AudioNode_2 type

An opaque handle to a node in an AudioGraphBuilder. The only way to obtain one is to create a node, and every operation requires handles for its inputs — so the graph you build is acyclic by construction: you cannot reference a node that doesn’t exist yet (no cycles), nor name one that was never created (no dangling refs). Reuse a handle to fan it out.

Signature:

export type AudioNode = {
    readonly __audioGraphNode: unique symbol;
};
