SoundBuffers and SoundSources are stored in in a ```Map``` so they can be retrieved by an identifier. Although a `SoundSource` will be bound always only toa a single `SoundBuffer` we do not need to create a sound soruce for ach possible sound. In fact, we can have a few sound sources depending on their characteristics, for example if they are relative or not, or their position, and change the buffer which they are bound to dynamically.
