01Overview

SEQ-ST is built around a direct-draw interface, so you sculpt the frequency curve by drawing and resizing it rather than adjusting fixed parametric bands. The plugin uses linear-phase spline EQ, which the developer says avoids phase smearing. Its match feature can capture the spectral character of a reference track and apply it to your mix, and an inverted match curve can carve space for one element inside a busy arrangement. Stereo and mid/side processing are available, including independent left/right and mid/side operation within the same instance.

Direct-Draw EQ Curves and Sculpting Control

The interface is zoomable and resizable, and you can draw curves directly. NUGEN Audio says this gives finer resolution than a traditional parametric interface, which makes small, precise corrections easier to place.

Curve scaling and smoothing help you refine a shape after drawing it, and frequency node locking keeps a chosen point fixed while you adjust the rest. Psychoacoustic banding is also included, along with tempo-locked effects for creative movement in the curve.

Because the EQ is linear phase, the developer notes that it avoids phase smearing during processing.

EQ Matching for Mixing and Mastering

EQ matching captures the tonal character of a source audio file and applies it to your current work. This is useful as a reference when mastering, or for unifying different takes and microphone positions on individual tracks.

The match curve can also be inverted. NUGEN Audio describes this as a way to carve space for one element in a complex mix with a less invasive approach than a conventional EQ cut.

Match EQ presets are included for recalling settings quickly.
