What’s the difference between lowlevel and studio?
The FMOD Studio API is the programmer interface to load FMOD Studio banks and trigger events authored by the sound designer. The FMOD Studio Low Level API is the programmer interface that doesn’t require any tools, and is just for triggering simple sounds.
We have recently added an overview of the LowLevel, which may help to understand it a bit better:
You can use the LowLevel API on it’s own, whereas the Studio API works on top of the LowLevel. When you create a StudioSystem it will make it’s own LowLevelSystem which you can access, using Studio::System::getLowLevelSystem(), and use as you would if you were just using the LowLevel API.
