The Waves W43 Noise Reduction Plugin was developed to bring the trusted, musical qualities of classic analog noise reduction hardware into modern post-production workflows. In film, broadcast, and video production, location audio often suffers from ambient noises like hum, traffic, and HVAC systems, which can muddy dialog and distract from the narrative. W43 was created to address these issues without introducing common digital artifacts such as phase warbling or pumping. By emulating a revered analog noise reduction unit and using a four-band dynamic EQ system, W43 delivers artifact-free dialog clarity while preserving the natural character of the original audio. It was specifically engineered to meet the real-time demands of editors and sound engineers working in fast-paced or less-than-ideal recording environments.
