Oscilloscope Glow
Oscilloscope Glow is a precise audio-analysis display in BeamTracer Audio Visualizers, built on WebGPU. Settings, audio modulation, presets, and tips.
Oscilloscope Glow is a precise audio-analysis display in the Core Analytics category. Open it from the left visualizer list, start an audio source, and use the settings panel to shape its response.
Open Oscilloscope Glow
Launch the visualizer with its matching left-nav entry selected.
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.

How do I share a factory look?
Open SHARE A LOOK, choose a preset from FACTORY LOOK, and select COPY LOOK LINK. The link opens that original preset with its audio reactions. Personal slider edits and music are not included. Use OPEN LOOK to preview what the recipient will see.
How do I share my edited look?
Open SHARE A LOOK, select PREPARE MY LOOK, then choose COPY MY LOOK LINK. The link includes your current visual settings, modulation routes, and generator settings. Music is not included. Use OPEN MY LOOK to preview the result. Prepare a new link after making more edits.
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 |
|---|---|---|
| Glow | Lines | Sets the halo around the lines. Bass pushes it higher by default. |
| Sensitivity | Audio Response | Sets how tall the waveform swings. Mids push it higher by default. |
| Variation Speed | Motion | Sets how fast the lines drift when Line Variation is up. Highs push it faster by default. |
Settings reference
Views
| Setting | Available values | What it changes |
|---|---|---|
| Core | SCOPE, HUE WAVE | SCOPE draws the phosphor trace and its views; HUE WAVE draws a stack of waveform lines in depth, colored by how loud each part of the wave is and by the frequencies under it. |
| View | Classic, Time, Spectrum, Time + Spectrum, Stereo X-Y, Tuned Polar, Delay | Chooses the classic trace, a single view, or time and spectrum side by side. |
| Show Axes | On / Off | Shows time in milliseconds and spectrum frequency in Hz with a fixed dB scale. |
| Align Zero Crossing | On / Off | Aligns the short trace to a rising zero crossing when available. |
| Signal | Mono (Mixed), Left, Right | Displays the mixed signal or one audio channel. |
| Window | 1ms–20ms | Uses the available samples; axes show the actual duration at your sample rate. |
| Tuning | 20Hz–2000Hz | Sets the polar rotation frequency manually; does not detect pitch. |
| Delay | 0.05ms–10ms | Sets the time separation between the two delay-view coordinates. |
Lines
| Setting | Available values | What it changes |
|---|---|---|
| Line Count | 1–500 | Sets how many copies of the waveform are stacked in depth. |
| Line Spacing | 0.001–1 | Sets the gap between stacked lines; wider gaps fan the stack toward and away from you. |
| Glow | 0–3 | Sets the halo around the lines. Bass pushes it higher by default. Use Assign modulation to choose a source. |
Audio Response
| Setting | Available values | What it changes |
|---|---|---|
| Sensitivity | 0–10 | Sets how tall the waveform swings. Mids push it higher by default. Use Assign modulation to choose a source. |
| Depth Movement | 0–2 | Moves each part of the line toward or away from you with the strength of the frequencies under it. |
| Motion Smoothing | 0%–100% | Sets how slowly the lines follow the sound; higher values give a calmer, rounder wave. |
| Frequency Impact | 0%–100% | Sets how much the frequencies under each point lift the wave and shift its color. |
Motion
| Setting | Available values | What it changes |
|---|---|---|
| Line Variation | 0–10 | Lets each stacked line drift and sway on its own path instead of lying on top of the others. |
| Variation Speed | 0–2 | Sets how fast the lines drift when Line Variation is up. Highs push it faster by default. Use Assign modulation to choose a source. |
Core
| Setting | Available values | What it changes |
|---|---|---|
| Amplitude | 0.5–3 | Controls the distance of the motion from its resting position. |
| Time Window | 64 samples–512 samples | Sets how many recent audio samples appear in the trace. |
| Smoothing | 0%–95% | Softens fine detail along the trace. Zero keeps the original detail; higher values draw broader curves. |
| Freeze Trace | On / Off | Turns freeze trace on or off. |
Phosphor
| Setting | Available values | What it changes |
|---|---|---|
| Phosphor Trails | On / Off | Turns phosphor trails on or off. |
| Trail Decay | 70%–98% | Sets how long trail decay remains visible. |
| Trail Thickness | 10%–100% | Sets the visible trail thickness. |
Audio Display
| Setting | Available values | What it changes |
|---|---|---|
| Audio Glow | On / Off | Turns audio glow on or off. |
| Glow Reactivity | 0–2 | Sets the visible strength of glow reactivity. |
| Bass / Mid / High | On / Off | Turns bass / mid / high on or off. |
| Trace Spacing | 0.45–0.75 | Sets the spacing between visible elements. |
Wire Echo
| Setting | Available values | What it changes |
|---|---|---|
| Wire Echo | On / Off | Turns wire echo on or off. |
| Echo Motion | DEPTH FADE, Y FADE, Y SPRING | Chooses the echo motion mode or style. |
| Echo Copies | 1–5 | Sets how many trailing copies of the trace are drawn behind it. Available when Wire Echo is on. |
| Echo Spread | 0.01–0.08 | Controls how far elements separate from the center or from one another. |
| Echo Opacity | 0.05–0.4 | Sets how transparent the echo appears. |
Grid & CRT
| Setting | Available values | What it changes |
|---|---|---|
| CRT Look | On / Off | Turns crt look on or off. |
| Noise Shader | On / Off | Turns noise shader on or off. |
| Show Grid | On / Off | Shows or hides grid. |
| Grid Size | 25px–200px | Sets the visible grid size. |
Material
| Setting | Available values | What it changes |
|---|---|---|
| Line Width | 1–20 | Sets the visible line width. |
| Glow Spread | 0.1–1 | Controls how far elements separate from the center or from one another. |
| Glow Intensity | 0.1–1 | Sets the visible glow intensity. |
| Neon Overdrive | 0.5–2 | Sets how brightly the trace burns; higher values make the line hotter and more vivid, lower values tone it down. |
Colors
| Setting | Available values | What it changes |
|---|---|---|
| Color Mode | GREEN, BLUE, PURPLE, ORANGE, CYAN, WHITE | Chooses the color mode or style. |
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
- Raise Smoothing for broad curves, or lower it to reveal fine waveform detail.
- Use Phosphor Trails or Wire Echo to keep earlier shapes visible as the live trace changes.
- Open Views and choose HUE WAVE under Core for a stack of waveform lines whose color follows how loud each part of the wave is and the frequencies under it. Its Lines, Audio Response and Motion controls appear while it is selected, and the Hue Line, Hue Fan and Hue Sway presets switch to it in one click.
- In HUE WAVE, raise Line Count and Line Spacing to fan the stack in depth, then raise Line Variation to let each line drift on its own path.
