Abstract
Recording a real-time engine's output without dropouts or clipping: capture on a dedicated audio-thread node (an AudioWorklet) so main-thread stalls can't starve it; tap after the final limiter so the file can never clip; route the capture node to an always-silent (zero-gain) sink so the graph pulls samples through the tap inaudibly; and flush the node's tail buffer on stop before encoding, with graceful fallback to a ScriptProcessor using the same encoder.
