Waves NS1 Noise Suppressor is a noise suppression plugin designed to give the advantage to the voice when the signal is contaminated by unwanted noise. It is used to reduce background hiss, ventilation noise, room noise, slight hum, or an overly present ambiance, in order to achieve a clearer and closer voice. In the studio as well as in audio editing, NS1 integrates perfectly into a simple processing chain: quick cleaning before compression and equalization, or correction at the end of the chain to salvage a take that would otherwise be difficult to use.
The strength of NS1 lies in its "one knob" philosophy: you raise the fader until the background noise recedes, without dealing with complex settings. This approach is ideal when you need to process many files, work under time constraints, or stay focused on performance and editing rather than technical details.
The plugin relies on real-time audio analysis to distinguish voice from noise. The goal is to reduce disturbances while preserving a natural and usable voice, with immediate results during listening. This responsiveness makes it a valuable ally for video post-production, podcasts, voice-over, and more broadly, any situation where message clarity is paramount.
A meter instantly displays the amount of noise reduction in progress. This provides a clear reference to dose the processing and avoid overdoing it, especially on takes that are already fragile or highly dynamic.
