See the FAQ for two code samples: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

this shows how to save txt file and other but it does not do the wav reading

[Walter Roberson]

projectdir = 'Name_of_folder_goes_here';
dinfo = dir( fullfile(projectdir, '*.wav') );
filenames = fullfile( projectdir, {dinfo.name} );
for K = 1 : length(filenames)
   thisfile = filenames{K};
   [~, basename, ~] = fileparts(thisfile);
   newfile = fullfile(projectdir, [basename, '.txt']);
   [data, fs] = audioread(thisfile);
   save(newfile, 'data', '-ascii', '-double');
 end

This will create a .txt file in the same directory and with the same basic name as the .wav file.

These files will not be efficient ways to process the signals. About the only reason to create such files would be if you were processing the files with external software -- and if you were then it would be important to know what file format the external software needed.
