TransGainer, an audio AU and VST plugin suitable for a wide range of professional music production uses, implements an audio signal envelope adjustment algorithm that reacts on transients rather than on a signal’s loudness level. This algorithm allows you to adjust volume of attack and sustain stages of any sounds you use it on.
TransGainer was designed in a way to be suitable for all possible sound sources – be it individual tracks or full mixes.
