A lush, atmospheric reverb for electronic music, from tight rooms to endless clouds.
Hazex is a stereo reverb built on an 8-line feedback delay network with prime-length delay lines and Householder feedback mixing. It adds a pitch-shifting shimmer path, input-aware ducking, tempo-syncable pre-delay, and a modulated tail for lush, evolving spaces.

- 8-line feedback delay network with prime-length delay lines and a Householder feedback-mixing matrix for a dense, natural tail.
- Per-line DC blockers keep the feedback path clean and stable.
- Pitch-shifting shimmer feeds an octave-shifted signal back into the network.
- LFO-modulated delay lengths (Haziness) give the tail continuous movement.
- Input-aware ducking with adjustable sensitivity for vocals and busy mixes.
- Tempo-syncable pre-delay for rhythmic placement of the reverb.
- Universal Binary: native on Apple Silicon and Intel.
