Technical Insights & Architecture Papers
Deep-dives on high-throughput backend architecture, Python & Django performance, real-time Voice AI, and resilient database modeling.
Opus Codec Optimization for Real-Time Telephony: Forward Error Correction (FEC), Packet Loss Concealment (PLC), and 20ms Frame Sizing
Maximize speech intelligibility and survive up to 30% packet loss in real-time WebRTC and SIP voice AI streams by fine-tuning Opus in-band FEC, DTX, and dynamic bitrate adaptation.
Acoustic Echo Cancellation (AEC) & Full-Duplex Barge-In: Eliminating Self-Interruption in Browser-Based Voice Agents
When voice agents speak through device speakers, acoustic bleed triggers false VAD and self-interruption. Learn how to calibrate AEC3, reference circular buffers, and cross-correlation filters for seamless full-duplex conversations.
