SPL Vitalizer Mk3-T, developed by Brainworx, is the definitive plugin version of the famous SPL analog software equalizer, a powerful audio enhancement tool for mixing and mastering engineers that offers a unique approach to improving audio clarity, loudness and bass foundation without introducing harshness.
The Vitalizer Mk3-T is more than just an EQ: it’s a mix finishing tool that gives you intuitive access to cutting-edge, crystal-clear psychoacoustic processing thanks to a patented combination of frequency shaping and bass processing. Always trusted to deliver that last 5% that separates a good mix from a great one, it can play a major role in helping your mixes cut through, sound fuller, and sound more polished. And beyond full mixing and mastering applications, whether it’s sweetening a vocal or tightening up the low end on a drum bus, the Vitalizer Mk3-T is a legendary tool for adding clarity, power, and sonic ‘finish’ to whatever you throw at it.
Cutting-Edge Analog Modeling
Renowned for its almost magical ability to make mixes sound brighter and more detailed (described by engineers and producers as a “voodoo box” for the stereo bus), this latest version of the plug-in represents a major step up from the beloved gold-faced Mk2-T, offering an all-new, precision-engineered Brainworx modeling of the recently improved SPL Studio Series Edition hardware unit with its updated black design, which has been redesigned to operate at a higher internal voltage (±18V) for even more headroom, improved dynamics and enhanced sonic accuracy.
More than just hardware emulation
Vitalizer Mk3-T builds on this core hardware emulation with powerful new features unique to the plug-in, including updated tube modeling, auto bypass, an all-new stereo expander, LC-EQ and a mid/side mode. Perhaps the most important new feature is the Split Bass Mode: this enables the classic Vitalizer magic trick of simultaneously processing both “soft” and “tight” bass characteristics. With these controls, you can perfectly focus and fine-tune the low end on even the most complex and challenging program material, without upsetting the delicate balance of the mix or introducing the side effects typical of more traditional processors.
Scalable and Enhanced Workflow
All of the new additions are seamlessly integrated into an elegant and fully scalable modern interface. The Brainworx top toolbar provides optimal workflow enhancements, including toggles to show/hide the lower control bar for simplified operation and easy switching between the Mk3-T and the included legacy Mk2-T models. That’s right: the Vitalizer Mk3-T includes a “Gold” mode, for maximum color rendition, familiarity, and compatibility options!
Trusted by engineers. Loved by ears.
The original SPL Vitalizer is legendary for a reason. It uses proprietary processing to remove the masking of overlapping frequencies, improving perceived detail and depth by dynamically shifting the timing of loud and quiet frequencies. This means vocals are more expressive, instruments are more clearly separated, and the low end gains both power and weight without being overly boomy.
Why Engineers Love It
- Instantly add detail and dimension by revealing overlapping frequencies
- Tighten and deepen the low end with independent
soft/tight bass processing - Boosts high frequencies and harmonics without harshness
- Increases perceived loudness and clarity without raising peak levels
- Makes tracks feel more “finished” with just a few simple controls
