The W43 Noise Reduction Plugin Black Friday deal brings 79% off this Waves audio restoration tool, which lands it at $29.99 until Nov 26, 2026.
W43 is built to push continuous background noise down without the warbly artifacts that broadband noise reduction can leave behind.
Four dynamic EQ engines sit behind it. Each one increases attenuation in its band as the signal gets quieter, so louder sounds pass through untouched.
The maker says it is tuned for steady, low-level ambient noise like fans and lighting.
According to the developer, W43 models a widely used hardware unit that relies on analog noise reduction, a design noted for gentle, clean and efficient results.
Editing is two steps. Set the threshold, then pull down the slider or sliders for the bands you want to reduce.
On Mac, W43 supports macOS Monterey 12, Ventura 13, Sonoma 14 and Sequoia 15, in VST, AU and AAX formats.
On PC, it needs Windows 10 or later and comes as VST and AAX.
