Abstract

This paper describes work on a graphical user interface (GUI) for sound synthesizers based on interactive evolutionary computation. The GUI features user-controlled interpolation for fast auditioning and evaluation of relatively large populations. Interpolation behaviour is considered with reference to usability and the psychoacoustical "just noticeable difference". Different methods of generating new populations are tested in a formal usability experiment: a method giving a type of consistency of behaviour and increased population diversity is shown to give improved performance over two methods lacking these characteristics.
