Detailed Description

An AudioNode that mixes a sequence of clips of other nodes.

This node takes a set of input AudioNodes with associated start + end times, and mixes together their output.

It initialises and releases its inputs as required according to its current play position.

Member Function Documentation

addInput()

void tracktion::engine::CombiningAudioNode::addInput	(	legacy::EditTimeRange	time,
		AudioNode *	inputNode
	)

Adds an input node to be played.

The offset is relative to the combining node's zero-time, so the input node's time of 0 is equal to its (start + offset) relative to the combiner node's start.

Any nodes passed-in will be deleted by this node when required.

clear()

void tracktion::engine::CombiningAudioNode::clear

getAudioNodeProperties()

void tracktion::engine::CombiningAudioNode::getAudioNodeProperties ( AudioNodeProperties &  )

overridevirtual

Implements tracktion::engine::AudioNode.

visitNodes()

void tracktion::engine::CombiningAudioNode::visitNodes ( const VisitorFn &  )

overridevirtual

Implements tracktion::engine::AudioNode.

purgeSubNodes()

bool tracktion::engine::CombiningAudioNode::purgeSubNodes ( bool  keepAudio, bool  keepMidi  )

overridevirtual

Tells the node to delete any sub-nodes that don't produce the required type of output.

This optimises out any unplayable bits of the audio graph. Returns true if this node should be kept, false if this node can itself be deleted.

Implements tracktion::engine::AudioNode.

prepareAudioNodeToPlay()

void tracktion::engine::CombiningAudioNode::prepareAudioNodeToPlay ( const PlaybackInitialisationInfo &  )

overridevirtual

tells the node to initialise itself ready for playing from the given time.

This call may be made more than once before releaseAudioNodeResources() is called

Implements tracktion::engine::AudioNode.

isReadyToRender()

bool tracktion::engine::CombiningAudioNode::isReadyToRender ( )

overridevirtual

Implements tracktion::engine::AudioNode.

releaseAudioNodeResources()

void tracktion::engine::CombiningAudioNode::releaseAudioNodeResources ( )

overridevirtual

tells the node that play has stopped, and it can free up anything it no longer needs.

Implements tracktion::engine::AudioNode.

renderOver()

void tracktion::engine::CombiningAudioNode::renderOver ( const AudioRenderContext &  )

overridevirtual

Implements tracktion::engine::AudioNode.

renderAdding()

void tracktion::engine::CombiningAudioNode::renderAdding ( const AudioRenderContext &  )

overridevirtual

Implements tracktion::engine::AudioNode.

prepareForNextBlock()

void tracktion::engine::CombiningAudioNode::prepareForNextBlock ( const AudioRenderContext &  )

overridevirtual

Reimplemented from tracktion::engine::AudioNode.

renderSection()

void tracktion::engine::CombiningAudioNode::renderSection	(	const AudioRenderContext &	,
		legacy::EditTimeRange
	)
