Harrison Mastering EQ

What Harrison Mastering EQ Is For

Harrison Mastering EQ is a software equalizer dedicated to the critical stages of mastering and finalizing, when every half-decibel counts. It is used to balance a full mix without altering its character: opening up the high end, reinforcing the low end, taming harshness in the midrange, or even evening out the perception of a track across different playback systems. Its design emphasizes transparency and musicality, ideal for engineers who want to make "significant" corrections while preserving the original mix's identity.

Main Features

31 bands for truly surgical mastering equalization

The core of Harrison Mastering EQ is based on 31 equalization bands spread across the entire audible spectrum. Each band can be boosted or cut by up to 14 dB, allowing both subtle corrections and more pronounced interventions when the program demands it. The goal is not to "transform" a mix, but to refine it with a level of adjustment finesse that respects harmonic balance and overall coherence.

A filter shape designed to avoid the pitfalls of classic equalizers

Where many equalizers can generate unwanted interactions between bands (peaks, dips, a sense of coloration or imbalance), this plugin's design aims for a smoother response. Thanks to its DSP curve matching technology, adjustments made on adjacent bands tend toward a "flat-top," resulting in more natural transitions. The outcome: you sculpt the spectrum without creating artificial contours, an essential point in mastering where the goal is to enhance rather than reinvent.

High-pass and low-pass filters: clean shaping without harshness

Harrison's high-pass and low-pass filters are designed to refine a master elegantly. They allow the removal of unnecessary low-end rumble (rumble, vibrations, unwanted sub energy) or to control excess highs (hiss, sibilance, harshness), while maintaining a natural feel. Available slopes facilitate discreet cleaning, perfectly suited to a modern mastering chain.

Built-in RTA analysis: quick decisions, ear + visual feedback

To work quickly and accurately, the equalizer integrates two complementary RTA modes. The "Graph" mode offers precise reading with a resolution of 1/10 octave, particularly useful in low frequencies to spot excesses, resonances, or imbalances between fundamentals. The "Lightning" mode provides a more dynamic visualization, highlighting average levels and transient peaks: handy for controlling impact, brightness, and spectral stability during final adjustments.
