The Spatbox: An Intuitive Trajectory Engine to Spatialize Sound

Résumé

This paper presents the software part of the spatbox project 1 : an interface to intuitively generate 3D trajectories and to spatialize them in real-time on a loudspeaker array with Ambisonics. Each trajectory is described by a parametric curve, where each of the coordinates varies according to a configurable LFO. Depending on the LFO parameters, many trajectories can be generated. The similarity of the interface to that of a synthesizer allows the user to quickly get to grips with the tool. In particular, it is possible to create trajectory presets for fixed parameter configurations. An implementation in the Faust language is made and a visual feedback tool is introduced. Some additional features for the trajectory modification are proposed: choice of the coordinate system, trajectory scaling and acceleration, Doppler effect, hold/reset and rotation/translation functionalities.
