In "Berlin Syndrome," the soundscape becomes a character of its own, weaving tension and unease into every scene. Robert Mackenzie, alongside Luke Mynott, crafts an immersive auditory experience that captures the claustrophobia and suspense of Clare's entrapment. The film's sound design, recognized with awards from the Australian Screen Sound Guild for Best Achievement in Sound for Film Sound Recording and Mixing, intricately layers ambient city noises with the eerie silence of isolation. Each creak and whisper is meticulously placed, drawing the audience deeper into Clare's harrowing ordeal, making the sound an integral part of the storytelling.
