<p>A game isn’t complete without sound. Most games play some cool
background music to set the mood and have many sound effects to play
when events happen. The <code>(chickadee audio)</code> module provides a
robust audio API backed by the OpenAL 3D audio system.

<p>The basics of playing audio are very simple. Just load an audio file
in the load hook (or anywhere else once the game loop is running) and
play it!
