Blueprint audio library

It’s cool, but I’m still trying to figure out things like:

  1. how to use audio from the microphone as an audio source.
  2. how to change the sample size to get better separation between the frequency bands.
  3. how to apply a FFT Window to the sample data to reduce leakage (Hamming, Hanning, Blackman, etc)
  4. some way to limit the frequency range (anything from 16k-40k is a bit useless in most cases)

But its a great start. Can’t stop messing it.
