We are going to create a simple singleton class and put all the code related to the audio playback into it.
Note
Although we could play any sound effect with just a single line of code by using OALSimpleAudio, we are going to create a special class called AudioManager. This will allow us to keep the audio playback code separate from the rest of our code.
