aubio is a common starting point for open source pitch detection, as is the CLAM project. however, my impression is that to do it well, you want non-realtime analysis, which means that normal AU's are not ideal. the VAMP plugin suite is another open source API and set of plugins specifically designed for non-realtime analysis.
please don't use these sources if you intend to write proprietary software (though of course, nothing is going to stop you).
