AudioGraphNode.setParams() method
Apply a runtime parameter update to a node in the graph, addressed by the handle returned when it was built (hoist it out of the build closure to keep a reference). An optional PartTransition ramps the change so it is click-free. Only parameters the target op supports take effect (a gain node reads db).
Signature:
setParams(node: AudioNode, update: AudioGraphParamsUpdate): void;
