I was playing around with Sonic Visualizer last night, following these great video tutorials. In one of them Mazurka Plugins are used, for which there were no downloadable OS X binaries until now:

Download mazurka-plugins.dylib (OS X Yosemite, 10.10)

I’m not sure if these will work with previous versions of OS X, but maybe give it a try.

If you want to try compiling yourself, here are the sources I used.
You’ll also need XCode with Command Line Tools and fftw3 installed.
