Editing Phase distortion synthesis (section)

{{Short description|Electronic sound synthesis method}}
'''Phase distortion''' ('''PD''') '''synthesis''' is a synthesis method introduced in 1984 by [[Casio]] in its [[Casio CZ synthesizers|CZ range of synthesizers]]. In outline, it is similar to [[phase modulation]] synthesis as championed by [[Yamaha Corporation]] (under the name of [[frequency modulation]]), in the sense that both methods dynamically change the harmonic content of a carrier waveform by influence of another waveform (modulator) in the time domain. However, the application and results of the two methods are quite distinct.

Casio made [[Casio CZ synthesizers|five different synthesizers]] using their original concept of PD synthesis (with variations). The later VZ-1 and co's synthesis method '''Interactive phase distortion''' is much more similar to the aforementioned phase modulation, rather than a direct evolution of phase distortion; see below.
