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).

I’m writing an iOS app in Swift (will also write a Mac version later) and would like to add pitch detection. Is there an open-source project that does frequency pitch detection? Would I use AVAudioSession to capture the audio, then drop down into CoreAudio to do the pitch detection?

In my initial research, I’ve learned there are many algorithms and ways to go about doing pitch detection - each having strengths and weaknesses.

Can someone please point me in the best direction to get started?

Thanks,
