+% SimScene is a set of Matlab functions dedicated to the simulation of acoustic scenes.
+% This tool is specifically tailored to the evaluation of machine listening systems.
+% Thus, extensive and precise annotation of the scene content is provided together with the simulated scene.
+%
+% This tool is a research tool, provided as-is with the hope that it will be
+% useful and easy to adapt to the needs of others. Do not hesitate to provide
+% us with feedback at the following mail address: mathieu.lagrange@cnrs.fr
+%
+% SimScene have been tested on Matlab R2013b. The input audio files must be sampled at 44100 Hz.
