For this project, I chose to use an acoustic guitar as the input instrument. It is a Taylor electric-acoustic, and I simply plugged it into a mic input on the workstation to get sound input into ChucK. From there, I used two Frequency/Amplitude tracking instruments, both slightly modified versions of the amplitudeFrequencyTracker.ck in the starter code. The first is uses a simple FM synthesizer as the output instrument, attaching the frequency tracker to the carrier pitch and the amplitude tracker to the FM ratio. The second instrument is a StifKarp output instrument, modified to do basic arpeggiation on top of the tracker frequency. This leads to a cool arpeggio effect. I used the two in different parts of the piece, and combined them to get a wavy FM synth combined with individual notes and arpeggios from the StifKarp.
For the part of the assignment involving writing a score on top of the nature file, I interpreted it very loosely. The biggest event in my score was a large bee buzz in the middle of it, which I used as a cue to increase the intensity of the instrument. This is the spectrograph of the portion of the nature track I used.
