Extemporization for Begonia, Euphorbia, and Guiana was a sound performance delivered to a botanical audience. For this work, I implemented a “bioacoustic filter,” which allowed me to process my voice and remove all frequencies which fall outside of a plant's acoustic sensibility. The filter uses fourier fast transform (FFT) to produce a spectral analysis of an incoming signal. That analysis is then compared to data appropriated from research which investigates the frequency responses of plants, and the signal is resynthesized in a process called RFFT. To my human audience, the resulting audio serves as an approximation of how my voice would be perceived by a plant.
