AVAudioEngine objects contain instances of various AVAudioNode subclasses. This base class provides certain common functionality.
Nodes have input and output busses, which can be thought of as connection points. For example, an effect typically has one input bus and one output bus. A mixer typically has multiple input busses and one output bus.
Busses have formats, expressed in terms of sample rate and channel count. When making connections between nodes, often the format must match exactly. However, there are exceptions such as the AVAudioMixerNode and AVAudioOutputNode classes.
Nodes do not currently provide useful functionality until attached to an engine.
This is an abstract class. You can't create an instance, but you can get one from various plugin functions.
