# AVAudioConverter

An object that converts streams of audio between formats.

## Declaration

```swift
class AVAudioConverter
```

## Overview

Overview The audio converter class transforms audio between file formats and audio encodings. Supported transformations include: PCM float, integer, or bit depth conversions PCM sample rate conversion PCM interleaving and deinterleaving Encoding PCM to compressed formats Decoding compressed formats to PCM A single audio converter instance may perform more than one of the above transformations.
