Detailed Description

AST_N_VisFrequencyBuffer is a derived class from AST_VisNiagaraBase. It is responsible for handling frequency buffer data in the context of audio visualization. The class sets constant and dynamic parameters, manages audio I/O status changes, and processes frequency bands.

Member Function Documentation

BeginPlay()

void AST_N_VisFrequencyBuffer::BeginPlay ( )

overrideprotectedvirtual

Called when the game begins or when the actor is spawned. This function is used to initialize any necessary components or perform setup operations.

Reimplemented from AST_VisBase.

OnAudioIOStatusChanged_Implementation()

void AST_N_VisFrequencyBuffer::OnAudioIOStatusChanged_Implementation ( bool bIsActive, FIntPoint IOId )

overrideprotectedvirtual

Called when the audio I/O status changes.

Parameters

bIsActive	Indicates if the audio I/O is active.
IOId	The identifier of the I/O operation whose status has changed.

OnFrequencyBandsReady_Implementation()

void AST_N_VisFrequencyBuffer::OnFrequencyBandsReady_Implementation ( const TArray< float > & FrequencyBands, int32 NumFrequencyBands, FIntPoint IOId )

overrideprotectedvirtual

Called when the frequency bands are ready to be processed.

Parameters

FrequencyBands	The array of frequency band data.
NumFrequencyBands	The number of frequency bands.
IOId	The identifier of the I/O operation associated with the frequency data.

SetConstantParameters()

bool AST_N_VisFrequencyBuffer::SetConstantParameters ( )

overrideprotectedvirtual

Sets the constant parameters for the frequency buffer visualization.

Returns

Returns true if the parameters were successfully set, false otherwise.

Reimplemented from AST_VisBase.

SetDynamicParameters()

bool AST_N_VisFrequencyBuffer::SetDynamicParameters ( )

overrideprotectedvirtual

Sets the dynamic parameters for the frequency buffer visualization.

Returns

Returns true if the parameters were successfully set, false otherwise.

Reimplemented from AST_VisBase.

Member Data Documentation
