I am getting parse error at the marked bracket, I don't know why!

Please copy the exact error message you get.

[Guillaume]

Please post (or attach as a m file) the exact code you're using. Without any modification. Also post the full text of the error message.

You've given us conflicting versions of your code. With this particular error, the problem is from what comes before the [.

[sp1,fs1] = audioread('F:\Moodle\Summer18\sync porject\iitb recordings\01_SPK1_05_06_2017-09.wav');

There should be no stars, in the first place. And this line should be copied above your function audio not, after the function.

[Abhiraj Kanse]

stars are just for showing where the error was popping, if i copy it after the before the function then it shows error on the function. I am a beginner, I think the error here is in my understanding of using functions in Matlab.

[Abhiraj Kanse]

[sp1,fs1] = audioread('F:\Moodle\Summer18\sync porject\iitb recordings\01_SPK1_05_06_2017-09.wav');    
[ar1,fs4] = audioread('F:\Moodle\Summer18\sync porject\iitb recordings\04_ARRAY1_05_06_2017-09.wav');
ar11 = ar1.*(100);

function [fdly,tdly] = delaycalc(sig1,sig2)
    i = 1;
    j = 1;
    fdly = zeros(1,266);
    tdly = zeros(1,266);
    while (i <= 12768000)
        a = sig1(i:48000);
        b = sig2(i:48000);
        [cor,lag] = xcorr(a,b,'coeff');
        [~,Il] = max(abs(cor));
        lagdly = lag(Il);
        tmdly = lagdly/48000;
        i = i+48000;
        j = j+1;
        display(tmdly)
        display(lagdly)
    end

Now it shows this error: Line 5: FUNCTION keyword use is invalid here. This might cause later message about END. Line 5: Parse error at ']': usage might be invalid MATLAB syntax

Line 5: Parse error at ')': usage might be invalid MATLAB syntax

Save this code first, defualt this will be saved on the name delaycalc. Save this in some folder.

function [fdly,tdly] = delaycalc(sig1,sig2)
    i = 1;
    j = 1;
    fdly = zeros(1,266);
    tdly = zeros(1,266);
    while (i <= 12768000)
        a = sig1(i:48000);
        b = sig2(i:48000);
        [cor,lag] = xcorr(a,b,'coeff');
        [~,Il] = max(abs(cor));
        lagdly = lag(Il);
        tmdly = lagdly/48000;
        i = i+48000;
        j = j+1;
        display(tmdly)
        display(lagdly)
    end

And then, change the path, and go to that folder. Now, you can call that function.

[sp1,fs1] = audioread('F:\Moodle\Summer18\sync porject\iitb recordings\01_SPK1_05_06_2017-09.wav');    
[fdly,tdly] = delaycalc(sp1,fs1)
