Liminal Space 2 — Haunted Digital Reverb Synthesizer
A programmable retro reverb synthesizer built around 9,502 algorithms, 22 modulation wavetables, three freely assignable modulation LFOs, True Shimmer, Bloom and real reverse capture, nonlinear decay shaping, and Lexicon 224-inspired filtering and tone controls.
NEWS OCTOBER 26, 2026: Liminal Space 2 RC8 is now available for Windows and macOS. Windows x64 CLAP/VST3 installers, universal macOS CLAP/VST3/AUv2 installers for Apple Silicon and Intel, and the updated RC8 Parameter Guide.
What’s new in RC8
Complete Factory Color calibration: Both platform installers include all 3,965 Color profiles across 19 calibrated banks, including Authentic Soundware, BXI/Bricasti, Midiverb and Korg-based spaces.
Mac compatibility fixes: Repairs the custom editor in REAPER on affected Macs, forwards Space/transport keys in Ableton, and correctly labels the AU format.
Narrow editor layout: Removes the extra gap around the Preset/SORT controls at smaller widths.
The RC7 sound engine, features and saved-sound formats are retained. Existing presets and projects keep their authored settings; manually reselect a Bank and Algorithm to apply its available Color calibration.
Features retained from RC7
GRIT: Tape, Fuzz, Analog Warmth, Speech processing, and more for the input or wet output. Explore tape motion, characterful fuzz, and retro LPC speech textures, with expanded modulation options.
Algorithm Color calibration: More realistic space emulations! Supported algorithms expose Color wet-return EQ and Decay Color damping controls. Selecting a calibrated algorithm applies its fitted Regen; saved presets and projects retain their authored settings.
MATERIAL: Experimental processing modes for spring and plate reverbs.
A larger factory library: 9,502 algorithms across 59 banks, 57 Archetypes, 95 Factory Presets, and 22 modulation wavetables. Many of the latest algorithms include Color calibration. PLUS new reverb algos based on exclusive "space age" impulse responses from our friends at Authentic Soundware!
Refined browsing, controls, and new modulations: Compact single-line readouts, aligned solid slider tracks, clearer contextual help, and stable four-line Preset/Archetype descriptions. Input and output envelope followers enable easy ducked reverb, and input-responsive special effects.
Performance and compatibility: DSP and memory optimizations, shared wavetable storage, and native 64-bit processing support in VST3.
Liminal Space 2 started life as a deeply modified version of Airwindows kCosmos, but quickly grew into its own wildly programmable digital reverb world. Using a custom library of 9,502 reverb algorithms, it delivers everything from intimate 1980s-style rooms to infinite, pitch-warped soundscapes.
At its heart is a 25-tap Householder-matrix delay network, supercharged with features you won’t find in the original:
9,502 Algorithms Across 59 Banks: Explore everything from short, practical rooms to unstable, pitch-warped spaces. The factory collection includes curated banks designed for Liminal Space 2. Algorithm profiles and character/source chips help describe decay, brightness, width, onset, and smoothness. Easily filter by character and length to find the ideal reverb, and use the calibrated "Tail Guide" to dial in approximate decay times.
22 Wavetables from KRC Mathwaves: Drive built-in LFO modulation for “bitcrushed” pitch bending, subtle chorus, or VHS-style wow and flutter. New wavetable modifiers allow for advanced modulation effects.
57 Archetypes, 95 Factory Presets, and User Presets: Start with practical small, medium, and large rooms—or explore gated, modulated, pitch-shifted, lo-fi, atmospheric, and deliberately strange designs. Search Archetypes, Factory/User Presets, and Banks by name and metadata, then use the arrows to audition matching sounds. Edit saved User Preset descriptions and tags without changing the sound.
Deep Modulation: Derez LFO, per-tap delay length DLFO, a modulatable Diffusion Matrix, dedicated Shimmer LFO, and 3 freely assignable Modulation LFOs with expanded pitch, shimmer, diffusion, Vulture Cutoff, and Bloom Amount/Rise Curve/Fall Curve targets for evolving, layered motion and special effects.
Scattering Diffusion: Choose Classic or Scattering in the Diffusion Matrix. Shape density and span, select participating taps, and animate the tail with wavetable-driven Scatter Motion.
Bloom and Real Reverse Capture: Shape fresh excitation with Rounded, Swell, Rise, or Wavetable contours, and shape the audible tail with independent Fall controls. Reverse Capture plays fragments backward with adjustable Length and Overlap; choose Diffuse for a smeared wash or Clear for a more distinct reversed sound feeding the reverb. Dry audio and direct early reflections remain forward.
Vulture 224 Filtering: Lexicon 224-inspired input/output filtering with a continuous Cutoff. Single filters fresh wet input; Double adds output filtering. Sand Reduction remains independent.
Tone Shaping Sections: In addition to an overall FIR lowpass filter, the “LEXITONE” section offers Bass, Mid, Cross, Treble, and HF Spread controls inspired by the Lexicon 224’s characterful decay shaping. Choose Classic or the new Split Decay mode; Regen remains the master decay control while Bass and Mid add frequency-dependent loss. An Output EQ section provides hi/lo shelving and an adjustable mid EQ on the reverb tail.
Pitch-Sweep Path: Apply shimmery or chorus-like motion (or weird pitch bends) directly inside the feedback loop, with phase/depth spread and per-tap targeting. Choose the original Legacy character, the cleaner Legacy Enhanced mode, lush MicroPitch detuning, or the other tank-motion engines. Includes an optimized MicroPitch FFT engine and improved energy regulation.
True Shimmer: Optional pitch-shift shimmer with +/- 24 semitones of shift, detuning, unison, tone control, and a dedicated LFO for unique effects such as vibrato, tremolo, and my unique "field motion" modulation.
Integrated Stereo Widener: Srsly3-style mid/side widening (or focusing!) for the wet signal.
Improved GPU-accelerated GUI: With animated modulation visualization, wavetable phase indicators, and (most importantly) an optional "phosphor glow" effect. The "Easy Panel" makes Regen, Scale, Filter, Mix and Bypass controls easily tweakable throughout the interface. A quick-save diskette handles modified User Presets, with Mix Lock beside MIX. RC6 adds an internal Windows resize grip and scale menu, a dedicated Bloom tab, curve visualizations, and refined library search popups. Regen shows an approximate live RT60 display, NAV jumps directly between major sections, and BYP crossfades to exact dry audio without destroying the running reverb tail.
Gated and Nonlinear Decays: Reshape tails using "Collapse" (Gated), Linear, or "Shadow" contours with adjustable curve behavior. The Collapse envelope can also modulate other parameters, allowing the decay itself to animate pitch, modulation, or wavetable position.
Factory Content Updates: Import official content-update ZIPs from within the plugin when new factory content becomes available, without reinstalling the entire plugin.
Whether you want a subtle glue reverb, a cavernous ambient wash, or an evolving haunted texture, Liminal Space can take you there.

PRAISE FOR LIMINAL SPACE 2
"This thing goes so deep. I've never heard a reverb sound just like this before. It's actually replacing Valhalla for me because you can get in there and go really deep and really creative and create beautiful sounds."
-- Alex Dalliance, @VultureCulture
"How ludicrously powerful Liminal Space 2 is for a reverb. Why isn't this the best selling reverb on the planet? I have no idea. It should be the best selling reverb ever... It's not just a good reverb. It's an outstanding reverb."
-- Doug Woods, @TheSoundTestRoom
