“…Many artists and researchers have tried to make sound with drawing (such as Iannis Xenakis's UPIC [17], Golan Levin's Audiovisual Environment Suite [12], Amit Pitaru's Sonic Wire Sculpture [15] ). In contrast to such previous works, DrawSound uses the ordinary paper and pens to synchronize the drawing activity with the sound representation.…”

DrawSound is a drawing instrument for sound performances that combines multi-touch input technology with the expressive character of drawing. The instrument is intended to be used in two different art projects, The SINE WAVE QUARTET, and aeo. In this paper, we describe the implementation of DrawSound with three different pens and show how we design the two different sound performances. We also explain our preliminarily observations about the unique characters of DrawSound.

“…For the music field, there have been a lot of researches with IGA too [11]. From these researches, IGA is found to be useful method to reflect human sensibility to create some music better than GA [12], [13].…”

In recent years, many kinds of sign sounds have come into use in our daily life. The purpose of sign sounds is to communicate a message. However the ease of message understanding and listening comfort have rarely been taken into consideration. Because people have different tastes and attach a different "image" to sign sounds according to their individual sensibility, it is important for each person to be able to make melodies freely and easily, and customize sign sounds. We propose a sign sounds design system using an Interactive Genetic Algorithm (IGA). The proposed system produces a melody of two bars based on this IGA. A melody is considered to be a sort of "organism," whose chromosome consists of genes indicating the length, pitch, and velocity of the notes of the melody. Experimental results showed that this system is effective for generating sign sounds. In creating auditory signals, it was found that the method of evolving part-by-part is better than the method of evolving the whole two bars.

“…Since a great deal of software development is required to integrate new methods fully within the compositional system, each method is implemented first in a simple form within a test environment; later if user interest merits, the model is developed further. For instance, waveshaping is available in a basic implementation (Roads, 1979); granular synthesis (Roads, 1978) and the Karplus-Strong (1983) algorithms are under development. Another algorithm that is already in use is based on additive synthesis equipped with amplitude and frequency envelopes controlling eight simultaneous waveforms.…”
