Plasma Disk is a responsive simulated scene in the Simulation category. Open it from the left visualizer list, start an audio source, and use the settings panel to shape its response.

Launch the visualizer with its matching left-nav entry selected.

Quick start

  1. Start the demo track, choose a local audio file, or enable a live input.
  2. Try a preset or style first, then open the section for the part of the image you want to change.
  3. On a control with Assign modulation, open the source picker, choose a signal, and watch the slider's live fill.
  4. Use Reset to Defaults whenever you want to return to the original look.

Audio modulation

On a control with Assign modulation, select the activity icon to open Modulate with. Choose a named source, or choose — None to leave the control unmodulated. After you assign one, its name appears below the slider; select that name to edit the route, or use Clear modulation to remove it. The slider track shows the live signal reaching the control.

Modulated controlSectionWhat the route changes
Arc BranchingDischargeSets how many side branches split off the main arcs, so higher values give a denser, more tree-like discharge and 0 leaves only the main arcs.
Line WidthDischargeSets the visible line width.
Gas GlowDischargeSets the visible strength of gas glow.
Tip SparkleDischargeAbove 0.5, makes the tips of the arcs flash and sparkle with the high frequencies, so higher values give brighter twinkling at the ends.
Arc RippleAudioSets how far the live waveform bends each arc. An assigned source scales that bend from the displayed base.
Orbit SpeedGlass & RoomSets how quickly orbit changes or moves.

Disc

SettingAvailable valuesWhat it changes
ModeFLAT DISC, GLASS DISC, DEPTH / ORBITChooses the active mode or style.
Gas / PhosphorALCOVE GREEN, XENON BLUE, ARGON VIOLET, NEON EMBER, MAGENTA, WHITE, TRICOLORChooses the gas / phosphor mode or style.
Diameter0.5–0.98Sets how large the disc is on screen, from about half the view up to nearly filling it.
Core Ratio0.025–0.16Sets the size of the bright central core relative to the disc, so higher values give a larger core and push the start of the arcs outward.
Electrode Glow0–2Sets the visible strength of electrode glow.
Edge GlowOn / OffTurns edge glow on or off.
Streamer Reach0.45–1Sets how far the arcs stretch from the core toward the edge of the disc; bass hits extend them slightly further.
Arc Count8–24Sets how many visible elements are drawn.
Path Detail12–48Sets how finely each arc path is divided, so higher values give more intricate, detailed zigzags and lower values give simpler, smoother bends.
Follow MouseOn / OffTurns follow mouse on or off.
Auto TouchOn / OffTurns auto touch on or off.

Discharge

SettingAvailable valuesWhat it changes
Drift Speed0.05–2Sets how quickly drift changes or moves.
Wander0–1Sets how much the arcs drift and wobble sideways on their own, so higher values give restless, wandering arcs and 0 keeps them steady.
Smoothness0–1Sets how smooth the arcs are, so higher values give gentle, flowing curves and lower values make them jitter and crackle.
Arc Branching0–1Sets how many side branches split off the main arcs, so higher values give a denser, more tree-like discharge and 0 leaves only the main arcs. Use Assign modulation to choose a source.
Branch Energy0.15–1Sets how much energy the arcs carry out into their branches, so higher values give stronger, longer-reaching arcs and lower values make them fainter.
Line Width0.004–0.065Sets the visible line width. Use Assign modulation to choose a source.
Glow0–1.5Sets the visible strength of glow.
Phosphor MemoryOn / OffTurns phosphor memory on or off.
Strike CracksOn / OffTurns strike cracks on or off.
Gas Glow0–1Sets the visible strength of gas glow. Use Assign modulation to choose a source.
Tip Sparkle0–1.5Above 0.5, makes the tips of the arcs flash and sparkle with the high frequencies, so higher values give brighter twinkling at the ends. Use Assign modulation to choose a source.

Bloom

SettingAvailable valuesWhat it changes
Strength0–2Sets the visible strength of strength.
Radius0–1Sets the visible radius.
Threshold0–1Sets the level that must be crossed before threshold appears.

Audio

SettingAvailable valuesWhat it changes
Audio ReactivityOn / OffTurns audio reactivity on or off.
Master Gain0–3Sets how strongly the input signal affects master.
Bass0–3Sets how strongly bass drives the arcs, widening them and extending their reach on kick hits, so higher values give bigger reactions to low notes.
Mids0–3Sets how strongly mid-range sound drives the arcs, so higher values make them move faster and more energetically with vocals and instruments.
Highs0–3Sets how strongly high frequencies drive the arcs, so higher values bring out more fine detail and sparkle on cymbals and hi-hats.
Level0–3Sets how strongly overall loudness drives the glow of the disc, so higher values make the light swell more with the music.
Smoothing0.01–0.8Balances immediate audio response against steadier motion.
Bass Arc Count0–12Sets how many visible elements are drawn.
Bass Width0–2Sets the visible bass width.
Mid Motion0–3Sets how quickly mid motion changes or moves.
High Filigree0–2Sets how much fine, lacy detail high frequencies add to the outer ends of the arcs, so higher values give more delicate squiggles on bright sounds.
Waveform Bend0–0.7Sets how much the live sound waveform bends the arcs sideways, so higher values make the arcs ripple with the shape of the audio.
Arc Ripple0–1Sets how far the live waveform bends each arc. An assigned source scales that bend from the displayed base. Use Assign modulation to choose a source.
Note Hold0–1Sets how long note hold remains visible.

Glass & Room

SettingAvailable valuesWhat it changes
Transmission0–1Sets how much light appears to pass through the material.
Glass Thickness0.05–1Sets the visible glass thickness.
Glass Roughness0–0.6Moves the surface from polished toward matte.
Dispersion0–1Sets how much the glass splits light into colored fringes, so higher values add a rainbow edge to the glass and its caustic light; available in Glass Disc mode.
Caustic Energy0–1.5Sets how bright the colored caustic light patterns inside the glass are, so higher values give stronger glowing patterns that react to the music; available in Glass Disc mode.
Caustic Occlusion0–20Sets how much the colored caustic light fades toward the curved edges of the glass, so higher values keep it concentrated in the middle of the face; available in Glass Disc mode.
Room Light0–1.5Sets how bright the surrounding room light and its reflections on the glass are, so higher values light the glass more; available in Glass Disc mode.
Orbit Amount0–0.8Sets how strongly the camera orbits the disc.
Orbit Speed0–0.8Sets how quickly orbit changes or moves. Use Assign modulation to choose a source.
Disc Tilt-45°–45°Sets the disc tilt of the visible composition.

Some controls appear only after you enable a related mode or style. The settings panel always reflects the options available for the current selection.

Tips for a better audio visualization

  • Start with moderate audio strength. Large gain changes can overwhelm the motion before you can see what each band contributes.
  • Try assigning Bass to Arc Branching, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
