wave animation library / visual wave effect tool

wavesurfer.js is an interactive audio waveform visualizer that renders real-time wave effects from audio data onto canvas, so it fits the wave animation library category, but its focus on audio peaks means it lacks the water ripple simulation, multiple wave layers, and CSS-only options this search asks for.
