Calling C/C++ from python programs works very well. The other way around not so much. I haven't done it but I assume you would have to embed a python interpreter into mixxx and bundle it with all the dependencies this madmom depends on. I haven't seen the code but if they want to be fast they either have written C/Cython modules and/or make extensive use of numpy. In both cases the numerics should be fairly easy to implement directly in C++. best Max > Windows, Mac OS X and Linux (probably *BSD family also). Unix is easy > but Windows is pain.
