Harmonic Exciter Plugins [VST, AU, AAX]DAW music production AAX, AudioUnit and VST exciter plugins that apply a smooth harmonic enhancement, exciter and valve coloration effects to audio tracks. Harmonic enhancement for the sound is like spices for the food, it can be best used to add pleasant grit and subtle brilliance to the sound. Much like with spices, it is possible to overdo the effect, so be careful how much and on what sounds you apply it.
