An important step in this line of research is to perform a series of experiments to quantify the effectiveness of the VR audio system as a function of operating parameters. Experiments are scheduled to determine the localization accuracy possible with the existing Mercator spatialization engine over a range of bandwidths. The results of this work should be helpful in determining the appropriate...

The aim of this article is to compare two multi-speaker spatialization techniques Vector Base Panning (VBP) and Ambisonics on a particular loudspeaker layout. Theory is presented for configurations in the horizontal plane. A way to deal with the elevation effect for such layouts is proposed. A new "local" panning method is introduced. VBP and Ambisonics are compared on a 5.1 configuration by me...

This paper proposes an aesthetic and formal analysis of the work Forma del respiro by the Italian composer Michelangelo Lupone. Written in 1993 at the CRM – Centre for Musical Research, Rome, the piece for magnetic tape is an exploration of the expressive potential of the granular synthesis technique, and it submits to analysis a high number of parameters (timbre, frequency, dynamics, temporal ...

In this paper, we propose powerful virtual image processing tools (face cloning and video spatialization) which can be useful to design new teleconferencing systems offering a better comfort for users even if very low bit rate links are used. These tools allow a new teleconferencing concept, relying on the metaphor of a virtual meeting room where the participants can choose their position and p...

The Sound Flinger is an interactive sound spatialization instrument that allows users to touch and move sound. Users record audio loops from an mp3 player or other external source. By manipulating four motorized faders, users can control the locations of two virtual “sound objects” around a circle corresponding to the perimeter of a quadraphonic sound field. Physical models that simulate a spri...

Real acoustic objects have spatial width and characteristic radiation patterns. Techniques are described for efficiently synthesizing these qualities, by encoding with spherical harmonics. This approach naturally lends itself to Ambisonic reproduction, although it can be usefully applied to other forms of reproduction.

Level-of-detail is a concept well-known in computer graphics to reduce the number of rendered polygons. Depending on the distance to the subject (viewer), the objects' representation is changed. A similar concept is the clustering of sound sources for sound spatialization. Clusters can be used to hierarchically organize mixels and to optimize the use of resources, by grouping multiple sources t...
