Angular CRT
Angular CRT is an expressive audio-reactive composition in BeamTracer Audio Visualizers, built on WebGPU. Settings, audio modulation, presets, and tips.
Angular CRT is an expressive audio-reactive composition in the Creative category. A tilted stack of laser beam-ribbons carries the live waveform, snapping to new angles and mirror figures on every beat while a geometric ring flashes in with expanding echoes — all seen through an analog damage chain of bloom, mirror symmetry, signal warp, RGB fringe, scanlines, and grain. As a track plays, the piece cuts between distinct scene figures: crossing fans, bow-ties, chevron tunnels, cathedral columns, solo shapes, and a smooth morphing interlude.

Scenes and presets
Crossfire is the flagship: full-spectrum laser fans roaming between mirrored scene figures. Neon Flatline, Pulse Cathedral, and Ghost Scan pin a single figure; Ghost Scan also switches the beat language to smooth morphing. Bass Quake and Prism Collapse roam fastest and hit hardest.
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 |
|---|---|---|
| Beam Response | Core | Sets how thick each beam swells as its sound gets louder; higher values make beams fatter and more solid on loud passages. |
| Beam Width | Core | Sets the visible beam width. |
| Beam Halo | Core | Sets how bright the glow surrounding each beam is; 0 leaves only the bare beam. |
| Beat Crumple | Core | Sets how far the beams buckle toward and away from the viewer when a beat hits; 0 keeps them flat. |
| Waveform Drive | Core | Sets how strongly the sound waveform kicks the beams sideways in traveling jolts; 0 keeps them perfectly straight. |
| Bloom Strength | Material | Sets the visible bloom strength. |
| Halo Glow | Material | Sets the visible strength of halo glow. |
| Warp Wave | Material | Sets how much the whole picture ripples with a broad wave after each beat strike; 0 turns the warp off. |
| RGB Fringe | Material | Sets how far the red, green, and blue channels split apart at the edges for a color-fringed screen look; 0 removes the fringing. |
| Scanlines | Material | Sets how dark and visible the horizontal CRT scanlines are; 0 removes them. |
| Grain | Material | Sets how much film-style noise grain is laid over the picture; 0 removes it. |
| Bar Hue Shift | Colors | Moves the color around the color spectrum. |
| Ring Hue Shift | Colors | Moves the color around the color spectrum. |
| Ring Audio Size | Animation | Sets the visible ring audio size. |
| Ring Spin | Animation | Sets the ring spin of the visible composition. |
| Ring Waveform | Animation | Sets how strongly the sound waveform wobbles and distorts the ring; 0 keeps the ring a clean circle. |

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 Beam Response, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
