Detailed Description

A class responsible for managing audio playback with noise data.

Inherits from UST_AudioIOPlaybackBase and overrides audio I/O functionality for handling audio playback from noise data.

Member Function Documentation

◆ DeinitializeAudioIO()

void UST_AudioPlaybackNoise::DeinitializeAudioIO ( )

overrideprotectedvirtual

Deinitializes the audio I/O system for noise playback.

This function ensures proper cleanup of any resources used by the playback system.

Reimplemented from UST_AudioIOPlaybackBase.

◆ GetAudioIOType()

EAudioIOType UST_AudioPlaybackNoise::GetAudioIOType ( ) const

inlineoverridevirtual

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

Override to return the specific type for playback. This will indicate how the noise is being played back and processed.

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

Reimplemented from UST_AudioIOBase.

◆ InitializeAudioIO()

bool UST_AudioPlaybackNoise::InitializeAudioIO ( )

overrideprotectedvirtual

Initializes the audio I/O system for noise playback.

This function sets up the necessary configuration for noise audio playback. It overrides the base class method to ensure proper setup for playback.

Returns: true if initialization was successful; false otherwise.

Reimplemented from UST_AudioIOBase.

◆ MA_PlaybackNoiseCallBack()

void UST_AudioPlaybackNoise::MA_PlaybackNoiseCallBack	(	ma_device *	pDevice,
		void *	pOutput,
		const void *	pInput,
		ma_uint32	frameCount )

static

The callback function for audio playback of noise data.

This function is called during the audio playback process, providing the necessary data to the audio device for output.

Parameters

pDevice	The audio device to which the output is being sent.
pOutput	Pointer to the output buffer for audio data.
pInput	Pointer to the input buffer, if needed.
frameCount	The number of frames to process.

Member Data Documentation

◆ Noise

ma_noise* UST_AudioPlaybackNoise::Noise = nullptr

protected

The noise used for audio playback.

This pointer holds the noise data to be used for playback.

◆ pAllocationCallbacks

ma_allocation_callbacks* UST_AudioPlaybackNoise::pAllocationCallbacks = nullptr

protected

Custom memory routine.

This pointer holds the noise data to be used for playback.
