Multiband Destruction Engine
Break the spectrum. Control the collapse.
Four bands. Twenty distortion types. Shape your sound with Event Horizon, link controls with Orbit Link, protect the low end with Mass Lock and morph between four Collapse States. Try the real engine on your own samples in the live browser demo.
Concept interface. Final product may differ.
01 / Engine
A kick does not need the same destruction in its sub, body, attack and air. QUASSAR turns the spectrum into four deliberate processing zones, then gives you one gravitational field to move them together.
Each band has its own algorithm, drive, bias, tone, mix and output. Fold the highs while the lows stay warm.
The foundation is a separate zone with its own rules, so aggression above never has to cost you weight below.
Set your own Event Horizon routes and response curves, then move them together with one performance control.
02 / Crossover
Drag the crossover points to redraw where each engine takes over. The visualisation is illustrative and does not process your audio.
Use the arrow keys to move a crossover point. Home and End jump to its limits.
20 Hz – 110 Hz
Weight, pressure, ground.
110 Hz – 550 Hz
Mass, density, impact.
550 Hz – 3.0 kHz
Edge, presence, teeth.
3.0 kHz – 20 kHz
Fizz, noise, digital detail.
03 / Bands
Every band can use any of the twenty distortion types, with its own drive, bias, tone, mix, output, solo and mute. Three adjustable crossovers define the split. The four diagrams below are illustrations; hear the actual processing in the live demo.
Foundation
Keep the weight intact, saturate it with control, or turn it into tectonic pressure without sacrificing the rest of the spectrum.
Punch
Shape the frequencies that carry mass and impact. Add density, carve movement, or make every transient hit harder.
Aggression
Fold, clip and fracture the frequencies that make a sound cut through a mix.
Texture
Push the upper spectrum into fizz, noise, digital edge and unstable detail.
04 / Event Horizon
Route one macro to Drive, Bias, Tone, Mix and Output in each band. Set an endpoint and a Linear, Ease In, Ease Out or Smooth curve for each route, then scale the movement per band. At 0%, your base sound stays intact.
Upper bands fold and fracture. The air turns to texture while the sub is held in place by the patch.
Drag the orb or use the arrow keys. Shift changes the step size.
Diagram only. Shows how one patch could distribute pressure across the four bands.
05 / Signature features
All four signature features are implemented and available in the live demo. Open the Macros page inside QUASSAR to configure the routes, links, protection and snapshots.
One macro. The whole spectrum moves.
Twenty configurable routes across four bands. Choose endpoints, response curves and band amounts, then perform them with one macro. Your route settings travel with the preset.
Destroy the spectrum without surrendering the foundation.
Blend processed low frequencies back toward their aligned clean reference. Adjustable protection follows the SUB / BODY crossover and also reduces low frequencies generated by distortion in the upper bands.
Move linked bands while preserving the relationships that made the patch work.
Assign bands to group A or B and link Drive, Bias, Tone, Mix or Output. A knob move shifts the linked group while preserving relative offsets, stopping together at the first control limit.
Travel between processing states instead of switching abruptly between them.
Capture four named sound configurations, choose any two endpoints and morph between them. Snapshots include algorithms, crossovers, quality and all three other signature features. Recall an endpoint or return to the base sound.
Start with 14 factory presets, including drum, bass, vocal and texture starting points. Search by name, distortion type or signature feature, bookmark favorites and save up to 32 user sounds.
Keep separate A/B comparison states, copy between them and undo or redo sound edits. Export and import portable JSON presets, including macro routes and Collapse snapshots.
Choose 1×, 2×, 4× processing. All quality modes keep a fixed 96-sample effect latency; browser and audio-device buffering add their own playback delay.
Follow the live input spectrum and input/output meters, with per-band scopes and native response previews that follow your settings. Monitor output peaks and reset clip indicators.
The Windows VST3 build exposes 63 product controls plus host bypass, with parameter gestures and project-state recall. Public release and manual DAW acceptance are still in progress.
Upload a local WAV, trigger it from the start and change the distortion while it plays. Loop, pause and stop playback, with a separate listening-volume control after the effect.
06 / Algorithms
Every type below runs in the real QUASSAR processing core and is selectable in every band. Start with saturation, clipping and folding, or explore rectification, digital reduction, signal memory and chaos.
Four illustrative examples. Hover or focus to increase their drive; use the live demo to hear the actual engine.
Smoothly rounds peaks for gentle saturation and increasing density.
A rounded polynomial curve that reaches firm saturation at its limits.
Asymmetric saturation with different positive and negative headroom.
Emphasises larger waveform excursions with a signed square-law curve.
Cuts peaks at fixed limits for a direct, sharp clipping character.
Clips the positive and negative halves at different thresholds.
Suppresses the centre of the waveform before driving larger excursions into clipping.
Reflects peaks back into range, adding folds as the drive increases.
Bends the signal through repeating sine-shaped folds.
Keeps the positive half of the waveform and removes the negative half.
Flips the negative half upward for full-wave rectification.
Reduces amplitude resolution from 16 toward 2 bits as drive increases.
Holds samples for longer intervals to produce stepped digital texture.
Switches between two output levels when the signal crosses opposing thresholds.
Limits how quickly the waveform can change, softening fast edges.
Builds a leaky, bounded signal history into the current output.
Holds the output until the input moves far enough to cross a change threshold.
Varies the saturation drive over time for moving, unstable texture.
Adds signal-dependent noise and clipping for a rough surface.
Feeds a resonant signal history into saturation for ringing, rebounding colour.
07 / Sound
Load a local WAV in the live demo, choose a preset and trigger it through QUASSAR. Adjust the controls while it plays, loop the sample or compare the effect with bypass.
Your sample. The real QUASSAR engine.
The browser demo is ready to play. Choose Upload sample, then Trigger sample. WAV files stay on your device and playback starts only when you ask. Prerecorded examples are still being prepared.

QUASSAR is built for material where distortion needs to be specific rather than general.
Fold the mids into a harder attack while the sub stays clean and centred.
Add growl and edge in the body and bite while the fundamental keeps its weight.
Turn clean hits into metallic, unstable texture without turning the low end to mush.
Give the bite band the aggression that cuts through, with the air controlled separately.
Roughen presence and air for character while the body stays intelligible.
Apply different destruction to each region of a full mix instead of one blanket saturation.
09 / Formats
The VST3, Windows desktop build and browser demo use the same C++ processing core and portable sound format. The web demo is live; native builds are implemented and undergoing release validation.
Windows VST3 build with host automation and project recall. Release and DAW qualification are in progress.
Windows desktop build with local WAV playback through the native engine. Public release is pending.
Live browser preview with local WAV upload and the same C++ processing core.
Current native builds target Windows x64. Signing, final installer qualification and manual DAW acceptance remain open. The browser demo runs over HTTPS in browsers with AudioWorklet and WebAssembly support.
