Research and implement a way to detect new "points of interest" in the audio input.

Basically, rather than visualize frequency amplitude, we want to visualize changes in dominant frequency amplitude.

i.e.:

detect when a the dominant frequency bin has changed; perhaps behave differently depending on the difference in bin index between the new dominant frequency and the old one
second order FFT (over the history of each frequency bin)?
sudden changes in overall scale (autoscale) (i.e. detect sudden silences or sudden loudness)
tie display events to custom narrow frequency bins
