Noise Filter

A noise filter node reduces unwanted background noise from an audio stream, improving clarity in recordings and live communications. It is especially useful in environments with consistent ambient sounds like hums, hisses, or background chatter. Common features include adjustable noise reduction levels, real-time processing, and optional voice activity detection (VAD) for further enhancement.

The following extensions provide noise filter nodes:
