FIFA is one of my favourite games so I read an interview with the woman who oversees the sound!
‘All of our audio work on FIFA is done entirely in-house. The Frostbite engine works similar to Unreal or Unity, where all assets in the game (such as audio, graphics, lighting and textures) are shared within the engine.’
‘We created audio scripts in Frostbite to automate tasks that we would normally do manually, established an audio post-production pipeline that was more efficient and organized, improved the implementation approach for stems and had more time to focus on audio polishing, our creative approach and the overall mix.’
From reading this interview I can see that in big commercial games frostbite seems to be the game engine of choice.
