In this tutorial, we will learn how to adjust volume of an externally loaded MP3 file in flash. As we all know, to get this done, we are basically revolving around sound object. The method used to adjust sound volume is setVolume() of sound object. Similarly we can even retrieve the already set volume by getVolume() method, getVolume() returns the sound volume level as an integer from 0 to 100, where 0 is off and 100 is full volume. The default setting is 100.
