Hi,
 
 
I'm a student and i want to create a routine "m-file" to be able to read all the  "wav" files  that I have in my current directory. I found auload to do it like this:
 
payload = auload("audio.wav");
save audio.mat payload
auplot(payload);
 
but i want to create a loop or mayba change the fonction auload i mean in place to accept the name of the file, can accept a variable in order to read all wav files. Does anybody knows how can i do it?
 
Thanks
 
Miguel

I haven't tested it, but is this the sort of thing you're looking for?

function [wavdata] = auloadfiles(filter)
   if (nargin < 1)
     filter = "*.wav";
   endif
   wavfiles = dir (filter);
   N = numel(wavfiles);
   wavdata(N).name = "";
   wavdata(N).data = [];
   wavdata(N).rate = 0
   wavdata(N).fmt  = "";
   for n = 1:N
     wavdata(n).name = wavfiles(n).name;
     [wavdata(n).data, wavdata(n).rate, wavdata.fmt] = auload  
(wavdata(n).name);
   endfor
endfunction
