Sound synthesis and composition with compression-controlled feedback
This paper introduces a method of sound synthesis that is based on the use of automatic gain control (AGC) in a time-delayed feedback loop. The approach, which the author calls "Compressed Feedback Synthesis" (CFS), can be conceptualized as a special expansion of a generalized comb filter, where feedback gain can be unity or greater. The system can be expanded with additional processing in the feedback loop to create a highly flexible and sensually engaging sound materials. The use of CFS in the author's audiovisual composition Sinus Aestum is discussed, including specific solutions to the challenging of controlling such a system compositionally.
