Wanted to recreate the effect of some very bright led lights flashing on sound.

Here is a video preview on Facebook :

This will analyse the ambient loudness and smooth the sensitivity of the audio input over some seconds to allow the composition to look nice (lights not to be too small or too big) and analyse the frequencies wether the ambient volume is high or low. May be better methods to do so, any other method welcome.

You can adjust the sensitive (max lights size) and time of ambient loudness analyse & smoothness on the 2 magenta tinted nodes (MaxLightSize & Duration of the smooth Node).

One the startup as it analyzes the loudness, the lights take 3-5 seconds to grow to ambient volume so watch them grow.

Public Domain, of course I always appreciate a credit / link if used.
