% A soundlist consists in different .wav files name contained in an ASCII file (.txt) preceeded by an index
% - The first line may contain the path for searching all the files or a blank line

%				.name
%				.path

% if % or * are present, the lines are not taken into account
% if # at beginnning stop the sound list load...
% you can also put an index in front of each sounds
