David Kahne, creating an immersive sonic environment for National Geographic Encounter: Ocean Odyssey, an installation in New York’s Times Square. As he explains, it was toward the end of the National Geographic project that he first encountered Spat Revolution.

” With Spat Revolution I can do a mix in 5.1 and it will work in 7.1, or in 20.2, it can really adapt to whatever format I need. That’s not just a huge time saver for me, but it also makes it easy for me to explore new creative ideas – It’s a great tool! ”

“In the National Geographic project, we had lots of different environments, with different formats and channel counts. David was the head of the project, and I worked with him in the sound development, creating multichannel soundscapes, as well as the final immersive mix in New York. We both worked in Nuendo, and I also used Pro Tools for the sound development.

We were pretty much done with the mixes when the Flux guys asked me to check out the very first version of Spat Revolution. I started using it for the last part of the soundscape development, and I was blown away with how powerful it was. You were free to create whatever format and channel count you wanted – it was absolutely portable to any setup. I could mix multiple stereo sources to create soundscapes in any format. I created several 5.1 and 7.1 libraries, and used it on some final mixes. I decided right then that I would use it on my next project too.”

That versatility, and the ability to adapt each mix to virtually any multichannel format, was a major factor in his enthusiasm for the program.

“The Ocean Odyssey exhibition is spread over several different rooms,” he observes. “Each room and environment uses several different speaker combinations. The possibility to not have to redo the mix for each venue on installations like this one is a big value for us.”

Spat’s object based protocol was a new concept, Cannone explains.

“This was my first time working in object-based mixing, and I will admit it took some getting used to. For me, the focus of the sound is the most important factor. With object based mixing, you have a lot more freedom in movement of sounds, but with that freedom it becomes more challenging to maintain focus. It was a challenge at first, but once I understood how to manage objects, it was amazing how much easier it was. I think it was good for me that my first experience was using it on a very complex project, with so many options, because it really pushed me to learn about how to keep things in focus.”

Maintaining focus and balance in the mix is important in any format, but even more so when working in immersive, says Cannone.

“I think before you can understand working in immersive, you have to understand balance. All the sounds have to sit nicely in a stereo field before you can spread them to a surround field. And even before stereo, the mix must work in mono. I work a lot in mono – that’s another thing I learned from David Kahne. It’s funny – if you listen to those old Motown recordings, they were all done in mono, and yet they almost sound like stereo, because of the space and the balance. It all goes back to the way the brain perceives sound.”

Needless to say, Cannone is still enthralled with working in immersive audio, and enthused to explore the potential of working with Spat Revolution.

“We have come very far from the early days of immersive,” he points out.

“Years ago, when you did a mix in 5.1 surround, it was only for 5.1. With Spat Revolution, I can do a mix in 5.1 and it will work in 7.1, in 20.2, it can really adapt to whatever format I need. That’s not just a huge time saver for me, but it also makes it easy for me to explore new creative ideas. It’s a great tool.”

Toulouse, France – August 2020

Veteran live sound engineer Johnny Torchy has spent many years mixing shows across his native France and the rest of Europe. He’s also known as an early adopter, and isn’t afraid to try out new tools and technologies in his work.
Most recently Torchy has been driving the faders for French melodic rockers Neko Light Orchestra.

In celebration of the band’s eight anniversary, Neko Light Orchestra booked the 800-seat Le Bascala, in the Bruguières district of Toulouse, for their “Marathon Musical Festival,” featuring eight concerts in 12 hours. As if that wasn’t enough of a challenge, the decision was made to present the show in an immersive environment.

Torchy says the goal was to recreate the location of the various musicians on stage – up to 13 members – while creating a sense of depth using advanced room acoustics simulation. To meet the challenge, Torchy chose object-based immersive mixing via Spat Revolution and Wave Field Synthesis technology.

“Part of the challenge was that WFS typically calls for a large number of loudspeakers to create reliable results,” Torchy observes.

“But in fact, for this project I’ve used only seven line array sources, all in front of the audience. The results were very impressive.”

Torchy’s system utilized seven clusters of four L-Acoustic KARA loudspeakers facing the audience, with seven stacks of two KIVA cabinets on stage lip for front fill. Driving the mix was a Yamaha CL5 console equipped with a Rio 3224D I/O box bringing in 60 inputs. System connectivity was via a Dante DVS network, with a MacBook Pro running FLUX:: Immersive Spat Revolution.

“Most of the sources were sent post-fader to Spat Revolution, except for a few of the more complex instruments using multiple microphones, like piano, harp, and string sections, where we sent summed stems.” Torchy explains.

” Whatever the placement of each musical object, I was able to use Spat Revolution WFS to create the image I had created in the studio. I don’t know of any other system that can do this over such a wide audience area. ”

Using Spat Revolution’s advanced reverb engine enabled Torchy to perform advanced acoustic simulation, recreating perceived dimension and space in ways traditional consoles and PA systems cannot achieve.

“I was shocked,” Torchy reports.

“The sensation was simply incredible. You could literally make the source disappear. Of course there’s still sound coming from the loudspeakers, but the speakers themselves literally become transparent, with the actual wavefront of the source objects dominating. It’s no longer the same as mixing at a console with left and right channel. Its more like mixing in a virtual room, created in Spat Revolution.”

Torchy had previously built a smaller seven-speaker setup to test the system and do preproduction, but the impact in a live setting was simply remarkable.

“With Spat and WFS, I’m able to transmit the imaging and the artistic emotion not just to 15 or 20 percent of the audience that’s seated in the middle, but to the entire audience,” he enthuses. “Whatever the placement of each musical object, I was able to use Spat Revolution WFS to create the image I had created in the studio. I don’t know of any other system that can do this over such a wide audience area.”

