The waveform played is not within the code, it looks like the code instructs a laptop to play a note from .wav files.
The waveform is stored in the laptop that the program is associated with.
You could run an audio software package on the laptop and examine the .wav files directly.
 
If the processor is fast enough you could use the analogue to digital input and use the serial plot function within the arduino Ide, you'd need to do some fudging to slow down the sample rate so's not to make a display that scrolls too fast.
