OTAudioDeviceManager Class Reference

Inherits from	NSObject
Declared in	OTAudioKit.h

Overview

Use the AudioDeviceManager to set a custom audio device to be used by the app. The audio device manages access to the audio capturing and rendering hardware.

You can only define a single audio capture source and rendering target for the entire process. You cannot set these individually for each publisher and subscriber. You can, however, set the audio bitrate for a published stream by setting the [OTPublisherKitSettings audioBitrate] property.

`+ setAudioDevice:`

Sets the audio device to be used.

+ (void)setAudioDevice:(_Nullable id<OTAudioDevice>)device

Parameters

`device`	The OTAudioDevice interface implementation. This object is retained.

Discussion

You must call this method before you connect to a session. Additionally, this is a global operation that must persist throughout the lifetime of an application.

If you do not call this method, the app uses the iOS device’s microphone and speaker.

OTAudioKit.h

`+ currentAudioDevice`

Gets the OTAudioDevice instance.

+ (_Nullable id<OTAudioDevice>)currentAudioDevice

Return Value

id The OTAudioDevice implementation.

Declared In

OTAudioKit.h

`+ currentAudioSessionManager`

Gets the OTAudioSessionManager instance, if the current audio device supports it.

+ (_Nullable id<OTAudioSessionManager>)currentAudioSessionManager

Return Value

id The OTAudioSessionManager implementation, or nil if unsupported.

Discussion

This returns the same instance as currentAudioDevice if it conforms to the OTAudioSessionManager protocol. Otherwise, returns nil.

Note: Currently only the default audio device supports this protocol.
