This is the Core of the sound and music in orxonox.

== library ==
First of all: We use [http://www.openal.org openAL] for rendering of Music and Sound. This is because first of all it suits our framework the best (eg. PNode) and secondly because it is the only usefull 3D-sound-Engine that is cross-platform compatible

== usage ==
openAL is very easy to use, and the interface is even easier

Orxonox-SoundEngine-openAL has three classes:
  * SoundBuffers: Buffers that alocate the memory for playing sound. (they only hold the data, but cannot play)
  * SoundSources: Play the Buffers at a certain position
  * Listeners: Listen to the music from some position (usually camera)

Now orxonox implements initialisation of the SoundEngine for itself, so you do not have to worry about it. But there are some interessting functions in it:
{{{
  SoundSource* createSource(const char* fileName, PNode* sourceNode);
}}}

used like this:

{{{
SoundSource* testSound = SoundEngine::getInstance()->createSource("sound/somesound.wav", this->localPlayer);
}}}
this automatically binds the Buffer read in from "sound/somesond.wav" onto the localPlayer

alternatively do something like:
{{{
SoundBuffer* newBuf = (SoundBuffer*)ResourceManager::getInstance()->load("file.wav", WAV);
SoundSource* source = (newBuf, this->localPlayer);
}}}
this does the same thing, but is not really used, because one can flush the Buffers via the SoundEngine.

== SoundSources ==
important functions for SoundSources
{{{
  void play();
  void stop();
  void pause();
  void rewind();
}}}

less important, but not to forget:
{{{
void setRolloffFactor(ALfloat rolloffFactor);
}}}

And thats about it.
