The exploration of sound spatialization is a preoccupation of many composers and performers of electroacoustic music. Two-channel stereo techniques are widely used in the genre, but more sophisticated forms of sound spatialization are often restricted to those with access to significant technical resources. Recent technological developments have increased access to high-quality, multi-channel a...

We survey works and applications of visual programming for the control of sound spatialization in the OpenMusic computer-aided composition environment. Several salient aspects of the control and spatialization processes are described, such as the high-level description of spatial sound scenes, their unfolding in musical or computational time flows, as well as the concept of spatial sound synthe...

‘Real-time Sound Spatialization, Software Design and Implementation’ explores real-time spatialization signal processing for the sound artist. The thesis is based around the production of two prototype software projects, both of which are examined in design and implementation. The first project examines a conceptual method for performance based spatialization mixing which aims to expand existin...

An approach to the creation of musical material, coined here as “textural composition,” addresses aesthetic consequences of real-time stochastic sound mass composition. Musical texture as source material exists between sound-object (singular) and sound-objects (plural), inducing an aesthetic of the intermediary. Since sound diffusion is inextricably linked to composition, spatialization require...

In this paper we will report on the use of real-time sound spatialization in Challenging Bodies, a trans-disciplinary performance project at the University of Regina. Using well-understood spatialization techniques mapped to a custom interface, a computer system was built that allowed live spatial control of ten sound signals from on-stage performers. This spatial control added a unique dynamic...

The growing volume and complexity of the World Wide Web creates a need for new forms of interaction with information. Spatial metaphors have been in the focus of interface research for a number of years. Recently, a related concept called spatialization has emerged as one possible strategy for dealing with modern information glut. However, the term remains ill-defined. We present a definition o...

In this paper, we describe a head-model based on interaural cues (e.g. interaural level differences and interaural time differences). Based on this model, we proposed, in previous works, a binaural source spatialization method (SSPA), that we extended to a multispeaker spatialization technique that works on a speaker array in a pairwise motion (MSPA) [1], [2]. Here, we evaluate the spatializati...

Most common techniques for spatialization require the listener to be positioned at a “sweet spot” surrounded by loudspeakers. For practical concert, stage, and installation applications such layouts may not be desirable. Distance-based amplitude panning (DBAP) offers an alternative panningbased spatialization method where no assumptions are made concerning the layout of the speaker array nor th...

The transfer of multichannel spatialization schemes from the studio to the concert hall presents numerous challenges to the contemporary spatial music composer or engineer. The presence of a reverberant listening environment coupled with a distributed audience are significant factors in the presentation of multichannel spatial music. This paper presents a review of the existing research on the ...

Information visualization is an interdisciplinary research area in which cartographic efforts have mostly addressed the handling of geographic information. Some cartographers have recently become involved in attempts to extend geographic principles and cartographic techniques to the visualization of non-geographic information. This paper reports on current progress and future opportunities in t...
