What is a CNA file?

These files combine different streams of information like simulation settings and measurement data into one container.

CadnaA Projects: These files work with CadnaA software from DataKustik. They store detailed noise simulation projects and environmental data.
UnityFS Assets: A smaller group of CNA files use UnityFS format. They serve as asset containers for game data, such as AI Shoujo character details, and are handled with Unity asset editors.
