title: Real-time pitch detection using FFT
body: <p>I'm trying to do real-time pitch detection using C++. I'm testing some code from performous (<a href="http://performous.org/" rel="nofollow noreferrer">http://performous.org/</a>), because everything else hasn't worked for me. I know for sure that this works, but i just cant get it to work. I've been trying this for a few weeks now, and I haven't been able to get any pitch detection code working.</p>
