 % In this loop I'm looking for the sound files that are realted to M.
 % By reading them, I'm making audio processing so that I can find the
 % number of claps. My algorithm looks for mean of an array and then set
 % some value as threshold. Therefore by iterating over indexes , I should
 % be able to observe if there is a clap occured in sound file.
 % 2-2 has 5 claps.
 % 2-1 has 1 clap
 % Other ones are default files.
