Sound has become a key addition to many Flash projects: offline and online. In many cases, integrating sound can actually amplify the final results of a project. However, in many other cases sound should not even be a topic for discussion. Whatever your case may be, I am going to quickly go over how to load an external sound file using AS3.
Thanks to the Adobe Gods for making the lives of so many Flash developers much less complicated when dealing with XML Data. XML and AS2 just did not get along very well.
In AS3, the XML libraries have been completely overhauled. These new changes provide a much more seamless XML integration that is based on the web standards of E4X.
