Detailed Description

A class responsible for capturing audio in a loopback mode.

Inherits from UST_AudioIOCaptureBase and overrides audio IO functionality for capturing audio in a loopback configuration.

Member Function Documentation

GetAudioIOType()

EAudioIOType UST_AudioCaptureLoopback::GetAudioIOType ( ) const

inlineoverridevirtual

Gets the type of audio I/O for this capture device.

Override to return the specific type for loopback audio capture.

Returns

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

Reimplemented from UST_AudioIOBase.

InitializeAudioIO()

bool UST_AudioCaptureLoopback::InitializeAudioIO ( )

overrideprotectedvirtual

Initializes the audio IO system for loopback audio capture.

This function sets up the necessary configuration and starts the loopback capture process. It overrides the base class method.

Returns

true if initialization was successful; false otherwise.

Reimplemented from UST_AudioIOBase.
