For the production of The Last Ship Sound Designer, Sebastian Frost utilised d&b audiotechnik Soundscape.

d&b audiotechnik Soundscape a unique signal processing technology, with two optional software modules: En-Scene a sound object positioning tool, and En-Space which allows designers to add room emulation of reverberation signatures particular to any given space, real or imagined. Frost harnessed this technology to his own vision of how the musical should be perceived and enjoyed by all audience members.

“I went to hear a demo in Hall 14 at d&b HQ in Backnang about a year ago.” Frost commented.

“The experience was inspirational because the biggest thing you want from any system is that it doesn’t tie you down or restrict you in any way. Currently, there is a great deal of chatter in audio circles about creating immersive experiences or 3D sound environments, that’s not what’s happening here.

Frost explained: “What I heard was much more than simple panning or delay of sound; you were not just placing sound objects in specific places. This was a more scientific approach… this was the creation of a sound field within which the creative possibilities appear unrestricted.”

Recognising the specific demands of musical theatre, d&b then arranged a more applicable demonstration. “The Everyman Theatre in Cheltenham is a typical multi-level theatre, whereas Hall 14 was a full 360-degree environment you could walk around and through. Exciting as that was, having the opportunity to play around, to see if we could combine Soundscape with a more conventional proscenium style deployed system was ideal.

What was immediately apparent was that as I went into the theatre it had the same effect I’d heard in Backnang; that effect is that the sound field is opened up to the entire audience. In that sense hearing is transformational.”

Beyond his own desire to ‘open the sound field’ to the entire audience, the Last Ship presented Frost with a second strong justification for implementing Soundscape.

“When I sat with The Last Ship designers 59 Productions and director Lorne Campbell there was one aspect of Northern Stage that affected everything. The stage is wide and relatively speaking not so high. What they wanted was a clean line to stage so they could use full height and width to accommodate large-scale scenic video projection. Typically, they would have used a line array system of some sort at this venue, but that was not a realistic option with the video projection being contemplated.”

As well as the installation of multiple loudspeakers throughout the auditorium, the technical parameters of Soundscape require a horizontal array of discrete sound sources across the top of the stage. While these can be line arrays, it’s also perfectly practical to use point-source loudspeakers, which is where Frost saw the advantage.

As Northern Stage’s Production Manager Chris Durant observed. “Here we have 6 d&b audiotechnik V10P across the proscenium, each laid horizontal with the horn rotated to present the 110 degrees wide dispersion. Six Y10P are down the room on the delay line, and there are 12 twelve front fills. The Y-SUBs are all tucked away up on a bridge above the audience. We would normally struggle here with loudspeaker positions with relationship to lighting positions and sightlines, and in this case, we have scenic projection to consider which only makes that harder. But instead, nothing intrudes. At most there is the E6 front fills across the stage, but that’s it.”

With direct support from d&b audiotechnik, contracted audio supplier Stage Sound Services took Frost’s design concept, made the ArrayCalc assessment of the auditorium and installed the system with Frost’s Production Engineer Owen Lewis, assisted by Durant’s house team.

“The system went in quickly and easily and sounded good the moment we turned it on” continued Frost. “Because it sounded good from the off we were in a good enough place to be able to experiment and play around immediately with the creative elements. Having the freedom to put the band where to be  proved highly advantageous, here they were physically positioned off stage left, but for most of the show I have most of the instruments placed around the stage as a whole.”

“This idea that you are within a sound field presents a different listening experience for the audience. Normally if you sit in the front rows close to the front fills what you hear is a simple mono source… Not with this system. Relative to where you happen to sit each loudspeaker is delivering something subtly different, but as a listener you are completely unaware, tilt your head to one side or the other and the loudspeakers are completely indiscernible.”

“There are several thousand positioning cues, maybe ten times as many cues than an average musical. Without the 4.2 beta version of QLab which we got just before the show, managing that would just not have been possible to do. The analogy with lighting holds; I had to say to the actors, ‘your positions on stage are really important, we do need you in the same place at the same time.’

However, we don’t want to straight jacket the actors and once Joe [Sound No.1] had comfortably passed the point where he felt he needed to have his head in the book, he found instead he could keep his attention on the actors and cue to them – so they had some freedom.”

Beyond Frost’s masterful use of En-Scene to provide an authentic source oriented listening experience, he also used the En-Space function to great effect, most noticeably for an intimate scene between two actors placed within a video projected medieval stone built chapel. Producing that distinctive reverberation, and as an added touch, making it appear to emanate directly from that space on stage as if we the audience were sat distanced from the protagonists at the opposite end of the nave.

Joe Green, who programmed all those cues into the desk, commented “… the cast hear themselves as the audience do, it’s self-monitoring. They are not subjected to hearing a power-alley come back at them from the room. Everybody gains, audience and cast alike.”

Nick Newman, the touring board operator, added. “For set-up, you will spend less time listening and setting the delays; that process of moving around the auditorium trying to blend the transitions between different elements of the system – as you would with a conventional PA for a musical. Instead, you will just spend a bit more time at load-in actually getting it set accurately in the positions plotted in ArrayCalc.”

Frost added: “But here the thing is getting it right in ArrayCalc means that when Soundscape is ported into R1 and thence to the system we had to do very little… Normally with something say like the coupling of the low-mids, you look at one box and it produces a certain result. Look at the whole horizontal array and when you measure you get another result, and then you have to go back and work through them till the system responds as you want. With Soundscape, once it was in that all became straightforward.”

“The audience don’t necessarily know what has happened, but everyone comes out the theatre saying the voices are fantastic. To be honest, the way it has worked with the show has changed the possibilities of sound design throughout the genre.”
