Play/pause button for audio

[greg...@sunyit.edu]

I'm working on a project for a Hypertext class, and I have an audio file that I'd like the listener to be able to play by clicking on a single "play/pause" button. I don't want the audio file to be visible. I'm not sure how to do this- any help would be appreciated!

So far I have

<$button set="$:/state/SampleReveal1" setTo="show">Show Audio</$button>

<$button set="$:/state/SampleReveal1" setTo="hide">Hide Audio</$button>

<$reveal type="match" state="$:/state/SampleReveal1" text="show">

{{!!pronunciation}}

</$reveal>

And in the "pronunciation" field

<audio controls id="demo" src="http://ia902604.us.archive.org/10/items/the_911_report_librivox/911report_01.mp3#t=365,367"/>

Thanks!