For Torchy, this was an experience he will not soon forget.

“It was beyond any other setup I’ve ever deployed. It will be hard to go back to anything less.”

FLUX:: IRCAM Spat Revolution is an object-based immersive audio mixing suite that includes a stand-alone rendering and processing application, and a set of plugins for audio and automation integration with various DAW hosts.

Spat Revolution renders virtual environments (Rooms) using a variety of spatialization techniques and panning protocols, and integrates the fundamental channel and scene-based approaches; Ambisonics and HOA.

While rendering to loudspeakers, which often is the final destination, one of the most often-used techniques in Spat Revolution relies on binaural synthesis and the ability to render the source objects, arbitrarily positioned in a virtual environment, to a pair of standard headphones using the same two audio channels.

Binaural takes two forms: First, binaural can be chosen as a stream type in order to virtualize every individual source-object and the room effect (acoustic simulation) of a Spat Revolution room (your object-based mix). This is the ideal scenario when creating content for live streaming, or for bouncing the two audio channels as a binaural deliverable.

Because multiple rooms are supported, some scenarios may include having some source objects connected to a binaural room, while others are connected to a standard stereo room. This strategy enables the mixer to, for example, keep some instruments that are rich in transients, like a kick drum in a stereo pan law, very much locked in between the ears. A simple summation then returns everything together in the headphone mix in the end.

The second form of binaural is binaural monitoring. This makes it possible to audition any channel-based speaker arrangements over your headphones. In this particular case, you are virtualizing each speaker as a source, which is extremely convenient when you don’t have access to the diffusion system you are preparing the content for.

In the two binaural modules in Spat Revolution, Room or Monitoring, there is an option to choose an HRTF. By default the HRTF used is Kemar, though this can be changed in the set up in the Spat Revolution preferences page.

The post Creating binaural content with Spat Revolution appeared first on FLUX:: IMMERSIVE.

Using binaural audio means dealing with HRTFs. In the HRTF section in the Spat Revolution preferences menu, you can access and manage HRTFs. The HRTF used by default is Kemar, which can of course be changed and another HRTF can be set up as default instead.

In the Manage HRTF section you have access to a database listing locally available and downloadable HRTFs. When an HRTF is downloaded, or locally available on your computer, you can set up, with Include or Exclude, which HRTFs are displayed as available in the Spat Revolution Binaural Room or Binaural Monitoring modules.

As an example, the KU100 Neumann HRTF, commonly used in 360/VR pipelines and in VR SDKs (Google, YouTube, etc.), is available in the database and can be downloaded and included in your workflow.

Choosing the KU100 Neumann as the default HRTF will assure it is selected automatically every time you use a Binaural Room or Binaural Monitor module.

If you are fortunate enough to have your own HRTF, you can simply import your file to Spat Revolution in a few simple steps. First, verify that your HRTF is using a SOFA file format and that it’s Diffuse Field Equalized – this means that the direction-independent component in the HRTF is removed. This direction-dependent component is referred to as a DTF (Direct Transfer Function) version. Supported are SimpleFreeFieldHRIR or SimpleFreeFieldSOS IIR. HRTF Modeled as IIR filters are preferred.

Ideally, your file name ends with SampleRate.SOFA. With this file name structure, Spat Revolution will import all your HRTFs as one single entity, with various sample rates available. (Without this file name structure, each sample rate will be imported as a separate HRTF, which is not as convenient. File example “My HRTF name”_44100.sofa “My HRTF name”_48000.sofa :My HRTF name”_96000.sofa)

Importing your HRTF to Spat Revolution will require four simple steps:

1. Locate your files and open Spat Revolution.

2. Go to Preferences, HRTF section, Manage HRTFs.

3. Press the import button and select your .SOFA files (You can select all sample rates).

4. Make sure to choose the DTF version of your HRTF.

Success!

When your HRTFs are imported, you will see them as available files, which from now on will automatically be included in your Spat Revolution software preferences. Your last step is to simply choose your HRTF as the default in the HRTF section in the Spat Revolution preferences.

The post Managing and Importing HRTF appeared first on FLUX:: IMMERSIVE.

Using the generic Kemar HRTF provided as a default for binaural in Spat Revolution, or downloading any of the popular HRTFs used in 360/VR pipelines such as the Neumann KU 100, is where binaural starts. Achieving a more accurate and reliable monitoring experience, with a far more natural sense of space and direction, can be achieved with your own individual HRTF.

Unfortunately, a personalized HRTF is not easy to come by. Some laboratories do offer them, but the expense makes them largely impractical for most engineers.

Rest assured, the Genelec Aural ID and a simple import of your HRTF file into FLUX: IRCAM Spat Revolution will have you covered here.

Some background. Our head, outer ear shapes, and head movements provide us with a wonderful ability to localize sound sources, which is why monitoring over loudspeakers works so effectively. Headphones, however, break the link to these natural mechanisms we have acquired over our lifetime, making it harder to localize sounds, since sounds from headphones seem to reside ‘inside’ our heads rather than all around us.

The Aural ID computes how your head, external ear, and upper body affect and color audio arriving from any given direction. This effect is called Head-Related Transfer Function (HRTF), and is unique to each user. The Aural ID calculates your individual HRTF by modeling your personal head and upper torso features, and creates a file that can be integrated into your Spat Revolution audio workstation. All thanks to the SOFA file format supported by Genelec and FLUX:: IRCAM.

For more information on managing and importing HRTFs read the Managing and Importing HRTF article.
