 "title": "Switching transports beats buffering harder by 27-97x in peak buffer, and the whole benefit is in what you no longer have to hold",
 "symptom": "A fixed-transport relay with a large buffer and a transport-switching relay both delivered every sample with zero loss across an identical 150-second disturbance schedule. They are not equivalent. The fixed relay needed 964,544 bytes of buffer \u2014 30.1 seconds of audio \u2014 to keep that promise. The switchers needed 9,968 to 36,288 bytes. Last-sample end-to-end delay was 11,689 ms fixed against 11 to 43 ms switched.",
