function FF = computeAllStatistics(fileName, win, step)

% This function computes the average and std values for the following audio
% features:
% - energy entropy
% - short time energy
% - spectral rolloff
% - spectral centroid
% - spectral flux
% 
% ARGUMENTS:
% fileName: the name of the .wav file in which the signal is stored
% win: the processing window (in seconds)
% step: the processing step (in seconds)
%
% RETURN VALUE:
% F: a 12x1 array containing the 12 feature statistics
%
