Hi, I have a problem in matlab .how to read matrix of wav files (element by element)by using wavread(); . I tried it but it not acceptable . I write this but i have an error. I want to read folder dynamic not static .

[filename, pathname, filterindex] = uigetfile( ...
'*.wav','WAV-files (*.wav)', ...
'Pick a file', ...
'MultiSelect', 'on');
for o = 1:20 % num of fields
[speechIn6,FS6]=wavread(filename(1,o));
speechIn6 = myVAD(speechIn6); 
fMatrix6(1,o) = {mfccf(ncoeff,speechIn6,FS6)}; 
end
Error
??? Error using ==> fileparts at 17
Input must be a row vector of characters.
Error in ==> wavread>open_wav at 193
[pat,nam,ext] = fileparts(file);
Error in ==> wavread at 65
[fid,msg] = open_wav(file);
Error in ==> setTemplates at 74
     [speechIn6,FS6]=wavread(filename(1,o));

Thanks a lot :) Best Regards, Nada Gamal

Answer:

To open Folder and dynmically read files

path='C:\SpeechData\Nada1';

folder = path;

dirListing = dir(folder);

for o = 1:20 % num of fields

for d = 3:length(dirListing)

% loop through the files and open. Note that dir also lists the directories, so you have to check for them.

fileName = fullfile(folder,dirListing(d).name); % use full path because the folder may not be the active path

[speechIn6,FS6]=wavread(fileName);

speechIn6 = myVAD(speechIn6);

fMatrix6(1,o) = {mfccf(ncoeff,speechIn6,FS6)};

I try the codes from mr. Walter Roberson but its said:

Unrecognized function or variable 'filename'.

Error in Untitled (line 2)

filenames = cellstr(filename); %in case only one selected
