As the title says: Does such a thing exist? There was a version for Mac OS 8-9, but as far as I know, there really isn't one for OS X...
Im not really sure whats available but i know for a fact you can get the Java Runtime on os x so you can give Blind Audio (http://www.hydrogenaudio.org/forums/index.php?act=ST&f=2&t=1659&hl=blindaudio) a try. Its more or less abandoned for the time being but it still does the job.
There seems to be mentions of some other cross platform alternatives as well that were in the works at the time that thread was active so you might want to check with those authors as well. Good luck
