Hi, I’m an author of blender add-on “AudVis”. Its basic goal is to make it easier to create animations responsive to sound, including real-time sound analyzing.
It is available in Blender Market and Gumroad, but if you send me a message, I will send you a free copy. It works best with Blender 2.80. Now it works with Blender 2.81 alpha, but no in-depth testing was done yet. Support for Blender 2.79 is questionable because of some features missing in the old sound api, but it works at least with Real Time Analyzer.
I would like to receive some feedback from you. I would like to know if there is any space for this add-on in the world. And if you like this idea, I would really appreciate any suggestions, bug reports, feature requests…
Here is my youtube channel with some videos created with it.
