Playing the Sound
Finally, we get to the point where we can play a sound inside our canvasApp() function. Be-
cause we preloaded the sound originally outside the context of this function into a variable
with a global scope, we just need to call the play() function audioElement to start playing
the sound:
audioElement . play ();
Figure 7-4 shows what this Canvas application will look like when executed in an
HTML5-compliant web browser. (Notice that we have left the display of the audio properties
in this application.)
