Any update on how to achieve real-time pitch recognition with UE4? Any plugin?

I've noticed the new engine has new spectrum analysis functions https://docs.unrealengine.com/en-US/...sis/index.html.
I hoped I would be able to feed midi pitch frequencies to GetMagnitudeForFrequencies function and then get frequency with Max magnitude but the result is incorrect.
Pitch recognition is probably a bit more complicated than this.

dan.reynolds could you please help me out here?
