How can I simultaneously loop through a folder and process an audio file and text file with the same name?

Good day

I have a folder with 530 files, 265 audio files and 265 text files. Each text file match and audio file and they have the same name for example:

105_1b1_Tc_sc_Meditron.txt and 105_1b1_Tc_sc_Meditron.wav

&&

106_2b1_Pl_mc_LittC2SE.txt and 106_2b1_Pl_mc_LittC2SE.wav

I have written a code and tested it on a single set, but I am unsure how to write the code to loop through the entire folder and make sure that each time a matching set is used. The code I have written:

%% Code starts here

% read in file with textscan

fid = fopen('106_2b1_Pl_mc_LittC2SE.txt');

FC = textscan(fid,'%s','Delimiter','\n');

fclose(fid);

FC = FC{1};

% split all lines

FCsplit = regexp(FC, '(\S*)', 'match');

% columns to extract as double

ind1 = 1:2:3:4;

% prepare result arrays for double and string (as cell array)

D = zeros(length(FCsplit), length(ind1))

% loop over all columns to extract

for n = 1:length(ind1)

    D(:, n) = cellfun(@(x) str2double(x(ind1(n))), FCsplit)

end

[X, Fs]=audioread('106_2b1_Pl_mc_LittC2SE.wav')

L = length(X);

t = [0:L-1]/Fs;

% plot(t,X);

L1 = length(D);

for k = 1:L1

    idx = (D(k,1)<t)  &  (t<D(k,2));
    l = length(X(idx));
    time = t(idx);
    Tw = time(length(time)) - time(1);

    Crackle= D(k,3) 
    Wheeze = D(k,4)

    %sef = feature_extract_f(X(idx), 44100, Tw, Crackle, Wheeze)

end

If possible can someone give me some guidance. I have already looked at How can I process a sequence of files, but the file names vary to much?

I also attached a text file, but unfortunately the .wav format is not supported.

Thank you in advance for your help.

Kind regards

Hi,

Assume there are 265 text file, and 265 audio file are same name.

Therefore, i guess there are in same order of sequence in the folder.

F = dir('*.txt');
C = dir('*.wav');

Put them in the for loop

for i=1:1:length(F)

        %open text file
        fid = fopen(F(i).name);

        % Your own algorithm

        % Open Audio wave
        [X, Fs]=audioread(C(i).name);

       %your own algorithm
end

Help to accept it since it is working for you.
