I have Emo-DB databse containing file name wav files with file name as following
1 03a01Ab.wav
2 03a01Eb.wav
3 03a01Fa.wav
4 03a01Lb.wav
5 03a01Nc.wav
6 03a01Tc.wav
7 03a01Wa.wav
8 08a01Aa.wav
9 08a01Ab.wav
10 08a01Ec.wav
11 08a01Fd.wav
12 08a01Lc.wav
13 08a01Na.wav
14 08a01Td.wav
15 08a01Wa.wav
16 08a01Wc.wav
17 09a01Aa.wav
18 09a01Ea.wav
19 09a01Fa.wav
20 09a01Lc.wav
21 09a01Nb.wav
Here
- # Positions 1-2: number of speaker
- # Positions 3-5: code for textspoken
- # Position 6: emotion
- # Position 7: if there are more than two versions these are numbered a, b, c ....
Now how do I read all these files using using audioread in a single loop. I tried the following code but it doesn't work:
for i=0
for j=0:0
for k=0:0
fid = fopen(filename,'a');
file =sprintf('%s%d%s%d%d.wav', 'D:\BTP\0 (1)\', i,'\',j,k);
[s, fs] = audioread(file);
end
end
end

What is not working? You did not give error information. Your for-loops are also incorrect. For a possible solution see the answer below.

Instead of trying to create file names yourself, uou can use dir command to get list of all files in the current folder. Then use the list to read all files with an extension of '.wav'.
files = dir;
count = 0;
for i = files' if length(i.name) > 4 && i.name(end-3:end) == ".wav" % only read file if filename is greater then four and extension is '.wav' count = count+1; [f{count} fs{count}] = audioread(i.name); end end
This script will load all data in cell arrays f and fs.

Or easier:
FileList = dir('D:\BTP\0 (1)\*.wav'); for File = FileList' count = count + 1; [f{count}, fs{count}] = audioread(File.name); end

You can use the fileDatastore with the audioread as the Custom function.
