An aframe component for adding audio visualizations, using Web Audio. This is an updated version of aframe-audioanalyser-component, with various improvements.
These components mostly provide processed Web Audio data (beat detection, levels, volume, waveform). How that is visualized is up to you (by writing components that use this data to have a visual effect). Components will generally implement the tick handler and read the analyser data. See the examples for some example visualization components.
