The W43 Noise Reduction Plug-In from Waves is inspired by and built on the legacy of the renowned CAT 43 processor. Ambient noise such as hiss, hum, traffic, wind and air conditioning noise can all wreak havoc on film/video production dialog tracks. With four, fixed frequency bands, the plug-in is easy-to-use for post production environments. It delivers high-quality noise reduction with minimal artifacts (like the original hardware), while providing the advantages of software, such as multiple simultaneous instances.
