NFuse: Dual-Module Bus Processor Plugin by Kiive Audio

Each module offers its own saturation voicing. One is a crisp, harmonic saturation with Drive and Density controls that change how the saturation responds to the signal. The other is a rounded, thicker saturation with a Dark setting that adds weight to the low end and a Red setting that enhances the top-end harmonics.

The compression options differ as well. One module uses a bus compressor with a reputation for punch and glue, while the other uses an optical compressor with adjustable recovery speed and a Hi-Ratio mode for heavier compression. Both modules include a two-band EQ, with one described as mastering grade for adding low-end weight and presence and air, and the other a two-band shelf EQ for smooth tonal shaping.

The stereo width controls let you widen or narrow a track or the full mix. The developer describes the stereo widener as spatial and true to sound, and suggests it for a wider drum room or an enhanced mix bus. A high-pass filter in the stereo section keeps the low end intact while widening.

The input section includes a variable high-pass filter that sets where processing begins. On one module this filter includes a small resonance bump. The output section provides level controls, global bypass and metering.
