Six Microphones is a site-determined piece composed entirely of feedback: nothing is generated, only amplified. The piece is executed by an autonomous control system contending with its environment as it attempts to perform a score. The resultant sounds emerge from this complex interaction between system and space.
Each of the six microphones complete an independent feedback loop with two speakers using twelve (6x2) PID controllers. Over the duration of the piece, each controller forces its microphone-speaker-feedback-loop to converge on amplitude set points encoded in a score file. While achieving these amplitudes— and interacting with each other in unanticipated ways— the control systems discover resonant frequencies and modulations determined by the geometry of the listening space, its materiality, and the location of any inhabitants.
The score is comprised of six parts and an overture. Within each, the microphones enumerate 64 (2^6) combinations of ON and OFF. The six parts differ in the relative amplitudes of ON microphones, the duration of their onset, and the speaker to which each ON microphone is assigned. All tones, timbres, and modulations emerge from the indifferent interaction among these parameters and the environment during a performance; they cannot be anticipated beforehand.
