If you open the app from that example in MATLAB, it defines a private property named AudioFileName (line 29.)

Where in your app do you define a function, method, or property by that name?

Opening the Code View for your app and searching, I see only six places where the identifier AudioFileName occurs and all of those look like attempts to reference that property. Nowhere in your code did you define that property.
