Abstract
This document presents a general description of the Syter audio
digital processor. This processor has been incorporated in the GRM digital
studio. Second part of the paper gives more concise informations about the
outlines of the experimental software and its development towards- a. higher
level program for use by electroacoustic musicians. This part should be read
as a progress report.
1 - Introduction
The main purpose of the Syter project is to provide electroacoustic
musicians with new tools for sound manipulation in real time, using the digital
technology. As "concrete" approach to electroacoustic music is a rather practical
and empirical one, a special benefit is expected from real time interaction and
audition.
Specific design goals may be related to this particular musical
environment
Capability of treating and transforming natural recorded sounds
with good audio quality; this feature looks to us more important
than the synthesis performances.
-.Special attention paid to manipulation of continuously varying
command parameters. The musicians whom we work with may sometimes
use notes, are dealing often with discrete events,but they do have
a particular interest in evolving phenomenons.
Of course, we have to consider more common constraints:costs, ob viously and also ease of programming and size, keeping in mind a later possible
realization for live performance (actual system is mainly intenddd for studio use).
