Is it possible to use plugins designed for FMOD Studio directly from low level api without using studio? Specifically I am interested in applying Steam Audio and Resonance Audio to ChannelGroup mix. Any hints?
The LowLevel API is used to load Plugins and contains the DSP class.
You can certainly use the plugins directly in the LowLevel API, some of our examples (that come with the API) do this and we have docs on this topic:
