# PHASEPushStreamNode

An audio stream you manage to provide a sound buffer data.

## Declaration

```swift
class PHASEPushStreamNode
```

## Overview

Overview A sound event’s pushStreamNodes dictionary populates with an instance of this class when PHASE invokes a  PHASEPushStreamNodeDefinition in your event node tree. Your app provides the audio data that the sound event plays by calling one or more of this class’s buffer-scheduling functions, for example, scheduleBuffer(buffer:).
