Detailed Description

A class responsible for managing audio playback using a playback engine.

Inherits from UST_AudioIOPlaybackBase and overrides audio IO functionality for managing audio playback with a specific playback engine.

Member Function Documentation

DeinitializeAudioIO()

void UST_AudioPlaybackEnginePlayer::DeinitializeAudioIO ( )

overrideprotectedvirtual

Deinitializes the audio IO system for playback.

This function cleans up and stops the playback engine, freeing resources used for audio playback. It overrides the base class method.

Reimplemented from UST_AudioIOPlaybackBase.

GetAudioIOType()

EAudioIOType UST_AudioPlaybackEnginePlayer::GetAudioIOType ( ) const

inlineoverridevirtual

Gets the type of audio I/O for this playback engine player.

Override to return the specific type for playback using the audio engine.

Returns

The type of the audio I/O, typically an EAudioIOType enumeration.

Reimplemented from UST_AudioIOBase.

InitializeAudioIO()

bool UST_AudioPlaybackEnginePlayer::InitializeAudioIO ( )

overrideprotectedvirtual

Initializes the audio IO system for playback with the engine.

This function sets up the necessary configuration and starts the playback engine for audio playback. It overrides the base class method.

Returns

true if initialization was successful; false otherwise.

Reimplemented from UST_AudioIOBase.
