Audio Accessing global variables from within a Native Audio Plugin

Hi, and apologies up front for a newbie question. Just started working with Unity this month. I've written several Native Audio Plugins using Unity's SDK. What I'm trying to do is publish float values derived from the audio buffers in a native plugin to our render engine. For instance, I've written an FFT and derived bin values for low, min, and high frequencies, ranging between 0.0 and 1.0. I'd like to make that info available for animation changes in real time. Is there a way to do that? Thanks in advance.
