 This is the code that I try to do, the wav_data is the data of 
test5.wav,after get the data it show in 
[302712,2]which have 302712 rows and 2 columns. 
Next, I use the sortrows to rearrange the data and save in e, 
so e is the new array of .wav. But, how to save as new wav file
 after get new array of e? I not sure my method is correct or not... 
if true
  filedir=dir('test5.wav');
disp(filedir);
y = cell(1,length(filedir));
fs=y;
for ii = 1:length(filedir)
  [y{ii},fs{ii}]=audioread(filedir(ii).name);   
end
for ind_wav = 1:length(y)
  wav_data = y{ind_wav,1};
end
p=size(wav_data);
disp(p);
d=ndims(wav_data);
e=sortrows(wav_data);
%disp(wav_data);
disp(e);
end
