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.

Capture audio from any screen, window, or browser tab using the Screen Capture API. No downloads, plugins, or extensions needed.

All visualizations run on the GPU using WebGL and custom GLSL shaders, delivering smooth 60fps performance even with complex effects.

Choose from six handcrafted visualization presets, each with unique shader effects, particle systems, and audio-reactive behaviors.

Intelligent beat detection analyzes low-frequency energy peaks in real time, triggering visual bursts synchronized to your music.

Five curated color themes — Cyberpunk, Ocean, Fire, Matrix, and Aurora — transform the mood of every visualization.

Record your visualization sessions as WebM videos directly from the browser, ready to share on social media.

Six unique GPU-powered visualization styles, each crafted to respond to different aspects of your audio.

Glowing frequency bars that dance across the screen, mapping each audio frequency bin to a vibrant neon column with bloom and glow effects.

Concentric rings that expand and contract with bass energy, creating a hypnotic pulsing mandala of light and color.

Thousands of particles swirling in 3D space, their movement and color driven by audio energy to create a living galaxy of sound.

A 3D tunnel that pulses and warps with your music, creating an infinite corridor of reactive geometry and light.

Explosive geometric shapes that detonate on every bass hit, sending shockwaves of light and particles across the screen.

Fluid shader patterns that morph and flow with audio, creating an organic, ever-changing landscape of color and motion.

Ultra-responsive frequency bars with 256-bin precision. Mirrored center-out layout, minimal smoothing, and intense neon glow for maximum punch.

Delicate silk-like veils and soft blooms that flow and breathe with music. Ethereal, refined, and beautifully subtle.

Diagonal flames travel from the four corners toward the center, driven by bass. When all four meet, a shockwave explodes from the center.

Click "Start Visualization" and select a screen or browser tab. Make sure to check "Share audio" in the browser dialog.

The Web Audio API captures the audio stream and performs real-time FFT analysis, extracting frequency spectrum, waveform, and beat data.

Audio metrics are passed to WebGL shaders that render beautiful, reactive visualizations at 60fps directly on your GPU.

No sign-up, no downloads. Just click and start visualizing.
