AudioLoudness
Make things react to sound. Turn a track's loudness into a number and wire it into a glow, a size or a light's brightness.
An AudioLoudness node measures what reaches its Audio input: Level is the RMS loudness in dB or linear (Mode), smoothed by Attack and Release in milliseconds and updated every frame. Wire Level into any number input; audio becomes a number only through this node. Add it in the Nodes window from Add > Audio > Loudness; its card shows a level bar.
