They would typically be mixers of streams, audio effects or analysis. The Sound Processing functions are those which basically work on the source as a continuous audio stream. The Visualization functions are experimental ones that let you visualize in real-time some aspects of the audio stream. The Output functions are those which take a source and register it for being streamed to the outside (file, soundcard, audio server, etc.).
The Input functions are those which build elementary sources (playing files, synthesizing sound, etc.). The Source / … categories contain all functions that return sources.
