NLS from Waves is a modeling plug-in that brings the warm sounds of three, vintage console summing busses, to a DAW. It allows for adding depth, crunch, analog noise, and harmonic distortion to individual tracks, busses, or both. Modeled consoles include an SSL 4000G, EMI TG12345 Mk 4, and a customized 60/92 Neve 5116.

Over thirty channels on each console, plus their master busses were sampled, and different modeled channels can be selected on each of the three consoles, creating a non-linear summing system. Non-linear summing is the natural effect of an analog environment, offering a larger sound, more headroom, and a wider stereo image.
