Sound driven visual Motion and Media
(Physical media)
Preface and Introduction
Cymatics is the
study of visible sound and vibration, typically on the surface of a plate,
diaphragm or membrane.
Direct ocular viewing of vibrations involves exciting
inorganic matter such as particulate matter, pastes (both magnetic and non
magnetic) and liquids under the influence of sound, although recent research
has extended the range of media to include organic matter and the range of
viewing has been extended to include the light microscope.The generic term for this field of
science is the study of 'modal phenomena,’ named 'Cymatics' by Hans Jenny, a
Swiss medical doctor and a pioneer in this field. The word 'Cymatics' derives
from the Greek 'kuma' meaning 'billow' or 'wave,' to describe the periodic
effects that sound and vibration has on matter.The apparatus employed can be
simple, such as a Chladni Plate (a flat brass plate excited by a violin bow) or
advanced such as the CymaScope, a laboratory instrument that makes visible the
inherent geometries within sound and music.
From wiki
This class and projects
will be about the exploration of audio driven patterns and graphics with an
intention to create an instalation.
Project One
Circuit Bending and Electronics
Duration 3 weeks
Circuit Bending and Electronics
Duration 3 weeks
David Hall and Zizzic Cymatics 2011
Each person will buy two or more battery
powered electronic
audio devices. (Must be battery powered). One will be a
speak and spell machine the other will be up to you.
Week One – Introduction
Week Two – Disassemble and initial tests
Week Three – Adding components for control and interaction.
Note. As well as buying electronic audio devices you will also need soldering irons and various other components.

Project Two
Signal Processing and Sound
Duration 3 weeks
PREFACE
Sound signals have been represented
graphically for as long as graphics has existed. However with a computer added
to the working pipeline its possible to envisage many new and unexplored
visualizations of audio data.
The basis of motion graphics is often the
relationship between sound and image. However as media breaks out of the
confines of the screen new methods and approaches to audio data output are
emerging.
Procedure
We will take our sound source from the first project. Processes it digitally then output it three dimensionally via the laser cutting fabrication process.Week One - Introduction

Project Three
Real-time and interaction or Pre rendered
Duration 6 weeks
For the final part of our project you have two choices.
Option One- Pre Rendered Animation
Using trapcode sound keys you can use your audio signal to
generate motion graphics in After Effects. The visual style should be abstract
I suggest.
Option Two- Real Time interaction
Using your sound and circuit knowledge you will hook up your
device to
a computer and use the signal to modify / change an image.
Software could be Quartz composer ( for mac ) or VVVV or which
ever program you choose.
