Augmented Feedback: A Compositional Approach to Acoustic Feedback in Digital Spaces

Abstract

The research entitled "Augmented Feedback", is focused on developing a compositional practice, centered around acoustic feedback processing in digital spaces. I wish to explore acoustic feedback that occurs in virtual spaces, including the hybrid world of physical and digital space and physical phenomena that occurs from the excitation of feedback through microphones and loudspeakers. I will focus on experiments, reflections, developing techniques and functions that I have discovered while composing and experimenting with pieces that have used processed acoustic feedback as sonic material, microphones and loudspeakers as instruments. The outcome will have brief background and development reflections about my approach to feedback around my personal compositional practice, the historical side of feedback and how it relates to the works of other composers and artists, technical and philosophical content of feedback in compositional situations, and how my compositional approach led me to the term “augmented feedback”. “What if the sonority of feedback was not the center focus point of a piece? What else can we develop by using feedback and imagining it in different sonic landscapes? What is the mystique of its nonlinearity? How can we deal with microphones and loudspeakers as a musical instrument through using software environments?” are the main questions that drove me into researching feedback. Dividing these questions into subcategories: conceptual and compositional.
