# CoreAudioKit

Add user interfaces to audio units.

## Overview

Core Audio Kit provides views and controllers to use when building Audio Unit user interfaces.

## Topics

### Audio Units

[`AUViewController`](/documentation/CoreAudioKit/AUViewController)

The base class to extend when creating a custom user interface for an audio unit.

[`AUViewControllerBase`](/documentation/CoreAudioKit/AUViewControllerBase)

A type definition that indicates the the platform’s Audio Unit view controller base class.

[`AUAudioUnitViewConfiguration`](/documentation/CoreAudioKit/AUAudioUnitViewConfiguration)

A configuration object that describes how to present the audio unit’s user interface.

[`AUGenericView`](/documentation/CoreAudioKit/AUGenericView)

A view that provides a generic user interface for a Cocoa audio unit.

[`AUPannerView`](/documentation/CoreAudioKit/AUPannerView)

A view that provides a specialized user interface for a Cocoa-based panner audio unit.

[`AUCustomViewPersistentData`](/documentation/CoreAudioKit/AUCustomViewPersistentData)

A protocol that defines the methods an Audio Unit host calls to manage view data.

### Bluetooth Devices

[`CABTLEMIDIWindowController`](/documentation/CoreAudioKit/CABTLEMIDIWindowController)

A window controller that displays nearby Bluetooth-based MIDI peripherals.

[`CABTMIDICentralViewController`](/documentation/CoreAudioKit/CABTMIDICentralViewController)

A view controller that displays nearby Bluetooth-based MIDI peripherals.

[`CABTMIDILocalPeripheralViewController`](/documentation/CoreAudioKit/CABTMIDILocalPeripheralViewController)

A view controller that advertises an iOS device as a Bluetooth-based MIDI peripheral.

### Network Devices

[`CANetworkBrowserWindowController`](/documentation/CoreAudioKit/CANetworkBrowserWindowController)

A window controller that displays available network audio devices.

### Inter-Device Audio

[`CAInterDeviceAudioViewController`](/documentation/CoreAudioKit/CAInterDeviceAudioViewController)

A view controller object that displays iOS devices that support inter-device audio.

### Inter-App Audio

Inter-App Audio is deprecated in iOS 13 and is unavailable when running iPad apps in macOS.

[`CAInterAppAudioSwitcherView`](/documentation/CoreAudioKit/CAInterAppAudioSwitcherView)

A view that provides an audio switcher user interface.

[`CAInterAppAudioTransportView`](/documentation/CoreAudioKit/CAInterAppAudioTransportView)

A view that provides an audio transport user interface.

### Deprecations

[`AUGenericViewInternal`](/documentation/CoreAudioKit/AUGenericViewInternal)

[`AUGenericViewInternalBase`](/documentation/CoreAudioKit/AUGenericViewInternalBase)

### Classes

[`AUAppleCustomViewLoader`](/documentation/CoreAudioKit/AUAppleCustomViewLoader)

[`AUGenericViewController`](/documentation/CoreAudioKit/AUGenericViewController)
