Remember the arcade game "Galaga", circa 1982 or thereabouts? Well, I was messing around in a purposefully unstructured way with FFT and IFFT and accidentally created the sound of the bees from Galaga. It works by listening to your voice on the mic, taking the centroid of the FFT of your voice, then synthesizing a frequency spectrum with the centroid as the fundamental frequency and finally doing an IFFT on that.

What I was haphazardly trying to do was play around some more with guitar-speaking a bit, so I imitated the guitar spectrum peaks that I found on the web somewhere and did an IFFT on that. It actually makes a somewhat musical-instrument-sounding note when played by calling the note() function in the program. However, when I applied the centroid I think I miscalculated the frequency conversion somewhat, and accidentally discovered the bees!

I will now go back to trying to make guitar-speech, but the bees were a fun little accident that I thought some ChucKists might enjoy. Cheers!

Converts microphone input into Galaga Bee voices, very funny. Turn up the volume to create feedback, resulting in a bee storm!
