Most objects of irrKlang are derived from IRefCounted, and so they are reference counted.

A simple example:
If you want to play a sound, you may want to call the method
ISoundEngine::play2D. You call
ISound* mysound = engine->play2D("foobar.mp3", false, false true);
If you no longer need the sound interface, call mysound->drop(). The
sound may still play on after this because the engine still has a reference
to that sound, but you can be sure that it's memory will be released as soon
the sound is no longer used.
If you want to add a sound source, you may want to call a method
ISoundEngine::addSoundSourceFromFile. You do this like
ISoundSource* mysource = engine->addSoundSourceFromFile("example.jpg");
You will not have to drop the pointer to the source, because
sound sources are managed by the engine (it will live as long as the sound engine) and
