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!
