Before getting started This is a post I made back on the website I had while in college. That site has since been abandoned (sorry about that), but since I’ve started a new one I thought I’d import this here for legacy purposes. There are other open source pitch detection projects out there now using more modern language constructs and I’d recommend checking those out before this. Pitch detection is a relatively common thing to do in the audio realm.
