#65 Digital Emulation of Distortion Effects by Wave and Phase Shaping Methods
Joseph Timoney, Victor Lazzarini, Anthony Gibney, Jussi Pekonen
This paper will consider wave and phase signal shaping techniques
for the digital emulation of distortion effect processing.
We examine in detail how to determine the wave and phase shaping
functions with harmonic amplitude data only first, and then
after including the harmonic phase data. Three distortion effects
units are used to provide test data. Wave and phase shaping functions
for the emulation of these effects are derived with the assistance
of a super-resolution frequency-domain analysis technique.
In complement to this, we describe an alternative time domain
method for determining phase shaping functions using Dynamic
Time Warping. Finally, we propose a method for assessing the
frequency dependency of distortion effects to help the design of
multiband wave and phase shaping functions.
