Hello Sobel,

For this purpose, you can use sprintf() function. This function will use an integer to generate the name of the file. Here is an example of the same:

sprintf('%d.wav', i);

This line of code can be wrapped inside a for loop to generate multiple such names depending on i.

For more information on sprintf() please follow this link: https://www.mathworks.com/help/matlab/ref/sprintf.html

I hope this helps!
