Great filter!

It would be great to add layer rotation!)
For doing anything other than basic scaling with sound you can check out Exeldro's Move Transition plugin, it includes an Audio Move filter that can change pretty much everything
I really like this plugin, but when I turn the filter off, the text object that was bumpin is a different size, a little smaller or whole bunch bigger and have to zoom way out of the canvas to sometimes find the object. I end up deleting and bringin up another.
What's the issue and how can I keep the same scale, the lock. Or is it possible my audio gate could have something to do with it?
Definitely a bug, I'll try to fix it soon. Are there any other filters on the plugin? Do you click the eye in the filters list or does another plugin turn it off? What OS are you on?
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
