Added SoundEmitter::getDecodedLength and SoundEmitter::getDuration. The getDuration function will allow a timer to be registered to fire after the sound has been played. This is not a callback as requested but it does provide the functionality if required. I will be committing an example of it in the shooter demo shortly. [t:346]
