This blog post has some interesting works, visualizing sound in very different ways. https://en.99designs.com.co/blog/design-other/sound-visualization-design-inspiration/ https://en.99designs.com.co/blog/design-other/sound-visualiz... Especially this one contains a lot o things of what you seem to by trying to do. https://vimeo.com/111593305 https://vimeo.com/111593305 That said, I don't think you will get very interesting patterns from rain without quite some pre-processing, because rain sound is fairly close to just brown noise. E.g. what I would try top of mind is to filter out only few of very load drops and start working only with them for the visuals, mixing the rest back in audio only as calming background. It's still going to be random, but should be able to make it to look much more interesting. Also stereo recording will make a big difference for the audiovisual experience.
