Francesco Scagliola
Bio [2009]
Francesco Scagliola is a composer. He graduated with full marks in piano,
electronic music, and composition in 1998 as a specialist in musical computer
science from Tempo Reale, the musical research, production, and didactics
center managed then by Luciano Berio. In 1999 he specialized in musical
composition with Azio Corghi at the National Academy of St. Cecilia, where
he earned a degree in composition in 2003. He is dedicated to musical
research, particularly problems of computer modeling of composition
processes. He is currently Professor of Electronic Music at the "Niccoló
Piccinni" Conservatorio in Bari. He is also an assistant professor under
Prof.
Corghi and Prof. Bacalov (Academy Award winner, 1966 and 1995) for live
electronics and multimedia in summer courses at the Chigiana Musical Academy, where he has taught since 2001.
Project Title
A Modified Gabor's Auditory Representation Model for Cellular Automata
Project
In the exploration of the computational universe, a crucial role is played
by visual representations. As an alternative to this technique, in this
project an auditory approach is adopted—a possibility also suggested by
Stephen Wolfram in his NKS book (p. 585). This project uses granular sound synthesis,
and in particular a modified Gabor's auditory representation model, for
rendering and analyzing the complex behaviors of cellular automata. The
basic idea of these techniques is to use the value of the cell at column f
and row t of the automaton computation as the amplitude of an
elementary component ("grain" or "acoustical quantum") characterized by
frequency f and occurring at time t. The collection of grains is expected
to form a complex, evolving sound. The evolution of a cellular automaton is
thus interpreted as a sonogram where each row is a spectrogram.
The reason for choosing the Gabor model is that it is based on the
physiology of sound perception and on psychoacoustic criteria that Gabor
himself investigated. It is hoped that reflecting parameters
of the human auditory system will yield advantages in terms of the
artistic potential of the method. In particular it is hoped that, for some
families of CAs, new timbres will emerge at the microstructure level as well as
perceivable larger-scale patterns at the macrostructure level.
