create data set signal

hi

I use this code to read the wav one by one and save as csv, is there any way to make matlab do it for all file

% get a section of the sound file
[x, fs] = audioread('a(550).wav');   % load an audio file
N = length(x);                      % signal length
t = (0:N-1)/fs;                     % time vector

save a(550).csv x -ascii -double

Note: you will want to use the function form of save

save(filename, 'x', '-ascii', '-double')

However, note that the save command cannot do comma delimiter such as you would expect for csv files.

 dlmwrite(filename, x, 'precision', 15)   %defaults to comma delimiter
