----------------------------Original message---------------------------- A source that I recently located may be of interest for sound/image theory: _Audio-Vision; Sound on Screen_ by Michel Chion, Forward by Walter Murch, Edited and Translated by Claudia Gorbman. Columbia University Press, New York. 1994. I hope that this is helpful. If there is more interest I may be able to recommend other sources directly. Jesse Burden([log in to unmask]) Mr.5x5 o----o
