W43 is a digital noise reduction plugin inspired by a renowned analog system known for its smooth, artifact-free performance. It utilizes four dynamic equalizer engines that selectively increase attenuation in quieter frequency bands while preserving louder sounds, ensuring transparent noise suppression without compromising audio integrity.

This plugin excels at eliminating continuous background noise such as fan hum, lighting buzz, and other low-level ambient sounds often encountered in post-production environments. Unlike broadband noise reduction tools that can introduce unwanted warbling artifacts, W43 delivers clean and natural noise reduction, maintaining the original character of the recording.

Designed for ease of use, W43 offers straightforward controls to set thresholds and adjust noise reduction levels with precision. It supports zero-latency processing, making it ideal for syncing audio perfectly with picture in post-production workflows. This tool is particularly effective for cleaning up location recordings and sound effects, providing efficient noise reduction with minimal effort.
