In my GUI, I have loaded an audio file ( .wav ) into the variable storedStructure, and saved it in the handles structure - handles.str1
Now, i would like to use 2 data cursors to dynamically alter the audio playing length. For example, if the length of the audio is 5 seconds, if I were to choose 2 cursors at 2 seconds and 4 seconds, it would play only that part of the audio.
I need to put this code right away in my .m file for my GUI.

Is there a reason why you need to use data cursors instead of (for example) ginput() ?
What is the data cursor to be applied against? Data cursors require a graph, but you have not indicated anything as being graphed. Are you graphing the signal level, or are you graphing the time?
Why not use a couple of sliders?

Correction:
plot(handles.Audio, first_samp : nsamp, sig(first_samp:end, :));
