At Recall.ai, we built a 10,000-node cluster, processing over 1TB/sec of raw video in real-time. After a major migration, we faced a strange audio issue that led us on a deep dive through our infrastructure. The culprit? Not the audio code—but a hidden interaction with AWS’s virtual serial ports. We wrote about our journey discovering the artifacts and finding a clean fix! |
