How can I create a music visualizer based on my own synaesthetic patterns?

You’re probably going to need to learn how to use animation software. They are pretty complicated, and can take years to master. I’m not sure if flash animation could do the kind of thing you want, or if it would be after effects or something else.

If you have a Mac, I would look into Quartz Composer. It comes with the operating system, under developer tools, and can be used to create real time music visualizations (among other things.) It may take some time to learn, but if your really serious about it this would be a good direction to go.

@quasi good point. I didn’t even consider that route, although it might be trickier than learning animation software. I think either way, you’re probably looking at a massive commitment in time and energy to make it happen. That said, I think it would be wonderful to be able to get a glimpse into what your experiences might be like.

One option that might be possible is to link up with the graphics art/animation department of a local college and explain to the professor that you’re trying to express your visual synesthetic experience. The artistic/academic benefits alone might be enough to convince him to find some students willing to work on a project of sharing your experiences with the world.

@gorillapaws & @quasi Thank you so much for the informative answers. I would certainly be willing to take a class to learn how to use such software. This is something I have always wanted to create. I will inquire about it at my local college.
