System Audio Visualizer
Capture audio from any screen or tab and transform it into stunning GPU-powered visualizations — all in your browser, no downloads required.
Powerful Features
Everything you need for an immersive audio-visual experience, built with modern web technologies.
Real-Time Audio Capture
Capture audio from any screen, window, or browser tab using the Screen Capture API. No downloads, plugins, or extensions needed.
GPU-Powered Rendering
All visualizations run on the GPU using WebGL and custom GLSL shaders, delivering smooth 60fps performance even with complex effects.
6 Stunning Presets
Choose from six handcrafted visualization presets, each with unique shader effects, particle systems, and audio-reactive behaviors.
Beat Detection
Intelligent beat detection analyzes low-frequency energy peaks in real time, triggering visual bursts synchronized to your music.
Color Themes
Five curated color themes — Cyberpunk, Ocean, Fire, Matrix, and Aurora — transform the mood of every visualization.
Built-In Recording
Record your visualization sessions as WebM videos directly from the browser, ready to share on social media.
Visualization Presets
Six unique GPU-powered visualization styles, each crafted to respond to different aspects of your audio.
Neon Spectrum Bars
Glowing frequency bars that dance across the screen, mapping each audio frequency bin to a vibrant neon column with bloom and glow effects.
Circular Pulse Ring
Concentric rings that expand and contract with bass energy, creating a hypnotic pulsing mandala of light and color.
Particle Galaxy
Thousands of particles swirling in 3D space, their movement and color driven by audio energy to create a living galaxy of sound.
Audio Tunnel
A 3D tunnel that pulses and warps with your music, creating an infinite corridor of reactive geometry and light.
Bass Shockwave
Explosive geometric shapes that detonate on every bass hit, sending shockwaves of light and particles across the screen.
Liquid Shader Field
Fluid shader patterns that morph and flow with audio, creating an organic, ever-changing landscape of color and motion.
Hyper Spectrum
Ultra-responsive frequency bars with 256-bin precision. Mirrored center-out layout, minimal smoothing, and intense neon glow for maximum punch.
Silk Bloom
Delicate silk-like veils and soft blooms that flow and breathe with music. Ethereal, refined, and beautifully subtle.
Edge Flame Convergence
Diagonal flames travel from the four corners toward the center, driven by bass. When all four meet, a shockwave explodes from the center.
Bouncing Person
A flexible articulated figure with cloth-like texture that reacts to audio like a rap, disco, or musician performer. Genre-aware movement with random variation.
Gravity Balls
Balls at the bottom are thrown upward by audio frequency. Gravity pulls them down; they bounce off the floor and the top of the viewport in palette colors.
How It Works
Share Your Screen
Click "Start Visualization" and select a screen or browser tab. Make sure to check "Share audio" in the browser dialog.
Audio Is Analyzed
The Web Audio API captures the audio stream and performs real-time FFT analysis, extracting frequency spectrum, waveform, and beat data.
GPU Renders Visuals
Audio metrics are passed to WebGL shaders that render beautiful, reactive visualizations at 60fps directly on your GPU.
