Turn one audio track into a self-contained, library-free HTML page that renders an audio-reactive "音波环" (wave ring): 200-ish radial bars arranged in a circle, each pulsing to the track's decoded frequency/amplitude data and looping over the whole song. Use this when a creator has a music file and wants a ready-to-open webpage (no build, no npm, no external library) that visualizes the audio as a rhythmic wave ring — for a personal site hero, a music-video background, or a short-form clip background. Built from JIEJOE's Web-Audio/Canvas tutorial snippet, generalized so a non-coder can go from their own audio file to a working visualizer with chosen colors, bar count, ring size, and pulse speed.
