LIMINAL
NEGATIVE-SPACE EFFECT
by Ament Audio · v0.0.1 · AU · VST3 · Standalone
LIMINAL is a threshold-based atmosphere engine that lives in the silence between your notes. While you play, it listens. The moment your signal drops below the threshold, it opens — conjuring reverb, shimmer, and pitch ghosts shaped around what you just played.
The dry signal always passes through unaffected. The haunt, shimmer, and ghost are inaudible while you play — they only exist in the negative space.
WHAT IT DOES
THRESHOLD DETECTION
An envelope follower watches your signal and opens the engine when you stop playing. Fully adjustable sensitivity — from 'any pause' to 'only true silence'.
HAUNT REVERB
A reverb engine that exists only in the negative space. It shapes itself around what you just played and dissolves before the next note begins.
SHIMMER
Pitch-shifted shimmer conjured from the ghost of your signal. Crystalline, sustained, and inaudible while you play.
PITCH GHOST
Captures your pitch and reintroduces it as a faint, drifting echo in the silence — like an impression of the note left in the room.
SLEW CONTROL
Sets how fast the atmosphere fades in and out at the threshold boundary. Fast slew = abrupt conjuring. Slow slew = breath-like crossfade.
RAMP A/B MORPH
Store two complete parameter states (A and B) and morph between them. Trigger manually or let the threshold crossing drive the transition automatically.
TONE
Spectral tilt applied to the conjured material. Negative = dark and woolen. Positive = bright and crystalline. Stacks with Shimmer for extreme textures.
MOD MATRIX
Route the envelope follower, LFO, or ramp position to any parameter — let the plugin's own detection drive depth, mix, or ghosting amount.
STARTING POINTS
After the chord fades
Threshold 60% · Haunt high · Crystallize medium · Slew slow
Set a slow slew so the reverb blooms in gently after each chord release — inaudible on top of your playing.
Pitch tail
Possession high · Drift Rate low · Threshold 50%
Captures your root note and reintroduces it as a barely-there tail. Works well on sustained melodic lines.
Crystal void
Crystallize high · Tone +0.5 · Threshold 30% · Slew fast
Triggers on any brief pause. Fast slew means the shimmer snaps in immediately — ghostly and unsettling.
Ramp A/B sweep
Snapshot A: dry haunt · Snapshot B: full crystallize · Ramp: auto
Set A as a subtle state and B as extreme. Let threshold crossings drive the morph — each phrase triggers a transformation.
