The art of location-based Sound Recording specifically, has been a neglected area of academic research. I seek to address this by drawing critical attention to the intricacies and skills involved in location Sound Recording within Realist filmmaking – both scripted and unscripted. I show how this art continues to be central to the creative process of production, in driving the narrative and shaping the text’s influence, within the pro-filmic space. Realist filmmaking aims to create a sense that “…there’s no separation between the audience watching the film and the events in the film.” I explore the potential contribution of an immersive location Sound Recording methodology on the prevailing, classic single camera, ‘2D’ filming methodology, and how this might then contribute to the reinvigoration or reimagining of the Realist/ Observational Documentary genre, in an age of immersive media - specifically suggesting that ambisonic audio would contribute to this.
