Here's what they say:
FireCharger analyses your audio material and gets it as close as possible to what our sound engineers consider ideal. The result is richer and more balanced sound of any track.
FireCharger does it with touching just a few knobs. In most cases, you can just load a FireCharger preset and simply dial the Dry/Wet knob.
In addition, FireCharger offers advanced vintage tube tape-machine saturation simulation which can give your sound some additional warmth and live feel. And to make your tracks shine, we added a special sophisticated height dynamic exciter.
Price: €129. But you may grab the intro price which gives you €110 off (€19) off until December 6th, 2020.
A 15-days fully working trial version will give you the full experience.
