Class AudioRNNoiseBlock

Namespace
VisioForge.Core.MediaBlocks.AudioProcessing
Assembly
VisioForge.Core.dll

RNN-based audio noise reduction block using audiornnoise from rsaudiofx plugin. Uses a recurrent neural network to intelligently remove noise from audio streams while preserving speech and other desired audio content. Features voice activity detection for optimized noise reduction performance. Essential for cleaning audio recordings, live streams, and communication applications. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

AudioRNNoiseBlock()

Initializes a new instance of the VisioForge.Core.MediaBlocks.AudioProcessing.AudioRNNoiseBlock class with default noise reduction settings.

public AudioRNNoiseBlock()

Properties

Input

Gets the input.

public override MediaBlockPad Input { get; }

Property Value

MediaBlockPad

Inputs

Gets the inputs.

public override MediaBlockPad[] Inputs { get; }

Property Value

MediaBlockPad[]

Output

Gets the output.

public override MediaBlockPad Output { get; }

Property Value

MediaBlockPad

Outputs

Gets the outputs.

public override MediaBlockPad[] Outputs { get; }

Property Value

MediaBlockPad[]

Type

Gets the type.

public override MediaBlockType Type { get; }

Property Value

MediaBlockType

VadThreshold

Gets or sets the voice activity detection threshold. Valid range: 0.0 to 1.0. Default: 0.0. Higher values make the algorithm more sensitive to voice activity, which can help preserve speech quality while reducing noise.

public float VadThreshold { get; set; }

Property Value

float

Methods

Build()

Constructs and initializes the audio RNN noise reduction filter and its associated GStreamer elements. This method creates the filter with the specified noise reduction parameters, establishes input and output pads, and prepares the block for reducing noise using recurrent neural network algorithms.

public override bool Build()

Returns

bool

true if the filter was successfully built and configured; false if initialization failed.

CleanUp()

Releases all resources and performs cleanup operations for this audio RNN noise reduction block. This method disposes of the GStreamer elements and resets the build state.

public void CleanUp()

Dispose(bool)

Releases unmanaged and - optionally - managed resources.

protected override void Dispose(bool disposing)

Parameters

disposing bool

true to release both managed and unmanaged resources; false to release only unmanaged resources.

GetCore()

Gets the core BaseElement wrapper that provides additional functionality around the GStreamer audio RNN noise reduction filter element.

public BaseElement GetCore()

Returns

BaseElement

The BaseElement wrapper instance that encapsulates the GStreamer audio RNN noise reduction filter.

GetElement()

Gets the underlying GStreamer element that performs the noise reduction processing.

public Element GetElement()

Returns

Element

The GStreamer Element instance representing the audio RNN noise reduction filter.

IsAvailable()

Determines whether this media block is available. Correct NuGet SDK redist should be included into your project.

public static bool IsAvailable()

Returns

bool

true if this media block is available; otherwise, false.

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

Associates this audio RNN noise reduction block with a pipeline and initializes its internal context. This method is called internally when the block is added to a pipeline.

void IMediaBlockInternals.SetContext(MediaBlocksPipeline pipeline)

Parameters

pipeline MediaBlocksPipeline

The MediaBlocksPipeline instance that will manage this block.
