Features
Everything Audio Reactive Background & Pattern Generator can do.
Audio reactivity
Every effect — including the pattern generator presets — pulses, warps, and shifts in real time with the bass, mid, and treble of your track. Map each frequency band to any parameter for a look that moves with the music.
Pattern generator built-in
Use the dedicated pattern generator category to make seamless, tileable geometric patterns — Checker Pulse, Hex Grid, Topo Contours, Wave Lines and more — with live scale, density and color controls for wallpapers and social backgrounds.
50+ generative effects
Shaders, particles, gradients, pattern generator patterns, and abstract visuals — 50 ready-to-use backgrounds and patterns, each fully customizable and audio reactive.
Full timeline editor
Sequence multiple background and pattern generator clips, set per-clip duration, duplicate, delete, scrub, and loop to build a longer composition.
Per-effect properties
Tune colors, speed, intensity, scale, count, and more with live sliders and color pickers, plus one-tap color presets — including for every pattern generator preset.
Social-media presets
One-click canvas sizes for YouTube (16:9, Full HD, 4K, Shorts), TikTok (9:16), Instagram, Twitter, Facebook, LinkedIn, and Pinterest — ideal for pattern generator exports as wallpapers or vertical stories.
Save & restore projects
Save your pattern generator and background composition to the browser, download it as a project file, and load it back anytime to keep editing.
Export to video & image
Render your pattern generator and background to MP4 (H.264), WebM (VP9/VP8), or a still PNG/JPG (perfect for seamless pattern tiles) at 480p–1080p and 24/30/60 FPS, with an optional audio track.
Live preview & zoom
Watch the pattern generator and animation react in real time and zoom the canvas in or out from the center before you export.

How to use
A quick walkthrough, step by step.
Load your audio
Open the pattern generator and background tool and load an audio track, or use the built-in sample.
The live meter shows the bass, mid, and treble in real time as the track plays.
Pick your canvas size
Choose a social-media preset — YouTube, TikTok, Instagram, and more — or a custom size for your pattern generator tile.
The canvas updates instantly to the correct aspect ratio (16:9, 9:16, 1:1 square for seamless patterns, and more).
Add background & pattern generator clips
Browse the effects by category: shader, particle, gradient, pattern generator, or abstract.
Click any pattern generator effect (Checker Pulse, Hex Grid, Wave Lines) or background to add it as a clip on the timeline.
Add as many pattern generator and background clips as you like to build a longer composition.
Customize each clip
Select a clip to open its properties — especially for pattern generator presets tune scale, density, colors and speed.
Map the bass, mid, and treble to any parameter so the pattern generator and background react to the music.
Edit the timeline
Set each clip’s duration, duplicate a clip, or delete one.
Scrub, play, and loop to preview the full pattern generator sequence before exporting.
Save or export your pattern
Save the pattern generator project to your browser or download it as a file to restore later.
Export your pattern generator result to MP4, WebM, or a still PNG/JPG tile at your chosen resolution and frame rate, with optional audio — great for seamless wallpapers.
Frequently asked questions
Everything you need to know about Audio Reactive Background & Pattern Generator.
What is an audio reactive background and pattern generator?
It is a single tool that is both an audio reactive background maker and a pattern generator. Backgrounds pulse, warp, and shift in real time with the bass, mid, and treble of your audio track, while the pattern generator creates seamless geometric patterns (Checker Pulse, Hex Grid, Wave Lines etc.) that also react to music.
Can I use it as a pattern generator for wallpapers and social posts?
Yes. The Pattern category is a full pattern generator with 10 seamless presets — Checker Pulse, Chevron Flow, Diamond Lattice, Dot Matrix, Animated Grid, Hex Grid, Moiré Interference, Topo Contours, Tri Mesh and Wave Lines — each with scale, density and color controls for wallpapers, textile repeats and social backgrounds. Export a still PNG/JPG tile for a seamless wallpaper or an animated pattern video for stories.
Can I use it for YouTube and TikTok?
Yes. There are one-click canvas presets for YouTube (16:9 HD, Full HD, 4K, and 9:16 Shorts), TikTok (9:16), Instagram, Twitter, Facebook, LinkedIn, and Pinterest, so your pattern generator and animated background fits the platform exactly.
How many background and pattern generator effects are there?
There are 50 built-in effects across five categories: shader (Aurora, Nebula, Plasma, Holographic, and more), particle (Starfield, Fireworks, Fireflies, Snowfall), gradient (Mesh Gradient, Spectrum Bars, Hue Wheel), pattern generator (10 patterns: Checker Pulse, Hex Grid, Topo Contours, Wave Lines, Moiré etc.), and abstract (Kaleidoscope, Metaballs, Tunnel, Fluid Flow).
Is there a timeline editor for patterns?
Yes. You can sequence multiple pattern generator and background clips, set each clip’s duration, duplicate or delete clips, scrub through the timeline, and loop the playback to build a longer pattern animation.
Can I customize each pattern generator effect?
Yes. Every pattern generator effect has its own properties — colors, speed, intensity, scale, density, count, and more — with live sliders and color pickers, plus one-tap color presets.
How does the audio reactivity work for patterns?
Each pattern generator and background clip can map the bass, mid, and treble frequency bands to any of its parameters. For example, you can drive the pattern density with the bass and the pattern speed with the treble, so the pattern responds to the music in real time.
What formats can I export my pattern to?
You can export your pattern generator result as video MP4 (H.264 + AAC) or WebM (VP9 or VP8 + Opus), or as a still seamless tile PNG or JPG. Choose 480p, 720p, or 1080p and 24, 30, or 60 FPS, with an optional audio track — perfect for looping wallpapers.
Can I save my pattern generator project?
Yes. Save the pattern generator composition to your browser, download it as a project file, and load it back later to keep editing.
Is it free and private as a pattern generator?
Yes. This pattern generator is completely free and runs entirely in your browser — your audio, patterns and project never leave your device, and there is no sign-up or watermark.
Do I need to install anything to use the pattern generator?
No. The pattern generator is a web app that runs in any modern browser. Video export uses the WebCodecs API, so MP4 and WebM are written directly with no transcoding.
