What is Grain Discharge?
It is a granular effect plugin where a fluid simulation drives when and how grains are spawned from recent input audio.

What it is
Grain Discharge is a granular effect where grains are driven by a fluid simulation instead of a static trigger model. Incoming audio excites the simulation, cavitation events appear, and those events spawn grains from a rolling history of your source signal.
Because the simulation is the event driver, it shapes timing, impact, movement, and character of the grain cloud. The same loop does not repeat in exactly the same micro-pattern every pass, so you get recurring identity without rigid repetition. You can steer behavior with Burst, Density, Friction, Speed, Size, Fade In, Linger, and pitch-family controls, while the visual field stays tightly linked to what the engine is actually doing.
At lower Linger and moderate Burst, it can do reactive rhythmic sprays and articulated textures. Push Density and Linger with softer Fade In, and it shifts into smeared grain clouds and reverb-like atmospheres. It also works beautifully as a motion layer before downstream effects when you want controlled unpredictability that still feels musical.

Highlights
Cavitation-driven grain spawning
Fluid simulation events trigger grains from recent input history instead of fixed static timing.
Behavior-shaping controls
Burst, Density, Friction, Speed, Size, Fade In, and Linger let you steer rhythm, turbulence, and texture thickness.
Pitch-family particle system
Per-grain pitch families and modulation add harmonic color and movement inside the cloud.
How producers use it
- Reactive rhythmic grain sprays from drums and percussion loops
- Smeared, cloud-like atmospheres from sustained synth or guitar input
- Reverb-adjacent texture layers with more motion and edge
- Creative transitions where controlled instability feels musical, not random
Fit and focus
Great fit for:
- granular effects with movement and personality
- science-inspired DSP concepts
- playable unpredictability in production workflows
Probably not for:
- fully deterministic grain repetition every pass
- transparent utility-only processing
- ultra-light CPU tools for large tracking sessions
Questions people ask
How is it different from typical granular plugins?
Instead of fixed grain timing engines, it uses cavitation-event behavior as the trigger system, so the response stays input-reactive and alive without exact repetition.
Who is it for?
Producers and sound designers who want granular texture that feels musical, animated, and steerable in real sessions.
What does it do to sound?
It can move from tight reactive sprays to dense drifting grain clouds, with enough structure to stay connected to the source signal.
Compatibility
macOS 10.15+
AU, VST3
