Class ChebyshevBandPassRejectBlock

Namespace

VisioForge.Core.MediaBlocks.AudioProcessing

Assembly

VisioForge.Core.dll

Chebyshev band pass and band reject audio filter block for precise frequency domain processing. This block implements high-quality Chebyshev filters that can operate in band-pass or band-reject modes to selectively allow or remove specific frequency ranges from audio signals. Chebyshev filters provide steeper roll-off characteristics compared to Butterworth filters, making them ideal for applications requiring precise frequency separation. The block supports configurable ripple, cutoff frequencies, and filter order for optimal audio filtering performance. Essential for audio cleanup, noise reduction, frequency isolation, and professional audio processing applications. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

Constructors

ChebyshevBandPassRejectBlock(ChebyshevBandPassRejectAudioEffect)

Initializes a new instance of the VisioForge.Core.MediaBlocks.AudioProcessing.ChebyshevBandPassRejectBlock class with specified Chebyshev filter settings for band-pass or band-reject operation.

public ChebyshevBandPassRejectBlock(ChebyshevBandPassRejectAudioEffect settings)

Parameters

settings ChebyshevBandPassRejectAudioEffect

The Chebyshev filter configuration settings defining mode, cutoff frequencies, and filter characteristics.

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[]

Settings

Gets or sets the Chebyshev band-pass/reject filter settings. Contains configuration for filter mode (band-pass or band-reject), lower and upper cutoff frequencies, filter order, ripple amount, and other parameters for precise frequency domain control.

public ChebyshevBandPassRejectAudioEffect Settings { get; set; }

Property Value

ChebyshevBandPassRejectAudioEffect

Type

Gets the type.

public override MediaBlockType Type { get; }

Property Value

MediaBlockType

Methods

Build()

Constructs and initializes the Chebyshev band-pass/reject filter and its associated GStreamer elements. This method creates the filter with the specified settings, establishes input and output pads, and prepares the block for frequency domain audio processing with steep roll-off characteristics.

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 Chebyshev band-pass/reject filter 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 Chebyshev band-pass/reject filter element.

public BaseElement GetCore()

Returns

BaseElement

The BaseElement wrapper instance that encapsulates the GStreamer Chebyshev filter.

GetElement()

Gets the underlying GStreamer element that performs the Chebyshev band-pass/reject filtering.

public Element GetElement()

Returns

Element

The GStreamer Element instance representing the Chebyshev 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 Chebyshev band-pass/reject filter 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.
