Not sure what "medaian" is but there are functions for mean and median. Did you try either of them? Also, what does "cikis 4" mean?

[y,fs]= audioread('1 normal.mp3');
[y1,fs]= audioread('1 problem.mp3');
plot(y, 'b-', 'LineWidth', 2);
hold on;
plot(y, 'r-', 'LineWidth', 2);
meany  = mean(y(:));
yline(meany, 'Color', 'b', 'LineWidth', 2);
meany1  = mean(y1(:));
yline(meany1, 'Color', 'r', 'LineWidth', 2);

Attach the mp3 files if you need more help.
