Reading and writing of files now is done by soundfile since there seems to be a bug with writing .wav files with librosa (mplayer would play them as rubbish). Added soundfile as a requirement.

% 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: [e-mail]
%
% SimScene have been tested on Matlab R2013b. The input audio files must be sampled at 44100 Hz.
