How to specify path name in sprintf?

I have a folder specified by the path D:\BTP\0 (1)\0 . This contains wave file ranging from 0 to 59 and I need to read each of them using the command

for m=0:59
  filename = sprintf('%d.wav',m); 
 [s,fs] = audioread(filename);
end

I need to specify file name inside sprintf command. How do I do so?

You can do this through string concatenation:

mypath = 'D:\BTP\0 (1)\';
for m=0:59
filename = [mypath num2str(m) '.wav'];
 [s,fs] = audioread(filename);
end

If it needs to be inside sprintf, you can use:

mypath = 'D:\\BTP\\0 (1)\\';
filename = sprintf([mypath '%d.wav'],m);

where the double slash, \\, generates the single \ in this context.

Thank You man. Got it done.

With sprintf:

mypath = 'D:\BTP\0 (1)\';

filename = sprintf('%s%d.wav', mypath, m);

However I recommend instead

mypath = fullfile('D:', 'BTP', '0 (1)');

filename = fullfile(mypath, sprintf('%d.wav', m));

I also wanted to ask one more: I have wave files with names like:

00 01 02 03 04 .... and so on till 59. How do I read them using sprintf? The first digit of the filename specifies speaker id and the second digit specifies utterence id .

 filename = fullfile(mypath, sprintf('%02d.wav', m));
