Introducing Sound Objects

Sound objects use either the attachSound or the loadSound method to incorporate sound into your movie. This will be explained in more detail shortly. The attachSound method has two parts: the object and the internally linked sound. When the object is called, it attaches the sound (which resides in the library) that was linked to the object when the sound object was defined. Sound objects that use the attachSound method are embed in the SWF.

Sound objects that use the loadSound method also have two parts: the object and the URL to the external sound to be loaded. When the object is called, the external sound loads into the movie. Sound objects that use the loadSound method can be loaded either as events or as streaming. Event sounds must load completely before they play, while streaming sounds begin to play as soon as enough data has loaded to start the sound.

Sound objects have methods, properties and event handlers. The following table lists these items.


  • attachSound()
  • getBytesLoaded()
  • getBytesTotal()
  • getPan()
  • getTransform()
  • getVolume()
