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 — 30.1 seconds of audio — 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. |
