Chapter 7. Working with Audio
You can’t physically manipulate audio with HTML5 Canvas as directly as
you can video, but many canvas applications can use that extra dimension of
sound. Audio is represented by the HTMLAudioElement object
manipulated through JavaScript and by the <audio> tag in HTML5. There is no Canvas API
for audio nor, really, is one necessary. However, there are many ways that
you might want to use audio with HTML5 Canvas. As you will see, the HTMLAudioElement has some limitations and can be
frustrating. However, with developments like the Web Audio API on the
horizon, the outlook for using audio with the HTML5 Canvas looks brighter
every day.
