Pop Audio Player is a lightweight ES6 + Three.js (r182) audio player with a GPU-driven visualizer system.
The visualizer is built as a set of GLSL “modes” (fragment shaders) that react to audio analysis (FFT spectrum, peaks, and waveform) and also supports an idle animation path when audio is paused or silent, so the scene doesn’t look dead. Some modes optionally use a ping‑pong feedback/FBO pass to create trails/echo effects.
