# AVAudioSession.Mode

Audio session mode identifiers.

struct Mode

## Overview

While categories set the base behaviors for your app, you use modes to assign specialized behavior to an audio session category.

> Important:
> Specifying a mode that the audio session category doesn’t support, such as setting the ``doc://com.apple.avfaudio/documentation/AVFAudio/AVAudioSession/Mode-swift.struct/gameChat`` mode for the ``doc://com.apple.avfaudio/documentation/AVFAudio/AVAudioSession/Category-swift.struct/multiRoute`` category, results in the audio session using the ``doc://com.apple.avfaudio/documentation/AVFAudio/AVAudioSession/Mode-swift.struct/default`` mode behavior.

## Topics

### Creating a Mode

[`init(rawValue:)`](/documentation/AVFAudio/AVAudioSession/Mode-swift.struct/init(rawValue:))

Creates a new instance with the raw value you specify.

### Getting Standard Session Modes

[`default`](/documentation/AVFAudio/AVAudioSession/Mode-swift.struct/default)

The default audio session mode.

[`dualRoute`](/documentation/AVFAudio/AVAudioSession/Mode-swift.struct/dualRoute)

A mode that provides simultaneous use of the built-in microphone/speaker and a secondary audio device that supports input and output.

[`gameChat`](/documentation/AVFAudio/AVAudioSession/Mode-swift.struct/gameChat)

A mode that the GameKit framework sets on behalf of an application that uses GameKit’s voice chat service.

[`measurement`](/documentation/AVFAudio/AVAudioSession/Mode-swift.struct/measurement)

A mode that indicates that your app is performing measurement of audio input or output.

[`moviePlayback`](/documentation/AVFAudio/AVAudioSession/Mode-swift.struct/moviePlayback)

A mode that indicates that your app is playing back movie content.

[`shortFormVideo`](/documentation/AVFAudio/AVAudioSession/Mode-swift.struct/shortFormVideo)

Appropriate for applications playing short-form video content.

[`spokenAudio`](/documentation/AVFAudio/AVAudioSession/Mode-swift.struct/spokenAudio)

A mode used for continuous spoken audio to pause the audio when another app plays a short audio prompt.

[`videoChat`](/documentation/AVFAudio/AVAudioSession/Mode-swift.struct/videoChat)

A mode that indicates that your app is engaging in online video conferencing.

[`videoRecording`](/documentation/AVFAudio/AVAudioSession/Mode-swift.struct/videoRecording)

A mode that indicates that your app is recording a movie.

[`voiceChat`](/documentation/AVFAudio/AVAudioSession/Mode-swift.struct/voiceChat)

A mode that indicates that your app is performing two-way voice communication, such as using Voice over Internet Protocol (VoIP).

[`voicePrompt`](/documentation/AVFAudio/AVAudioSession/Mode-swift.struct/voicePrompt)

A mode that indicates that your app plays audio using text-to-speech.
