Not the author, but I'll give my take on this. The Soundpipe library underlying Sporth is ideally suited to doing exactly what you describe. It exports all the required functions in a way that can be easily integrated with any extensible language. So if you want to make a library-for-X version of this, everything is set up for you. Sporth can basically be considered a minimal demonstration of this ability. This minimalism is also one of Sporth's strengths - it made it very easy to port to WebAssembly, for example. Also consider that Sporth is almost like a markup language for audio graphs, where each occurrence of a verb represents a node in the graph. The graph is then initialized and run with minimal overhead over all samples. It's certainly possible to reproduce this in a library, but I suspect it limits your options in terms of target languages.
