Remarks
This class makes use of IEditableObject to enable batching of property change requests. For example, when a track changes, the application may want to update several pieces of metadata all at once, such as track name, artist, album, and so on.
Once the track has been created using one of the AudioTrack constructors, then the BeginEdit()()() and EndEdit()()() methods must be used to update the object.
