Abstract
The Source-Dependent Instrument is a signal processing and signal generation system that uses one or more signal event generators that can be functionally activated and controlled by the analysis of an external input signal. These output generators and signal processors can be set to re-synthesize aspects of the input or synthesize a more complex or perceptually shifted output based on the input.
