SEQ-S: Direct-Draw Surround EQ by NUGEN Audio Free Download

SEQ-S uses a direct-draw interface rather than a traditional parametric layout. The developer describes the resolution as finer than what a parametric display allows, and the curve can be scaled, smoothed and locked at specific frequency nodes.

The three independent EQ curves can each be assigned to channels across the surround panorama. Stereo, mid/side, 5.1 and 7.1 operation are all supported, which lets you apply different corrections to left/right and mid/side signals within one plugin instance.

Linear phase spline EQ and a no-phase-smearing design are listed among the features, along with psychoacoustic banding for smoother-sounding changes.

The match EQ function captures the spectral character of a source clip and applies it to your current work. NUGEN Audio points to restoration work and mastering references as typical uses, and to unifying takes or microphone positions on individual tracks.

Inverting the match curve lets you carve space for one element in a dense mix, a more targeted alternative to broad cuts. Match EQ presets are included.

Fluid filter morphing lets the curve move between states over time. The developer highlights tempo-locked effects and scene transitions, with visual feedback as the curve changes.
