# AVAudioCompressedBuffer

An object that represents an audio buffer that you use for compressed audio formats.

## Declaration

```swift
class AVAudioCompressedBuffer
```

## Topics

### Creating an Audio Buffer

- [init(format:packetCapacity:)](avfaudio/avaudiocompressedbuffer/init(format:packetcapacity:).md)
- [init(format:packetCapacity:maximumPacketSize:)](avfaudio/avaudiocompressedbuffer/init(format:packetcapacity:maximumpacketsize:).md)
