Adaptive tuning using theremin as gestural controller
Alexandre Torres Porres, Jônatas Manzolli · 2007
This work presents an interactive device to control an adaptive tuning and synthesis system. The gestural controller is based on the theremin concept in which only an antenna is used as a proximity sensor. This interactive process is guided by sensorial consonance curves and adaptive tuning related to psychoacoustical studies. We used an algorithm to calculate the dissonance values according to amplitudes and frequencies of a given sound spectrum. The theoretical background is presented followed by interactive composition strategies and sound results.
