Of course I couldn’t just go ahead and start composing whatever pops in to my mind since there were a few requirements. Most importantly, the ambient music would need to be looped over and over again for hours without getting on the players’ nerves. To ensure this, we decided to avoid making the ambient tracks too musical and instead try and make something that comfortably sits in the space between actual environmental sound effects (tumbling rocks, ancient mechanisms, dripping water etc.) and proper instrumental background music. Basically this meant some ambient hums and drones overlaid with subtle, slowly evolving abstract melodies topped with some eerie sound effects that are blended in to the rest of the ambient track. And for many of these elements, granular synthesis was the perfect tool.​
