I have been writing a SoundManager class to easily manipulate music and sounds in my Starling game and I thought I would share it with you, in the hope that you may find it useful for your projects.
Find it on Gist:
together with usage examples (scroll down to the bottom of the code in that page).
If you have suggestions for improvements please don't hesitate to write a comment either here or on Gist.
N.B. This class is based on the SoundManager class of the Citrus game engine, which I simplified and added some tweening methods to, taking advantage of Starling's tweening functionalities.
