    Abstract

    This paper examines a recently introduced technique for sound synthesis that uses a coefficient modulated allpass filter to cause phase modifications to its input signal. The intention in this work is to outline some of the properties of the coefficient modulated allpass filter and then to establish a connection between this new method and the older technique of Phase Distortion. Results are presented to demonstrate how the allpass technique provides a spectrally richer output signal.
