try the simple code below to see what i mean

I did try the code, but I don't understand what you expect to happen. Can you give a more concrete example? What should I expect to happen if I first enter 5, then enter 3, for example?

Here are some suggestions:

• Use warnings and eliminate the warning messages you get.
• Use perltidy to neaten your indentation to make your code easier to follow and debug.
• Localize the scope of as many variables as possible. For example, pass $repeats as a parameter to your sub: make_wav($repeats);
