Mandelbrot
Mandelbrot is an expressive audio-reactive composition in BeamTracer Audio Visualizers, built on WebGPU. Settings, audio modulation, presets, and tips.
Mandelbrot is an expressive audio-reactive composition in the Creative category. Open it from the left visualizer list, start an audio source, and use the settings panel to shape its response.
Open Mandelbrot
Launch the visualizer with its matching left-nav entry selected.
Mandelbrot opens on Seahorse Filigree: crisp teal spirals from the seahorse valley with warm accents, breathing slowly; the bass breathes the view, each beat ripples the accents and the highs sparkle along the filaments. Pick FILIGREE among the coloring styles under Material to draw any Julia set this way, and try the Seahorse Overview and Sin Storm presets.
Wings
Pick WINGS in the mode buttons under Core for a mirrored pair of wings with glowing eyespots, a body and fine veins. The bass beats and opens the wings, the mids let their shape drift, each beat steps the colors on, and the highs add lace and shimmer along the veins.
- Flap sets how far the wings beat; Open sets how far they spread.
- Fold picks the mirror: Sides for one pair, Lake for an upper and lower pair, Quad for four and Diagonal for eight. Fold Angle tilts the fold to grow the body and veins.
- Detail adds finer lace, Palette and Palette Speed choose and cycle the colors, and AA smooths edges.
- Try the Amber Eyes, Moonlit Moth, Peacock and Lacewing presets.
CANOPY, beside it in the mode buttons, grows glowing branching trees around the center whose arms curl to the music, the trunks with the bass and the tips with the highs, and sprout new branches on loud passages and beats.
Quick start
- Start the demo track, choose a local audio file, or enable a live input.
- Try a preset or style first, then open the section for the part of the image you want to change.
- On a control with Assign modulation, open the source picker, choose a signal, and watch the slider's live fill.
- 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 control | Section | What the route changes |
|---|---|---|
| Flap | Wing Shape | Sets how far the wings beat; the chosen audio band drives the beat, and a slow beat continues in silence. |
| Open | Wing Shape | Sets how far the wings spread, from tight lace to wide open; the chosen audio band opens them further. |
| Fold Angle | Wing Shape | Tilts the fold at every step, which grows a body and veins between the wings; the chosen audio band tilts it further. |
| Detail | Wing Shape | Sets how many folding steps build the wings; more steps add finer lace. The chosen audio band adds steps on loud moments. |
| Palette Speed | Wing Color | Sets how fast the colors cycle across the wings; each beat also steps the palette forward. |
| Branch Angle | Tree Shape | Sets the angle between each branch and the branch it grows from; the chosen audio band opens it further. |
| Spread | Tree Shape | Sets how large each branch is beside the one it grows from, so the tree spreads wider or stays compact; the chosen audio band makes it breathe. |
| Sway | Tree Shape | Sets how far the left and right branches sway apart and together; a slow sway continues in silence and the mids swing it. |
| Curl | Tree Motion | Sets how much the arms curl at rest, more at every split, like fern tendrils; the chosen audio band curls them further. |
| Curl Music | Tree Motion | Sets how much the music curls the arms: the bass curls the trunks and the highs curl the tips. |
| Flow | Tree Motion | Sets how far behind the outer branches follow the music, so each curl travels out along the arms; zero moves the whole tree together. |
| Growth | Tree Motion | Sets how many branches the music grows: loud passages and beats sprout new splits up to DEPTH, and they fade back in quiet ones. |
| Speed | Tree Motion | Sets how fast the trees turn around the center; negative values turn them the other way. |
| Glow | Tree Color | Sets how far the glow spreads around the branches; the chosen audio band brightens it. |
| Trap Glow | Filigree | Sets how strongly the warm accents glow where the orbit traps light up; each beat ripples them, and the chosen audio band brightens them. |
| Zoom Mod | Shape Response | Sets the visual zoom mod. |
| Iterations Mod | Shape Response | Trades visual detail against performance. |
| Julia Real Mod | Shape Response | Sets the horizontal value of the Julia constant that determines the fractal shape; the chosen audio band makes it wobble around this value. |
| Julia Imag Mod | Shape Response | Sets the vertical value of the Julia constant that determines the fractal shape; the chosen audio band makes it wobble around this value. |
| Hue Offset Mod | Appearance Response | Sets the base hue rotation of the fractal colors in degrees; the chosen audio band pushes the hue further on loud moments. |
| Distance Glow Mod | Appearance Response | Sets the spacing between visible elements. |
| Stripe Density Mod | Appearance Response | Controls how concentrated the visible elements appear. |
| Trap Mix Mod | Appearance Response | Sets how much the orbit-trap pattern is blended into the fractal coloring, from 0 for smooth bands to 1 for pure trap pattern; the chosen audio band increases the blend. Takes effect when the coloring style is ORBIT. |

Tips for a better audio visualization
- Assign different bands to structure, motion, and light instead of routing every control to Volume.
- Try assigning Bass to Flap, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
