a music visualizer

I want to develop a music visualizer using openFrameworks.
Since it supports fmod, I hope to use it to do the music feature extraction, and then do the graphic part.
But the problem is, I don’t know how to realize this project, is there any document about fmod in openframeworks or music visualization development?

Your question is a bit vague, depends on what you want to do. First you should get familiar with OF by looking at the examples and making a lot of small apps. And like you said, you want audio analysis so you should learn how to implement it in OF. And for “graphic stuff” there is a very broad range of tutorials depending on what you want to do.

I’ve googled fmod openframeworks and apparently there is no support for it

so you’d have to do it yourself, although I’d say it requires at least a bit of experience in C++
