about

The recordings on "The AAS-4 System" document the use of a novel signal processing technique in which time-varying allpass filters are placed into feedback networks, producing synthesis structures capable of producing interesting emergent sonic behaviors.

Ideas from the field of computational aesthetics are employed to allow a large system built from these synthesis structures to become “aesthetically aware.” Many theories about computational aesthetics center around a favorable balance between order and complexity in a stimulus - a successful artistic work is neither too orderly nor too complex. Using a model of human perception based on the “mere exposure” effect, which describes how listener appreciation and boredom change as they experience repeated exposure to a stimulus, the system autonomously determines when and how to modify its own parameters to avoid repetitions that may lead to boredom in listeners.

The result, created over three years of research and development, are a series of fully generative compositions, synthesized and structured completely in software.

The AAS-4 System is described in greater detail in "Generative Audio Systems: Musical Applications of Time-Varying Feedback Networks and Computational Aesthetics," available at escholarship.org/uc/item/9fk810hq
