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 AnnImageObject.Picture value.

The AnnAudioObject class inherits the AnnImageObject class and accesses the common AnnImageObject.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 Automated Annotations - Audio Tab.

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.
