Simulating the soundscape through an analysis/resynthesis methodology

This paper presents a graph-based system for the dynamic generation of soundscapes and its implementation in an application that allows for an interactive, real-time exploration of the resulting soundscapes. The application can be used alone, as a pure sonic exploration device, but can also be integrated into a virtual reality engine. In this way, the soundcape can be acoustically integrated in the exploration of an architectonic/urbanistic landscape. The paper is organized as follows: after taking into account the literature on soundscape, we provide a formal definition of the concept; then, a model is introduced, and finally, we describe a software application together with a case-study.

Imaginary soundscapes: the SoDA project

The SoDA (Sound Design Accelerator) project aims at providing a flexible software environment for soundscape generation. Based on semantic information, it provides both an annotation schema and an annotated library of sound files that operates in relation to a generative system that delivers the final audio content. SoDA provides the user with various forms of interaction: from incremental assisted exploration of semantic and audio content in real-time to completely automated off-line soundscape composition. In this paper we describe the semantic and audio components and the various interaction modes.

All the Numbers End in Numbers. On a Work by Alighiero Boetti

Alighiero Boetti is one of the most representative contemporary Italian artist and his opus is raising a constantly growing international interest. Many of his works can be realized on very different supports and make use of algorithmic procedures. This contribution analyzes a minimal work, consisting only of the linguistic description of a process, with the aim of demonstrating that, in spite of its simplicity, it shows various relevant features of Boetti’s aesthetics.

Tabula ex-cambio

Tabula-ex-cambio is an interactive installation that delivers visual and audio content. It works as a sort of perpetual billiard game, powered by the data originating from the trend of a stock exchange index. The visual content is a real-time animated 3D computer graphics, that represents a billiard game where each ball is associated with a stock in the index. The audio content is an electroacoustic music composition featuring as many layers of sounds as stocks in the index. All the balls in the billiard are musical sources that play an iterated sequence of sounds while moving on the billiard table; each sequence is altered in frequency by the trend of the related company index. The final delivered visual and audio contents depend on the interaction with the user, who can select a view/listening point on the billiard game. The physical installation consists of a deformed billiard structure connected to a stele through cables; the stele is a vertical display where the billiard game takes place. The visual display relies on the graphic engine Ogre, while the aural display is implemented in SuperCollider. The installation was exposed in Shanghai, Beijing, Birmingham, and Terni (Italy).
