The 141st Audio Engineering Society Convention, held recently in the Los Angeles Convention Center’s West Hall, attracted a record West Coast attendance, with a wide cross-section of brands showing their wares on the exhibition floor and companion demo rooms. Aimed squarely at evolving technologies via a special focus on new markets and trends, the four-day convention took the highly appropriate theme of Immersed in Audio. “That pretty well sums up where [our industry] needs to move forward in the world of new audio technologies,” noted AES president John Krivit. “Sound for picture, networked audio and game audio were all covered here with a full technical program of workshops, tutorials and exhibits.”

The co-located Audio for Virtual and Augmented Reality Conference drew standing-room-only attendance in a lecture theatre and companion papers room. Originally expected to attract some 290 attendees, aggressive outreach to the VR and AR communities proved so successful that pre-registration for the inaugural two-day event had to be closed at just over 400, with sponsorship from Audiokinetic Dolby, DTS, Dysonics, Gaudio, Nokia, Occulus, Sennheiser, Source Sound and VisiSonics.

“Just as TV programming progressed from live broadcasts of staged performances to today’s complex language of multi-thread, long-form content, so such media will progress from projecting existing media language into a headset experience to a new VR/AR/MR-specific language that both creatives and audiences understand,” keynote speaker Philip Lelyveld stressed.

Targeted squarely at the rapidly growing field of virtual and augmented reality audio, the program focused on the AR/VR creative process, applications workflow and product development. “Film director George Lucas once stated that sound represents 50 percent of the motion picture experience,” offered conference co-chair and AES past president Andres Mayo. “Our conference demonstrated that VR and AR productions require audio that follows the motions of the subject, and produces a realistic immersive experience.”

The event was bookended by two keynotes from leading VR/AR proponents. The first, presented by Philip Lelyveld from the USC Entertainment Technology Center and entitled The Journey into Virtual and Augmented Reality, defined how virtual, augmented and mixed reality will impact entertainment, learning and social interaction. “Just as TV programming progressed from live broadcasts of staged performances to today’s complex language of multi-thread, long-form content, so such media will progress from projecting existing media language into a headset experience to a new VR/AR/MR-specific language that both creatives and audiences understand,” Lelyveld stressed.

The closing keynote from George Sanger, director of sonic arts at Magic Leap, and entitled Future Nostalgia, Here and Now: Let’s Look Back on Today from 20 Years Hence, tried to predict where VR/AR/MR will be in two decades. “Two decades of progress can change how we live and think in ways that boggle the mind,” he acknowledged. “Twenty years ago, PCs had rudimentary sound cards; now an entire multi-track recording studio lives on our computers. By 2036, [consumers] will be wearing lightweight portable devices all day. Our media experience will seamlessly merge the digital and physical worlds; how we listen to music will change dramatically. We live in the revolution of possibilities,” he concluded.

Several sessions from the convention’s Sound for Picture Track offered valuable insights for the film and TV post community. As session chair Brian McCarty from Coral Sea Studios, Australia, stated, “The world’s largest group of working sound engineers are those handling sound for picture, a community that is dramatically expanding.”

During the World-Class Film and TV Sound Design panel, Lon Bender, MPSE, from Formosa Group and Brett Hinton from Atomic Sound discussed how sound designers work with film directors and TV producers to develop fully detailed soundtracks. Bender, whose extensive credits as supervising sound editor include The Revenant and Hunger Games, offered, “Sound is a subjective element; we try to understand the director’s and the film editor’s ideas and develop a common language. We need to concentrate on subtexts and the overall feeling of a scene. I like to use organic sounds to design the soundtrack.”

From comments secured during the spotting session, Bender said he begins to “fully understand the director’s requirements. Although I will develop audio sketches from an early picture cut, [directors] need to understand that it’s just a sketch and not the final product. We cannot rush the process; it takes time to develop a soundtrack, all the way to the final mix. My sound design can help re-recording mixers understand the sonic balance within a soundtrack. Our team success comes from continuing collaboration.”

“Sound is a subjective element,” said Lon Bender. “We try to understand the director’s and the film editor’s ideas and develop a common language. We need to concentrate on subtexts and the overall feeling of a scene. I like to use organic sounds to design the soundtrack.”

In contrast, Hinton stated that his schedule on TV shows like Falling Water, which premiers on USA Network in mid-October, is more accelerated. “But the process still starts with the script,” he acknowledged. “I look at what is happening story-wise and determine what sounds would support the [narrative]. During the spotting session with the post supervisor — and, hopefully, the show runner — I’ll sketch ideas about the sound design, and how it fits with the dialogue, sound effects and Foley elements. We have seven, maybe 14 days from picture turnover to the final dub, with maybe two re-conforms before the dub — conform software definitely is our friend! — and then maybe two more on the stage, but with not as many edits. We can also retain volume and pan automation.”

During the Immersive Sound Design for Film & TV panel, presented by Nuno Fonseca from ESTG/Polytechnic Institute of Leiria in Portugal, Benjamin Cook (Starz series Black Sails), Jason Jennings (Teenage Mutant Ninja Turtles: Out of the Shadows) and Mark Mangini, MPSE (who secured an Oscar win for director George Miller’s Mad Max: Fury Road), focused on immersive-sound formats used for film and TV shows. “Design of realistic and engaging immersive sound fields is challenging this fast-paced production environment,” Fonseca offered. The Hollywood-based sound designers shared their experiences crafting immersive sound fields and their use of specialty sound design tools.
