Cool, is it like a kind of audio visualization?
I usually add a credit for songs in my videos as a caption or at the end of the video.
I use microsoft movie maker for captioning my videos, but you can add captions with other software like OBS (which allows you to add logs, titles and other things as part of your main recording stream).

Otherwise at least scale it up so people don’t have to see the static UI around your creation.

Actual demo:10/10 looks very cool
