# PHASEGeneratorNodeDefinition

A base class for nodes that provide audio data to generate sound.

## Declaration

```swift
class PHASEGeneratorNodeDefinition
```

## Overview

Overview This class encapsulates shared logic for subclasses that provide audio data to a mixer for sound output, namely PHASESamplerNodeDefinition and PHASEPushStreamNodeDefinition.
