WHAT IT DOES

Hazex is a lush, atmospheric reverb for electronic music — the kind of space that turns a flat mix into something alive. Dial in anything from a tight, dry room to an endless shimmering cloud, then let the tail move, breathe, and duck around your groove without ever muddying the low end. It's built for producers who want reverb with character and control, not just wet.

Hazex is an algorithmic stereo reverb built on a custom 8-line feedback delay network with a Householder mixing matrix for perfectly even energy distribution. It ranges from tight forensic rooms to massive shimmering halls — with internal sidechain ducking, dynamic saturation, octave shimmer, reverse bloom, and a mono-bass guardrail that keeps club sub systems phase-safe.

FEATURES

Core Engine

Custom 8-line feedback delay network with Householder reflection matrix for perfect energy distribution
Sample-domain prime delay lengths scaled to host rate — eliminates metallic coloring, maximizes echo density
4-point Hermite interpolation on every delay read for smooth, chirp-free high-frequency shimmer
4-stage all-pass input diffuser smears transients into a dense cloud before the tank
Dynamic gain compensation — perceived loudness stays consistent as decay length changes

Tone & Modulation

Size, Decay (0.1–10s RT60), Damping, Pre-Delay, and post-reverb Tone shelf
Vapor stereo decorrelation, Early/late reflection blend, and Haziness (8 independent LFOs)
Spectral Shimmer — +12 semitone pitch shift in the feedback loop for accumulating octave harmonics
Reverse Bloom — grain-based reversal with Hann windowing for a "sucking" tension effect
Tempo-synced Pre-Delay (1/64–1/8) and BPM-synced Swell build macro

Dynamics & Guardrails

Ghost Ducking — internal sidechain with 3ms lookahead so the wet ducks under loud transients
SAT-LINK — input-driven tanh saturation inside the FDN feedback loop, with gain compensation
HPF-LINK — envelope-linked high-pass spectral breathing, up to a 3-octave sweep
Master Link scales SAT-LINK, HPF-LINK and ducking sensitivity together up to 150%
Sub-Anchor — LR4 mono-bass crossover (20–500Hz) protects club sub systems from phase cancellation

Output, Visuals & Presets

Mix, Output trim, true Bypass, and Freeze (infinite sustain) controls

FREQUENTLY ASKED QUESTIONS

Is Hazex free?

Yes. Hazex is completely free to download and use under a proprietary freeware license. No trial, no watermark, no feature limits.

What kind of reverb engine is Hazex?

Hazex is an algorithmic stereo reverb built on a custom 8-line feedback delay network with a Householder mixing matrix and prime-length delay lines. The result is a dense, natural tail that ranges from tight forensic rooms to massive shimmering halls.

What is Ghost Ducking?

Ghost Ducking is an internal sidechain that ducks the wet reverb under loud transients, then lets it bloom back when the input quiets down. A 3ms lookahead lets the envelope see transients before they arrive, so the tail moves with your groove instead of muddying it.

What do Shimmer and Reverse Bloom do?

Shimmer adds a +12 semitone pitch shift inside the feedback loop for accumulating octave harmonics. Reverse Bloom uses grain-based reversal with Hann windowing to create a "sucking" tension effect that pulls the tail backwards.

What is the Sub-Anchor for?

Sub-Anchor is a mono-bass guardrail — an LR4 24dB/oct crossover (20–500Hz) that forces low frequencies to mono. It protects club sub systems from stereo phase cancellation so your low end stays tight and translates on big rigs.

Does Hazex support Apple Silicon?

Yes. Hazex is a Universal Binary that runs natively on Apple Silicon (M1/M2/M3/M4) and Intel Macs.
