Example

This example creates a new audio object at location 100, 200 and with dimensions of 400 x 600 and then adds it to a container.

Visual BasicCopy Code
Private Sub AnnAudioObject_AnnAudioObject(ByVal container As AnnContainer, ByVal waveFileName As String)
   Dim audio As AnnAudioObject = New AnnAudioObject()
   audio.Bounds = New AnnRectangle(100, 200, 400, 600, AnnUnit.Pixel)
   audio.FileName = waveFileName
   container.Objects.Add(audio)
   ' play the audio to test it
   If (audio.CanPlay) Then
      audio.Play()
   End If
End Sub
C#Copy Code
private void AnnAudioObject_AnnAudioObject(AnnContainer container, string waveFileName) 
{ 
   AnnAudioObject audio = new AnnAudioObject(); 
   audio.Bounds = new AnnRectangle(100, 200, 400, 600, AnnUnit.Pixel); 
   audio.FileName = waveFileName; 
   container.Objects.Add(audio); 
   // play the audio to test it 
   if((audio.CanPlay)) 
      audio.Play(); 
}

Remarks

The audio annotation object is a scaled image that can be activated to play an audio (WAV) clip. The WAV file path is stored in the FileName property, so the WAV data itself is not stored in this object, only the physical path. In automation mode, when this audio object is clicked, the framework will try to locate and then play the WAV file stored in FileName. This object will use the default image of an audio speaker. To change this default image, change the Picture value.

The AnnAudioObject class inherits the the AnnImageObject class and accesses the common Picture property mentioned above through this inheritance.

For more information about the audio annotation object refer to AnnAudioObject. For more information about the automated annotation audio object, refer to Annotation Objects - Automated Features and Audio Tab.
