Race Across The World is the BBC’s acclaimed adventure series where contestants travel across continents without flying, racing to reach the finish line using only ground transport and limited funds.

To promote the series, the BBC commissioned a 3D audio trailer designed to immerse listeners directly inside the journey.

ON THE SLY created the binaural audio mix for the trailer, placing the listener at the centre of the experience. Using spatial audio techniques, sound design positioned environments, movement and dialogue around the listener to recreate the feeling of travelling through unfamiliar places and shifting locations. The approach helped translate the scale and unpredictability of the race into an immersive audio moment that stood apart from a traditional trailer.

The project forms part of ON THE SLY’s wider work in immersive audio, broadcast storytelling and experiential sound design.
