Audio Render CHOP / Steam API

I’m building a spatial audio tool suite. I’m trying to figure out if I should continue building my own delay and volume modeling system, or if the Steam API in the Audio Render CHOP is worth using. Wondering if there’s any documentation on how the Audio Render CHOP works. Which tools it’s actually using from the Steam API, and which variables can be tweaked etc. so that I can evaluate if it’s useful, or if my simple one is already more sophisticated?

The only thing I can find is a snippet and the standard wiki page, which have no real info outside of an overview of how to plug it in.
