What it does

M-Exciter is Techivation's spectral harmonic exciter. Instead of boosting the treble that is already there, it analyses the audio and generates new overtones on top of it, with the stated aim to "add brightness and presence without harshness."

Excite: sets how much of the generated harmonic content is added, in decibels.
Intensity: controls the density and richness of the harmonics.
Softness: a dynamic suppression threshold that limits the energy of the new harmonics, so loud or sharp passages don't turn harsh.
Harmonics modes: three characters: Warm (the most pronounced), Clear (balanced) and Airy (the subtlest).
Frequency Range: a two-ended slider that sets the band where brightness is added.
Mix Assist: listens to 3.5 seconds of audio and suggests settings as a starting point.
Mix and monitoring: dry/wet Mix for parallel use, Output gain, and a Diff button that plays only the added content.
Workflow: Left-Right or Mid-Side processing, selectable oversampling quality, undo/redo, tooltips and a UI scalable from 80 to 150%.

KVR lists version 1.0.1. A free trial is available.

When to use it

M-Exciter is a top-end tool rather than an all-round drive. Compared with Decapitator or Saturation Knob, which add harmonics and grit across the whole signal, it only adds overtones inside the band you set, so it brightens without thickening or colouring the low mids. It is cleaner and more targeted than RC-20 Retro Color, which is built for vintage character and wear, not polish. Against a plain high-shelf EQ, the difference is that it creates new upper harmonics and tames them dynamically with Softness, so dull sources gain air that an EQ boost can't find. Mix Assist and the three modes make it quick to set, but it has fewer tone-shaping options than a full multi-mode saturator like Saturn 2.

Best for: adding air and presence to dull vocals, acoustic instruments, overheads and full mixes, including at the mastering stage.
Genres: any; most useful on pop, singer-songwriter and acoustic material that needs sparkle.
Look elsewhere if: you want overall warmth, drive or distortion; Decapitator or Saturation Knob fit better, and RC-20 Retro Color suits lo-fi colour.
Tip: use the Diff button to hear only the added harmonics, and raise Softness if that content sounds spiky.
