RNNoise removes steady background noise from speech with a very small neural network, so it fits client-side and on weak hardware. It is a popular free starting point for call denoising, though heavier models can sound cleaner.

AI for Video: A Complete Guide to Intelligence in Video Products: From Real-Time Pipelines and Agents to Serving, Cost, Compliance, and Verticals
RNNoise is light enough to run in a browser, which makes it the default first try for call noise suppression, but it struggles with non-stationary noise. Volume 7 covers RNNoise in detail within real-time AI for calls: the call latency budget, where processing sits in the WebRTC pipeline, client versus server inference and cost. Written by Nikolay Sapunov, CEO at Fora Soft.
