Because of recent technological advances with game hardware, sound designers have become able to apply real-time audio processing to their games in more creative ways.
In this GDC 2018 talk, PlatinumGames' Shuji Kohata explains the spatial audio techniques used in NieR: Automata's desolate landscapes and natural environments, and the noise and retro effects used to augment its mechanical themes.
It's an insightful talk that's definitely worth watching, so developers shouldn't miss the opportunity to do so now that it's freely available on the official GDC YouTube channel!
