[ISO/IEC 29500-1 1st Edition]

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.
