01 / 04 CALM by Everworks / Fluge

A processor for CALM on stage.

Intelligent live audio processor that suppresses feedback, resonance, noise and bleed — while preserving the natural tone and dynamics of the source. Sub-bass optimisation chain. Aligns, tightens and contours the low end so kicks, toms and bass guitars share the room — without fighting it. Zero-latency intelligent livebus processor for master, matrix, stream and PA buses. ATLAS adds weight, punch, air and depth while GUARD keeps translation, low-end and peak safety under control. Musical algorithmic reverb with a 16-line HyperFDN core, 4D tail modulation, spectral EDR fog and subtle glue so vocals, drums and synths bloom without washing away the source.

/ 01Overview

Built for the people.

CALM listens to the room in real time. It identifies feedback before it rings, attenuates resonances surgically, and rejects bleed — all without colouring the source. MAGNETAR BETA is a master-insert sub enhancer for techno and electronic shows: more sub information, more impact and controlled finishing without broad level hype. ATLAS LiveBus is a zero-latency intelligent bus processor for live masters, matrices, streams and PA outputs. It adds psychoacoustic weight, punch, air and depth with live-safe guard rails and per-module bypass. STARDUST is the third Everworks suite plugin: a musical algorithmic reverb built around a 16-line HyperFDN, tesseract-style delay motion and dynamic Householder feedback.

  • b.Bleed-aware gate keeps the timbre, drops the spill.
  • c.Per-mic profiles. Saved with the show, not the laptop.
  • a.SUBSTANCE fills the sub band without turning the whole master into a louder file.
  • b.IMPACT adds front-edge weight for kicks and bass drops in techno systems.
  • c.FINISH and GLOW are gain-conscious: polish, air and presence with beta-safe headroom.
  • a.WOW, WEIGHT, PUNCH, AIR and DEPTH move the mix psychoacoustically, not as blunt EQ boosts.

/ 02How it works

Three stages. One signal path.

01 Listen

Continuous spectral profile Multiband sub analysis Psychoacoustic bus read Energy decay relief

A 4096-point FFT runs alongside the source. CALM identifies build-up before the ear does. MAGNETAR splits the master around the sub band and tracks low-end energy before adding anything, so the enhancement starts from the mix instead of a fixed tone. ATLAS follows crest, loudness, transient density and broad spectral balance so the macros react like a live engineer touching the bus. STARDUST reads the wet tail as a frequency-time field, so the visual fog follows the decay instead of decorating it.

02 Decide

Surgical, not broad Coherence first Enhance under guard Dense, not metallic

Up to 32 adaptive notches with Q ≥ 64. Wide enough to control, narrow enough to disappear. SUBSTANCE adds controlled sub support, IMPACT shapes punch, GLOW opens the top aura and FINISH glues the master with beta-safe headroom. WOW glues, WEIGHT anchors, PUNCH restores front edge, AIR opens presence, DEPTH widens perceived space, and GUARD keeps the bus inside live limits. Prime delay spacing, all-pass delay drift and a 4D-modulated Householder matrix build density while avoiding obvious ringing.

03 Deliver

Transparent output Translatable low end Direct live output Glue behind the source

The source still sounds like itself. CALM targets the unstable energy instead of rolling off the whole channel. The output is gain-conscious for master bus use: more weight and presence, without pretending a fader lift is processing. The path is direct and zero-latency: no lookahead master limiter, no offline-style latency, just controllable live enhancement with Dry/Wet and instant bypass. Per-line damping, wet ducking and subtle saturation let the HyperFDN bloom musically without masking vocals or leads.

/ 03Features

Six tools for a quieter mix. Four macros plus beta-safe presets. Seven live controls for a bigger, safer bus. Six tools for a 4D musical space.

f.01

Adaptive notch engine SUBSTANCE WOW 16-line HyperFDN engine

32 simultaneous notches that move with the source — never a static EQ. Low extension and sub fill tuned for techno masters and large PA sub arrays. Psychoacoustic cohesion that makes a live mix feel more finished without needing master-bus latency. A 16-line feedback tank uses prime spacing, all-pass delay drift and dynamic Householder mixing to build density without metallic repeats.

f.02

Feedback predictor IMPACT WEIGHT Spectral EDR fog

Neural de-reverb designed to reduce room tail while preserving direct voice. Transient weight for kick authority and drops, shaped to avoid broad master gain jumps. Low-gravity bus support for PA and stream feeds, tuned to feel solid before it feels louder. The analyzer draws the wet decay as a moving frequency cloud, making tail energy readable at a glance.

f.03

Bleed reduction FINISH PUNCH Early reflections

Stage spill suppression optimized for headset, lavalier and backline isolation. Master polish and glue inspired by high-end limiter workflows. Powerful by design; conservative by default. Transient focus for drums, playback and full-band buses, with safety compensation built around live gain staging. Deterministic stereo taps define depth in the first milliseconds while preserving the dry front edge.

f.04

Tone preservation GLOW AIR Damping and diffusion

Spectral-aware processing that keeps formants intact even at high reduction. Champagne air for presence and openness after the low-end work, without turning the plugin into a bright EQ. High-band clarity and expensive shine shaped for live systems, not a static top-end shelf. Per-line feedback absorption lets high frequencies die naturally before the body of the tail.

f.05

Live low-latency mode Factory presets DEPTH Glue and ducking

Choose 21 ms precision when selectivity matters or Zero Latency when monitoring and live response come first. Clean Master, Master Safe, Techno Weight, KS28 Sub Fill, Kick Authority, Air Glue and Festival Check. Perceived dimension and width enhancement for buses that need depth without reverb smear or added latency. Subtle saturation and envelope-aware wet ducking keep the reverb expensive, present and out of the way.

f.06

Vocal Chain Beta build package GUARD + Dry/Wet Five musical modes

Unified secondary finishing deck featuring Expanse, Clean EQ, DNS, and Glue bus compression. macOS AU/VST3/Standalone and Windows VST3/Standalone beta builds packaged for quick installer-free testing. Live-safe macro with global blend and per-module bypass, so engineers can add only the lift the show can take. Chamber, Plate, Hall, Nimbus and Infinity cover tight vocals, lush plates and cinematic tails.

/ 07FAQ

Things engineers ask.

Does it colour the source?

No. CALM uses spectral-aware processing that targets only the offending energy. At high reduction levels you may notice the room calming down — never the source. MAGNETAR is designed to keep the master musical. SUBSTANCE and IMPACT should feel bigger before they feel louder; FINISH is intentionally powerful and best used conservatively in the beta. ATLAS is intentionally audible when you push it, but it is built for live translation: the macros add perceived finish while GUARD, Dry/Wet and per-module bypass keep the bus under control. It is designed to add space without stealing the dry source. Damping, ducking and glue keep the tail behind the vocal or lead.

Can I run it on in-ear monitor mixes?

Yes. Use Zero Latency for monitoring-sensitive routing, or Studio 21 ms when maximum selectivity is more important than latency.

Will it work on broadcast and corporate gigs?

Yes. CALM is designed for corporate, broadcast and live workflows where lectern mics, lavs and stage microphones need stability without obvious processing.

How is it licensed?

Yes. Register free to unlock the download. No payment, no subscription, no watermark.

How can I help improve it?

Run it on real shows, tell us what works, report edge cases and suggest new modules. That is the exchange: free access for useful real-world feedback.
