Noise suppression isolates the speaker and strips out everything else in real time. AI models like RNNoise and DeepFilterNet do this far better than old filters, and products either self-host them or buy a service such as Krisp.

AI for Video: A Complete Guide to Intelligence in Video Products: From Real-Time Pipelines and Agents to Serving, Cost, Compliance, and Verticals
Noise suppression has to clean speech within a few milliseconds per frame, or it adds the delay it was meant to hide. This volume covers noise suppression in real-time calls: RNNoise, DeepFilterNet and Krisp, where AI plugs into a WebRTC pipeline, call latency budgets, and cost per stream-hour. Written by Nikolay Sapunov, CEO at Fora Soft.
