“…The original implementation of Phase Distortion is based on modulating the phase increment used to index a fixed wavetable, not allowing for the use of arbitrary input signals. Recent research [3], [4], [5], [6] and [7] have proposed alternative methods extending FM-related techniques to enable such inputs. Of these, the allpass method [5] seems particularly suited to Phase Distortion applications.…”

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.

“…However, the use of a DSP unit enables implementation of a variety of sound processing techniques and synthesized algorithms. Lazzarini, Timoney, and Lysaght (2008), for example, describe adaptive frequency modulation synthesis based on an acoustic oscillator instead of an electrical oscillator. Smith (2010) in Physical Audio Signal Processing describes many different sound effects that can be implemented digitally, such as virtual distortion.…”

“…In the 1990s, interest in these techniques diminished, even though some important novel methods were still being proposed, such as that of Puckette (1995). More recently, distortion techniques have been used in new synthesis algorithms (Lazzarini, Timoney, and Lysaght 2008b) and for audio effects (Lazzarini, Timoney, and Lysaght 2007, 2008a, 2008c.…”
