Hazex Raw
One-Knob Reverb
"Turn it up and the sound drifts back into a lush algorithmic stereo reverb — subtle room early, wide ambient wash at the top, level-matched so it never jumps."
WHAT IT DOES
One knob, from dry to a deep, hazy reverb space. Hazex Raw is the free, one-knob version of Hazex — the algorithmic stereo reverb — giving you a genuinely gorgeous tail with nothing to configure. Drop it on vocals, drums, synths, a pad, or a full bus and open the one knob.
Hazex Raw drops your signal into a lush algorithmic stereo reverb — the same FDN reverb engine from the full Hazex, driven by a single knob. No menus, no setup: drop it on a channel and open SPACE. Size, decay, width and mix all move together, and an output headroom bias keeps the result level-matched so it never jumps forward in the mix. At 0 it's clean and dry.
THE SPACE KNOB
SPACE is a single macro that controls depth. The sweep is front-loaded: early on you get a subtle small room, and as you push it the size grows from room to large hall, the decay stretches musically, the damping softens the tail, and the stereo wash widens. Everything stays balanced and tasteful — and the output bias holds the perceived level steady the whole way.
UNDER THE HOOD
8-line Householder FDN — Hazex Raw runs the full Hazex Pro reverb engine unchanged, a feedback delay network whose eight delay lines use prime-number base lengths for a dense, natural tail free of ringing.
Clean, stable tail — each feedback path has damping, a DC blocker, gentle tanh soft-saturation, and an anti-alias low-pass, fed by a 4-stage allpass input diffuser, so the tail stays clean at every size and decay.
Constant latency — the reverb engine reports zero latency and never changes it mid-stream, so the host's plugin-delay compensation stays stable while you sweep the knob.
One automatable knob — SPACE is the only host-automatable parameter; every hidden engine value is wrapped in a non-automatable subclass so it never clutters the host's automation list, yet all values still save and restore with the session.
Output safety — a soft clipper at 0 dBFS plus a hard limit keep the output bounded, with ScopedNoDenormals and NaN/Inf guards keeping it stable across the full sweep.
