20.1.3.7 wavAudioFile

This element specifies the existence of an audio WAV file. This element is specified within the non-visual properties of an object. The audio shall be attached to an object as this is how it is represented within the document. The actual playing of the audio however is done within the timing node list that is specified under the timing element.

[Example: Consider the following picture object that has an audio WAV file attached to it.

<p:pic>
  <p:nvPicPr>
    <p:cNvPr id="7" name="Rectangle 6">
      <a:hlinkClick r:id="" action="ppaction://media"/>
    </p:cNvPr>
    <p:cNvPicPr>
      <a:picLocks noRot="1"/>
    </p:cNvPicPr>
    <p:nvPr>
      <a:wavAudioFile r:embed="rId2"/>
    </p:nvPr>
  </p:nvPicPr>
  …
</p:pic>

In the above example, we see that there is a single wavAudioFile element attached to this picture. This picture is placed within the document just as a normal picture or shape would be. The id of this picture, namely 7 in this case, is used to refer to this wavAudioFile element from within the timing node list. The Embedded relationship id is used to retrieve the actual audio file for playback purposes. end example]

[Note: This element is generally used for the purposes of embedding audio files within the document. For linking to generic audio files the audioFile element should be used. end note]
