# PHASEPushStreamNodeDefinition

A node that plays a sequence of audio buffers.

## Declaration

```swift
class PHASEPushStreamNodeDefinition
```

## Overview

Overview Use this node to create sound events for a piecemeal audio source, for example, an audio stream that your app accesses over the network or loads from a memory-mapped file on disk. note: To create a sound event for fully-loaded audio data instead, use PHASESamplerNodeDefinition.
