Perhaps the most pervasive immersive format at present is 360° video, which can be panned whilst being viewed. Typically, such footage is captured with a specialist camera. Approaches and workflow for the creation of 3-D audio for this medium are seldom documented, and methods are often heuristic. This paper offers insight into such approaches, and whilst centered on post-production, also discusses some aspects of audio capture. This is done via a number of case studies that draw from the commercial work of immersive-audio company, 1.618 Digital. Although these case studies are unified by certain common approaches, they also include unusual aspects such as binaural recording of insects, sonic capture of moving vehicles and the use of drones
