Hybrid Audio Production Models Bring AI And Human Craft Into Alignment

A distinct pattern emerged as this year's Cannes Lions Audio & Radio jury discussed the strongest contenders for the industry's top honors. In AI driven work, campaigns that treated the technology mainly as a shortcut for reducing costs or accelerating production often lacked emotional impact. The most compelling entries used AI within a broader creative process, where human judgment, sensitivity and collaboration remained central. The strongest work suggested a clear direction for the industry: technology is most effective when it expands human creativity rather than attempting to replace it.

Edu Luke is the Founder and Sound Creative at HEFTY Music & Sound, the São Paulo studio he has led for 11 years. Raised in a family of professional musicians, he describes his role as that of a "sound actor," shaping the studio's work to match the emotional character of each campaign. HEFTY has contributed to work recognized with 71 Cannes Lions, including six Grand Prix, as well as a 2025 Latin Grammy nominated music video. In 2026, Luke served on the Cannes Lions Audio & Radio jury, giving him a close view of how the industry is evaluating the role of AI in creative work.

"Right now, we are still operating in a grey area. We work with clients in many countries, and each region has its own interpretation of what is ethical and permitted, what is restricted and how AI cloning should be handled," Luke says. The absence of a shared framework is also reflected in industry judging rooms, where different perspectives and standards meet.

For Luke, the discussions around Hyundai's Coquí Alarmed campaign, which received the Audio & Radio Grand Prix, illustrated the value of collective deliberation. Entered in the Single Market category and deeply rooted in Puerto Rican culture, the idea did not immediately command the same attention as work coming from larger markets, while the jury was still engaged in broader discussions around scale and global relevance. But once the room took the time to examine the campaign in depth, its strength became undeniable. It ultimately checked every box the jury had been looking for in a Grand Prix: a genuine cultural insight, a clear and relevant role for the brand, an inventive use of audio, meaningful impact and an idea that could only exist within that specific context.

"That was the beauty of live judging," Luke says. "It gave us the time to move beyond first impressions, challenge our assumptions and recognize that a deeply local idea can carry universal power."

The emotional depth test

The same demand for depth also revealed the limitations of some AI-focused entries. Several campaigns appeared promising at first, but lost emotional impact when the jury considered how the finished work would truly connect with people. Two entries in the same category illustrated that contrast clearly.

"One idea invited parents to record their voices and help build a free library of stories, created primarily for children who are blind," Luke explains. "It felt deeply human and emotionally powerful. Another concept used AI to generate personalized stories through an app. The idea was interesting, but the final experience did not create the same emotional connection. That contrast reinforced how essential human sensitivity remains."

The same principle showed up in categories where the creative team has to do most of the emotional heavy lifting. Luke points to the Gold-winning campaign Searching for Birds on Wires as an example of what happens when a team commits to that emotional depth in a category where audiences have no pre-built affinity for the brand. "Helping an electric power company is incredibly challenging because nobody wakes up excited about paying their bills," notes Luke.

"For a power company, creating affection can be especially challenging, because most people experience the brand through something as functional as paying a bill," Luke says. "Changing that perception requires a genuinely sensitive idea. Technology can support the process, but it cannot replace the human judgment and emotional understanding needed to create a meaningful connection. That was one of the strongest lessons for me and for the entire jury."

Beyond the viral video pitch

The limitations the jury observed in work that relied too heavily on AI also helped shape Luke's perspective on how the technology should be used in professional production. At HEFTY, AI serves as a carefully controlled starting point, supporting research, prototyping and selected early stages of the process, while creative judgment, craft and final delivery remain firmly in human hands.

"Yes, we need to embrace AI as a technology that can help us, but we cannot allow it to become a distraction or a lazy shortcut," Luke says. "Our mission is not to reduce costs at the expense of the work. It is to create meaningful connections between brands and people."

Luke applies the same perspective to the growing wave of viral AI demonstrations shared across industry platforms. These examples can be impressive, but they rarely reflect the complexity of a real client project, which involves multiple stakeholders, approval stages, legal considerations and demanding craft standards.

"Many of those videos suggest that a complete film can be produced in two hours for just a few dollars," Luke says. "But once you move into a real commercial environment, with a real brief, a real approval chain and a high standard of execution, the process becomes much more complex. The technology is evolving quickly, but there is still a significant difference between a viral experiment and a finished professional production."

Prototypes and pending rulings

At HEFTY, AI is used selectively and within clearly defined, human supervised stages of the workflow. The team applies it to early song exploration, audio restoration and temporary voice references that support internal development and client approvals. When voice technology is involved, HEFTY works only within authorized contexts, using licensed or properly approved models. Creative decisions, final performances and finished deliveries remain guided by human professionals.

On the business side, Luke also uses operational and legal tools to reduce repetitive administrative work and allow the team to focus more deeply on collaboration, craft and creative judgment. "The smartest approach is hybrid collaboration, using AI as a tool that helps people do their best work rather than attempting to replace them," Luke says.

The area Luke is watching most closely is voice cloning. For a studio that works across multiple markets, the issue involves not only technology, but also consent, authorship, licensing and the protection of performers and composers. Regulations and industry standards are still developing, often at different speeds across countries and platforms.

"There is a great deal happening behind the technology, from legal discussions and corporate interests to the rights of artists, composers and performers," Luke says. "What the industry needs most is a clear and consistent framework that protects creators while allowing responsible innovation. I hope we move closer to that clarity over the next year."
