5 JavaScript Audio Visualizers
Make your music visible with these JavaScript audio visualizers. From bar and waveform animations to immersive 3D experiences, this collection demonstrates how to use the Web Audio API, <canvas>, and libraries like Three.js to create dynamic, real-time visual feedback for sound.
Examples
Glitch Equalizer with Web Audio API and Canvas
This is a powerful demonstration of the Web Audio API and Canvas synchronization, where an AnalyserNode processes real-time audio data to dynamically drive complex visual glitch effects and an animated equalizer display.
See the Pen Glitch Equalizer with Web Audio API and Canvas.
Audio Visualization III using Web Audio API
This audio visualizer leverages the Web Audio API to extract frequency data, driving a real-time, responsive 3D starfield and waveform that reacts intensely to the music’s average volume.
