19.5.9 audio (Audio)
This element is used to include audio during an animation. This element specifies that this node within the animation tree triggers the playback of an audio file; the actual audio file used is specified by the sndTgt element (§19.5.70).
[Example: Consider adding applause sound to an animation sequence. The audio element is used as follows:
<p:cTn …>
<p:stCondLst>…</p:stCondLst>
<p:childTnLst>…</p:childTnLst>
<p:subTnLst>
<p:audio>
<p:cMediaNode vol="11000">…
<p:tgtEl>
<p:sndTgt r:embed="rId2" />
</p:tgtEl>
</p:cMediaNode>
</p:audio>
</p:subTnLst>
</p:cTn>
The audio element specifies the location of the audio playback within the animation; its child sndTgt element specifies that the audio to be played is the target of the relationship with ID rId2.
