New in v0.5.0
Pultec EQ is completely remodeled. The LF section now includes an authentic LCR resonant bump (45% of shelf gain at Q=1.8) that matches the inductor resonance of the original hardware. LF Boost and LF Cut ranges extended to 18 dB. LF Boost Freq now spans 20–300 Hz. New Bandwidth controls on both LF Boost and LF Cut let you dial in shelf width from narrow (Q=1.0) to wide (Q=0.25), making the boost present in the musical 100–300 Hz range.
New: Haas module — psychoacoustic stereo widening via M/S encoding and Haas effect comb filtering. Two modes: Side Comb (mono-compatible) and Wide Comb (diffuse). Hermite-interpolated delay from 1–20 ms with smooth automation and RMS-safe automatic output trim.

Signal Chain
API5500 EQ→ButterComp2→Pultec EQ→Dynamic EQ→Transformer→Haas→Punch
Every module is independently bypassable, fully automatable, and reorderable at runtime via the drag-to-swap UI.
Modules
API5500 EQ
5-band semi-parametric EQ modeled on the API 5500 console equalizer. LF/HF shelves, and three parametric bands (LMF, MF, HMF) ordered low to high.
ButterComp2
Four compression models in one module: Classic Airwindows bipolar glue, VCA (1176-style character), Optical (program-dependent release), and FET (aggressive drive). Built-in NY parallel Mix on every model.
Pultec EQ
EQP-1A style passive equalizer with authentic LCR resonant bump, simultaneous boost/cut, and bandwidth controls. 18 dB range, 20–300 Hz LF coverage, tube saturation.
Dynamic EQ
4-band frequency-dependent dynamics with Compress, Expand, and Gate modes. Real-time spectral analyzer with GR metering. Optional sidechain masking analysis.
Transformer
Vintage/Modern/British/American transformer coloration. Structured INPUT / OUTPUT / TONE sections with independent saturation and frequency shaping at each stage.
Haas
Psychoacoustic stereo widener via M/S encoding and Haas effect comb filtering. Side Comb (mono-compatible) and Wide Comb modes. 1–20 ms Hermite delay, RMS-safe output trim.
Punch
Transparent clipper with Hard/Soft/Cubic modes, up to 8x oversampling, and pre-clip transient shaper for loudness maximization without pumping.
