Discussion / Feature request: inspecting audio nodes

[anvlkv]

I'm working on a crate insta-fun - snapshot testing for fundsp AudioUnits.

In the project where I use it some audio nodes are getting quite complex with bus/pipe/stack etc. For that matter I wanted to add graphviz dot snapshots. I've implemented that for traversing the net: nodes and sources. However the output of .display() isn't too informative and there no way I can "look" into the node to see the actual wiring there.

I'm curious, if you think something could be done to "unerase" the audio nodes types, so that I can build more detailed graph, or if its not worth the efforts.

Thanks!

Hi, that's a nice project.

I think it can be done. It requires 3 new AudioNode methods. Here's how I've sketched it out:
-input_source: retrieves recursively the input source for a node input.
-output_source: retrieves recursively the output source for a node output.
-fill_inner: fills in inner data about a node.

All 3 methods can use a default implementation for leaf nodes, so it's not a humongous effort. Nodes in the object tree are identified by their path from root. The path can also be used to identify children, siblings and so forth. The type of a node is its associated constant ID, which is unique.

If you would be open to introduce those to fundsp, I'd be happy to work on a PR.

That's okay, I can do the implementation. I'll update this issue when it's ready.

Hi!

Any update on this, anything to try out, or any help wanted?
