Voxengo Peakbuster

Peakbuster, an attack-phase boosting and harmonic enhancement plug-in for professional music and sound production applications, available in AAX, AudioUnit, VST, and VST3 plug-in formats, for macOS and Windows computers.

Peakbuster is a multi-band transient enhancer effect plug-in that uses an advanced automatic algorithm.

Peakbuster stands out from the competition in its ability to always sound natural, even on a full-spectrum master bus. The strength of the effect depends on the material being processed: the algorithm masterfully analyses dynamics of the sound it processes, and applies boosting in quantities that are "exactly right". Moreover, the algorithm has a suitably “fast” reaction time making its adjustments sound “fluid”, not "over the place".

The amount of effect can be chosen independently for the lower and higher frequency ranges: this permits use of Peakbuster on a variety of program material, both full mixes and individual tracks.

Additionally, due to the nature of the algorithm’s design, Peakbuster applies a unique harmonic coloration or enhancement: so, even if the gain adjustment meter shows only a minimal transient boosting amount at a given time, the plug-in still transforms the sound being processed in a way that to some engineers may sound "on a completely another level"; Voxengo would call it "beyond tube warmness".
