United Plugins FireMaster
Mastering Plugin
Your mix is already great but you still feel it needs a little extra polish. A gentle push to perfectness. That so-called cherry on top is FireSonic's FireMaster. This ultimate mastering finisher will give your mix more body, air, and perfect balance.
Give Your Track the Final Touch
FireMaster is meant to be inserted on your master track to give your mix the final polish. It is the extra push that will make your song sound stronger than your competitors.
The Body and Color
The core sophisticated algorithm is divided between two controls. Depth and Color controls are responsible for the psychoacoustic feel of great space and a strong body.
Manage Highs and Lows
Don't reach for external EQs. FireMaster has precisely tuned controls for mastering bass and treble. It will give your tracks perfect bottoms and a great amount of fresh Air.
Maximal Ease of Use
The simplicity of use is based on the number of presets. You may choose one that fits your needs and just by driving the Wet/Dry control you add the desired amount of perfectness.
CPU-Friendly
Even though the contemporary computers' performance almost reaches the sky there's always a need to administer it wisely. Although FireMaster is meant mainly for master tracks the unit is highly optimized for use on multiple tracks without draining too much CPU power.
Be Creative
The name FireMaster suggest the plugin is made for mastering only. But the truth is it can be used with great results on vocals, bass or drums. Creativity knows no limits.
Hassle-Free Software Protection
No iLok, no dongle nor internet access is required for activation. Our software uses license files to activate your software. You can freely use the purchased software on all your computers as long as you are the user.
Realistic 3D Yet Flexible GUI
The photorealistic graphic user interface of the plugin gives you the feeling you are touching the real hardware. But it easily adapts to your needs. You can always drag the arrow in the bottom right corner to change its size - make it smaller to save the valuable screen space, or enlarge it to make it easier to use.
