SEQ-ST is NUGEN Audio's linear phase spline EQ for stereo: instead of bands and knobs, you draw the curve you want directly onto a high-resolution display. It also matches the tonal balance of a reference and morphs smoothly between EQ settings, which makes it as much a creative tool as a corrective one.

Draw it, don't dial it
The resizable direct-draw interface gives you resolution a parametric EQ can't: notch out a cluster of resonances, carve a gentle shelf with a dip in the middle, or shape something that would take eight bands to approximate. Because it's linear phase, there's no phase smearing, so transients stay sharp even after heavy work. Psychoacoustic banding, curve smoothing and node locking keep the curve musical rather than jagged.
Match and morph
Match captures the spectral flavour of a reference track and applies it to yours, handy for mastering against a reference or for making takes recorded on different days sit together. Morph glides between two EQ states, with tempo-locked options for filter sweeps and transitions. Left/right and mid/side channels can be treated independently.
Where it fits
Mastering, bus work and surgical clean-up on vocals and samples. It isn't trying to add analogue character; it's a precise, transparent tool for people who know exactly what they want to change. SEQ-ST is the stereo edition of SEQ-S, which covers surround; the demo below shows SEQ-S, and everything apart from the surround channels applies.
