Complete low-end control.

• GROUNDWORK — mastering-grade head-bump saturation, gain-normalized within ±0.35dB so warmth never masquerades as loudness
• DE-MUD — a three-band dynamic notch with double-precision filtering, dissolving mud automatically instead of carving a static EQ cut
• WALL OF BASS — provably mono-safe stereo field on the 40–60Hz band, real low-end width that never costs you translation

Transparent glue compression.

• UNDERTOW — three mastering-grade compressor characters, VCA, opto, or vari-mu, with zero added distortion in any mode
• BALLISTICS — attack and release track your material's own crest factor in real time, so the glue never fights the mix
• DETECTOR — Lean tilts the sidechain's ear toward lows or highs, shaping the glue without ever coloring the signal path

Mid-range harmonic control.

• HARMONIC CHARACTER — blend warm even-order harmonics against gritty odd-order, measured flat so it's tone, never a volume trick
• TUBE DRIVE — a mid-band saturation engine recalibrated 10x hotter, unconditionally bounded so it never spikes or clips unexpectedly
• FOCUS — sweep a log-mapped 400Hz–4kHz band with a live Hz readout, targeting exactly where a mix turns boxy

Mastering-grade enhancer behind four knobs.

• AIR STAGE — three cascaded Baxandall shelves (700Hz, 10kHz, 16kHz) through harmonic saturation, with RMS gain compensation so more air never means more loudness fooling your ears
• TO THE STARS — a parallel enhancer that adds sparkle, centered in the image
• SPARK HAPPY — puts real energy back into transients up top

Source-matched space and depth.

• REVERB ENGINE — an 8-line lossless Householder FDN built for mastering depth, not a wash — dense, natural, never smeared
• BIT-EXACT BYPASS — verified 0 differing samples at rest; the wet signal is purely additive, so your master never gets colored by accident
• TRANSIENT DUCKING — the tail ducks up to 10dB under transients and recovers in ~300ms, so attacks stay punchy instead of smearing into the space

Precision mastering loudness.

• TAPE STAGE — independent Low/Mid/High drive into a true three-band harmonic matrix, true-bypass at 0% so color is always a choice, never a tax
• LOUDNESS ENGINE — a wideband limiter with blended fast/slow release, built to hit competitive loudness without ever sounding pumped
• SMOOTH HAPPY — presence taming linked directly to gain reduction, tamed exactly when the limiter's working hardest, gone completely at rest

The complete metering suite.

• LOUDNESS — true BS.1770-5 loudness metering, not an approximation
• GATING — real two-stage gating, the same math a broadcast meter uses
• REAL WORLD MATRIX — hear it the way a phone, earbuds, or streaming actually will

All 8 core plugins, one window.

• ARCHITECTURE — every module is the real plugin's own code, compiled directly in, not a clone
• SIGNAL CHAIN — drag any module to reorder the chain, hear it differently in seconds
• MIXING — per-module wet/dry blending, dial in exactly how much of each stage you want
