Member Function Documentation

◆ OnAudioIOStatusChanged_Implementation()

void AST_N_VisBeatDetection::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.

◆ OnBeatDetected_Implementation()

void AST_N_VisBeatDetection::OnBeatDetected_Implementation	(	const TArray< float > &	Beats,
		const TArray< FChannelBeatDetection > &	BeatDetectionForChannel,
		FIntPoint	IOId )

overrideprotectedvirtual

Called when beats are detected.

Parameters

Beats	An array of detected beat values.
BeatDetectionForChannel	An array of channels and if a beat was detected and the current BPM.
IOId	The identifier of the I/O operation associated with the beats.

◆ SetConstantParameters()

bool AST_N_VisBeatDetection::SetConstantParameters ( )

overrideprotectedvirtual

Sets the constant parameters for the beat detection visualization.

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

Reimplemented from AST_VisBase.
