Finally can write this audio visualizer toolkit the way I wanted to. I wanted to do it like

type Node struct {
    Start() // Does any necessary startup tasks, mostly launching a
            // goroutine to handle input and output in the background.
}

// Outputs information
type Source struct {
    Node
    ConnectOutput(Sink) // Connects this source's output to a Sink's input
}

// Consumes information
type Sink struct {
    Node
    ConnectInput(Source) // Connect this sink's input to a Source's output
}

// Consumes and outputs information.
type Pipe struct {
    Node
    Source
    Sink
}

Before, I can't remember what I had to do to work around it, but I ended up just giving up on the project. Sounds like it'll be time to pick it back up soon.
