About this plugin
NUGEN Audio's SEQ-ST is a linear phase parametric EQ that replaces the traditional node-and-slider interface with direct-draw curve editing, allowing real-time manipulation of frequency response across the entire spectrum. Rather than working with fixed Q values and isolated bands, users draw custom curves point-by-point, with the plugin calculating frequency node positions and bandwidth automatically through psychoacoustic banding algorithms.
The technical implementation prioritizes phase coherence, employing spline curve scaling and smoothing to eliminate phase distortion while maintaining surgical precision. A zoomable interface accommodates both broad tonal shaping and microscopic surgical work without compromising workflow. The plugin operates in true stereo, mid-side, or independent left-right modes within a single instance, making it exceptionally efficient for corrective work that would otherwise require parallel processing chains.

Where SEQ-ST distinguishes itself is in specialized matching functions. The EQ matching feature allows users to capture the frequency response characteristics of a reference source and apply those qualities to target material, useful for cohesive vocal blending or matching microphone positions across multiple takes. The inverted matching mode serves a counterintuitive but powerful purpose: subtracting a reference curve reveals carving opportunities in dense mixes without the heavyhandedness of traditional EQ.
This tool appeals to mastering engineers requiring transparent, phase-accurate EQ work and post-production professionals managing dialogue placement in complex soundtracks. The direct-draw paradigm also suits producers comfortable with visual curve editing, though the learning curve exceeds standard parametric interfaces. Among similar offerings, SEQ-ST's combination of matching functions and mid-side capability positions it as a specialist tool rather than a universal alternative to traditional parametric EQs.
