Super simple and lots of fun. I'm using it for my Halloween stream to make dancing skeletons get bigger and smaller with my voice. If I were to change anything I would give the ability to respond to ALL audio sources, desktop and mic.
Great result for music vizualization. Even better when also used with the spectralizer plugin. Only wished there was a MacOS version of it.
This works INCREDIBLY well. Used it to make my logo bump to the music while on the Starting Soon screen.
One note for dev: Add ability to scale over 100%, and add volume ceiling (audio DB level for highest zoom)
Does exactly what it advertises, makes for a super simple way to get some nice looking audio feedback icons! :D
