FFT-Based Real-Time Tracking

When I first began this project, I tried very hard to listen to all the distinct sounds in the nature piece that I was given. After 15 minutes, I was really confused and found it hard to pick which parts I wanted to focus on (see below, a giant mess of a score). Then, I simplified the piece to more guesstimations of five distinct voices (see simple score below).

Next, I began by choosing the birds, the cricket-like chirps, and a portion of the deep-rumble (or gargle) sounds. The bird noises was a result of rubbing my fingers against the table next to a microphone with the amplitude tracker. The chirps were created by snapping my fingers with the aplitude frequency tracker, and the gargles were created by my gargling with the aplitude spectrum tracker. Both the bird noises are common throughout the score but vary in frequency/timing so I tried to reflect this. Although the gargles appear more commonly the nature piece, I just chose a small slice of the gargle noises to reflect the "whoop whoop" event torwards the end of the nature score.

Finally, I added two short melodies to give the piece a little more flavor.
