Background Liquid
Background Liquid is an ambient full-canvas background in BeamTracer Audio Visualizers, built on WebGL. Settings, audio modulation, presets, and tips.
Background Liquid is an ambient full-canvas background in the Backgrounds category. Open it from the left visualizer list, start an audio source, and use the settings panel to shape its response.
Open Background Liquid
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.
Presets and styles
Midnight · Lava · Aurora · Mercury · Deep Sea · Psychedelic
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 |
|---|---|---|
| Scale | Core | Sets the visual scale. |
| Pattern Z | Core | Sets how many folds appear in the second, finer set of horizontal ripples of the liquid; higher values make tighter, busier swirls. |
| Flow X | Animation | Sets how strongly the liquid is dragged along its first swirl layer; negative values drag it the opposite way and 0 removes the effect. |
| Flow Y | Animation | Sets how strongly the liquid is dragged along its second swirl layer; negative values drag it the opposite way and 0 removes the effect. |
| Speed | Animation | Sets how quickly speed changes or moves. |
Settings reference
Core
| Setting | Available values | What it changes |
|---|---|---|
| Scale | 0.1–4 | Sets the visual scale. Use Assign modulation to choose a source. |
| Pattern X | 1–15 | Sets how many folds appear in the first set of horizontal ripples of the liquid; higher values make tighter, busier swirls. |
| Pattern Y | 1–15 | Sets how many folds appear in the first set of vertical ripples of the liquid; higher values make tighter, busier swirls. |
| Pattern Z | 1–15 | Sets how many folds appear in the second, finer set of horizontal ripples of the liquid; higher values make tighter, busier swirls. Use Assign modulation to choose a source. |
| Pattern W | 1–15 | Sets how many folds appear in the second, finer set of vertical ripples of the liquid; higher values make tighter, busier swirls. |
Colors
| Setting | Available values | What it changes |
|---|---|---|
| Background Opacity | 0–1 | Fades the liquid field itself so your own footage or backdrop shows through; at 0 the canvas is fully transparent. |
| Color 1 | Color | Sets the color 1. |
| Auto Hue 1 | On / Off | Turns auto hue 1 on or off. |
| Hue Speed 1 | 0.1–10 | Sets how quickly hue 1 changes or moves. |
| Color 2 | Color | Sets the color 2. |
| Auto Hue 2 | On / Off | Turns auto hue 2 on or off. |
| Hue Speed 2 | 0.1–10 | Sets how quickly hue 2 changes or moves. |
| Color 3 | Color | Sets the color 3. |
| Auto Hue 3 | On / Off | Turns auto hue 3 on or off. |
| Hue Speed 3 | 0.1–10 | Sets how quickly hue 3 changes or moves. |
| Color 4 | Color | Sets the color 4. |
| Auto Hue 4 | On / Off | Turns auto hue 4 on or off. |
| Hue Speed 4 | 0.1–10 | Sets how quickly hue 4 changes or moves. |
Audio
| Setting | Available values | What it changes |
|---|---|---|
| Master Gain | 0x–3x | Sets how strongly the input signal affects master. |
| Smoothing | 0–0.99 | Balances immediate audio response against steadier motion. |
Animation
| Setting | Available values | What it changes |
|---|---|---|
| Flow X | -1–1 | Sets how strongly the liquid is dragged along its first swirl layer; negative values drag it the opposite way and 0 removes the effect. Use Assign modulation to choose a source. |
| Flow Y | -1–1 | Sets how strongly the liquid is dragged along its second swirl layer; negative values drag it the opposite way and 0 removes the effect. Use Assign modulation to choose a source. |
| Speed | 0.1–3 | Sets how quickly speed changes or moves. Use Assign modulation to choose a source. |
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
- Use lower modulation amounts than you would for a foreground effect so the background supports the mix instead of competing with it.
- Try assigning Bass to Scale, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
