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:cMediaNode vol="11000">…
      <p:sndTgt r:embed="rId2" />

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.
