mathieu@14: % SimScene is a set of Matlab functions dedicated to the simulation of acoustic scenes.
mathieu@14: % This tool is specifically tailored to the evaluation of machine listening systems.
mathieu@14: % Thus, extensive and precise annotation of the scene content is provided together with the simulated scene.
mathieu@14: %
mathieu@14: % This tool is a research tool, provided as-is with the hope that it will be
mathieu@14: % useful and easy to adapt to the needs of others. Do not hesitate to provide
mathieu@14: % us with feedback at the following mail address: mathieu.lagrange@cnrs.fr
